Finger pulse oximeter MD300С23

Oxygen saturation (saturation) is the percentage ratio of the amount of oxygen-bound hemoglobin (HbO2) to the total amount of hemoglobin (Hb) in the blood.

The oxygen saturation norms in a healthy person are recognized as readings from 95 to 98%.

It should be noted that the saturation readings change during the day.

Many respiratory diseases can lead to decreased oxygen saturation in a person's blood.

In addition, oxygen saturation can be reduced by factors such as anesthesia, severe postoperative trauma, and side effects of certain diagnostic tests.

Therefore, for a timely diagnosis by a doctor, it is very important to know the amount of oxygen saturation in a patient.

The Little Doctor MD300C23 hand held pulse oximeter is designed for continuous, non-invasive measurement of arterial hemoglobin oxygen saturation (saturation) and pulse rate.

Designed for home use.

The principle of operation of the Little Doctor MD300C23 pulse oximeter is based on the fact that oxyhemoglobin (hemoglobin saturated with oxygen, HbO2) and deoxyhemoglobin (oxyhemoglobin, which gave up oxygen to the body's cells, HbR), present in the blood have different absorption of light in the red and infrared regions of the spectrum.

The device makes a measurement on the finger.

At the bottom of the device there are two LEDs that alternately emit light in the red and infrared regions of the spectrum.

In the upper part there is a sensor with a photosensitive element that registers radiation transmitted through the finger.

By analyzing the absorption of red and infrared radiation, the saturation value is calculated.

The pulse rate value is obtained by analyzing the pulse wave, which characterizes the heart rate over time.

The results of the analysis are displayed on the oximeter in the form of values ��of the saturation level and pulse rate.

Large bright numbers on the display are clearly visible in any light, the brightness is adjustable.

Information can be displayed in 6 preset modes.

The device is equipped with sound indication.

The direction of the display can be changed by pressing a button, which contributes to ease of use depending on who is taking the measurement.

For diagnostics, the user just needs to place one of his fingers in the device, and the measured value of hemoglobin oxygen saturation will be shown on the display for 5 seconds.

The control panel is represented by just one on / off button.

The device is completed with AAA batteries (2 pcs).
