Abstract
A ventilator for respirator treatment includes a gas delivery unit and a regulating unit arranged to control the gas delivery unit to deliver gas to a patient according to prescribed parameter values to obtain sufficient ventilation of the patient. Sensors are provided for sensing respiration efforts of the patient and to control the regulating unit to adapt an operation cycle of the gas delivery unit to sensed respiration efforts of the patient. The regulating unit controls the gas delivery unit also to deliver a pressure or volume support to the respiration of the patient to a predetermined resulting total pressure or volume level. If an apnea exceeding a predetermined length of time is detected by the sensor, the regulating unit controls the gas delivery unit to deliver gas to the patient according to the aforementioned prescribed parameter.
