Pressure Limit
(LP10 Only)
LP6 Plus and LP10 User’s Manual
The pressure limit valve is a mechanical pressure valve located behind the
Patient Air tube. The ventilator’s microprocessor does not control this
valve.
Note Pressure limit control ventilation is intended for use with uncuffed
tracheostomy tubes, or in other circuit configurations which ensure
an intentional airway leak.
The Pressure Limit control limits the pressure in the airway during inspiration.
Inspiration continues after reaching the preset high pressure level
and lasts until the Inspiratory Time expires.
Use the following instructions to activate and adjust the Pressure Limit
Control.
To set the Pressure Limit level on the LP10:
1. Disconnect the patient from the ventilator. Provide another means of
ventilation.
2. Turn the Pressure Limit Control counterclockwise until it stops.
Note The outside ring of the knob must be pushed in before the center adjustment
knob can be moved.
3. Set all controls to the prescribed settings.
4. Block the Exhalation manifold at the port that connects to the patient.
Warning Wash hands thoroughly. Do not introduce germs or contaminants
into the patient circuit while performing this task.
5. Watch the needle on the Patient Pressure Meter. Note the highest
pressure achieved during a machine-delivered breath. This should be a
very low pressure reading.
6. Turn the Pressure Limit Control clockwise in small increments until
the meter needle reaches, but does not exceed, the pressure value prescribed
by the physician.
