Exhaled patient derived aerosol dispersion during awake tracheal intubation with concurrent high flow nasal therapy
Study context
- Population
- Volunteer undergoing simulated awake tracheal intubation with concurrent high-flow nasal oxygen therapy in an operating room of a university teaching hospital
- Outcome
- Quantities, size distributions and spread of patient-derived aerosol particles (optical particle sizers at staff locations)
Methodological detailssimulated awake tracheal intubation, single-centre
- Simulated awake tracheal intubation
- Single-centre
Main finding
As reported in the abstract
Patient-derived aerosol concentration and dispersion
Greatest concentration within 0.5-1.0 m of the subject, along midline
2242 #/cm3
Concentration decreased towards ambient levels with increasing radial and longitudinal distance; ambient level
36.9 ± 5.1 #/cm3
Observational data: associations, not effects.
