Measuring oxygen levels, also known as pulse oximetry, is a crucial procedure in medical settings to assess the oxygen saturation of a patient’s blood. Pulse oximetry involves clipping a small device, called a pulse oximeter, onto a finger, earlobe, or toe. The device emits light waves that pass through the blood vessels and are absorbed by hemoglobin, the oxygen-carrying protein in red blood cells. Based on the amount of light absorbed, the pulse oximeter calculates the oxygen saturation percentage, providing valuable information about the patient’s respiratory status.
Maintaining healthy oxygen levels is essential for overall well-being. Adequate oxygen levels ensure proper functioning of vital organs and tissues, preventing complications and promoting optimal health. Conversely, low oxygen levels, known as hypoxemia, can lead to tissue damage, organ dysfunction, and even life-threatening conditions. Therefore, monitoring oxygen levels is a critical aspect of medical care, enabling prompt intervention when necessary.
