Final answer:
The standard for intraoperative monitoring of oxygenation levels for all age groups of surgical patients is typically done using a device called a pulse oximeter, which measures the percent saturation of oxygen in the blood.
Step-by-step explanation:
The standard for intraoperative monitoring of oxygenation levels for all age groups of surgical patients is typically done using a device called a pulse oximeter, which measures the percent saturation of oxygen in the blood.
The device works by emitting two different wavelengths of light (red and infrared) through a thin part of the body, such as the fingertip, and measuring the light that is absorbed by the oxygenated hemoglobin in the blood.
Normal pulse oximeter readings range from 95-100 percent, indicating sufficient oxygenation levels.
