The oxygen saturation in children presenting to the emergency room with acute asthma does not reliably predict their subsequent hospitalization, according to a report in the September issue of the Annals of Emergency Medicine.
Pulse oximetry assesses oxygenation rather than ventilation, the authors explain, and studies examining the use of oximetry in predicting asthma outcomes in children have yielded mixed results. Dr. Laine Keahey from Winnipeg Children’s Hospital in Winnipeg, Manitoba, Canada and colleagues examined whether initial room air oxygen saturation in 1040 children presenting to the emergency department with acute asthma reliably predicted hospital admission.
