Abstract
Mean blood pressure and heart rate are parameters that are affected directly by the position of the sleeve with respect to the longitudinal median line of the body. Due to the different positions of the sleeve, the hydrostatic column and gravity affect the venous return, which is regulated by the baroreflex. The average blood pressure increases when the cuff is hanging from the table and decreases when the cuff is found in a position of 90 ° with respect to the longitudinal line of the body (F = 6.48; g.l = 2-39; P = 0.0037). The heart rate is the same regardless of the position of the cuff (F = 0.60, g.l = 2-39, p = 0.55). The position of the cuff is of clinical importance, that without a correct position of this, the gravity and the hydrostatic column will affect the values of both the mean arterial pressure and the heart rate and consequently, the Patient assessment.
