Abstract
The gas flow, airway pressure, and gas composition are measured directly at the mouth, i. e., between the respirator and the patient, in the so-called “measuring head” (Fig. 1.1). This consists of a Fleisch pneumotachograph (PT) No.2 and two Teflon adapters, which provide a “soft” transition from the narrow endotracheal tube and the ventilator connector to the diameter of the PT. A catheter to measure the airway pressure (perpendicular to the flow) and the capillary for the mass spectrometer (tip in the center of the gas flow) are inserted into the Teflon adapter which is closer to the patient.
