CAUTION! Internal components are susceptible to damage from static discharge. Do not remove device
covers.
NOTE: This Operation Manual is not meant to supersede any controlling standard operating procedure
regarding the safe use of assisted ventilation.
NOTE: Follow all governing regulations regarding the disposal of any part of this medical device.
NOTE: Follow all governing regulations regarding the handling of materials contaminated by body fluids.
NOTE: Follow all governing regulations regarding shipment of the Li batteries.
WARNING! A pulse oximeter should not be used as an apnea monitor.
WARNING! A pulse oximeter should be considered an early warning device. As a trend towards patient
deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely
understand the patient’s condition.
WARNING! MEASUREMENTS
If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by
alternate means and then check the pulse oximeter for proper functioning.
Inaccurate measurements may be caused by:
Incorrect sensor application or use
Significant levels of dysfunctional hemoglobin (e.g., carboxyhemoglobin or methemoglobin)
Intravascular dyes such as indocyanine green or methylene blue
Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon light source),
bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight (exposure to excessive
illumination can be corrected by covering the sensor with a dark or opaque material)
Excessive patient movement
Venous pulsations
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular
line
The pulse oximeter can be used during defibrillation, but the readings may be inaccurate for a short
time.
WARNING! Interfering Substances: Carboxyhemoglobin may erroneously increase readings. The level of
increase is approximately equal to the amount of carboxyhemoglobin present. Dyes, or any substance
containing dyes, that change usual arterial pigmentation may cause erroneous readings.
WARNING! ALARMS Check alarm limits each time the pulse oximeter is used to ensure that they are
appropriate for the patient being monitored.
WARNING! Loss of pulse signal can occur in any of the following situations:
The sensor is too tight
There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp, or sunlight
A blood pressure cuff is inflated on the same extremity as the one with a SpO
2
sensor attached
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
There is arterial occlusion proximal to the sensor
The patient is in cardiac arrest or is in shock

MAINTENANCE
Operational inspection – after every 1,000 hours of use or more
frequently if the ventilator has been used in austere environments,
confirm that that device functions properly by power cycling the
ventilator while it is connected to a ventilator circuit and test lung.
Operate the ventilator at its default settings and exercise the
membrane buttons and the rotary optical encoder to ensure they
operate as intended.
Accessory inspection – replace power supply if there is damaged or
cracked casing, plugs, or cut/frayed or exposed wiring.
Filter inspection – check the foam and disk filter for dust/dirt build up
and/or physical damage. Replace if dirt is visible or filter is damaged.
Battery inspection – check the battery icon to ensure battery is
charging and that the ventilator operates correctly.
Breathing circuit inspection – check on a daily basis the breathing
circuit for damage or wear including but not limited to cracking,
discoloration or disfigurement. If there is any sign of physical
degradation or the unit is indicating breathing circuit problems,
replace with a new breathing circuit.
High Pressure Hoses inspection: Examine hoses for cracking,
discoloration and disfigurement. Wipe the exterior wall with a damp,
soapy cloth. Dry with a lint-free cloth. Examine end connection
fittings for damaged threads and sharp edges. Replace if defective,
DO NOT attempt to repair.
This device should be incorporated into a regular maintenance program to ensure safe and effective
operation. Electro-mechanical and pneumatic components are subject to wear and fatigue over time and
components will deteriorate more quickly when used continuously. To maintain safe operation, it is the
user's responsibility to ensure that periodic inspections and maintenance is performed and that
recommended maintenance is performed by Impact or a certified Impact trained technician.
Routine Inspections
Routine inspections should be performed on this ventilator at regular intervals and prior to its being placed
into service. Routine inspections consist of the following:
Cleaning
1. The ventilator’s outer case should be cleaned with a damp soapy cloth and thoroughly dried with a
lint-free cloth. Make sure that all exposed surfaces are cleaned and dried.
2. For general decontamination/cleaning situations, a 10% bleach solution applied with a damp cloth
is an effective decontaminant that can be used. Since the potential amount of contaminants that
our ventilators might be exposed to is so large, it is difficult to provide an appropriate cleaning
method for each type of exposure. An effective cleaning agent for one type of exposure may not be
effective with another and cleaning and sterilizing practices may vary between institutions. Impact
Instrumentation, Inc. suggests that each facility have in place a procedure for the cleaning and
disinfection of its medical equipment and that these procedures be consulted for further guidance.

