Pulse oximeter is a device that measures the saturation of oxygen blood. It is simply the amount of oxygen that circulates through the blood.
You should know that the blood is enriched in oxygen at the level of the lungs thanks to the hemoglobin (protein which is within the red blood cells).
Hemoglobin captures oxygen to distribute it to the different cells of our body to ensure their proper functioning.
The oximeter has a transmitter and a receiver.
The transmitter sends a red and infrared light, of course, these lights have no impact on our health. The light crosses the end of the finger and the receiver receives the rest of the light after its blood absorption.
Indeed, hemoglobin has the capacity to absorb the light sent by the oximeter as a function of its oxygen content. The more oxygen's hemoglobin, the more it absorbs light from the device.
It is thanks to these different measurements that the oximeter displays the rate of saturation of the oxygen blood.
Oxymeter is often used in the elderly, patients who suffer from respiratory diseases such as asthma, COPD, L'pulmonary emphysema, La Covid, ..., but also in people who are affected by anemia or the diabetes or cardiovascular diseases (high blood pressure, heart failure, ...).
The oxygen blood saturation rate of a healthy adult is between 100 % and 95 %.
When this rate is less than 95 %, it is respiratory failure, if it is less than 90 %, the person is in respiratory distress, it is a vital emergency, his life is in danger.
The oximeter is generally placed at the end of the finger (index, major or annular). Some models also allow it to be placed in the toe, nose or ear wings.
Finally, the oximeter also measures the heart rate (number of heartbeat per minute) which is a good indicator to assess the functioning of the heart.
This pulse oximeter is very useful to quickly detect a respiratory or heart disorder and save the life of a person in danger.
The use of this device is very easy.
