What is Capnography? ETCO2 Monitoring in Urdu Hindi by MWM Medical br br Capnography Monitoring Respiratory Functionbr br br Capnography is a medical diagnostic tool that measures the concentration of carbon dioxide (CO2) in a patient's exhaled breath. It is commonly used in anesthesia and intensive care settings to monitor a patient's respiratory function and to detect any potential problems, such as airway obstruction or respiratory arrest. Capnography can also be used to confirm proper placement of a breathing tube or to detect leaks in the breathing circuit. The measurement is typically displayed as a graph, called a capnogram, which shows the concentration of CO2 over time. Capnography is a noninvasive and safe method for monitoring respiratory function in real-time, and can help to ensure that the patient is receiving adequate oxygenation and ventilation.
