A Breathing Apparatus and a Method therein

摘要

The disclosure relates to detection of leakage in a sampling line of a breathing apparatus, which comprises a gas monitor (102) for monitoring at least one gas, including a pump (106) for controlling a sidestream flow to the gas monitor (102), connectable to a mainstream of a patient circuit (108); a sampling line (110) for the sidestream flow, having a first end (112) being connectable to the gas monitor (102) and a second end (114) being connectable to the patient circuit (108); and at least a first pressure sensor (118) for measuring a pressure at the sidestream gas monitor (102), in operation providing a first pressure signal for the pressure; and a processing unit (120) operative to determine if a leakage of the sampling line (110) is occurring based on at least the first pressure signal.
