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, wherein the first polyether block amide material comprises polyether segments and polyamide segments in a ratio of polyether to polyamide from about 60;
40 to about 40;
60, and the polyether segments comprise polyethyleneoxide; and
wherein a CO2 component of the respiratory gases passes the gas sampling tube without being absorbed in or adsorbed to the tube material to allow for an accurate reading at the gas monitor.

Abstract
A gas sampling line having a channel for conducting respiratory gases from a patient respiratory interface to a gas monitor, the gas sampling line comprising, i.a., a gas sampling tube comprised of a polyether block amide material, the polyether segments of which comprise polyethyleneoxide. Use of a tube comprised of a polyether block amide material, the polyether segments of which comprise polyethyleneoxide, for sampling of respiratory gases; and a method for sampling of respiratory gases, the method comprising conducting respiratory gases through such a tube. A gas analysis system for analyzing respiratory gases, comprising a gas sampling line as defined above and a gas monitor connectable to the gas sampling line.
