Getting Accurate readings from an oximeter
Even if the oximeter is functioning perfectly without any fault, you might at times end up with wrong and inaccurate results if you do not follow the procedure. Therefore, the following points must be followed in the quest for accurate readings.
Remove the nail polish
The nail polish similarly blocks the oximeter functionalism by absorbing the produced light. As a result, the information that you would receive would be inaccurate.
Since the gadget operates by emitting the light, exposing it again to excess light when in use would interfere with the light from the system leading to inaccuracy.
Stay still when using the oximeter
It is advisable to avoid moving the body parts when taking the readings for a perfect and accurate result. However, even when measuring the level of oxygen while exercising, you need to stay still when taking the readings.
How To Choose A Pulse Oximeter
Before making any purchases it is always prudent for one to compare prices. One can choose to compare the prices being offered by different manufacturers and outlets for oximeters that bear similar features. This will go a long way to assist in getting the best deal in the market at the time. It will also ensure that a buyer gets good value for their money.
Accuracy is actually among the reasons one gets to buy an oximeter. Given the nature of the tests it conducts any wrong results could be detrimental to the health of the user. This is because any action taken after the results are displayed in highly reliant on the results. This therefore calls out for testing before making a purchase to ensure that the oximeter displays accurate results.
It is important for a buyer to look out for what is relevant to their needs. Manufactures have in the recent past been putting up additional features. Such features increase the functionality and reliability of an oximeter. Get the one that has the best features that match the needs of the user.
Any oximeter with a clear display will make your work easy. That is one of the main reasons why manufacturers have introduced LED displays complete with background lighting. This enables a user to see the results displayed on the screen under any lighting conditions.
The content displayed by the oximeter is also a feature to look at. Most of the oximeters will show the blood oxygen saturation level and the pulse. However newer versions have additional information displayed on the screen. Such additional information could include the pulse meter, the pulse waveform, and the perfusion index value and so on and so forth. This depends entirely on the use, some will prefer additional menus while others will prefer the simple oximeter.
This is highly connected to portability and ease of use. Depending on its use, one should get the appropriate weight of an oximeter. This also goes to the type of user. For instance oximeters t be used on children need not be heavy. Again if the user is one that travels or moves a lot then they need a light oximeter.
Alarms will play an important role in informing the user of important issues. The user is able to set what they need to be reminded of. For instance one could set the alarm to ring whenever they exceed a certain heart rate or when the oxygen in their blood level falls below a set level.
How Pulse Oximetry Devices Work
The way Pulse oximeters work is very simple. First, the device clips onto a fairly transparent part of the body such as a finger, toe, or earlobe.
Next, once activated, a light is emitted from the probe side of the oximeter and a light sensor is located on the other side. The light emitted consists of two distinct wavelengths of light (650nm and 805nm). Light is absorbed by both the hemoglobin in our blood and the oxygen molecules that may or may not be attached to them.
High Altitude Sports
A pulse oximeter can alert you to oxygen deprivation issues before they become a serious problem. Sports like mountain climbing, skydiving, hang gliding and any other sport or activity that puts a person in high altitude situations can benefit from the use of a pulse oximeter to determine arterial blood oxygen levels.
Piece of Mind for Pulmonary Patients
Aside from those already mentioned, there are several common and many rare pulmonary conditions that affect the lungs, and which can be life threatening. Those suffering from such conditions can definitely benefit from the use of a pulse oximetry device, to alert them of changes to their arterial blood oxygen levels before life threatening complications occur.
Once calibrated, pulse oximeters will work the same after two years as they did on the first day they were opened. All these devices perform a startup check of their circuitry when turned on, and will not run a scan unless they pass these built in tests. No calibration is ever needed, or even possible, with an at home oximetry device.
Less Invasive Than Blood Gas Testing
For some people, going to a lab and being poked with a needle is a major source of anxiety. This is particularly true if you have to go for regular blood work and calluses have developed in the preferred extraction sites, making taking your blood not only frightening, but also extremely painful, too.
