[The determination of end-expiratory CO2 during resuscitation. Experience and results with the Normocap 200 (Fa. Datex) in preclinical resuscitation conditions].
Capnometers measure carbon dioxide (CO2) in inspired and expired air. Under physiological conditions end-tidal CO2 (peCO2) measurements closely reflect arterial pCO2 (paCO2). End-tidal CO2 concentration has been found to correlate with cardiac output in animal models and in clinical studies with cardiac arrest during cardiopulmonary resuscitation (CPR). ⋯ No statistical significance was found. In case of successful CPR there was a sudden rise in end-tidal CO2 up to 54 +/- 6 mmHg, indicating satisfactory spontaneous circulation. With capnometry it is possible to assess the efficacy of precordial compression during resuscitation and the return of spontaneous circulation in cardiopulmonary arrest.

Case Reports[CT findings of a cerebral air embolism as a consequence of an accidental subclavian catheter disconnection].
This report describes the definitive diagnosis of cerebral air embolism following accidental disconnection of a subclavian catheter by documentation of cranial CT's. We also discuss critically the pathophysiology of cerebral air embolism and its differentiation from "the bends". The necessity of recognising this entity is important in differential diagnosis. The pathophysiology of air embolism is discussed.