CAUTION! DO NOT store batteries in a discharged condition.
and avoid using excessive amounts of water that might enter the unit.
4. Never use abrasives or chlorinated hydrocarbon based cleansers when cleaning the ventilator, they
will damage the plastic and interface lens.
Storage Information
For optimal prolonged storage periods, the device should be stored indoors. The environment should be
clean and out of direct sunlight. Storage in non-controlled environments is permissible if batteries are
removed.
For long-term storage, the optimum storage temperature range is -15 C to 21 C (5 F to 71 F). Battery life is
diminished at temperatures above 35 C (95 F). It is recommended that batteries be discharged to 50%
capacity if long term storage above 35 C (95 F) is expected. DO NOT store batteries in a discharged
condition. Short-term, less than 10 days, storage temperatures should range between -15 C to 49 C (5 F
and 120 F) with no degradation to the device.
When batteries are in extended storage, it is recommended that they receive a refresh charge at
recommended intervals when not continuously connected to an external power source:
STORAGE AMBIENT RECHARGE INTERVAL
Below 68 F (20 C) 12-months
68 F to 86 F (20 C to 30 C) 6-months
86 F to 104 F (30 C to 40 C) 3-months
Following periods of extended storage in non-controlled environments, allow the device sufficient time to
stabilize to a temperature within its specified operating range (see section entitled BATTERY CARE AND
RECHARGING).
If the device is subject to 6-months of continuous storage/non-use, or longer, this device should be powered
on to initiate the device’s self test routine. The user should confirm that the batteries are sufficiently
charged before patient-use is attempted.
Post-Contaminated Environment Cleaning
If the ventilator is operated in an environment where it may have been exposed to contamination from a
hazardous materials accident, mass epidemic or weapon of mass destruction, Impact recommends that the
guidelines below be followed.
1. The ventilator’s outer case should be cleaned with a damp soapy cloth and thoroughly dried
with a lint-free cloth. Make sure that all exposed surfaces are cleaned and dried.
2. For general decontamination/cleaning situations, a 10% bleach solution applied with a damp
cloth is an effective decontaminant that can be used. Since the potential amount of
contaminants that our ventilators might be exposed to is so large, it is difficult to provide an
appropriate cleaning method for each type of exposure. An effective cleaning agent for one
type of exposure may not be effective with another and cleaning and sterilizing practices may
vary between institutions. Impact Instrumentation, Inc. suggests that each facility have in place

a procedure for the cleaning and disinfection of its medical equipment and that these
CAUTION! Do not operate the compressor without a filter in place.
CAUTION! There are no user serviceable parts except the filter components described above.
CAUTION! When used in dusty/dirty environments the foam and disk filters should be checked, and
replaced as needed. This will prevent particle build up on the transducer screen and the need to take the
unit out of service for maintenance by a biomedical technician.
procedures be consulted for further guidance.
3. Care must be taken to prevent liquids from entering the ventilator. Never submerge the
ventilator and avoid using excessive amounts of water that might enter the unit.
4. Never use abrasives or chlorinated hydrocarbon based cleansers when cleaning the ventilator,
they will damage the plastic and interface lens.
5. Always follow the decontamination procedures specified by the local Incident Command Safety
Officer.
6. Equipment should be cleaned and decontaminated as soon as possible after use. Personnel
should always wear the appropriate Personal Protective Equipment while decontaminating
equipment.
7. The ventilator’s outer case should be cleaned with a damp soapy cloth and thoroughly dried
with a lint-free cloth. Make sure that all exposed surfaces are cleaned and dried.
8. For general decontamination/cleaning situations, a 10% bleach solution applied with a damp
cloth is an effective decontaminant that can be used. Since the potential amount of
contaminants that our ventilators might be exposed to is so large, it is difficult to provide an
appropriate cleaning method for each type of exposure. An effective cleaning agent for one
type of exposure may not be effective with another and cleaning and sterilizing practices may

