An intubation tube contains both a sampling connector (2) for a gas analyzer and a spirometer (18). Spirometer (18) and sampling connector (2) are manufactured so that, in operation, they make up a single unit which is linked via outflow tubes 6 and 7 to pressure and/or flow measuring elements (12, 13) as well as via a sampling tube (9) to a gas analyzer (10). A microprocessor adjusts the flow rate in accordance with the composition of the gas as determined by the gas analyzer. |
