Basic knowledge about a pulse oximeter:

As we all know, the level of oxygen saturation is an important index for the health of the lungs. Pulse oximetry is a noninvasive and painless method of measuring the oxygen saturation of the blood. Fingertip pulse oximeters are routinely used, from regular physical check-ups to surgery. Do you wonder how a fingertip pulse oximeter exactly works? Such a small electronic device utilizes a cold light source that can emit light through the fingertip. That is why the fingertip appears to be red when the fingertip pulse oximeter is clipped onto it. And the device’s sensor can accurately detect and measure the light that passes through the fingertip without being absorbed by the blood and tissue; through this approach, the device can calculate the amount of oxygen in red blood cells (red blood cells carry the oxygen around a body for aerobic respiration).

A fingertip pulse oximeter integrates the blood oxygen level detector, data processing module, and displaying module into one. It has the advantages of small size, low power consumption, ease of use, lightweight, and portability.

Product description:

The OLED/LED display board clearly shows the real-time wave graph according to the accurate data. The perfusion index is particularly designed to reflect the pulsation flow. All the operations can be completed with one button. The size of the fingertip pulse oximeter is so small that you can carry it around. This device is quite suitable for everyday use; with it, you can better monitor your health whenever and wherever you like.

According to customers’ feedback, our fingertip pulse oximeters are often used in families, hospitals, and communities. The main user groups of this product include people who travel at high altitudes, patients who need to recuperate at home for a long time, mountain climbing enthusiasts, old people aged over 60 years (low oxygen levels and shortness of breath are two typical symptoms of old people’s respiratory diseases), athletes (in extreme sports and the plateau environment where the lack of oxygen is serious, blood oxygen level monitoring is very necessary for athletes. By observing blood circulation after sports, athletes can receive more valuable guidance based on more comprehensive data), sports fans, people who work extremely hard for long hours (this group of people is particularly apt to experience episodes of brain hypoxia), and people who have to work in enclosed spaces.

Functions and features:

  • The parameters that the screens display include: SpO2 value, pulse rate value, bar chart for blood oxygen saturation levels, wave graph for pulse rates, perfusion index, and respiratory rate.
  • Displaying ways are flexible: the rotatable multi-direction display allows you to check data in 4 directions, and 6 displaying modes;
  • It is energy-saving: the power consumption is low; it can work for more than 40 hours on 2 AAA batteries.
  • You will receive a low voltage warning: once the battery drops below a threshold, the pulse oximeter will alarm automatically.
  • It can shut down automatically: if it has not received any signal within 8 seconds, it will power off automatically.
  • It can monitor your night sleep: do you think it is expensive and inconvenient to conduct a full-blown sleep study? With this advanced pulse oximeter, you can monitor your blood oxygen (SpO2) levels as you sleep during the night. Overnight pulse oximetry is proven to be a beneficial and effective technique to determine a patient’s cardiorespiratory status in both outpatient and inpatient settings.

What you need to know about its major parameters:

SpO2: SpO2 also refers to oxygen saturation level, the normal oximeter reading for oxygen saturation level ranges between 95% and 100%. If the value drops below this range, probably the user is experiencing symptoms related to lack of oxygen, such as difficulty breathing and mental confusion.

If the value drops below 92%, especially if the value is obviously under 90%, that is worthy of concern. For people living at high altitudes, it may be normal to have an oxygen saturation level that falls below 90% (high altitudes can inevitably cause low blood oxygen levels or even blood oxygen desaturation); but in general, when it comes to a significant low level, the user might need supplemental oxygen or might be advised to stay in the hospital for further observation. In other words, the SpO2 value is an important parameter that can be used for observing disease progression, lung function, and how well certain therapies are working.

Pulse rate: pulse rate (also known as heart rate) is the number of times each minute a person’s heart beats. For adults, the normal resting heart (when not exercising or not excited) ranges from 60 to 100 BPM (beats per minute). In general, a lower resting heart rate means more efficient heart function; the fitter a person is, the lower their resting heart rate is. For example, a lot of athletes have a resting heart rate of 40~60 BPM.

