These clinical-grade Phasein ISA sidestream anesthetic gas (AG) analyzer modules are engineered to deliver comprehensive breath-by-breath capnography and multi-gas analysis in acute surgical suites. The ISA AX+ platform provides real-time tracking and automatic identification for carbon dioxide, nitrous oxide, and five distinct anesthetic agents. For advanced physiological profiling, the ISA OR+ system integrates an ultra-precise, maintenance-free paramagnetic oxygen sensor to continuously monitor inspired and expired fractional oxygen levels. Both high-performance systems utilize advanced Nomoline sampling technology to actively strip moisture from incoming gas feeds without regular water trap maintenance, ensuring stable waveforms during continuous ventilation.
