[Artifical ventilation and spontaneous respiration under CO2-control (author's transl)].

In patients undergoing anaesthesia with controlled respiration the respiratory minutevolume required is not predictable! A "Compact-Respiratory-Monitor" enables the anaesthesiologist to observe simultaneously alveolar respiratory minute volume and end-tidal CO2-concentration as well. During anaesthetics with controlled respiration both values should be kept in parallel, while the end-tidal CO2-concentration has to be stabilized around 4vol% by adjusting the respiratory minute-volume to an adaequate level. Spontaneous changes of these parameters indicate disturbances due to ventilation/perfusion-relationship. This instrument was created for use in daily routine work. Over- and underventilation can be avoided by the use of this instrument.
