D- MANUAL CONTROLS AND CONNECTIONS

1- FRONT OF VENTILATOR

L / M I N ( L F L O W ) K N O B
A pneumatic needle valve which sets the inspiratory flow from 0- 15 lpm. The
Flow window displays the flow setting. It is accurate from 1 to 15 lpm.
P I P K N O B
A pneumatic needle valve which sets the pressure, which is applied to the
exhalation valve and to the internal diaphragm, actuated relief valve (D.A.R.V.)
and determines the PIP during assisted and controlled inspirations.
adjustable from 0 - 80 cmH
adjusted.
NOTE: To conserve gas, the PIP and PEEP controls should be
turned off (fully counter clockwise) when the CV-2i+ is not in use.
P E E P K N O B
(Positive End Expiratory Pressure)- A pneumatic needle valve which sets the PEEP or CPAP (Continuous Positive Airway
Pressure) level which is applied to the exhalation valve. It is adjustable from 0- 20 cmH
by observing the system pressure bar graph or with the PEEP/CPAP readout on the secondary alarm menu.
NOTE: The PIP should always be set higher than PEEP in order to achieve the PEEP setting.
NOTE: To conserve gas, the PIP and PEEP controls should be turned off (fully counter clockwise)
when the CV-2i+ is not in use.
A U D I B L E T O N E G E N E R A T O R
Located next to the BMD logo on the front of the unit, it emits the audible tones to indicate an alarm condition or keyboard
actuation. The tone for a standard alarm is rated at 90 dB.
WARNING: It should never be obstructed.
NOTE: Refer to Appendix D for all the beeper codes.

It flashes on and off in equal duration during any alarm providing full frontal visibility. When the unit is turned off or loses
power, it flashes for 3 minutes. This time may be less if the Crossvent was not powered on for at least 1 minute prior to
loss of power.
P O W E R O N / O F F S W I T C H
It is located on the front of the unit and is recessed in order to reduce inadvertent or unauthorized use. It controls the main
power to the electronics. If the battery is allowed to fall below 6 volts (well below the Low Battery alarm limit) with the unit
operating, the ventilator will turn off independent of this switch. If this occurs, this switch must be turned to OFF before
the ventilator will operate again, regardless of power source.
