pulssoksümeetri

Pulssoksümeetri, also known as a pulse oximeter, is a medical device used to measure the oxygen saturation of hemoglobin in the blood, as well as the pulse rate. It is a non-invasive device that uses light to measure the oxygen levels in the blood. The device consists of a small sensor that is placed on the skin, typically on the finger, earlobe, or forehead. The sensor emits light of different wavelengths, and a photodetector measures the amount of light that is absorbed by the blood. The oxygen saturation is then calculated based on the ratio of the absorbed light at different wavelengths.

Pulse oximeters are commonly used in clinical settings to monitor patients' oxygen levels, especially in intensive care units, operating rooms, and emergency departments. They are also used in home healthcare settings to monitor patients with chronic respiratory conditions. Pulse oximeters are considered safe and non-invasive, making them a popular choice for monitoring oxygen levels in patients.

However, pulse oximeters have limitations. They can be affected by factors such as motion, skin pigmentation, and certain medical conditions. For example, pulse oximeters may not provide accurate readings in patients with dark skin or those who are moving frequently. Additionally, pulse oximeters may not detect low oxygen levels in patients with certain medical conditions, such as carbon monoxide poisoning or methemoglobinemia.

In summary, pulssoksümeetri is a non-invasive medical device used to measure oxygen saturation and pulse rate. It is commonly used in clinical and home healthcare settings, but it has limitations and may not provide accurate readings in certain situations.
