Comparisons of blood pressure measurements by auscultation and Physiometrics Infrasonde recording techniques.

چکیده
The levels of blood pressures measured by a Physiometrics Infrasonde recorder (model SR-2) were compared with the levels simultaneously measured byt auscultation utilizing a standard mercury sphygmomanometer (Baumanometer). The measurements were made on 1530 adult women and their 1760 adolescent children 15-17 years old. Two sets of blood pressures were taken about 3 minutes apart, each with an occluding cuff connected to the Physiometrics recorder as well as to the mercury sphygmomanometer. The reproducibility of the Physiometrics method was similar to that of the auscultation method. The means of the systolic pressures measured by the Physiometrics method were virtually equal to those of the auscultation method for women and girls; for boys, the means of the former method surpassed those of the latter by about 3 mm. The mean diastolic pressures by the Physiometric method were very close to the Korotkoff sound 5 (K5) pressure by the auscultation method for all three groups. The correlation coefficients between both methods were 0.98 for the systolic and 0.93 for the diastolic pressure of the adult women, and 0.94 for the systolic pressure of the adolescents. The correlations between the two diastolic pressures of adolescents were much less (0.69). The Physiometrics measurements were consistent with the measurements by auscultation for systolic and diastolic pressures of women and systolic pressure of adolescents, but the consistency was low for diastolic pressure of adolescents. An effort has been made to relate differences between the two methods with other anthropometric variables, but the correlations with these variables were of low level.

متن کاملComparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement
Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...
متن کاملClinical evaluation of the Infrasonde D4000 blood pressure monitor.
Choosing a blood pressure machine from their ever increasing number is often difficult due to lack of performance data. We have evaluated a new automated non-invasive blood pressure recorder, the Infrasonde D4000. In comparison with the Hawksley random zero mercury sphygmomanometer the Infrasonde showed less variability for both systolic and diastolic readings. However, it was found to record s...
متن کاملConcurrent validity studies of blood pressure instrumentation. The Philadelphia Blood Pressure Project.
There is increasing evidence that blood pressure (BP) screening during adolescence may detect early evidence of hypertensive disease. Choice of instrumentation becomes important to maximize the accuracy and interpretive value of several serial readings. We therefore conducted two studies of adolescents, comparing auscultatory (Baumanometer and Random-zero), ultrasonic (Arteriosonde 1216), and i...
متن کاملAssessment of techniques for measurement of blood pressure in infants and children.
Assessment of techniques for measurement of blood pressure in infants and children. Indirect techniques for blood pressure (BP) measurement in infants and children include palpation, auscultation, flush, and the Doppler shift technique. In a double-blind controlled trial these indirect methods were compared to direct intra-arterial measurements. 22 children, aged 1 to 11 years, had their BP mea...
