Disclosed is a trigger-type high frequency jet ventilator for cardiopulmonary resuscitation, said ventilator comprising a control unit and a jet ventilation device. The jet ventilation device is connected to an artificial airway via an air pipe, and the control unit is connected to a sensing unit used for sensing thorax rising and falling or a breathing airflow, or to an artificial cardiopulmonary resuscitation machine. The control unit receives a sensing signal sent by the sensing unit or a pressing signal from the artificial cardiopulmonary resuscitation machine, and then issues a jet start command to the jet ventilation device at a thorax pressing end point. Also disclosed is a sensing and regulating ventilator for cardiopulmonary resuscitation, said ventilator comprising a sensing unit, a control module and a ventilation device. The sensing and regulating ventilator is connected to an artificial airway or a natural human airway via an air pipe. The sensing unit is used for sensing a thorax rising and falling state during cardiopulmonary resuscitation, and issuing a sensing signal to the control module. The control module receives the sensing signal sent by the sensing unit, and then issues a command to the ventilation device. The ventilators ventilate at a patient cardiopulmonary resuscitation thorax rebound phase, ensure uninterrupted pressing during ventilation and asynchronous pressing during breathing, and effectively improve a ventilation effect during cardiopulmonary resuscitation. The pressing of this kind of ventilation on pulmonary blood vessels encourages pulmonary blood to flow back to the heart, increases the amount of blood returning to the heart, and promotes blood circulation under chest pressing.Linvention concerne un appareil de ventilation à jet haute fréquence de type à gâchette pour la réanimation cardio-pulmonaire, ledit appareil de ventilation comprenant une unité de commande et un dispositif de ventilation à jet.
