The Philips Respironics V60/V60 Plus ventilator is a microprocessor-controlled, positive
pressure ventilator assist system. The ventilator provides noninvasive and invasive
ventilatory support for spontaneously breathing adult and pediatric patients.
The ventilator has a variety of modes and monitoring capabilities to assist in assessing
performance and patient-to-ventilator synchrony. Safety features include in-depth alarms
and a variety of integrated safety and self-diagnostic features. The ventilator automatically
checks many system functions at startup and during operation.
The ventilator includes a touchscreen user interface (UI) that lets the operator select
entilator and alarm settings and displays of ventilator and patient data.
v
The ventilator is designed to be upgradeable, and features communications capabilities and
an
internal backup battery.
Read this manual thoroughly before performing service or maintenance on the ventilator.
T
his manual includes advanced troubleshooting, calibration, and maintenance instructions
for the ventilator. All maintenance and repair work should be performed by qualified
biomedical technicians who have appropriate training and authorization to provide
maintenance, repair, and service for the ventilator.
Review the operating instructions for the ventilator before running tests, checking
rational readiness, or initiating patient use. These instructions include important
ope
information about ventilator safety and operation.

ote alarm systems, refer to the appropriate instruction manual prior to operating the
rem
ventilator. Review the applicable warnings and cautions in the ventilator user manual before
operating the ventilator.
1.1 Intended Use
The V60/V60 Plus ventilator is an assist ventilator and is intended to augment patient
breathing. In high flow therapy (HFT), the ventilator can also provide respiratory support.
the ventilator is intended for spontaneously breathing individuals who require mechanical
ventilation and respiratory support: patients with respiratory failure, chronic respiratory
insufficiency, or obstructive sleep apnea in a hospital or other institutional settings under
the direction of a physician.
The ventilator is intended to support pediatric patients weighing 20 kg/44 lb or greater to
patients. It is also intended for intubated patients meeting the same selection criteria
adult
as the noninvasive applications. The ventilator is intended to be used by qualified medical
professionals such as physicians, nurses, and respiratory therapists. The ventilator is
intended to be used only with various combinations of Philips-recommended patient
circuits, interfaces (masks), humidifiers, and other accessories.

Before servicing the V60/V60 Plus ventilator, read and understand this service manual,
especially safety considerations. These safety considerations are for reference only, and are
not intended to supersede your institution’s protocol for service or safe use of noninvasive
ventilation.
The instructions in this manual are primarily reserved for use by an authorized service
technician.
WARNING
Alerts the user to the possibility of injury, death, or other serious adverse reactions
associated with the use or misuse of the device.
CAUTION
Alerts the user to the possibility of a problem with the device associated with its use or
misuse, such as device malfunction, device failure, damage to the device, or damage to
other property.
NOTE
Emphasizes information of particular importance.
2.1 General
WARNING
• Always have immediate access to an alternative means of ventilation. If there is a
ventilator failure, immediately remove the ventilator from use and secure an
alternative means of ventilation, such as a self-inflating, manually powered
resuscitator and mask. Failure to do so can result in patient injury or death.
• Use the ventilator on spontaneously breathing patients only. It is an assist
entilator and is intended to augment the ventilation of a spontaneously
v
breathing patient. It is not intended to provide the total ventilatory requirements
of the patient.
• We do not recommend using the ventilator on patients who require ventilation at
edetermined tidal volumes. The ventilator provides CPAP and positive pressure
pr
ventilation (S/T, PCV, and AVAPS) and is indicated for assisted ventilation only.
These modes do not provide ventilation with guaranteed tidal volume delivery.
• We do not recommend using AVAPS on patients who require rapid and frequent
AP adjustments to maintain a consistent tidal volume. AVAPS, a volume targeted
IP
mode, changes the IPAP setting in order to achieve the target tidal volume. During
AVAPS setup, there may be a period of time before the target tidal volume is
achieved. AVAPS is ideal for more stabilized patients.

Page 25
WARNING
• To reduce the risk of CO2 rebreathing, make sure that EPAP pressures and
exhalation times are sufficient to clear all exhaled gas through the exhalation port.
In noninvasive ventilation continuous air flow through the port flushes exhaled
gases from the circuit. The ability to completely exhaust exhaled gas from the
circuit depends on the EPAP setting and I:E ratio. Higher tidal volumes further
increase the volume of CO
that the patient rebreathes Note: this may occur if
2
exhalation time is insufficient.
• To reduce the risk of CO
rebreathing, monitor the patient for changes in
2
respiratory status at the start of ventilation and with each change in ventilator
settings, circuit configuration, or patient condition. Pay attention to ventilator
alarms that warn of increased CO

