The CCV-PA500 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. Its main features are as follows:

• Gas drive and electrical control, time-pressure switching and pressure limit control.
• A high-brightness LED digital display is used to present the control frequency, tidal
• volume, throughput, overall respiratory rate, spontaneous breathing frequency, etc.
• A highly sensitive and responsive pressure sensor and a flow sensor are used to
  measure, control and display the airway pressure and gas flow rate and the ventilator is
  equipped with automatic throughput compensation.
• In case of an abnormality to the ventilator or misoperation, the ventilator can raise a
  visual-audible alarm to automatically protect itself
