Capnography is used for assessment of
Capnography is the method of determining CO2 levels in exhaled gases (PACO2) but NOT blood.It is the ideal confirmatory method of endotracheal intubation(VENTILATION OF LUNG AFTER INTUBATION) Aeral blood gas analysis is used to measure CO2 levels in Blood (PaCO2) Pulse oxymetry is used to measure oxygen saturation of blood and hea rate.
Oxygen saturation of blood
Amount of CO2 transpoed in blood
Ventilation of lung after intubation
Myocardial perfusion
Preoperative assessment and monitoring in anaesthesia
