Capnography/ Multiparameter anaesthetic monitoring

Capnography is the measurement and evaluation of the levels of carbon dioxide in a patient’s exhaled breath. This is an important component of anaesthesia because it helps the anaesthetist evaluate the patient’s respiratory rate, and also the quality of the respiration. This allows a better interpretation of the patient’s anaesthetic depth and hence is valuable in preventing the occurrence of hypoxic episodes (low oxygen in the blood).
