EtCO2 Monitor and Sensors

An End-Tidal Carbon Dioxide (EtCO2) Monitor is a vital patient monitoring device that measures the concentration of carbon dioxide exhaled at the end of each breath. This provides a non-invasive, real-time assessment of a patient’s ventilation, metabolism, and pulmonary perfusion. The monitor works in conjunction with disposable or reusable sensors, which are typically integrated into breathing circuits or nasal cannulas to sample expired air. The resulting capnography waveform and numerical EtCO2 value offer immediate insight into respiratory status and the effectiveness of cardiopulmonary resuscitation (CPR).

Critical in operating rooms, intensive care units, and emergency medicine, EtCO2 monitoring is the standard of care for verifying endotracheal tube placement, monitoring sedated patients, and detecting hypoventilation or apnea early. Modern monitors are compact, feature intuitive displays, and include alarms for rapid response to changes in patient condition. The accompanying sensors are designed for single-patient use to ensure hygiene and accuracy. Together, this system is indispensable for enhancing patient safety, optimizing ventilation strategies, and improving outcomes in acute and critical care settings.
