The CAPNOX is a compact, mobile capnograph for ambulances, day-surgeries and clinical environments. The unit continuously monitors the expiratory carbon dioxide concentration, the respiration rate, the arterial oxygen saturation and the pulse rate of a patient. The CO2 values can be shown in mmHg, kPa or in Vol%. Because of the sidestream system, the CAPNOX can be used on intubated- as well as on non-intubated patients. Compared to any other capnograph, the CAPNOX is a very lightweight solution. The high-end pneumatics work quietly, without disturbing patient or user.
