- Fig. 1.
Aerosol detection. Detected particles/droplets (quantified by maximum light pixels/mm2) during open-mouth breathing during no oxygen support (none), non-rebreathing mask (NRM, 15 L/min), HFNC (60 L/min), and HFNC with normal saline nebulization (positive control for generating aerosolized microparticles). *P = .032 by repeated measures analysis of variance with post hoc least significant difference (LSD) analysis, as compared to all other groups. Data (mean ± SEM) from 3 subjects measured twice in separate experiments. HFNC = high-flow nasal cannula.

Aerosol size range from normal saline nebulization. Microparticle size distribution detected with laser diffraction during normal saline nebulization via high-flow nasal cannula treatment (positive control for generating aerosolized microparticles).

Aerosol visualization patterns. Particle/droplet visualization with laser light scattering from a healthy adult with the face oriented sideward from the left side. A: Receiving HFNC at 60 L/min; (B) during a single cough without respiratory support; and (C) during HFNC with normal saline nebulization for positive control of visualization of aerosolized microparticles. HFNC = high-flow nasal cannula.
