Electrical Interference
Electrical Interference
LP6 Plus and LP10 Clinician’s Manual
Caution
Warning
Your ventilator is an electronic instrument. Any electronic instrument is subject to electrical interference. Electrical interference in
excess of 10 V/m may keep your ventilator from working properly.
Television sets, cordless or cellular telephones, microwave ovens, air conditioners, food processors, and other appliances can be sources of electrical interference. To avoid electrical interference between your ventilator
and these appliances, you must follow these instructions:
• Never place your ventilator near these appliances.
• Never plug the ventilator into the same A.C. electrical outlet as
these appliances, nor into electrical outlets on the same circuit as
these appliances.
• Never place the cables from ventilator accessories near these appli-
ances.
Electrical interference may keep your ventilator from working
properly, which may create a hazard to the patient.
Page 4
Note The ventilator is exempt under Section 15.801 (c)(5) of the no interfer-
ence regulations adopted by the FCC. If television interference does
occur, contact Technical Services at Puritan Bennett, Inc. or a television
repair technician for suggestions. Or, move the television to an A.C.
electrical outlet that does not allow interference.
General Description
The Puritan Bennett LP6 Plus and LP10 Volume Ventilators are intended
for use in a non-acute care institution or transport, on pediatric and adult
patients. It is to be operated in accordance with the product labeling contained in this instruction manual.
The LP6 Plus and LP10 Volume Ventilators are microprocessor-controlled
volume ventilators. They provide continuous respiratory support for patients
with respiratory insufficiencies in a skilled nursing facility or hospital, or
during transport. Because of the compact design and light weight, the units
are highly portable.
The ventilators offer a wide range of delivery volumes, inspiratory times, and
breathing rates. The physician or the respiratory therapist can set the appropriate ventilation via the controls located in the recessed front panel. The
magnetically latched door panel and the control knobs are designed to prevent tampering and accidental resetting.
Audible and visual alarms quickly identify problems. See pages 6 through 9
for a complete discussion of these alarms.

Warnings
All alarms indicate a potential risk to patient safety. When an
alarm sounds, provide immediate attention, care, and support to
the patient as dictated by the situation.
Any device is subject to unpredictable failures. To ensure patient
safety, an appropriately trained caregiver should monitor ventilation. If the patient’s condition warrants the use of an independent secondary alarm, remote alarm, or another external
monitoring device, the physician should prescribe it. The physician should also determine to what level the patient may require
an alternate means of ventilation.
Certain types of ventilators, including the LP Series, have a Low
Inspiratory Pressure Alarm. The purpose of this alarm is to alert
the clinician or caregiver when the pre-set alarm parameters are
violated. As set forth in the LP Series Clinician’s and User’s
Manuals, a number of environmental factors and circuit accessories/components can affect the pressure in the breathing circuit.
These factors may prevent circuit pressure from violating the
low-pressure parameters, even in the event of a circuit being disconnected from the patient. Therefore, it is important for the clinician to consider and monitor these environmental factors when
establishing pressure alarm parameters. Depending on the specific clinical situation (e.g., risk of disconnect perceived as high,
patient is ventilator dependent) a secondary means of monitoring
ventilation (e.g., pulse oximetry) should be considered.
Responding to Alarms
The ventilator has visual and audible alarms. The audible alarm is usually a pulsating tone. Both the ventilator and the remote alarm emit
these tones. Flashing or steady light(s) on the ventilator indicate the
source of the problem.
A Pulsating Audible Alarm and Flashing Light(s):
The Low Power, High Pressure, Setting Error, and Power Switchover
alarms all use this type of alert signal.

Note In Assist/Control and SIMV modes, the High Pressure Alarm sounds
Responding to Alarms
A Steady Audible Alarm and Steady Lights:
This combination indicates a detected microprocessor error in the ventilator.
Single Reminder Tone:
A single tone sounds every five minutes when the internal battery powers the ventilator.
whenever the air pressure exceeds the selected high pressure limit. In the
Pressure Cycle mode, however, the High Pressure Alarm sounds only
when the air pressure exceeds the selected high pressure limit by 10
cmH2O/hPa.
When an alarm sounds:
First, attend to the patient immediately. Then, check the flashing or
steady light(s) on the ventilator to identify the source of the problem.
You may press the Alarm Silence/Reset button to silence the alarm. This
turns off the signal for one minute. If the alarm condition is corrected
during that minute, the alarm light will turn off.
A microprocessor error cannot be silenced. You cannot silence an alarm
before it occurs.
Note If a High Pressure, or Setting Error alarm condition is corrected before
you press Alarm Silence/Reset, the audible alarm will stop but the light
will continue to flash. Press Alarm Silence/Reset to turn off the light.
If a Low Pressure/Apnea, Low Power or Power Switchover alarm condition is corrected before you press Alarm Silence/Reset, both the audible
and visual alarms will continue. You must press Alarm Silence/Reset to
turn off the audible alarm and the light.
Warning
If alarms continue to sound, provide another means of ventilation and contact your homecare dealer.

