Analysis of Blood Pressure
Analysis of Orthostatic Vital Signs The purpose of this assignment was to measure, document and analyse six recordings of orthostatic blood pressure, orthostatic pulse and respiratory rate on my lab partner. Orthostatic Hypotension is a condition when there is a drop in systolic pressure of more than 20 mm Hg, or orthostatic pulse increases of 20 bpm or more which occurs due to a quick change to a standing position (Jarvis, pp. 163). Six recordings were taken over a certain period of time to better understand the trends of the vital signs. The readings of vital signs data were taken by having my partner rest supine for one to three minutes and then the measurements with her sitting and then standing.
The trend noticed over the first five readings on average and also when she was not stressed is, her blood pressure was lowest lying down. This is because the body does not have to work very hard to pump blood around the body, which is in the same horizontal plane. When the body then sits up, there is an increase in blood pressure and heart rate. This is due to the heart now working harder to pump blood around the body. When a person rises to standing position there is slight drop in blood pressure because gravity causes blood to naturally pool about 300 to 800 mL in the lower extremities or leg causing a drop in blood pressure (Bradley & Davis, 2003). “Upon standing from a supine position, the normal response is an increase in heart rate to maintain blood pressure.” (Tse,H.F., et al, 2005) The autonomic nervous system tries to correct this by narrowing the blood vessels and therefore the blood pressure is maintained to its baseline. On average, her pulse rate was within the normal resting pulse rate (i.e. 60-100). Her pulse rates were higher though within the normal range when she was stressed. Pulse rates are higher due to anxiety or stress (Jarvis, pp. 155). Her respiration was slow and regulated and was within the normal limit of adult (i.e. 10-20 bpm). When a
