WARNINGS!
• It is recommended to use the breathing tube and nasal cannula provided by BMC matching
with the device.
• The oxygen supply must comply with the local standards of medical oxygen.
• When the oxygen is used, please first open the device, start the ventilation, and then
connect oxygen; When shut down, please first disconnect the oxygen and then stop
ventilation to prevent the oxygen from accumulating in the device (when the device stops
running, but oxygen continues to be supplied, the oxygen sent into the tube will gather in
accessories of the device, which may lead to a fire hazard.
• Oxygen supports combustion. Device and oxygen source should be kept away from heat
sources, open fires, any oil or other combustible material. Do not smoke near device and
oxygen sources.
• The device and oxygen source must be at least two meters away from any source that can
emit sparks (such as: electrical device).
• It is prohibited to directly connect the manual mixed oxygen type (H-80M) with the oxygen
source which is not calibrated or of high pressure.
• The oxygen can only be transported through the oxygen inlet of the device. In order to
ensure oxygen to correctly flow into the device, the oxygen tube must be correctly installed
on the device.
• For the manual mixed oxygen type (H-80M), please do not connect oxygen whose flow is
higher than the set target flow to the device, because excessive oxygen will be discharged to
the surrounding environment.
• The concentration of oxygen transported to the patient will be affected by the airflow,
oxygen flow, patient interface and airway blockage. If the peak inspiratory flow of the patient
exceeds the output flow of the device, the FiO
2
inhaled by the patient will be diluted due to
inhaling the ambient air and lower than the value displayed on the device.
• When the device does not work, oxygen must be closed for fear of accumulating in the
device.
• The gas storage bag cannot be used as oxygen sources.
