This video describes what a Pulse Oximeter is and how it detects the blood oxygen saturation SpO2.
With health and safety becoming a top priority, especially with COVID-19 being so prevalent, people are looking for ways to manage their health at home. Medical devices such as pulse oximeters have become essential for personal health monitoring.
---- What is a Pulse Oximeter? ----
A pulse oximeter is a small, clip-like medical device. It attaches to a body part, most commonly to a finger. A pulse oximeter uses a non-invasive method for monitoring a person's blood oxygen saturation (as opposed to measuring oxygen saturation directly through a blood sample). It can rapidly detect even small changes in oxygen levels.
----- How does a Pulse Oximeter Work? ------
Pulse oximeters use a noninvasive method for monitoring a person's oxygen saturation, which is a measure of the percentage of oxyhemoglobin (oxygen-bound hemoglobin) in the blood.
Pulse oximeter utilizes the principle that oxyhemoglobin (oxygen-bound hemoglobin) and deoxygenated hemoglobin (that does not have oxygen bound to it) have different absorptions for different wavelengths of light.
A sensor device is placed on a thin part of the patient's body, usually a fingertip, earlobe, or an infant's foot. The device emits light in two wavelengths through the body part to a photodetector on the other side, which detects and measures the changing absorbance at each of the wavelengths. Oxyhemoglobin and deoxygenated hemoglobin absorb light of the two wavelengths in different ways. Thus, the device detects the amount of oxyhemoglobin and deoxygenated hemoglobin in arterial blood and shows it as Oxyhemoglobin saturation (SpO2), which is an indirect estimation of arterial oxygen saturation (SaO2).
----- What is a good Pulse Oximeter Reading? ------
Your pulse oximeter will show you your oxygen level as "SpO2." Normal oxygen levels are at least 95%. Some patients with chronic lung disease or sleep apnea can have normal levels of around 90%.
If your SpO2 level is less than 95%, you need to visit a doctor, as it may be an indication that you may be suffering from hypoxia, a condition that requires observation and treatment.
--------- What are the two readings on a Pulse Oximeter? --------
Blood Oxygen Saturation (SpO2): The measurement that indicates what percentage of blood is saturated.
Pulse Rate: Pulse rate is nothing but the heart rate that indicates the number of times a heart beats per minute.
