NPB-75: A portable quantitative microstream capnometer.

Abstract A portable quantitative microstream capnometer (NPB-75) was tested in intubated children. The end-tidal CO 2 values measured by this device showed good agreement with concomitantly measured values of a stationary mainstream capnometer (N-6000). This lightweight device, with a 4-hour battery life, graphic capnogram display, and audiovisual alarms is well suited for the prehospital setting. (Am J Emerg Med 2001;19:208-210.
