'''Capnography''' is a non-invasive monitoring technique used in medicine to measure the levels of carbon dioxide (CO2) in exhaled breath. It provides information about the patient's ventilatory status, which can be useful in diagnosing and managing a variety of health conditions.

== Overview ==
Capnography works by analyzing the concentration of CO2 in a sample of exhaled air. The device used for this purpose is called a capnometer. The capnometer measures the amount of CO2 present at the end of an exhalation, which is known as the end-tidal CO2 (EtCO2) level. This level is a good indicator of the amount of CO2 in the blood, and thus of the effectiveness of ventilation and perfusion.

== Uses ==
Capnography is used in a variety of medical settings, including [[anesthesia]], [[intensive care]], [[emergency medicine]], and [[pulmonology]]. It can be used to monitor patients during surgery, to assess the severity of [[chronic obstructive pulmonary disease]] (COPD), and to guide treatment in conditions such as [[asthma]] and [[pneumonia]].

== Benefits ==
The main benefit of capnography is that it provides continuous, real-time monitoring of the patient's ventilatory status. This allows for early detection of changes in ventilation and perfusion, which can be critical in preventing serious complications. Capnography is also non-invasive, which means it can be used in a wide range of patients and settings.

== Limitations ==
While capnography is a valuable tool, it does have some limitations. For example, it may not provide accurate readings in patients with certain conditions, such as severe lung disease or shock. It also requires a good seal between the patient's face and the capnometer, which can be difficult to achieve in some cases.