ventilator and avoid using excessive amounts of water that might enter the unit.
10. Never use abrasives or chlorinated hydrocarbon based cleansers when cleaning the ventilator,
they will damage the plastic and interface lens.
Removable Foam Filter Replacement
Removable Foam Filter: The Removable Foam Filter is located on the right side of the ventilator. It should
be inspected and replaced if needed every 1,000 hours of operation or more frequently if used in dusty
environments. Remove the filter using a pair of tweezers or similar tool. Examine the filter for dirt, lint, or
general wear. Replace if necessary (Part # 465-0028-00). DO NOT attempt to clean this filter.
Fresh Gas/Emergency Air Intake Disk Filter Replacement
Fresh Gas/Emergency Air Intake Disk Filter: The Fresh Gas/Emergency Air Intake Disk Filter (Part #4650027-00) is located behind the Removable Foam Filter. This filter provides a second level of filtration to the
ambient air that is delivered to the patient. This filter must be checked periodically and replaced when
necessary. The device triggers an alarm when the combination of Removable Foam Filter and Fresh
Gas/Emergency Air Intake Disk Filter become dirty. This alarm signifies that the device is still able to deliver
the correct tidal volume but one or more of its filters need replacement. The Fresh Gas/Emergency Air
Intake Disk Filter can be visually inspected after the Removable Foam Filter is removed. If the filter appears
discolored it must be replaced. See Appendix 5 in the Operation Manual: Internal Filter Change/Insertion.
906-0731-04 Rev. B Sept. 2012 Page 11 of 68
Page 12
CAUTION! If filters have been exposed to biological matter dispose of them following Universal Precaution
procedures for your facility.
NOTE: Do not attempt to clean this filter and do not operate internal compressor without filter in place.
CAUTION! Only use the Power Supply provided with the unit. Use of any other power supply could cause
damage or create a fire and/or destroy the battery and unit.
CAUTION! If you witness a battery or the battery compartment starting to balloon, swell up, smoke or feel
excessively hot, turn off the unit, disconnect external power and observe it in a safe place for
approximately 15 minutes and send the unit for service. Never puncture or disassemble the battery packs
or cells.
CAUTION! Never attempt to completely discharge the battery by shorting or some other method and
never ship the battery in a completely discharged state.
CAUTION! During continuous, uninterrupted use (>100 hours) it is recommended that the ventilator be
disconnected from AC power for 30 seconds to allow the battery to run diagnostics while the battery is
discharging.
NOTE: The ventilator continuously monitors the available power sources; occasionally a false low priority
power alarm can be triggered for ~1 second. These false alarms immediately clear themselves.
Battery Capacity, Care and Recharging
While the unit is operating on battery power, users can best determine the relative amount of charge in the
internal battery by looking at the BATTERY Icon/Indicator. The BATTERY icon appears in outline form and is
filled with horizontal rows of lines indicating its current capacity. Each line represents approximately 5% of
battery capacity.
The device uses a rechargeable lithium-ion battery which offers a wide temperature operating range, does
not exhibit "memory" characteristics (reduced capacity) or vent hydrogen gas. The life of this battery
depends, to a great extent, upon the care it receives. Avoid exposing it to direct sunlight or heat sources
and never store the battery at temperatures above 76 °C (170 °F) for more than 2 hours. Following these
simple guidelines will prevent premature charge depletion and reduction of battery life.
If the unit was supplied without the battery installed or battery replacement is required see Appendix 4:
Internal Battery Change/Insertion.
1. Battery charging is controlled by ventilator in the temperature range of 0 C to 45 C (32F to 113 F)
to provide the best life time for the battery
2. The battery has a discharge (operational) temperature range of -25° to 49° C (-13 F to 120 F) (as
validated by Impact Instrumentation).
3. DO NOT store the ventilator with the batteries discharged. Always store with the battery fully
charged.
4. For long-term storage, the optimum storage temperature range is -15 C to 21 C (5 F to 71 F).
Lithium-ion batteries exhibit excellent charge retention characteristics. Prolonged periods of disuse will not
substantially reduce operating capability. If long-term storage/non-use is common, recharge the unit every
six months; this will insure that battery charge is maintained at 80% capacity or better. The 731 series
devices’ battery rapidly recharges to 90% of its capacity in approximately 2 hours. It will take approximately
another 2 hours of trickle-charging to top off the battery to 100% of its capacity. Continuous charging is
permissible with the supplied 12 VDC Power Cable or AC/DC Power Supply.
Operating power will always default to the external power source to preserve the internal battery charge.
This assures that power is available for transport use or emergency back-up. If the EXTERNAL POWER LOW/ FAIL
alarm occurs, the device will automatically revert to its internal batteries for operating power.
The BATTERY Icon/Indicator – indicates (1) the presence of a functional battery, (2) when the battery is
charging and (3) what its current capacity is. The BATTERY icon appears in outline form and is filled with