How to Use a Pulse Oximeter Properly
This section could also be titled “What Not to do When Using Your Pulse Oximeter.” Oximeters are very easy to use. Simply clip the device on your fingertip or earlobe (you can attach the clip over the wrist or top and bottom of the foot on infants), then turn the device on to take a reading. This is the easy part. • Painted fingers and toenails can obstruct proper readings – use an earlobe instead in this case. • Bright overhead lighting, including sunlight can effect readings – take your readings in rooms with normal or low-light conditions.
There are warning systems that you want to look for when choosing an oximeter: • Low Battery: Whether this is an indicator or a noise, a low battery indicator is important for those who rely on an oximeter for disease management.
For People With Dark Skin
This problem can be overcome by placing the sensor on an earlobe or, if possible directly on the wrist (if your wrist is small enough). The pigmentation in these areas is usually light enough to accommodate reliable readings.
Go to the Emergency Room if
Neonatal Pulse Oximeters
The definition of neonatal refers to newborns, usually up to one month after birth.
After a baby is born, it’s important to make sure that they’re healthy and born without any major birth defects.
One of the many measurements taken is pulse and oxygen level thanks to neonatal pulse oximeters.
These, obviously, need to be much smaller than an oximeter for an adult or even an older child to properly fit their toes or fingers.
It’s important to note that the readings from these for newborns should be taken at least 2hours from birth. Anything earlier than that can create false positive readings.
This is the type of oximeter that you’re more likely to find in an ER or hospital. Instead of the display being on the clip of the oximeter, it’s on a box connected to the clip by a cable.
This type of oximeter shows more than just the oxygen and heart rate, however, the exact other readings may change from model to model.
This is because this type of oximeter is meant to be used by doctors to help make a full diagnosis rather than just test for a symptom.
Brands are another important thing to look out for. Well-known brands help us choose companies and products we can trust that will stand the test of time. In this section, we’ll take a look at some of the best brands on the market right now.
AccuMed is a well-known medical company that focuses on engineering medical products.
Not only does this count the pulse oximeters that we’re looking at here, but other products such as slings, wraps, and headgear for sleep apnea.
Since their products are made to be used directly on the body, they’re made not only to work but to be comfortable as well.
This sort of innovation and forethought has made AccuMed a trusted name in the medical equipment industry.
Vive Health, or simply Vive, is a company that states their mission as a rebellion against age.
However, their products help people of all ages stay healthy and deal with ailments with ease.
They’re an online retailer with a large number of followers and a focus on customer service.
Better yet, especially for young families looking for paediatric equipment such as these oximeters, they offer their customers all this innovation without making them completely empty their wallets.
It’s the perfect size for older children.
Unfortunately, the size of it is too large for very young children, leading to inaccurate readings.
The digital display on the oximeter is also large and easy to read.
It only takes seconds to take a reading, so you can get results quickly without any fuss.
It has also been praised for its high accuracy, so you don’t have to worry about mistakes.
Acc U Rate Children Oximeter
This children’s oximeter is small enough to take children’s measurements and in the fun shape of a polar bear.
It’s specifically designed to fit children’s fingers from the age of two and up.
This model also includes a plethysmograph. This indicates the amount of blood flow and blood pressure, so you have added accuracy.
The OLED, rotatable display also makes it easy to read.
It also comes with a free pouch and lanyard to make it easier to carry and store, as well as AAA batteries so you can use your new purchase immediately.
AccuMed CMS-50DL Oximeter
This oximeter is unique since it can fit both children and their parents.
It’s intended for use by sport and exercise enthusiasts, rather than made for a hospital setting, but is extremely reliable all the same.
The screen of this oximeter is easy to read as well with digital display and protections against ambient light.
It also comes with batteries, a lanyard, and a carrying case which helps owners store and carry the device.
