Chapter 7. High flow therapy
The high flow therapy (HFT) feature is available for 3.00 software and above,
as well as V60 Plus. HFT is accessed from the Standby mode. For more
information, see “Standby” on page 6-20.
For principles of operation, see “High flow therapy” on page 4-6.
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

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.
WARNING: During high flow therapy (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.
NOTE: High flow therapy (HFT) is accessed only from the Standby window.
Standby mode cannot be entered if a high flow nasal cannula is
connected to the circuit.
