Capnography during CPR in a patient in cardiac arrest. The attenuated capnography trace is seen when pulmonary ventilation is occurring. A flat capnograph trace should be assumed to be because of oesophageal intubation (or rarely airway blockage) until this has been actively excluded (with permission of Dr S. Chapman and Prof. J. Benger).