patient’s breathing effort. When the patient’s effort reaches the setting, the Breathing Effort light turns on and the ventilator delivers a
breath. Push in the control knob to change the setting.
6. High Alarm/Limit: This sets the point at which the High Pressure
alarm will sound. If the pressure exceeds this limit, the High Pressure alarm sounds (except in the Pressure Cycle mode). Delivery of
this breath stops after the pressure reaches this limit. The audible
alarm is automatically silenced if the following breath does not
exceed the setting.
Often, when the high alarm sounds, the patient circuit has an
obstruction. Clearing the circuit will stop the alarm.
7. Low Alarm: This establishes the pressure which must be exceeded
with “controlled” or "assisted" breath. The alarm sounds only when
two consecutive breaths do not reach the selected limit, or if the
limit is reached but the pressure fails to return to a level below the
limit. Normally, this setting is just below the pressure you need for
proper ventilation.
If this alarm sounds, look for a leak in the patient circuit. A leak or
disconnection of the circuit is often the cause for the alarm.
Note Some circuit components will prevent a Low Pressure alarm by keeping
the pressure in the circuit above the alarm limit. Examples of these components include hydrated heat and moisture exchangers (HMEs) and tracheostomy tubes. If the patient circuit is disconnected from the patient,
but still connected to these components, a Low Pressure alarm may not
sound.
Where such disconnections from a ventilator-dependent patient are possible, you must set the Low Pressure alarm to a level that permits an
alarm to sound. To do this, simulate the disconnection; if a Low Pressure/Apnea alarm does not sound after two breath cycles, increase the
alarm limit until an alarm sounds.
8. Pressure Limit (LP10 Only): This limits the maximum pressure
developed for each breath. For use with Assist/Control or SIMV
modes only; use in other modes may not allow effective ventilation.
See Operating Modes section, below, for details.

Operating Modes
Assist/Control In this mode, if the breathing effort is strong enough to trigger the
Breathing Effort light, the ventilator assists breathing. The ventilator
then delivers the selected prescribed volume of air. If the patient makes
no effort to breathe and, thus, fails to activate the Breathing Effort light,
the ventilator takes control. It delivers breaths at the selected rate.
Breath Rate set at 1 - 5 BPM
If the patient does not start a breath on his/her own for 10 seconds, the
Apnea alarm sounds and alerts the caregiver. Meanwhile, the ventilator
delivers breaths at 10 BPM at the selected volume.
Breath Rate set at 6 BPM or more
No alarms sound if the patient fails to start a breath. The ventilator continues to deliver breaths at the selected rate and volume.

Pressure Limit (LP10 Only)
Note Since the pressure limit function bleeds off air to limit pressure, the vol-
SIMV (Synchronized
Intermittent Mandatory
Ventilation)
The ventilator functions as described under the Assist/Control mode.
The only difference is that the ventilator will limit the pressure during a
delivered breath.
ume of air delivered will be less than the set value.
In this mode, the patient can breathe unassisted and on his/her own
between ventilator delivered breaths. The ventilator monitors these
spontaneous breaths.
If the patient’s effort is not strong enough to turn on the Breathing
Effort light or the patient makes no effort, the ventilator delivers a controlled breath. All this depends on the breath rate setting:
Breath Rate set at 1 - 5 BPM
If the patient does not start a breath on their own for 20 seconds, the
Apnea alarm sounds and alerts the caregiver. Meanwhile, the ventilator
delivers breaths at 10 BPM at the selected volume.
Breath Rate set at 6 BPM or more
No alarms sound if the patient fails to start a breath. The ventilator continues to deliver breaths at the selected rate and volume.