A reading with this oximeter only takes a couple of seconds to provide an accurate and quick reading.
Thanks to a one-year warranty, you can rest easy knowing that your oximeter is protected.
First up in our search for the best finger blood pressure monitor is the CMS 500DL Pro Series from Acc U Rate. The CMS 500DL Pro Series came into existence as a result of the public’s dissatisfaction with Acc U Rate’s original CMS 500DL finger blood pressure monitor. Customers complained that it was unreliable, ineffective, and flimsy.
Acc U Rate owned up to its mistake, listened to customer feedback, and went back to the drawing board. Acc U Rate’s decision to listen to its customers proved extremely beneficial as the newly designed CMS 500DL Pro Series has become incredibly popular.
Unlike its predecessor, the CMS 500DL Pro Series offers consistently accurate readings, the kind you would expect from a wrist or upper-arm blood pressure monitor. It is designed to be used by hikers, runners, and anybody else who might need a reading while on the go. A large LED display makes it possible to read your results outdoors, regardless of the weather or the time of day.
TemplR Finger Pulse Oximeter
This finger blood pressure monitor from TemplR has the ability to give you an accurate reading in almost no time at all. It is one of the more easy to use finger blood pressure monitors on the market and requires only the push of a button to measure your blood pressure.
Furthermore, a rotatable dial allows you to read your results from any angle; a seemingly insignificant though undeniably useful feature.
Santa Medical Generation SM-165
Reviews of the Santa Medical Generation SM-16have been extremely positive, and it isn’t hard to see why. Much like the finger blood pressure monitor which started off this list, the Santa Medical Generation SM-16is an improvement upon a previous release, although the predecessor to this one was a success in its own right.
The new and improved finger blood pressure monitor from Santa Medical features increased accuracy in its readings, which, by the way, are processed and presented with greater speed than ever before.
The Santa Medical Generation SM-16is lightweight and portable, even for a finger blood pressure monitor, and can be easily taken with you on hikes and runs. It will be particularly beneficial for those who are away from home for days at a time as it features a long battery life.
Things to Consider
Once you’re done digesting all this info and have a monitor in mind, you may want to hop onto Bandalou for a deal. (You can also find my review here.) They’re a new crowdsourcing site that uses the power of social buying groups for baby products.
Every time you crowdsource & buy, Bandalou rewards you with savings. The more you shop and socialize, the more you can save because the more people that want it, the better the deal is. Ah, the power of a community shopping together! It’s that simple.
It’s great because you can decide if you want to take them up on the offer, or pass. And the other great thing is that Bandalou is 100% curated by parents. So you can see what other parents are digging – especially if you’re just browsing and not sure of what you want.
I’ve staked a claim that 201is officially The Year of Moving About a Bit More. With the huge number of fitness trackers available today, there’s simply never been less of an excuse to keep on top of your general health.
The Withings Pulse Ox is an intuitive device than can be used as both a band and, once removed from its strap, a clip-on tracker, like the original Fitbit that kickstarted this whole crazy “fitness tracker” thing.
It’s easy to use straight out of the box, and charges very quickly. We’re talking “shower and breakfast” quickly, and via a very discreet micro USB charging cable, rather than a comically enormous charger, as found on certain other devices. Just attach it to your laptop and leave it to juice.
Even better, once fully charged, it’ll last well over a week before you need to plug in again.
The heart of the device is a lightweight rectangular box, which comes with a choice of blue or black straps. I had the blue version, which had the vibrant sheen of a Lumia smartphone. The pebbly unit fits very securely into the strap’s casing and I didn’t have any worries about it falling out – and, indeed, it didn’t. It’s not as discreet as the aforementioned Garmin VivoSmart band, but I quite liked it and it was comfortable enough throughout the day, although maybe a bit bulky in bed.
