Santamedical SM-1100S

Easy to Use, Easy to Read

Are you looking for a reliable pulse oximeter that will provide you with precise information about your heart rate and blood oxygen saturation level without varying between readings? If so, then the Santamedical fingertip pulse oximeter should be right up your alley. It is compact, lightweight, and it provides accurate readings in less than a few seconds. A great device either to keep at home for regular check-ups or to take with you for use on-the-go. For example, it can be especially useful for mountaineers who need continuous monitoring of their health condition while conquering new heights. To make sure you won’t lose your pulse oximeter, the manufacturer has put a wrist strap in the box so that you could carry your little assistant on your wrist or attach it to your backpack.

As for usability, this model offers simple one-button operation and a large OLED display that outputs measured data in three ways: numbers, waveforms, and bar graphs, and in 4 directions so that you could read them easily from any angle. To change the direction of readings, just press the on/off button. The screen itself is quite bright and easy to read, making it well suitable for people of different age.

Speaking of design, the Santamedical pulse ox is produced from high-quality, soft-to-the-touch materials. Its finger chamber is made from hypoallergenic medical-grade silicone free from latex. So, it can be safely used by children as well (from 10 years or so).

The last but not the least thing to mention is the power supply. This oximeter works on 2 AAA batteries that guarantee about 30-40 hours of flawless operation. Additionally, the automatic shut-off function ensures that batteries won’t die soon.

The Additional Measurement

The Santamedical SM-1100S gives three readings on the screen. They come in large figures so they can be easily read by anyone. Two of these readings are pulse rate and and SpO2 results, and the third one is a graph (or rather a waveform), called a plethysmograph, that shows changes in blood volume. The wave itself shows the heartbeat, while the amplitude of a plethysmograph demonstrates how much blood is detected in the blood vessels at the moment of taking a reading. Not all pulse oximeters have this feature.

To wrap things up, this pulse oximeter by Santamedical is a durable and reasonably-priced device that offers a bit more than many other models on the market. User-friendly and accurate, it has all the markings to become your reliable assistant in monitoring your health condition.

Innovo Deluxe

Small Lifesaver

The Innovo deluxe fingertip pulse oximeter is a great model to keep hand on pulse of your heart condition. Primarily designed for non-medical use only, it slowly but confidentially made its way to medical facilities and now is widely used by many people around. It is so not without a reason. The Innovo deluxe fingertip pulse oximeter is loaded with useful features and can measure heart rate, SpO2 levels, blood volume, and pulse strength, providing accurate data for each of the readings.

A bright OLED display is another thing we like about this pulse oximeter. It's well-lit and well-readable, and it allows for adjusting its brightness, making it possible to read it even at night without turning the light on. What adds convenience is that the oximeter provides six different layouts so you can set the optimal one for your eyes.

In terms of design, we like the size of the ox. It's small and rectangular, making it easy to carry it in your backpack and use on the go if ever the need be. The only thing we find a bit off-putting is the choice of color for the housing of the thing: matte white does tend to attract dust and dirt. Other than that, the ox looks nice and modern. It isn't as clumsy as most medical equipment of like ilk and it is very convenient to grip. Plus, it's very easy to use. You have an auditory alarm that will warn you in case the measurements go beyond set limits, an auditory beep for every detected pulse, and an automatic shut-off feature to save the charge of batteries.

Bonus Feature

As a bonus, this pulse oximeter can also measure perfusion index (PI), the reading you'll find between SpO2 level and the heart rate. This figure should be 0.2% or higher, or the result will not be correct.

Summarizing everything said above, the Innovo pulse oximeter doesn't lack in functionality and provides every feature you'd expect a pulse oximeter to have. For anyone who care for their health, as well as sport enthusiasts involved in mountaineering, athletics, aviation, etc., this ox is a great deal.

AccuMed CMS-50DL

Good Quality for Nice Price

The AccuMed oximeter is made accurate, durable, and reasonably priced. It has a lean and mean design that offers one-button operation and is available in several color options.

This model has a quite large LCD display which shows the oxygen saturation level, the rate, intensity, and strength of the pulse. The response of the probe is quite fast, and you'll get your results in around 8-10 seconds. The display also shows the charge of batteries so you can see when it's time to replace them. Speaking of which, this oximeter holds charge pretty well and the batteries last long enough to provide up to 24 hours of continuous monitoring.

