Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To create a database of physiological therapeutic responses to changes in FiO2 as captured by an inline data collecting box, for patients whilst on AIRVO2
MATERIALS
AIRVO2 flow source and Nasal High Flow cannula. An inline monitor will be installed in the circuit
PROCEDURES
All normal cares will prevail. One exception is the patient must wear a second independent SpO2 monitoring device on one of their fingers (Massimo SpO2 monitor a fully released and marketed device). The second device shall be worn continuously whilst on ARIVO therapy for a maximum of 10 days average expected to be less then 48hrs (based on historical data))
WHO
Consented Adult ICU patients with a requirement for respiratory support (delivered by AIRVO using nasal high flow cannula) as determined by the clinician in charge of their care. No other individual will be involved in the care of these patients
DELIVERY
All usual care shall prevail. The NHF shall be delivered by the ICU staff ( nurses and Drs)
DURATION
The therapy duration shall prevail as per standard care and by clinical need as determined by the clinician in charge of their care

Summary
Brief summary
The intensive monitoring of a patients’ physiological response to therapies such as Nasal High Flow is mandated and is a component of standard care. This physiological response data is used to inform clinical decision making and subsequent titration of a therapy to meet the dynamic and individual needs of a patient. Currently data on patient condition and oxygen delivery, if they are recorded, are recorded on discrete devices, making it difficult to relate them. It is proposed that a single device may record these data to allow analysis of patients’ physiologic response to changing NHF therapy. No such devices are currently available.
