In a breathing appts., a measurement tube (8) is in the flow path of the exhaled air linked to a number of monitors. A carrier (20) has at least two barriers (21,22,24,25,26) against moisture and bacteria as filters and/or membranes. The carrier (20) is between the tube (8) and the monitoring assembly (9) which contains a pressure monitor (10), ultrasonic flow meter (11), carbon dioxide meter (12), oxygen sensor (13) and a temp. monitor (14). |