If you don’t want to wear it as a watch at all, you can attach it to your waistband, collar or underclothes. The only real thing that was a bit disappointing from the outset was to find out it’s not water resistant. You just kind of expect to not have to take this sort of thing off in the shower, which is easy to forget after a gym session. It hardly alone in this respect but it is an irritant.
In one way this is excellent: there’s no complicated configuration – just fill in a few details about your age, weight etc, and there’s handy tour guides aplenty – and you quickly feel at home working the device and app in tandem.
In another way, it’s quite limiting: the info available, though beautifully presented, is quite basic, and you can’t really delve into it – the graph showing your steps would feel so much more useful if you could “zoom in” to a specific period of activity.
Them’s the breaks with fitness wearables, though: you either get an expensive running watch that tells you everything you could ever want to know about, or you get something that tells you how many steps you’ve taken, more or less.
Step to it
So what does it do? The rarer features of the Ox are a simple run analyser, heart rate monitor and blood oxygen level monitor and an altimeter to measure elevation. On top of that, there are the fitness band staples: a step counter, distance tracker, calories burned advisor, and something that claims to track the duration and quality of your sleep.
Step counting, perhaps what most ‘move about a bit more’ folks will buy this for, seemed to be accurate – 100 manually counted steps was measured as near-enough 100 steps. The data was easy to read on the OLED touch screen when inside (and very bright in a dark room), which was consistently reactive when tapping and swiping around between data screens – more so than the Vivosmart.
However, it did prove trickier to read outside even in daylight, albeit very foggy British January “daylight”, and was very quick to go back to black (what you pay for such a long battery life), so you sometimes can’t really take in the data before it’s turned off again. It also provides motivation without being a pest; the Garmin VivoSmart would buzz regularly to order me to get moving, which begins to grate when you’re at work, in a lift, in the khazi, etc.
However, as seems to be the case with many general health trackers of this ilk, you should take the calories burned data with a pinch of salt. One one occasion, after 990 steps (9% of a daily goal of just 10,000 steps, and just under 1,000 metres of plodding) I was informed that I hand managed to burn off a whopping 2,16calories; after rudimentary calculation in my head I started to worry I’d either need to stop moving for the day (thereby putting paid to my plans to buy milk) or eat a slice of pizza for every couple of steps to ward off the chance of wasting away into a skeletal heap.
It wasn’t always as wildly inaccurate as that, but it never felt like it was erring on the side of understatement, and I wouldn’t use it as a guide to how much to eat if I were on a proper calorie-counting type diet. A Fitbit would be a better option there, for sure.
Run tracking is one of the Ox’s USPs, but I really couldn’t recommend such a casual device for, say, serious marathon training. It’s still disappointing, however, that one 10-miler was reported as 1miles and then not logged anywhere despite me clicking to save it.
Unlike most running watches, it tries to detect when you’re on a run, rather than you telling it so via a menu or button. That’s a great theory, but I found it assumed anything up the first mile was just a brisk walk, and carried on counting steps. This is not a fatal flaw as the device can be paired with popular apps Runkeeper and MapMyFitness to get round the issue. I don’t use these – I chose Endomondo in 201and can’t tear myself away – but millions do.

Santamedical Generation SM-16Fingertip Pulse
The Santamedical brand has become one of the most popular manufacturers of pulse oximeters throughout the years. Their Generation SM-16Fingertip Pulse Oximeter is one of their best models, featuring accurate measurements and convenient use for instant and reliable results.
Much like other pulse oximeters, the Santamedical Generation SM-16Fingertip Pulse Oximeter also features a rotational display that can be easily adjusted to make it easier to understand readings.
The single issue with this oximeter is that it might not be suitable for small children, considering that the size won’t be able to accommodate such small fingers.
Pulse oximetry is a technology used to measure the oxygen level in your blood and your heart rate. A finger pulse oximeter is equipped with technology to rapidly detect changes in your blood oxygen level.
You can use your oximeter to measure your oxygen saturation level at any time, such as at home, at work or during recreation.Patients with serious respiratory problems should have their oxygen levels checked regularly and especially if they are not feeling well.
