Blood Pressure Measurement: Sitting and Standing?doi:10.1002/clc.20543Tsung O. ChengThe George Washington University WashingtonClinical Cardiology
The variability of casual (office) blood pressure according to position at the time of measurement was investigated in 168 untreated patients with a history of mild to moderate essential hypertension. Two measurements were made in the supine, sitting, and standing positions on each of 2 consective...
Results indicate a significant effect (p= 0.02) of oral contraceptives on mean arterial pressure(MAP) in the sitting position (NOC: 74.4 ± 4.4 vs OC: 92.4 ± 4.8 mmHg), but no effect of menstrual cycle phase. Despite significant differences in baseline MAP, there was no difference in the...
The differences were mainly due to girls vs boys having lower stroke volume while lying down, standing (adjusted difference, 4 mL; 95% CI, 1-7 mL), and sitting, and lower total peripheral resistance during the math-stress test (adjusted difference, 0.14 mm Hg . s/mL; 95% CI, 0.09-...
Types of Low Blood Pressure There are a few major types of hypotension: Orthostatic hypotension, or postural hypotension. OH is a sudden drop in blood pressure that occurs when you go from lying down or sitting to standing. It can be caused by or linked to a number of health conditions, ...
If someone has been sitting without standing for 6 hours, and blood has been pooling in their veins, why would they feel dizzy when they stood up? How does this related to stroke volume and mean arterial pressure? Fill in the blanks. When the pH of the arter...
Don't be surprised if your Body Cardio reports a higher heart rate than other devices. It reads the pulse in your feet, so it takes a standing heart rate rather than a sitting heart rate like a fitness watch does. It also uses Withings' Health Mate app to collect data, w...
History or clinical evidence of orthostatic hypotension, evaluated by comparing sitting and standing BP during the run-in visit; Clinical history of autonomic dysfunction or diabetic neuropathy (for diabetic hypertensives); Involvement in physical training programs and/or reported regular exercise habit; ...

Inclusion criteria for objective (1) were: (i) peripheral blood pressure was assessed non-invasively in the upper limb pre-sitting and post-sitting; (ii) studies were either randomised controlled, randomised crossover or quasi-experimental pre-test vs post-test trials; (iii) the sitting period...
