[Blood gas studies on the efficiency of the ventilator "Pulmomat" (author's transl)].
Efficiency of ventilation of Pulmomat has been examined in 48 patients under general anaesthesia and relaxation during normoventilation and hyperventilation of 15 and 30% degree. For criteria the acid-base status of arterial blood has been used. In normoventilation acid-base status remained unchanged within the normal range providing a regular control respectively correction of ventilationvolumes. There was no significant difference between results of 15 and 30% hyperventilation. In both situations arterial pCO-2 was reduced 15-20%. There was a tendency to acidosis in all kinds of ventilation presumably as a consequence of surgical effects. For security using the Pulmomat as respirator, a hyperventilation of 15% degree is recommanded in clinical use.