• Set the alarm loudness above the ambient level. Setting the alarm loudness too
low ma
y prevent recognition of alarm conditions.
• Avoid blocking the alarm speakers beneath the ventilator.
• Do not leave the ventilator unattended when stationed on an incline.
• The ventilator may cause radio interference or may disrupt the operation of
arby equipment. It may be necessary to take mitigation measures, such as re-
ne
orienting or relocating the ventilator or shielding the location.
• The ventilator is designed to comply with IEC 60601-1-2. The ventilator generates,
s, and can radiate radio frequency energy and, if not installed and used in
use
accordance with instructions, may cause harmful interference to other devices in
the vicinity. However, there is no guarantee that interference will not occur in a
particular installation. Harmful interference to other devices can be determined
by turning this equipment ON and OFF. Try to correct the interference using one or
more of the following:
- Reorient or relocate the receiving device
Increase the separation between the equipment
-
- Connect the equipment to an outlet on a different circuit from that to which the
other device(s) are connected and consult the Philips service technician for help

• Use portable radio-frequency (RF) communications equipment (including
ripherals such as antenna cables and external antennas) no closer than 30 cm
pe
2 in.) to any part of the ventilator system, including cables specified for use with
(1
he ventilator. Otherwise, equipment performance can be degraded. If higher
t
immunity test levels than those specified in IEC 60601-1-2:2014, Table 9, are used,
the minimum separation distance may be lowered. Lower minimum separation
distances shall be calculated using the equation specified in chapter 8.10 of the
standard.
• Do not use the ventilator near radio-frequency identification (RFID) or
ectromagnetic security systems. The ventilator may disrupt the operation of this
el
equipment.
• Do not use the ventilator near active high frequency (HF) surgical equipment,
dical devices such as X-ray devices and diathermy, or in an RF-shielded room of
me
medical equipment or system for magnetic resonance imaging, where the
intensity of electromagnetic (EM) disturbances is high. These devices may degrade
the performance of the ventilator.
CAUTION
• Federal law (USA) restricts this device to sale by or on the order of a physician.
• The ventilator is designed to operate in the temperature range of 5°C to 40°C (41°F
o 104°F). To minimize the risk of overheating the device, do not operate adjacent
t
to heaters or other heat sources.
NOTE
• The displays shown in this manual may not exactly match what you see on the ventilator.
• Pressures are indicated on the ventilator in cmH
O. Millibars and hectopascals (hPa) are
2
used by some institutions instead. Since 1 millibar equals 1 hPa, which equals
1.016 cmH
O, the units may be used interchangeably.

• The ventilator is not intended for use as an ambulance transport ventilator or as an
Automatic Transport Ventilator as described by the American Hospital Association and
referenced by the FDA. It is intended for to allow the patient to be transported within the
hospital setting using a stand to move the ventilator.
• When attachments or other components or subassemblies are added to the ventilator
breathing system, the pressure gradient across the ventilator breathing system,
measured with respect to the ventilator outlet, may increase.
• To ensure the correct performance of the ventilator and the accuracy of patient data, use
only Philips-approved accessories with the ventilator. See the user manual for more
information.

2.2 Preparing for Ventilation
WARNING
• Connect the ventilator only to an appropriate medical-grade O2 source.
• To reduce the risk of hypoxia, connect only O
the rear of the ventilator.
• The ventilator can be used as a high-flow device. Connect it only to a gas supply
ystem that can provide adequate flow to all terminal outlets. Connecting the
s
ventilator to an adequate gas supply system helps ensure that the ventilator and
other connected devices perform to their specifications.
• To reduce the risk of fire, do not use a high-pressure O
contaminated with combustible materials like grease or oil.
• The ventilator is designed to use ambient air and high pressure 100% O
gases should be used.
• Do not use the ventilator with helium or helium mixtures. The ventilator is not
tended to be used with helium or heliox. Connecting helium to the ventilator
in
may affect ventilator performance, gas mixtures, and measurements due to the
lower density of helium.
• Do not use the V60/V60 Plus ventilator with nitric oxide. The ventilator is not
alidated for use with nitric oxide.
v
• To prevent possible asphyxia and to reduce the risk of CO
precautions with respect to mask and exhalation port use:
- Use only an oro-nasal mask with an an
noninvasive ventilation.
- Do not occlude the exhalation port.
- Turn on the ventilator and verify that the port is operational before application.
Pressurized gas from the ventilator should cause a continuous flow of air to exhaust
from the leak port, flushing exhaled gas from the circuit.
- Never leave the mask on the patient while the ventilator is not operating. When the
ventilator is not operating, the exhalation port does not let sufficient exhaust
eliminate CO
from the circuit. Substantial CO2 rebreathing may occur.
2
• The patient’s exhaled volume can differ from the measured exhaled volume due
o leaks around the mask during noninvasive ventilation.
t
• To ensure normal air circulation and exchange, do not cover or block the ports on
he ventilator. Do not block the air inlet panel on the right side of the ventilator.
t
• Do not cover or position the ventilator so as to adversely affect its operation or
rformance. For example, positioning the ventilator next to a curtain blocks the
pe
flow of cooling air and can cause the equipment to overheat. Use the ventilator in
an upright position that does not block the air inlet.
• Do not block the air intake. Blocking the intake can impair ventilator performance
result in patient injury.
and
• To reduce the risk of the device overheating and possible burn injury, do not block
he fan intake at the rear of the ventilator.

