Capnometry is a very sensitive and noninvasive monitoring method, which has full justification in emergency medicine. In out-of-hospital circumstances it take possible advantage specific assets of capnometry for quickly and secure identification of correctly endotracheal intubation, next as a certain sign of successfully CPR. In the course of interhospital intensive or emergency transports it is necessary comprehensive monitoring of patients. Capnometry has an important place here, especially in combination with pulse oximetry for monitoring adequate ventilation and for quickly recognize undesirable situation during transport, for example: ventilator failure, gas supply defect, ET tube oclusion, patient discord with ventilator, breathing circuit disconnection etc. Capnometry and capnography have become considerable improvement to monitoring of ventilated patients by activities and during transportations in conditions out-of-hospital emergency care. Therefore mobile units, which practise emergency medicine, should have capnometer with capnographic recording in equipment.
