normally within the input pressure range of 280kPa~600kPa. It shall not cause any hazard when
the pressure of the air inlet is up to 1000kPa. When the gas source pressure is 280kPa, the
average gas flow measured at the high-pressure gas input port of the ventilator shall not exceed
60L/min (over 10s time-weighted average); and the instantaneous flow shall not exceed
200L/min (within 3s).
4.2 Alarm of abnormal gas-source supply
The ventilator shall have an alarm function of abnormal gas-source supply. When the gas-
source supply pressure is too low to maintain the normal operation of the ventilator, the
ventilator shall be able to generate a high-priority alarm or a continuous audible alarm in
accordance with YY 0709; and the audible alarm signal shall at least last 120s.
4.3 One gas missing in the air-oxygen mixing system
In addition to the air-oxygen mixing system mixed with the atmosphere, if a gas is missing in
the air-oxygen mixing system, the ventilator shall be able to automatically switch to make the
remaining gas continue working; and at the same time, it shall generate an alarm signal of at
least low priority in accordance with YY 0709.
5 Power Supply
5.1 Alarm on the abnormality of grid power supply
The ventilator that is powered only by the grid power supply shall have the function of alarming
the abnormality of grid power supply. When the voltage of the grid power is too low to maintain
the normal operation of the ventilator, a high-priority alarm or a continuous audible alarm in
accordance with YY 0709 shall be activated; and the audible alarm signal shall last at least 120s.
5.2 DC power supply
In addition to the grid power supply, if the ventilator is additionally equipped with a DC power
supply (internal power supply or external DC power supply), and can automatically switch to
DC power supply when the grid power supply is abnormal to maintain its normal operation,
then when the grid power supply is abnormal, the alarm on the abnormality of grid power supply
shall not be activated. For the conversion of such power supply, it shall comply with the
provisions of the information prompt signal or low-priority alarm signal specified in YY 0709.
The ventilator that is powered by DC power supply should activate a medium-priority alarm in
accordance with YY 0709 when the battery is low; and should activate a high-priority alarm in
accordance with YY 0709 before all power is lost.
If the ventilator is equipped with a DC power supply, a method for the operator to determine
the status of the DC power supply shall be provided.
5.3 Prevent mis-operation of the power switch
A method to prevent mis-operation of the power switch shall be provided.
5.4 Power cord
If the ventilator does not have a backup power supply, its equipped grid power cord shall be a
non-detachable power cord; or measures shall be provided to prevent the grid power cord from
accidentally falling off the ventilator.
6 Mechanical Strength
The ventilator that can be used for out-of-hospital transport shall be able to withstand the stress
caused by rough operation during working; and the ventilator shall continue to work during and
after the vibration impact test according to 21.6a), 21.6b) and 21.6aa) of YY 0600.3-2007.
7 Waterproof
The waterproof rating of ventilators that can be used for out-of-hospital transport shall be IPX4.
8 Fireproof
In normal or single fault conditions, combustible materials shall not be in both of the following
conditions at the same time:
--- the material temperature reaches the minimum ignition temperature;
--- the presence of oxidizing agents.
9 Cleaning, Disinfection or Sterilization
Accessories and components in the ventilator breathing system that may be contaminated with
rebreathing gases shall be removable for cleaning, disinfection, or sterilization.
If the label indicates that the product is sterile, the product should be sterilized by appropriate
and effective methods in accordance with the relevant descriptions in GB 18278.1, GB 18279.1,
GB 18280.1 and GB 18281.
Packaging systems without passing through the sterilized equipment shall maintain product
cleanliness prior to sterilization, use; and minimize the risk of bacterial contamination.
