Part Description
E1
Airway pressure gauge 1
The gauge is used to indicate the patient's airway
pressure.
A slight difference between the readings of the airway
pressure gauge and the electronic readings is normal.
Contact the after-sales service department of Mindray if
the difference exceeds 15%
E2
Manual/auto switch
The manual/auto switch is used to switch between
mechanical ventilation and manual ventilation.
E4
Handrail
The handrail is an encircling metal bar used for moving
the machine.
E5
Work surface
The stainless steel work surface bears maximum force
of 30 kgf (66 lbf).
E6
APL valve 1
The APL valve is a rotary regulator for setting the
pressure limit of the breathing system during manual
ventilation. The scales on the APL valve indicate
approximate pressure. The APL valve is set to the SP
position during spontaneous breathing. If necessary, lift
the APL valve to release pressure quickly. At the flow
of 3 L/min, the pressure of the APL valve under a dry
or wet condition must be greater than 1 cmH2O and
less than 3 cmH2O. At the flow of 30 L/min, the
pressure of the APL valve under a dry or wet condition
must be greater than 1 cmH2O and less than 5 cmH2O.
