Continuous Noninvasive Measurement of Pulsus Paradoxus Complements Medical Decision Making in Assessment of Acute Asthma Severity: Discussion

The greater number of patients who had been unnecessarily admitted to the hospital may reflect the conservative approach that many physicians have in the management of asthma. The alternate disposition indicated by AT-PP supports its inclusion as an adjunct tool in patient assessment. Relapsing patients who had been discharged from the hospital are comparatively less […]

Continuous Noninvasive Measurement of Pulsus Paradoxus Complements Medical Decision Making in Assessment of Acute Asthma Severity: Oximeter Plethysmography Measures PP (Volunteer Subject)

Oximetry plethysmography also showed PP-like phenomena, which correspond to the BP measured PP events (Fig 4, top, A). A linear regression model describes a transfer function, which relates AT-PP in units of millimeters of Hg to a decrease in plethys-mographic amplitude (Fig 4, bottom, B). The slope of this relationship is roughly 0.01 V/mm Hg, […]

Continuous Noninvasive Measurement of Pulsus Paradoxus Complements Medical Decision Making in Assessment of Acute Asthma Severity: Descriptive Statistics

Seventy-nine patients were enrolled in this study from September 2003 to June 2005 as a convenience sample. Nine patients were excluded from the analysis as they failed to meet study asthma criteria following post hoc inspection of both outpatient and inpatient records. Of the remaining 70 patients, 19 (27.1%) were admitted to the hospital from […]
