A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16). |

1. A ventilation system comprising:
a gas supply device; a tube arrangement, wherein the tube arrangement has a patient port for connection to a patient in order to send gas from the gas supply device to the patient and in order to remove gas exhaled by the patient; a flow control device for controlling the gas flow from the gas supply device to the patient port and for controlling the gas flow away from the patient port); a sensor unit, which is arranged in the tube arrangement and is set up to detect parameters of the gas supplied to the patient and exhaled by the patient; a control and regulation unit for controlling the gas supply device and the flow control device, which control and regulation unit is connected to the gas supply device, to the flow control device, and to the sensor unit,wherein:
the control and regulation unit is designed to ensure that in a first mode of operation, the flow control device is actuated during an expiration phase such that the pressure of the gas exhaled by the patient at the patient port is described by a first curve, and the flow control device is actuated during an inspiration phase such that the pressure of the gas supplied to the patient at the patient port is described by a second curve, wherein the expiration phase and the inspiration phase follow each other in a continuously alternating manner; the control and regulation unit is designed to have a second mode of operation; the control and regulation unit is designed such that in the second mode of operation the flow control device is actuated during the expiration phase such that the pressure of the gas exhaled by the patient at the patient port is described by a third curve, which is increased compared to the first curve, at least during a section of the expiration phase; and the flow control device is actuated during an inspiration phase such that the pressure of the gas supplied to the patient at the patient port is described at least during a section of the inspiration phase by a fourth curve, which is reduced compared to the second curve; and a switchover device for switching over the control and regulation unit between the first and second modes of operation. |
