Abstract

A tracheal tube (1) for giving artificial respiration to a patient comprises a balloon cuff (7) for sealing. The respiration gas is blown in by producing excess pressure, and taken off by producing underpressure, in a respiration tube (11) having a relatively small diameter. To monitor the intratracheal pressure in the closed respiratory system, a pressure measuring cannula (14) is provided, so that a respiration within the desired intratracheal pressure range can be ensured, through an electronic control device (29), by a respirator (13) operating to blow in an exhaust respiratory gas.
