The MDPro 662531 is a specialized airway adapter designed for use with the MicroCap 9 handheld capnograph system. This component serves as the critical interface between the patient's breathing circuit and the CO2 sampling line, allowing for precise side-stream capnography monitoring. Engineered for intubated patients, it ensures a secure, leak-free connection to maintain the integrity of real-time EtCO2 waveforms and respiratory data. Its lightweight construction and universal fit make it an essential accessory for anesthesia and intensive care environments.
