Pressure Alarms Pressure Alarms Pressure Alarms Pressure Alarms
A front panel
LOW ALARM
control sets the low pressure limit. Available
alarm limits are 2 to 32 cmH
2
O (increments of 2 cmH
2
O). The alarm
sounds only after the low pressure setting has not been achieved for
two consecutive brea
ths.
Note
On the LP20, the audible alarm is double-pulsed for Low Pressure
alarm events.
A separate
HIGH ALARM/LIMIT
control permits the operator to set the
high pressure limit point. In Assist/Control or
SIMV
ventilation, the
alarm will sound whenever the high alarm setting is exceeded, but
the alarm automatically stops when the pressure drops to a level
below the limit. This control also sets the high pressure limit for
pressure limited ventilation. In this mode, inhalation is terminated
when the high pressure alarm set point is exceeded. The high pres-
sure alarm does not sound in the
PRESSURE LIMITED
mode unless
the pressure limit is exceeded by 10 cmH
2
O or more. Available set-
tings are 15 to 90 cmH
2
O in increments of 5 cmH

O.
Supplemental Oxygen Supplemental Oxygen Supplemental Oxygen Supplemental Oxygen
The ventilator includes provisions for the addition of prescribed sup-
plemental oxygen. The ventilator delivers up to 40% oxygen concen-
tration when the oxygen elbow and fitting is used. Concentrations
up to 100% are attainable when oxygen is delivered through the
inlet filter port (located on the rear panel), using the Oxygen Enrich-
ment Kit. Instructions for delivering supplemental oxygen are
included with these accessories.
PEEP PEEP PEEP PEEP
PEEP (Positive End Expiratory Pressure) is accomplished with the
ventilator by connecting an accessory valve to the patient circuit.
The ventilator is PEEP-compensated for up to +10 cmH
2
O. Complete
PEEP instructions are included with these accessories.
Humidification Humidification Humidification Humidification
When humidification is prescribed, several humidification devices
are compatible with the ventilator. Under normal extended use, an
active humidifier is often recommended. Nellcor Puritan Bennett can
supply a mounting bracket that is especially designed for the most
popular humidifiers. Connection information is supplied with the
mounting bracket.
A passive, in-line regenerative humidifier such as an artificial nose
is commonly used to conserve humidification during patient trans-
port or wheelchair use. It is intended for short-term use only. The
regenerative humidifier retains portions of the exhaled heat and
humidity, to aid in conditioning subsequent inhalations.
