Warnings and Cautions
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 GeneralWARNING:An alternative means of ventilation shall be available whenever the ventilator
is in use. If a fault is detected in the ventilator, disconnect the patient from it
and immediately start ventilation with such a device. The ventilator must be
removed from clinical use and serviced by authorized service personnel.
WARNING:Use the ventilator on spontaneously breathing patients only. It is an assist
ventilator and is intended to augment the ventilation of a spontaneously
breathing patient. It is not intended to provide the total ventilatory
requirements of the patient.
WARNING:We do not recommend you use the ventilator on patients who require
ventilation at predetermined tidal volumes. The ventilator provides continuous
positive airway pressure (CPAP) and positive pressure ventilation (S/T, PCV,
and AVAPS) and is indicated for assisted ventilation only. These modes do not
provide ventilation with guaranteed tidal volume delivery.
WARNING:We do not recommend you use AVAPS on patients who require rapid and
frequent IPAP adjustments to maintain a consistent tidal volume. AVAPS, a
volume targeted 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.
WARNING:To reduce the risk of CO
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
rebreathing, make sure EPAP pressures and

Warnings and Cautions
WARNING:To prevent possible asphyxia and to reduce the risk of CO2 rebreathing, take
these precautions with respect to mask and exhalation port use:
•Use only an oro-nasal mask with an anti-asphyxia valve or a nasal mask
for 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
rebreathing may occur.
WARNING:The patient’s exhaled volume can differ from the measured exhaled volume
due to leaks around the mask during noninvasive ventilation.
WARNING:To ensure normal air circulation and exchange, do not cover or block the
ports on the ventilator. Do not block the air inlet panel on the right side of the
ventilator.
from the circuit. Substantial CO2

WARNING:Do not cover or position the ventilator so as to adversely affect its operation
or performance. Use the ventilator in an upright position that does not block
the air inlet.
WARNING:To reduce the risk of the device overheating and possible burn injury, do not
block the fan intake at the rear of the ventilator.
WARNING:To prevent possible patient injury and possible water damage to the ventilator,
make sure the humidifier is set appropriately.
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.
WARNING:To prevent the possibility of inadequate humidification, pay close attention to
the humidifier’s functioning when operating the ventilator at an ambient
temperature > 30ºC (86ºF). The ventilator warms the air delivered to the
patient above ambient temperature, which may impair the humidifier’s
performance.
WARNING:To reduce the risk that the patient will aspirate condensed water from the
breathing circuit, position any humidifier lower than both the ventilator and
the patient.
WARNING:To prevent possible patient injury and equipment damage, do not turn the
humidifier 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.

Warnings and Cautions
WARNING:To reduce the risk of fire, use only patient circuits intended for use in oxygen-
enriched environments. Do not use antistatic or electrically conductive
tubing.
WARNING:To prevent patient or ventilator contamination, always use a main flow
bacteria filter on the patient gas outlet port. Filters not approved by Philips
may degrade system performance.
WARNING:During ventilation, patient exhalate is released into room air. Use of a patient
circuit with a filter on its exhalation port is recommended.
WARNING:To reduce the risk of bacterial contamination or damage, handle bacteria
filters with care.
WARNING:Any additional accessories in the patient circuit may substantially increase
flow resistance and impair ventilation.
WARNING:Avoid adding resistive circuit components on the patient side of the proximal
pressure line. Such components may defeat the disconnect alarm.
WARNING:To reduce the risk of strangulation from patient tubing, use a tubing support
arm and secure the proximal pressure line with clips.
WARNING:To reduce the risk of electric shock, connect the ventilator to an AC supply
mains with protective earth only.
WARNING:Do not use extension cords, adapters, or power cords with the ventilator that
are not approved by Philips.
WARNING: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 you switch the ventilator on. The retainer is designed to
hold the connector end of the Philips-supplied cord securely in place.
WARNING:The ventilator should not be positioned 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.
WARNING:To reduce the risk of electric shock, regularly inspect the AC power cord and
verify that it is not frayed or cracked.
WARNING:To reduce the risk of strangulation, route the power cord to avoid
entanglement.
WARNING:To reduce the risk of power failure to the ventilator, pay close attention to the
battery’s charge level. The battery’s operation time is approximate and is
affected by ventilator settings, discharge and recharge cycles, battery age,
and ambient temperature. Battery charge is reduced at low ambient
temperatures or in situations where the alarm is continuously sounding.
WARNING:Always check the status of the oxygen cylinders before using the ventilator
during transport.

Warnings and Cautions
WARNING:Provide external oxygen monitoring to minimize patient risk in case of O2
supply loss or ventilator failure.
WARNING:Always verify ventilator operation as described in the user manual before
using the ventilator on a patient. If the ventilator fails any tests, remove it
from clinical use immediately. Do not use the ventilator until necessary
repairs are completed and all tests have passed.
WARNING:To prevent possible patient injury due to nonannunciating alarms, verify the
operation of any remote alarm device before use.
WARNING:To prevent possible patient injury, always return alarm settings to hospital-
standard values after verifying ventilator operation.
WARNING:Manufacturer default settings are not appropriate for all patients. Prior to
using the ventilator, verify that the current alarm settings or defaults are
appropriate for each particular patient.
CAUTION: To prevent possible damage to the ventilator, ensure that the
connection to the oxygen supply is clean and unlubricated, and
that there is no water in the oxygen supply gas.
CAUTION: For 120 V equipment, grounding reliability can only be achieved
when it is connected to an equivalent receptacle marked “hospital
only” or “hospital grade.”
CAUTION: Oxygen hose configurations using SIS connectors generate higher
resistance to flow. Therefore, a supply pressure of 53 to 87 psig is
recommended when adding supplemental O
adapters such as the O
transport manifold.

