High Flow Oxygen Therapy (HFOT)
Key Details
High Flow Oxygen Therapy (HFOT) Overview
High Flow Oxygen has become a standard therapy for the treatment of respiratory patients throughout the acute care hospital.
AquaVENT® High Flow Oxygen Therapy (HFOT) delivers flow rates greater than conventional oxygen therapy via a specific high flow nasal cannula (HFNC), which enables flow rates up to 70 L/min.
AquaVENT® breathing circuits heat and humidify the gases for patient comfort and to prevent drying of the respiratory airway.
Benefits include: Low variable PEEP, increased FiO2 and improved secretion clearance.
Low variable PEEP
HFOT via nasal cannula delivers flow dependent low levels of PEEP. Studies suggest 3cm/H2O at 70 litres of flow with the patients mouth closed. Lower pressures are delivered with the patient’s mouth open. For more information click here.

Increased FiO2
HFOT via nasal cannula flushes the carbon dioxide (CO2) out of the upper respiratory airway, avoiding rebreathing of CO2 and increasing the delivered FIO2.
Möller et al. demonstrated that fresh gas administered by HFNC at 30 L/min flushes the dead space in the nasal cavity.
Nasal high flow clears anatomical dead space in upper airway models.

Improved secretion clearance
Maintaining secretion clearance is critical to reduce the incidence of respiratory complications in patients with chronic respiratory conditions such as COPD, Asthma or post operative patients, where secretion clearance may be restricted.
Heated and humidified HFOT can be combined with PEP therapy.

HFOT - High Flow Oxygen Therapy Options
Nasal cannula and tracheostomy options available.
AquaNASE®
AquaNASE® cannula for HFHOT can be supplied with AquaVENT® breathing systems in a complete Flowkit.
Patients can eat, drink, communicate and mobilise pulmonary secretions without disrupting therapy support. Heated humidification helps prevent drying of upper airway mucosa increasing patient comfort during oxygen therapy. Flows closer to a patient’s inspiratory demand reduces ambient air entrainment and oxygen dilution.
Use AquaNASE® during patients non-invasive ventilation rest periods for oral hygiene, hydration, feeding, physiotherapy and managed weaning.
