A modular monitoring and ventilation system includes a standalone monitor unit for monitoring patient-related parameters that are indicative of the physiological status of a patient, which receives at least one signal indicative of such a patient-related parameter from at least one sensor and that displays information related to that signal on a display, and a standalone, portable pneumatic unit for ventilatory treatment of a patient by supplying breathing gas to the patient. The monitor unit and the pneumatic unit are able to placed in a paired state in which they are communicatively connected to each other for information exchange, and in which those units cooperate to provide ventilatory treatment to the patient, with operation of the portable pneumatic unit being controlled based on the signal that is indicative of the monitored patient-related parameter, received by the monitor unit from the at least one sensor.
