Ventilator

A system comprising:

• a ventilator for a mechanical ventilation of a patient, the ventilator comprising:
• an exhalation valve;
• an inhalation valve;
• an inspiratory pressure sensor;
• an expiratory pressure sensor;
• a control unit;
• a ventilator data interface configured to provide predefined values to the control unit;
• and a connection system with an inhalation line for feeding breathing gases to the patient and with an exhalation line for removing breathing gases from the patient, wherein:
• the inspiratory pressure sensor is arranged in or at the inhalation line of the connection system;
• the inspiratory pressure sensor is configured to detect an inhalation pressure and to provide the inhalation pressure measured value for the control unit;
• the expiratory pressure sensor is configured to provide the expiratory pressure measured value for the control unit;
• the control unit is configured to control the inhalation valve taking into account the inhalation pressure measured value in order to provide an inspiratory pressure level via the inhalation line of the connection system for the patient;
• the control unit is configured to control the exhalation valve taking the expiratory pressure measured values into consideration in order to provide an expiratory pressure level for the patient via the exhalation line of the connection system;
• the control unit is configured to control the inhalation valve and the exhalation valve such as to raise the inspiratory pressure level from a first pressure level to a predefined second pressure level and to maintain the inspiratory pressure level for a first predefined time period;
• the control unit is configured to control the inhalation valve and the exhalation valve such as to raise the second pressure level to a predefined third pressure level and to maintain the third pressure level for a second predefined time period;
• and the control unit is configured to take predefined values into consideration during the control of the pressure levels and during the control of the time periods;
• a measuring device arranged in or at the system or a measuring device associated with the system, wherein the measuring device is associated with a measuring device control unit for a measurement-based detection of a data set of invasive and/or non-invasive blood pressure measured values of the patient and for providing the data set of blood pressure measured values PBP by means of a measuring device data interface, wherein the ventilator data interface and the measuring device data interface are formed and intended for providing and implementing a wired and/or wireless communication with one another, and the communication between the ventilator and the measuring device provides for a coordinated operation of the measuring device and ventilator with a synchronization in time of the control of the inspiratory pressure level with the measurement-based detection of the data set of invasive and/or non-invasive blood pressure measured values.