Pilots, mountain climbers and people in high altitudes also use pulse oximeters to help guard against hypoxia.
There are many advantages and some disadvantages of using a pulse oximeter and here is an useful ARTICLE to read for more details on this.
Here is another INTERESTING READ about finger tip pulse oximeter history and what things to keep in mind while using oximeter.
These are the best Pulse Oximeter brands in India and are picked based on number of products available and popularity online.
Limitations of using a Pulse oximeter
The limitation of using an oximeter is that the devise only measures the amount of oxygen in the blood and not the consumption rate of the oxygen. The sale of oximeters over the last years has increased dramatically and if you notice the exceptional price of our devises you will see that the marketing curve of supply meets demand has allowed us to supply our customers with these great products at the best available price.
The human body needs oxygen to make energy. In case your body cannot get enough oxygen to your lungs, a series of complications can be developed. In all such cases specialists are going to recommend oxygen therapy. This is the administration of oxygen as a medical intervention. This extra oxygen is believed to be able to increase the body’s ability to destroy cells that cause various diseases. There are different types of oxygen therapies that can be administrated to patients, depending on their state. Some types of oxygen therapies are actually recommended as alternative treatments for a series of diseases. They may include even the most serious conditions, such as cancer, asthma, AIDS, arthritis, heart and vascular diseases. Multiple sclerosis and Alzheimer’s disease may also be listed here. Some researchers believe that oxygen therapy can kill cancer cells, which are known to not be able to survive in an oxygen rich environment. Oxygen therapy is also believed to be able to enhance the immune system and promote the production of antioxidants.
Oxygen therapy can be used in both chronic and acute cases. Depending on the needs of the patient, this therapy can be used in hospitals, clinics, but also as home therapy. Some people require supplemental oxygen in the room air for breathing. For these patients oxygen therapy can include various mask options or portable devices. However, it is important to keep in mind the fact that oxygen is in fact considered to be a drug. This means that it must be administrated under medical supervision. The physician will indicate the amount of oxygen a patient should receive, as well as the period of time over which the therapy has to be administrated. Oxygen can be delivered to a patient via mask or nasal cannula. Keep in mind that oxygen can be very drying to the nose. This is why special humidification bottles can be recommended by some specialists.
Negative effects Even though oxygen therapy can be extremely beneficial for patients, there can be situations in which this therapy has negative effects as well. For instance, oxygen should never be administrated to a patient who is suffering from parquet poisoning, as it may increase toxicity. Oxygen therapy is not recommended in cases of pulmonary fibrosis or lung damage. In some situations it may increase the effects of stroke, as well.
Oxygen therapy can be extremely beneficial for patients in certain situations, but this therapy should only be administrated under medical supervision.
The Many Uses of the Oximeters
In just over 80 years, pulse oximeters has gone from theory over utilisation. Just because a test or therapy is used frequently does not necessarily mean that it is useful. Pulse oximetry was first theorised in the 1930s and became a clinically useful tool for monitoring patients in the mid 1970s. Due to the size and expense of the equipment, however, its use was initially limited to pulmonary clinics, the operating room and post-operative services. It was only a decade later that these limitations could be resolved to make its use widespread in the field of emergency medicine.The utility of pulse oximetry measuring for the management of patients in acute situations is now focused in four main areas: improving triage classification, decreasing the use of ABG sampling, improving management and monitoring of acutely ill patients, and decreasing the length of stay in the ED. Pulse oximetres are useful for measuring oxygen saturation in the blood. Oximeters do not have the capability to measure pH or carbon dioxide. Assuming that the person has good skin perfusion, a pulse oximeter works the same at altitude as it does at sea level. As ambient atmospheric pressure decreases, the amount of oxygen in air decreases correspondingly. Respiration increase to help compensate for this. In general, resting saturations will continue as one ascents to a higher altitude. Oximetry can also refer to a test that can be easily be done at home. It provides basic information that may be useful in initially evaluating whether you have one of the more common sleep disorders, such as sleep apnea. The test involves applying a plastic clip over the end of your finger. The clip is connected via a cable to a small box that records the data overnight. Within the overnight oximeters clip is a red light. On the other side is a sensor that can measure your heart rate and the oxygen content of your blood. This screening provides a limited amount of information. In addition, there are subtleties involved in sleep disorders that it may not be able to detect. As you can see, there are many ways you can use this device.
