The BT-S500 ventilator is an electrically controlled pneumatic ventilator integrating such functions as time, volume cycling, pressure limit, etc. It is mainly intended for providing ventilation support to a critically ill patient during the life threatening phase and ensuring the going-through of the dangerous period by the patient and smooth treatment of primary diseases for recovery. Also it provides an alternation in case of irreversible lesions in respiratory muscles or irreversible damage to upper airway to maintain the respiratory function of the patient, and also provides ventilation assistance for the patient during the recovery from a disease or operation.
