The invention relates to a respiratory arrangement (1) that includes: a control unit (3), a plurality of gas delivery hoses (4), and a patient-allocated or -related device (5), such as a facemask, wherein first end portions (4a) of respective hose face towards the control unit while second end portions (4b) of respective hose face towards said device. The control unit (3) inlcudes means for passing a gas flow, intended for inhalation, or passing a gas flow. intended for insufflation ("1") to said patient via a first hose (4c). An expiration valve (6), situated close to the patient-allocated or -related device is adapted to release a gas flow intended for expiration ("E") to the free surroundings and said expiration valve can be switched to one of two settings, via a second (4d) of said gas delivery hoses. A container (7) or gab containing a reserve volume (7') is adapted to generate a gas flow, which is intended for manual insufflation and which can be actuated by pressurising the container (7) or bag temporarily and for or during a short period of time. The reserve volume (7') of the pressurised container (7) or bag is delivered to the first hose (4c), via a valve arrangement (41), and said pressure is delivered to the second hose, via said valve arrangement (41) to cause the expiration valve (6) to take a closed state, associated with a manufal insufflation phase. |