It's worth mentioning that the display on this device is non-rotationable which is perhaps the only inconvenience you may face. However, the company offers its oximeters in other designs as well so if you need that feature, you may buy yourself an AccuMed oximeter with an OLED display with auto screen rotation and brightness adjustment.

Now, the thing we do like about the CMS-50DL is a finger chamber. It's not too small and not too large and can fit fingers of both children and adults.

The package of the CMS-50DL is also great. This model comes with a set of batteries, a wrist strap, and a protective case, allowing you to neatly store it and transport, so you get everything needed to start using it out-of-the-box.

The CMS-50DL is definitely a good pulse oximeter to consider if you're searching for an inexpensive model from a reputable brand. For a more than affordable price, it offers all the features and functionality you'd want your pulse oximeter to have. If you're an athlete, gym goer, or simply want to have the means to monitor your hearth health at home, it's your best choice.

Review of AccuMed CMS-50DL Finger Pulse Oximeter

More Accurate Results

Pulse oximeters operate by emitting the infrared light that penetrates the skin to take a reading. This allows them to take precise readings. The AccuMed CMS-50DL is not an exception. Using it, your results will be with ±2 bpm and ±2% precision rates. That said, you still can do a few things to improve the accuracy of your pulse oximeter. Here are some of the main recommendations:

  • Make sure your hands are clean and dry before making measurements;
  • Nail polish prevents the sensor from proper hemoglobin detection. So, it is better to remove it in advance if you have the opportunity. If not, place the finger clip sideways to avoid the polish;
  • Try to sit still during the procedure;
  • Always warm up your hands before you start;
  • Keep the unit in a carrying case and use it away from direct sunlight. The former precaution will increase its shelf life. The latter won’t let bright sunlight and infrared rays interfere, thus giving you faulty results.

By following these simple instructions, you'll make sure that your results are always accurate and you can trust them 100%.

Comparison of Pulse Oximeters

What Is a Pulse Oximeter?

A pulse oximeter is a medical device used by a great number of people who'd like or need to keep track of blood oxygen levels. A few days without food or water won't be good but won't kill whereas lack of oxygen even for a couple of minutes means instant death. Human body needs oxygen all the time to function properly so oxygen saturation should be measured from time to time to know deviation from norm and provide oxygen in due time. Pulse oximeter has been designed exactly for this purpose. Taking oxygen level readings is now possible without blood tests, all you need is this device at hand. Owing to the infrared light, the device can quickly detect oxygen saturation and reflect the readings back on a screen.

What Features to Compare

If you're planning to buy a pulse oximeter, you need to consider some of the key features that will help you make your choice. Here is everything you need to know about pulse oximeters before making the final decision.

Type

There are two most common types of pulse oximeters: stationary and portable.

A stationary pulse oximeter is quite bulky and widely used in hospitals. It can be a fetal pulse oximeter or a tabletop model with sensors. These devices give highly accurate results, provide long-term monitoring of patients, and deliver information in graphs.

Portable pulse oximeters, on the contrary, are best for home use.

  • There are finger pulse oximeters that are the most popular models for use on-the-go.
  • The handheld devices have a probe connected to the screen, they are a bit larger than fingertip ones.
  • Wrist-worn sensors are good for continuous monitoring while you are sleeping, for example.

All portable models are compact, light in weight, and simple to use with no special skills required.

Specifications

Once you’ve decided on the type of a pulse oximeter you’d like to purchase, the accuracy should be the next feature to check. Without a doubt, when it comes to your health, heart condition, in particular, the accuracy of readings can become a lifesaving factor.

Display is the next important feature on the list. Since after making a full set of measurements, the obtained information is shown on a display. Hence, an easy-readable screen would obviously be an added advantage. If you are going to use a pulse oximeter at night, it won’t be a waste to check the level of brightness. Some models allow a user to adjust the brightness according to the lighting condition in the room.

A pulse oximeter can also come with different alarms. For example, it can beep when oxygen saturation is low. It's a quite handy feature, especially if you don’t have a medical background.

Design

When it comes to the design of a fingertip pulse oximeter, the most important feature is the size of the probe because the result may not be precise if it doesn’t fit your finger snugly. So, measure your finger and check whether it's well-suitable for a chosen device.

You may also want to check the material the finger chamber is made from. For example, if you have an allergy for latex, you will be glad to know that some manufacturers produce pulse oximeters from hypoallergenic medical grade silicone.

The last but not least is the usability of a pulse oximeter. One-button control, a multi-directional display, self-adjusted fingertip chamber, wrist strap, and carrying case... all these things make the use of the medical device more convenient.
