3-RESULTS
We assessed 5643 patients for eligibility, and 5556 subjects were
excluded because of mild bronchiolitis, no desaturation, comorbidity,
and the presence of respiratory illness other than bronchiolitis. Of 472
eligible patients, 134 were missed opportunities, and 251 parents
declined to participate in the study. Eighty-seven participants (48 in
LFO vs. 39 in HFNCO) were included in the study. Ten patients in LFO
therapy and one in HFNCO therapy (P = .02) needed an escalation
of care at 4 h (Figure 1). Baseline demographic and clinical
characteristics of patients were presented in Table 1.
