Capnogram

A capnogram is a graphical representation of the concentration of carbon dioxide (CO2) in the exhaled breath over time. It is commonly used in clinical settings to assess the adequacy of ventilation and to monitor respiratory function. The capnogram is typically recorded using a capnograph, a device that measures the CO2 concentration in exhaled air.

The capnogram provides valuable information about the patient's respiratory status. A normal capnogram shows a rapid rise in CO2 concentration during exhalation, followed by a rapid decline as the patient inhales. This pattern indicates adequate ventilation and normal respiratory function. In contrast, an abnormal capnogram may indicate conditions such as hypoventilation, hyperventilation, or respiratory failure.

Capnograms are particularly useful in monitoring patients during anesthesia, as they can help detect and manage respiratory complications. They are also used in intensive care units to monitor patients with respiratory distress or other conditions that affect ventilation. The capnogram is a simple and non-invasive tool that provides important information about the patient's respiratory status.
