pulzusoxiimetriával

Pulzusoximetria is a non-invasive medical procedure used to measure a person's oxygen saturation level in the blood. It is also commonly used to measure pulse rate. The device, called a pulse oximeter, is typically a small clip that is attached to a finger, toe, or earlobe. It works by emitting two beams of light, one red and one infrared, through the tissue. The amount of light that is absorbed by hemoglobin, the protein in red blood cells that carries oxygen, is measured. Hemoglobin that is saturated with oxygen absorbs infrared light differently than hemoglobin that is not saturated with oxygen. By comparing the absorption of the two light beams, the pulse oximeter can calculate the percentage of hemoglobin that is carrying oxygen. This percentage is known as the oxygen saturation, or SpO2. A normal SpO2 reading is typically between 95% and 100%. Lower readings may indicate hypoxemia, a condition where there is insufficient oxygen in the blood. Pulse oximetry is a valuable tool for monitoring patients with respiratory or cardiac conditions, during surgery, or in critical care settings. It provides a quick and easy way to assess oxygenation status without the need for blood draws.