Perfusion Index: this is often abbreviated as PI; this value reflects the ratio of the pulsatile blood flow to the non-pulsatile blood flow in the peripheral tissues; more exactly, it measures the strength of the pulse at the part of the body where the pulse oximeter is placed. The higher the value is, the better the blood can flow through the body. The significantly low value can signal health problems associated with blood vessels or hearts. The normal PI ranges from 0.02% (for very weak pulses) to 40% (for very strong pulses). The PI values are relative numbers and can vary depending on physiological conditions and monitoring areas.

Moreover, perfusion index readings also have a strong correlation with the core-to-peripheral temperature gradient as well as the refill time of capillaries. Therefore, in the majority of hospitals, PI is just used along with other parameters to monitor a patient’s overall health status. For the correct monitoring purposes, a patient may need to establish his/her own “normal” perfusion index range in a given situation.

Frequently Asked Questions:

  • “I have compared your product with other professional pulse oximeters, but it looks like the data is not very accurate.”

As we all know, blood pressure is constantly changing, it can fluctuate every time the heart beats. And the same applies to oxygen saturation level and pulse rate. As we have just mentioned, whether for SpO2 data or pulse rate data, the range of accuracy of our pulse oximeters is controlled under ± 2%; moreover, the data can also vary from the part of the body; it is normal.
In terms of our oximeters’ reliability and accuracy during clinical tests, the generated data is trustworthy.

The 2 videos below can make this point very clear to you:

(When clipped on different fingertips, the pulse oximeters may display different sets of data)

(This customer gives an on-site comparison between our pulse oximeter and a hospital-based pulse oximeter)

  • “Why does not my fingertip pulse oximeter show data?”

Like the image, as long as circle-1 is still fluctuating, it proves the product is working normally. And look at circle-2, it shows the batteries are running down; in this case, you need to replace the batteries because the current power is not strong enough to make the pulse oximeter run all the functions normally.

  • “Which finger is the most suitable for testing?”

In general, you might opt for your relatively thin finger. But if your fingers are too small, that is another matter; in such a situation, you might consider a relatively thick finger, such as your thumbs or forefingers. In addition, to make it easy for your pulse oximeter to sense your skin to give the measurement results quickly, you need to put your finger inside the oximeter as much as possible.

  • “Does nail polish influence the accuracy of a result, do I have to remove it?”

Yes; nail polish and fake fingernails can affect the oximeter’s ability to provide a correct reading. If possible, you might consider another application site or switch to an unpolished fingernail.

  • “Does your device support Bluetooth?”

By default, our pulse oximeter are designed without the Bluetooth capability. But if you want ones with Bluetooth, we can also design them according to your needs.

  • It looks your fingertip pulse oximeters have multiple models, so what is the difference between them?

In fact, they have the same functions and parameters; the difference just lies in the appearance design. And to help you easily distinguish among them, it is necessary to show again the pictures of our IMDK A2, IMDK A3, IMDK H1, and IMDK B1.

  • Can the oximeter be used for infants?

Sorry, this type of oximeter belongs to adult pulse oximeters, not pediatric pulse oximeters; in other words, our fingertip pulse oximeters are not suitable for infants and young children.

  • “Can you provide OEM services? I want to customize the package with our logo brand?”

Yes, we can; but the minimum order quantity should reach 500 pieces.

  • “It looks that your oximeters just provide 3 major parameters – SpO2, PR, PI; but we also want to monitor RR (respiratory rate) from oximeters, so can we customize oximeters with this parameter? ?”

Yes, we can manufacture oximeters that have all 4 parameters, it just depends on your needs; currently, the majority of customers do not use oximeters to measure respiratory rate, so we default to providing oximeters with SpO2, PR, and PI;

Here is an example:

  • “What is your minimum order quantity?”

No minimum order quantity; even if you just want to buy 1 piece, we can offer you the product at a fair price. As we are a manufacturer, we are sure that our prices are competitive. Surely, the price depends on your order quantity – the more you order, the more fair the price will be.

  • “I run an online store; can I set up a dropshipping partnership with you?”

Yes, we welcome any form of partnership;