WARNING
• When using a humidifier, always use either a circuit with a water trap or a heated
wire circuit to minimize patient risk from condensate in the circuit.
• To prevent the possibility of inadequate humidification, pay close attention to the
humidifie
r’s functioning when operating the ventilator at an ambient temperature
> 30°C (86°F). The ventilator warms the air delivered to the patient above ambient
temperature, which may impair the humidifier’s performance.
• To reduce the risk that the patient will aspirate condensed water from the
eathing circuit, position any humidifier lower than both the ventilator and the
br
patient.
• To prevent possible patient injury and equipment damage, do not turn the
humidifie
r on until the gas flow has started and is regulated. Starting the heater or
leaving it on without gas flow for prolonged periods may result in heat build-up,
causing a bolus of hot air to be delivered to the patient. Circuit tubing may melt
under these conditions. Turn the heater power switch off before stopping gas
flow.
• To reduce the risk of fire, use only patient circuits intended for use in O
-enriched
2
environments. Do not use antistatic or electrically conductive tubing.
• To prevent patient or ventilator contamination, always use a main flow bacteria
er on the patient gas outlet port. Filters not approved by Philips may degrade
filt
system performance.
• During ventilation, patient exhalate is released into room air. Use of a patient
ircuit with a filter on its exhalation port is recommended.
c
• Avoid adding any components to the patie
nt circuit that are not absolutely
necessary. Additional components installed in the patient circuit can change the
pressure gradient across the ventilator breathing system, increase dead space, and
adversely affect the ventilator performance.
• To reduce the risk of bacterial contamination or damage, handle bacteria filters

• Do not use extension cords, adapters, or power cords with the ventilator that are
not appr
oved by Philips.
• To prevent unintentional disconnection of the power cord, always use the correct,
Philips-supplied
power cord and lock it into place with the power cord retainer
before switching the ventilator on. The retainer is designed to hold the connector
end of the Philips-supplied cord securely in place.

WARNING
• Do not position the V60/V60 Plus ventilator in a way that makes it difficult to
disconnect from mains power if necessary. Disconnect from supply mains by
removing the power cord from the wall outlet. The AC mains plug is used as a
disconnection device.
• To reduce the risk of electric shock, regularly inspect the AC power cord and verify
hat it is not frayed or cracked.
t
• To reduce the risk of strangulation, route the power cord to avoid entanglement.
• To reduce the risk of power failure to the ventilator, pay close attention to the
ttery’s charge level. The battery’s operation time is approximate and is affected
ba
by ventilator settings, discharge and recharge cycles, battery age, and ambient
temperature.
• Always check the status of the O
cylinders before using the ventilator during
2
transport.
•Provide external O
monitoring to minimize patient risk in case of O2 supply loss or
2
ventilator failure.
• Always verify ventilator operation as described in the user manual before using
he ventilator on a patient. If the ventilator fails any tests, remove it from clinical
t
use immediately. Do not use the ventilator until necessary repairs are completed
and all tests have passed.
• To prevent possible patient injury due to nonannunciating alarms, verify the
ration of any remote alarm device before use.
ope
• To prevent possible patient injury, always
return alarm settings to hospital-
standard values after verifying ventilator operation.
• Manufacturer default settings are not appropriate for all patients. Prior to using
e ventilator, verify that the current alarm settings or defaults are appropriate for
th
each particular patient.
CAUTION
• To prevent possible damage to the ventilator, ensure that the connection to the O2
supply is clean and unlubricated, and that there is no water in the O
supply gas.

2.3 Operation
WARNING
• To prevent possible patient injury, avoid setting alarm limits to extreme values,
which can render the alarm system useless.
• PPV limits are not intended to be the primary ventilator alarms and should not be
stituted for the alarms found in the Alarm Settings window.
sub
• To prevent the delivery of excessive pressure or volume, set the PPV limits
opriately. Delivery of excessive pressure or volume can occur from a sudden
appr
increase in mask leak, inappropriate settings, or a plugged or kinked proximal
pressure line. Conversely, insufficient treatment may result if limits are set too
low.
• Nebulization or humidification can increase the resistance of breathing system
ers. When using a nebulizer or humidifier, monitor the breathing system filter

the battery may become over-discharged and require long recharge times of up to
16 hours or more. The over-discharged condition may permanently damage the
ttery so that it is unable to recharge. To prevent the occurrence of a non-
ba
recoverable over-discharged battery, always keep the ventilator connected to an AC
outlet. Schedule regular preventive maintenance to ensure battery health.
• If the ventilator battery becomes completely discharged (non-recoverable), the
ventilator stops charging the battery after one hour.

