GAS SAMPLING LINE
First Claim
1. A gas sampling line having a channel for conducting respiratory gases from a patient respiratory interface to a gas monitor, the gas sampling line comprisinga patient respiratory interface connector adapted to couple the gas sampling line to a patient respiratory interface;
- a gas sampling tube adapted to conduct respiratory gases; and
a gas monitor connector adapted to couple the gas sampling line to a gas monitor,wherein the gas sampling tube is comprised of a first polyether block amide material, the polyether segments of which comprise polyethyleneoxide.
