Abstract: A resuscitation simulator includes a chest wall which moves back and forth along a compression path and a distance sensor as described for the invention which measures the optical path length between a transmitter and a receiver. The optical path length is determined by the position of the chest wall along the compression path. This enables the simple determination of the compression depth during reanimation training by measuring the optical path length and furnishes feedback to the person undergoing training in respect of the quality of the cardiac massages performed.

Abstract: A resuscitation simulator with an insufflation tube for artificial respiration by a helper and a Venturi tube joined to the insufflation aperture by a respiratory air-conducting connection. The Venturi tube has a first tube section, with the first inner cross-sectional area, and a second tube section, with a second inner cross-sectional area, with the second inner cross-sectional area smaller than the first inner cross-sectional area. The first pressure measurement is made on the first section of the tube, and a second pressure measurement is provided on the second section of the tube. A pressure measuring device is provided which is connected to the first measurement position and the second measurement position, with which a differential pressure between the first measurement point and the second measurement point can be determined. The pressure measuring device generates a pressure measurement signal from the measured value.
