ICU ventilator,medical ventilator,emergency ventilator Feature: A. Medical staffs can choose one among the three modes such as constant-time, constant-volume and constant-pressure according to the patients' condition or can circularly choose anyone among the three modes. B. Multiform respiratory modes can be chosen under the three switching modes, which can guarantee for clinical fine respiratory treatment. C. Comprehensive setting and display of alarm value. D. Configured with exact adjustment system for respiratory gas-oxygen concentration, calculagraph and constant temperature humidifier for inspiration gas. E. Perfect computerized monitor for ventilating parameters and display for presetting number.
