Warnings, cautions, and notes
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
2
accessories with SIS
adapters such as the O
2
transport manifold.
NOTE: The V60/V60 Plus Ventilator is a single-limb device with substantial
intentional and unintentional leak in the ventilator breathing system.
Under those conditions, CO
2
cannot be measured accurately.
Therefore, we do not recommend the use of CO
2
monitoring.
Operation
WARNING: 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
2
. To reduce patient risk, use only an approved
nebulizer.
Operation in high flow
therapy (HFT)
WARNING: When transitioning from a high flow therapy interface to an NIV mask,
ensure that an exhalation port is placed in the circuit and is unobstructed
to reduce the risk of CO
2
rebreathing.
WARNING: When transitioning from ventilation to high flow therapy, remove the NIV
mask and use only a Philips-approved high flow patient interface to
minimize pressure build-up and patient discomfort.
WARNING: When transitioning from high flow therapy to ventilation, remove the high
flow nasal cannula as it is restrictive and may defeat alarms such as
patient disconnect. Using a high flow 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 high flow therapy (HFT) as the
therapy uses an open system. A high flow nasal cannula occupies only a
portion of the nares and patients can breathe through their 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.