Page 35
NOTE
• The backup battery is intended for short-term use only. It is not intended to be a primary
power source.
• Philips recommends that the ventilator battery is fully charged before ventilating a
patient. If the batteries are not fully charged and AC power fails, always pay close
attention to the level of battery charge.
• Install and charge a new backup battery within one year of the date of manufacture
identified on the battery and on the shipping box.
• Storing the battery for an extended period of time after its manufacture date without
being put into service, or at temperatures that exceed its limits, increases the risk of
discharge whereby the battery is unable to be recharged by the ventilator.
• Batteries that are not installed in the ventilator should be stored at -20°C to 25°C and
charged at least once per year.
• Lithium ion batteries are shipped with a charge level of under 30%, which may further
impact the time until the battery is charged and discharged.
• The battery charge level displays within about a minute of power on.
• A new battery must be charged for at least 5 hours before being placed into service.
Based on the age and state of the battery, it may take up to 16 hours or more to fully
charge the battery.
2.8 First-Time Installation
WARNING
Never attempt to disconnect or reconnect the battery during operation.
CAUTION
To prevent possible damage to the ventilator, always secure it to its stand or securely place it
on a flat, stable surface that is free of dirt and debris. Do not use the ventilator adjacent to,
or stack it with, other equipment.

2.9 Communications Interface
WARNING
• Connect to the ventilator only items that are specified as part of or compatible
with the ventilator system. Additional equipment connected to medical electrical
equipment must comply with the respective IEC or ISO standards. Furthermore, all
configurations shall comply with the requirements for medical electrical systems
(see IEC 60601-1-1 or clause 16 of edition 3 of IEC 60601-1, respectively). Anybody
connecting additional equipment to medical electrical equipment configures a
medical system and is therefore responsible for ensuring that the system complies
with the requirements for medical electrical systems. Also be aware that local laws
may take priority over the above mentioned requirements. If in doubt, consult
Philips.
• The USB port is not currently available for use. DO NOT connect or attempt to
er any equipment from the USB port.
pow
• It is the responsibility of the end user to validate the compatibility and use of
nformation transmitted from the ventilator with the device to be connected to
i
the ventilator.
• The data provided through the communications interface is for reference only.
isions for patient care should be based on the clinician’s observations of the
Dec
patient.
• To prevent possible patient injury due to nonannunciating alarms, verify the
ration of any remote alarm device before use.
ope
• To ensure the functionality of the remote alarm, connect only Philips-approved
bles to the remote alarm port.
ca
CAUTION
The remote alarm port is intended to connect only to an SELV (safety extra-low voltage) and
ungrounded system with basic insulation to ground, in accordance with IEC 60601-1. To
prevent damage to the remote alarm, make sure the signal input does not exceed the
maximum rating of 24 VAC or 36 VDC at 500 mA with a minimum current of 1 mA.

The ventilator uses AC mains as its primary power source. If AC power fails, the ventilator
aut
omatically switches to operation on backup battery without interrupting ventilation. The
battery powers the ventilator until AC power is connected or the battery is depleted.
Ventilator schematic diagrams are available upon request.
3.1 Pneumatics
The pneumatic subsystem delivers and monitors pressurized gas to the patient in response
to commands from the CPU subsystem. The pneumatic subsystem includes these
components:
•Manifold
•Blower
• Oxygen solenoid valve
• Air and O
flow sensors
2
• Pressure transducers
• Solenoid valves
• Motor controller (MC) PCBA
• Data acquisition (DA) PCBA
The ventilator uses ambient air and high-pressure O
. Air enters through an inlet filter. O2
2
enters though a high-pressure inlet, and a proportional valve provides the operator-set
concentration. The system mixes the air and O
, pressurizes it in the blower, and then
2
regulates it to the user-set pressure. To do this, the ventilator compares the proximal
(patient) pressure measurement with the ventilator outlet (machine) pressure, and adjusts
the machine pressure to compensate for the pressure drop across the inspiratory filter,
patient circuit, and humidifier. This helps ensure accurate and responsive pressure delivery
and leak compensation.
The ventilator delivers gas to the patient through a main flow (inspiratory) bacteria filter, a
-limb patient breathing circuit, a humidification device (optional), and a patient
single
interface such as a mask, high flow nasal cannula, or ET tube. A pressure tap proximal to the
patient is used to monitor patient pressure. The internal exhalation port continually clears
gas from the ventilator airway to ensure delivery of an accurate O
mixture.