2.3 OperationWARNING:To prevent possible patient injury, avoid setting alarm limits to extreme
values, which can render the alarm system useless.
WARNING:PPV limits are not intended to be the primary ventilator alarms and should not
be substituted for the alarms found in the Alarm Settings window.
WARNING:To prevent the delivery of excessive pressure or volume, set the PPV limits
appropriately. Delivery of excessive pressure or volume can occur from a
sudden 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.
WARNING:Nebulization or humidification can increase the resistance of breathing
system filters. When using a nebulizer or humidifier, monitor the breathing
system filter frequently for increased resistance and blockage.
WARNING:Using a jet nebulizer can cause inadvertent alarms and affect the accuracy of
delivered FiO
to 10 L/min or use a vibrating mesh nebulizer.

WARNING:When transitioning from ventilation to HFT, remove the NIV mask and use only
a Philips-approved HFT interface to minimize pressure buildup and patient
discomfort.
WARNING:When transitioning from HFT to ventilation, remove the nasal cannula as these
are restrictive and may defeat alarms such as patient disconnect. Using a
nasal cannula in an NIV mode may lead to hypercarbia due to the inability to
provide pressure support.
WARNING:Patient alarms are not available during HFT, as the therapy uses an open
system. A nasal cannula occupies only a portion of the nares and a patient
can breathe through the mouth, which prevents estimation of patient
parameters such as tidal volume, respiratory rate, pressure, and minute
ventilation. Provide external monitoring, including oximetry, to inform the
clinician of a change in the patient’s condition.
WARNING:During HFT, verify that an occlusive patient interface is not being used.
Occlusive patient interfaces include a cannula fully sealed within the nares,
an NIV mask, or a direct connection to a tracheostomy tube or endotracheal
tube. Remove any occlusive interface immediately as this may expose the
patient to unintended high pressures.
2.5 Alarms and
Messages
2.6 Care and
Maintenance
WARNING:If AC power fails and the backup battery is not installed or is depleted, an
audible and visual alarm annunciates for at least 2 minutes. Immediately
discontinue ventilator use and secure an alternative means of ventilation. As
in most ventilators with passive exhalation ports, when power is lost,
sufficient air is not provided through the circuit and exhaled air may be
rebreathed.
WARNING:To reduce the risk of electric shock, power down the ventilator and
disconnect it from AC power before cleaning, disinfecting, or servicing it.
WARNING:To prevent patient or ventilator contamination, inspect and replace the main
flow bacteria filter between patients and at regular intervals (or as stated by
the manufacturer).

Theory of Operation
3.1 PneumaticsThe pneumatic subsystem delivers and monitors pressurized gas to the patient
The V60/V60 Plus ventilator is a microprocessor-controlled gas flow control
and monitoring system that can deliver air and oxygen to augment or replace
the work normally performed by the patient’s respiratory system. The ventilator
uses electromechanical control circuits, flow and pressure monitors, and
software programs to deliver pressure controlled breaths.
The ventilator includes a user interface (UI), internal blower, and gas delivery
subsystem (GDS) that mixes air and oxygen. The ventilator can operate from a
40 to 87 psig (276 to 600 kPa) medical grade oxygen source for enriched
oxygen operation. The internal power supply that can operate from mains (100
to 240 V AC 50/60 Hz) or internal battery (14.4 V DC) power. The ventilator
also includes several communications interfaces.
Ventilator schematic diagrams are available upon request.
in response to commands from the CPU subsystem. The pneumatic subsystem
includes these components:
•Manifold
•Blower
•Oxygen solenoid valve
•Air and oxygen flow sensors
•Pressure transducers
•Solenoid valves
•Motor controller (MC) PCBA
•Data acquisition (DA) PCBA
The ventilator uses ambient air and high-pressure oxygen. Air enters through
an inlet filter. Oxygen enters though a high-pressure inlet, and a proportional
valve provides the operator-set concentration. The system mixes the air and
oxygen, pressurizes it in the blower, and then 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 single-limb patient breathing circuit, a humidification device
(optional), and a patient interface such as a mask 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 oxygen mixture.

description
Standard 1/4-inch female audio (ring, tip, sleeve) connector.
The remote alarm port allows high-priority alarm conditions to be
annunciated away form the ventilator (for example, when the
ventilator is in an isolation room). The ventilator sends alarm
signal to a remote alarm through the remote alarm connector at
the back of the ventilator.
WARNING:To prevent possible patient injury due to nonannunciating alarms, verify the
operation of any remote alarm device before use.
WARNING:To ensure the functionality of the remote alarm, connect only Philips-
approved cables to the remote alarm port.
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.
NOTE: Selecting Alarm Silence deactivates the remote alarm.

Results:
For any of the DAC Wrap signals, the ADC count out should be equal to the
DAC count in ± 23 counts over the full range of 0 to 4050 counts. An out-ofspecification result could be a fault in any one of the following:
•ADC chip internal fault
•DAC chip internal fault
•Addressing error of the ADC or DAC
•SPI interface failure (DAC only reads data from SPI bus, ADC reads
and writes data)
•DAC Wrap feedback path shorted to adjacent signal or open
Note that a fault of Vref will not necessarily show up here as the paired DAC
and ADC chips use a common reference voltage. There is at least one other
ADC input that is generated from a separate reference (that is, 3.3V supply)
that would fail if Vref were off significantly.
