    ObjectiveTo compare pulse oximetry waveform systolic blood pressure measurements (POWSBP) to measurements obtained by noninvasive blood pressure measurement (NIBPM) during the transport of children.DesignA prospective, convenience sample.Setting And ParticipantsAll patients transported by a dedicated Pediatric Critical Care Transport Team were eligible for inclusion. Senior transport nurses with over 3 years of transport experience who had been instructed by the principal investigator (PI) in the technique, obtained the measurements and recorded the results. A convenience sample was obtained based on the presence or absence of one of the senior nurses on the transport team.MethodsMeasurements of blood pressure were obtained by POWSBP and NIBPM (PROPAQ@; Protocol Systems, Beaverton, OR) on pediatric patients during transport in moving ambulances or fixed wing aircraft. Measurement of systolic blood pressure by pulse oximetry (POWSBP) was obtained on all patients by observing the return of the plethysmographic waveform of the pulse oximeter as the blood pressure cuff deflated. The patients were divided into two groups; in group A POWSBP measurements were obtained by using the automated BP cuff from the PROPAQ@ and in group B by a manual BP cuff. These measurements were compared to NIBPM readings obtained at the same time. Between 3 and 13 paired readings were obtained for each patient. The actual transport time determined the number of measurements obtained.ResultsA total of 24 patients were enrolled in the study. Multiple matched pair readings (both POWSBP and NIBPM) were obtained from each patient for a total of 180 data points. A two variable linear regression model was run which identified a significant correlation between POWSBP and NIBPM. Group A, r = 0.7592 and r = 0.9477 for group B significant at P< 0.000001. Further, a corrective equation was developed for use with an automated BP cuff.ConclusionsThe use of pulse oximetry waveform systolic blood pressure measurement is a quick and easy method with which to obtain systolic blood pressure in children during transport and shows a close correlation to the standard noninvasive blood pressure measurement. If an automated blood pressure cuff is used, then a corrective equation [NIBP-S = 41.686 + 0.7377(POBPS)] is required. Further validation in a larger group of patients is recommended.
