Jay, Gregory D., et al. Continuous Non-Invasive Measurement of Pulsus Paradoxus Complements Medical Decision Making of Acute Asthma Severity.Chest 130:754-765, 2006.
Pulsus paradoxus (PP) is a pathophysiological parameter that is indicative of asthma severity. This study found that continuous PP can aid in determining disposition among emergency department (ED) patients with acute asthma. ED physicians equipped with a PP monitor would be able to objectify the work of breathing and would more closely adhere to National Asthma Education and Prevention Program guidelines. The possibility that a PP detection algorithm could reside in a pulse oximeter warrants further investigation.