of lines cyclically scroll vertically, one row at a time, from the bottom row to the top. When the battery is
fully charged, the icon is completely filled with lines and scrolling stops. Each line represents approximately
5% of battery capacity. During internal battery operation a horizontal line “disappears” as battery capacity
is reduced by a 5% increment. The BATTERY icon will flash off/on when a BATTERY POWER LOW alarm occurs.
The icon will flash off/on and present with a diagonal line when no battery is connected.
Preventive Maintenance (PM)
Scheduled replacement of filters, batteries, seals and mechanical/pneumatic moving parts will ensure the
device is always operating at peak performance. The table below describes the scheduled interval for
routine parts replacement, calibration and functional testing. Ventilators used in extreme environments
may warrant earlier or more frequent maintenance scheduling.
Table 1 Maintenance Schedule.
Periodic Maintenance Check (PMC)
At start up, the device performs a self check that includes a check for pre-existing alarm conditions.
Following start up, the presence of alarm conditions is checked continuously. When in operation the
ventilator circuit connects to a pressure transducer in the ventilator. Periodically, the transducer
recalibrates itself using the ambient air pressure as a reference. This process maintains a consistent
transducer baseline over a wide temperature and altitude range to assure display, monitoring and triggering
accuracy.
The ventilator also automatically performs an AUTO CAL procedure that affects 3 transducer systems:
Compressor Flow, Oxygen Flow and Airway Pressure. The purpose of AUTO CAL is to compensate for small
temperature related drifts in the transducer offset (zeroing). The AUTO CAL is performed at start up during
the self check and then every 5 minutes thereafter. However, if a temperature change emceeing +/-1.5oC is
sensed, the AUTO CAL time interval is reduced automatically to assure a stable pressure measurement
baseline. This continuous correction for variations in ambient temperature and pressure enable the
ventilator to deliver targeted volumes and pressure over the entire operating altitude and temperature
ranges described in the operations manual.
The automated self check at start up and the AUTO CAL tests confirm that the device is operating within its
specifications when in use. If the start up or AUTO CAL tests fail, the unit will not operate. Because the
automated tests do not confirm that flow and pressure outputs from the device are verified against a
controlled external pressure, flow and temperature measurement device, the PMC procedure should be
done every 12 months or after 1,500 hours of use, or to reset the ‘performance maintenance check’ low

should also be performed whenever the operator suspects that the device is not functioning properly or
following mass deployment and before the device is returned to storage. If the device fails the PMC it
should be maintained by a certified Impact service technician in the field or at Impact authorized service
locations. A secure record of PMC results should be maintained for devices not returned to Impact for
maintenance.
Impact’s 731 series service tool the RCS is needed to perform the PMC and reset the ‘performance
maintenance check’ low priority alarm. This tool includes can be purchased from Impact for use by Impact
trained and certified biomedical technicians. Alternatively, 731 series can be sent to an Impact authorized
service center for PMC or other service requirements.
In addition to automating and documenting the PMC process, the RCS is also capable of calibrating the
device and installing and verifying software upgrades and updates to the 731 series of devices.
If you would like to return the ventilator to Impact for service please contact Impact prior to returning this
instrument. (Telephone 973.882.1212, email service@impactii.com). A Returned-Goods-Authorization
number (RGA #) will be issued. The RGA # must appear on both the packing slip and address label. This will
facilitate better tracking of the returned item and result in improved scheduling and handling.
Annual and 4-Year PM Kits are available to trained personnel and service centers.

Troubleshooting and Repairs
The device uses a comprehensive suite of alarms to alert the operator and guide their actions to resolve the
alarm condition and assure patient safety. At the onset of an alarm, the screen displays the alarm name and
then a series of context-sensitive help messages (see Figure 2 example). These messages serve to guide the
operator by presenting suggestions as to the cause and resolution of a particular alarm. When multiple
alarms occur they are prioritized and displayed based on the risk to the patient. Should the operator not be
able to correct the problem, the ventilator should be taken out of use and sent to an authorized Impact
repair facility.
Trained bio-med technicians are encouraged to use a systematic approach to solving issues with the
ventilator. Use the Alarm Category and Service Code matrices listed in Appendix to resolve the problem or
to identify the suggested replacement service kit. Check on-hand availability or order the kit(s) from Impact,
then follow the detailed instructions listed to replace the kit. Trained repair facilities can contact Impact’s
technical service department via email: service @impactii.com or by telephone toll free: 800-969-0750 or
973-882-1212 for troubleshooting and repair recommendations.
ALARM & PLOT LIST: FIGURE 2
Service Kits
Service kits, which are preassembled and factory tested subassemblies, are available should physical
damage or problems of an unforeseen nature arise. Service kits are available only to qualified trained
biomedical personnel or authorized Impact service centers. Each kit replacement must be followed by a
HiPot test (See section titled HiPot Testing ), then either by a functional test or a calibration and functional
test using the Remote Calibration System (RCS).The following table lists the kits for each 731 series model.
