A ventilator for respiratory treatment comprises gas delivery means (16) and regulating means (14) arranged to control said gas delivery means to deliver gas to a patient (8) according to prescribed parameter values to obtain sufficient ventilation of the patient. Means (10) are provided for sensing respiration efforts of the patient and to control said regulating means to adapt an operation cycle of the gas delivery means to sensed respiration efforts of the patient. The regulating means control the gas delivery means 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 sensing means the regulating means are arranged to control the gas delivery means to deliver gas to the patient according to the above prescribed parameter values. <IMAGE> |
