The Ventilation Control Module VCM has been developed especially for producing a negative pressure at a respiratory rhythm as required for operating an isolated perfused rabbits, rats, guinea-pigs, or mouse lung. The module operates with a positive pressure. The negative pressure required for ventilation is generated by means of a venturi nozzle which is fitted externally. When used with a restrictor nozzle the module can also be employed for positive pressure ventilation during the preparation phase of the lung, a very convenient facility. The VCM module works independently; it requires neither a vacuum nor a compressed air supply. The module consists of an electronic and a pneumatic section. A low-noise pump stores the compressed air in a small reservoir where it is stabilized electronically. The air stream which appears at the outlet connection (TO VENTILATION HEAD) passes through adjustable valves. The air is controlled electronically according to the selected respiration rate (RATE) and the selected inspiration cycle (INSP. CYCLE%). In addition one (or several) deep breaths (DEEP INSPIRATION) can be triggered by pressing a button. The output therefore consists of a rhythmically modulated air stream at a positive pressure. By connecting it to a suitable nozzle a rhythmically modulated pressure of the desired magnitude can be produced.
