Functions & Features:

The HPA-900B ventilator is an electrically controlled pneumatic ventilator integrating such functions as time, volume cycling, pressure limit, etc. 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.

The automatic conversion for standby power while AC power outage, keep working not less than 1 hour.
