The present invention relates to a ventilating system adapted to supply breathing gas to a patient and exhaust used gas therefrom. The ventilating system comprises a main ventilating device for supplying breathing gas to a patient, detecting device for detecting malfunction of the main ventilating device, and an auxiliary ventilating device. The auxiliary ventilating device includes a hollow tube installed along a connector of the main ventilating device and an auxiliary breathing gas supply device connected to the hollow tube. When the detecting device detects malfunction of the main ventilating device, the auxiliary ventilating device automatically actuates to supply breathing gas to the patient.
