<p>The nozzle (6) has a connection unit i.e. pipe (6-5), connected to an oxygen supplying unit (10) that supplies oxygen towards a flexible plastic bag (5). A sampling unit (6-6) samples exhaust gas released by a patient, and is connected to a determination device (14) for determining a respiratory frequency of the patient. The connection unit and the sampling unit extend from a base plate of the nozzle, where the base plate is in support against a seat (4-21) of a body (4) of an oxygen mask (2). A rib is in support against a wall of a collar of the mask body. An independent claim is also included for a high concentration oxygen mask with a body covering a nose and a mouth of a patient.</p> |
