Capnography During Critical Illness.

Chest. 2015 Oct 8;

Authors: Nassar BS, Schmidt GA

Capnography has made steady inroads in the ICU, being increasingly used for all mechanically ventilated patients. There is growing recognition that capnography is rich in information about lung and circulatory physiology, providing insight into many diseases and treatments. These include conditions of impaired matching of ventilation and perfusion, such as pulmonary embolism and obstructive lung diseases; circulatory questions such as the adequacy of chest compressions during cardiac arrest or fluid-responsiveness in patients in shock; and the safety of procedural sedation. In this review, we emphasize analysis of the entire capnographic waveform as a way to glean additional useful information. At the same time, we discuss important limitations of capnography, especially when it is considered as a surrogate for the PaCO2.
