The proposed ventilator does not require a mechanical pump. It uses the pipeline pressure of the medical facility and regulates this pressure in order to deliver ventilations with certain Peak Inspiratory Pressure. No mechanical pump, would facilitate the production, reduces the costs, reduces the failures and maintenance requirements of the ventilator. The Ventilation Rate and I:E Ratio would be adjusted by a controller unit actuating the solenoid valves. The cylinder provides a "reservoir" of Air/O2 mixture for SIMV mode (i.e. if patient takes a spontaneous breath there is a ready-to-deliver mixture of Air/O2). A Hall Effect Sensor Position Measurement Device is attached to the cylinder and there is a magnet on the piston. Movement of the piston, changes the position of the magnet in relation to the Hall Effect Sensor Position Measurement Device. This allows said controller unit to determine the position of the piston, thus adjusting the tidal volume delivered to the patient by actuating the solenoid valves. Details of the controller unit and its connections to the element of the proposed ventilator are not illustrated at this stage so as not to obscure the main features.