History of Pulse Oximeters
Pulse oximeters were first developed half a century ago, but widespread clinical use of the oximeter only became practical with the advent of digital technology. The oximeter was commercially marketed in 1981, but use was largely restricted to critical care areas. More recently, pulse oximetry offers a relatively inexpensive, simple and reliable means to monitor respiratory function in a wide variety of clinical areas, in hospitals and the community. Traditionally, cyanosis has been relied on for detecting hypoxia, meaning that oxygen is reduced in tissues. Severe respiratory failure generally occurs when arterial saturation of haemoglobin falls to 85-90%, whereas cyanosis does not usually appear until saturation falls to 75%, the normal saturation of venous blood.Oximeteres are now a virtual fixture in intensive care units, pulmonary units and elsewhere in hospitals and health care facilities.
You might wonder how an oximeter functions. A pulse oximeter works by passing a beam of red and infra-red light through a pulsating capillary bed. The ratio of red to infra-red light transmitted gives a measure of the oxygen saturation of the blood. The device measures the sum of the intensity of both shades of red, representing the fractions of the blood with an without oxygen. The oximeter detects the pulse, and then subtracts the intensity of colour detected when the pulse is absent. The remaining intensity of colour represents only the oxygenated red blood. This is displayed on the electronic screen as a percentage of oxygen saturation in the blood.There is also other type of oximetry. Oximetry can also be done on blood that is within the heart or on whole blood that has been removed from the body. More recently, using similar technology to oxymetry, carbon dioxide levels can be measured at the skin as well. Pulse oximetry measurements may be affected by advanced age, irregular heartbeat, weak pulse or cold hands. Conventional pulse oximeters suffered greatly during motion and low perfusion and was made difficult to depend on when making medical decisions. The newest models of these devices can be easily used by all patients, as they have to placed on the finger. Their advancement in technology has allowed the device to also show venous and arterial blood. In some cases, monitoring oxygen is vital for both the comfort and security of a patient.
Oximeters Are Perfect For The Elderly
The oximeters are the devices that can help a lot of people in numerous instances. It is important to know how your heart rate and blood oxygen level shifts during the day, especially after a certain age, when these factors can be the indicators of a certain issue. The oximeters are perfect for the elderly, even if they have had some sort of health problem or not. The heart rate and the oxygen levels should be monitored as they can be the indicators of serious health problems, which may not manifest themselves directly from the beginning. There are many advantages which come with the usage of the oximeters at all times and especially after a certain age. In the case of older people, the health problems are bound to appear at some point or the other. For those who have lived healthy and naturally for their entire life, there may not be as many problems, yet it is still important to have all those regular checkups done just to be sure. With the help of the oximeters, even those who are healthy, not just the ones that are ill, will have a lot of benefits to make their lives better and less stressful. The oximeters can monitor the most important elements, which show if the organism is healthy or not. Therefore, the proper usage of the oximeters, in the case of healthy people as well, can aid the early prevention of any issue. The major changes in the heart rate and in the oxygen levels of the blood may indicate some problems, which should be taken to a specialist. The best thing about the oximeters is that they can keep a person healthy, just by providing a regular set of information on which all the most important bodily encounters are based. In addition to this, the oximeters are small devices and come in a variety of shapes, in order to be properly and easily adapted to your body and to your daily habits. The elderly can take their oximeters with them everywhere they go, without having problems created by their weight or size.
