Abstract |
Non invasive blood pressures measured by the Dinamap monitor, an oscillometric device, were
compared with the invasive radial artery pressure in neonates.
There were 21 patients with a mean age of 16.5 days (ranges 7 days to 1 month) and a mean body
weight of 3.3 kg. The invasive radial artery pressures were recorded on a strip chart and comparisons
were made between the noninvasive readings and simultaneously measured invasive readings.
The linear regression equation between the invasive (y) and the Dinamap(x) readings (with correla-
tion coefficient) was y = 0.9x + 4.55 (r=0.84) for systolic, y = 0.93x + 0.57(r=0.75) for diastolic, and y =
0.95x + 0.83(r=0.86) for mean pressures.
The error (blood pressure differences) was defined as the nonivasive reading minus the invasive
reading. The mean error±SD was 3.07 ±3.57 for systolic, 2.11 ±4.71 for diastolic, and 2.03 ±3.37
mmHg for mean pressures by the Dinamap method.
The results show that Dinamap blood pressures correlate well with the invasive radial artery
pressure, and the mean error is smaller with the Dinamap method. |
