Understanding the Impact of Respiratory Therapy
Understanding Healthcare Worker Exposure to Bio-aerosols
Evidence-based guidelines recommend the use of NHF for COVID-19 patients
"Among patients with severe COVID-19, use of [NHF] decreased the need for mechanical ventilation, compared with conventional low-flow oxygen therapy."
Wilson et al. 2021.
"We conclude instead that exertional respiratory activities themselves are the primary modes of aerosol generation and represent a greater transmission risk than is widely recognised currently.”
Winslow et al, 2021.
"This adds to the increasing evidence that for COVID-19, CPAP and NHF may not be procedures with a higher transmission risk that are associated with their 'aerosol generating' classification."
Hui et al, 2023.
"No increased risk of environmental contamination in the isolation rooms was observed in the use of [NHF] and NIV vs COT among patients with COVID-19 with respiratory failure." "There was no nosocomial infection involving staff members" Download PDF
