In the present issue of Critical Care Grmec and colleagues compared the initial and subsequent PETCO2 in patients who had cardiac arrest precipitated by either asphyxia or ventricular arrhythmia. A much higher PETCO2 was found immediately after intubation in instances of asphyxial arrest. Yet after 1 min of closed-chest resuscitation both groups had essentially the same PETCO2 with higher levels in patients who eventually regained spontaneous circulation. The Grmec and colleagues study serves to remind us that capnography can be used during cardiac resuscitation to assess the mechanism of arrest and to help optimize the forward blood flow generated by external means.
