This nasal prong cannula is intended for use with the Spacelabs 92516, 92517 capnography modules and the 92518 multigas module. It’s a standard adult size that uses a nasal prong plus oral scoop system that rests on the patient face, secured behind the ears which allows exhaled nasal gases to be collected through the sampling line and into the capnography module for analysis. It includes an integrated O2 line and extra long 3 meter sampling line. It has a standard luer lock port at the end of the sampling line to connect to a NomoLine water/bacteria filter. Note: water/bacteria filter is required and no longer available from Spacelabs. See the new high and low humidity single-patient use NomoLine supplies as these are intended to replace this part.
