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.

• 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.

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.
