Aug. 2012. 1. DETERMINATION OF BLOOD PRESSURE AIM To record and interpret the systolic and diastolic BP using Sphygmomanometer. PRINCIPLE The cuff of the sphygmomanometer is wrapped around the arm of the subject. The bag is then inflated until the air pressure in the cuff overcomes the arterial pressure and obliterates the arterial lumen.
The human heart pumps blood through the arteries, which connect to smaller arterioles and then smaller capillaries. In this assignment, we will discuss the arterial blood pressure from several aspects, include definition, normal values for blood pressure, the most important factors affecting it, the mechanism involved in arterial blood pressure regulation, and the relevance between the pressure and the eye. Definition of blood pressure, it’s Normal value, and the factors that determine arterial blood pressure under physiologic conditions. Blood pressure refers to the force exerted by the blood against the inner walls of the blood vessels . This pressure produces when the heart contracts during the heartbeat cycle, which forces blood out
The cardiovascular system modifies heart rate, blood pressure and capillary beds to maintain body temperature around 37 degrees and blood pressure roughly around 120/80mmhg. The probable homeostatic responses to changes in the internal environment during exercise to the heart rate,
What instrument was used to measure each of the following? 1. Blood pressure Blood pressure Sphygmomanometer or Blood pressure Cuff 2. Cardiac output Cardiac output 3D imaging 3. Heart rate ECG of the heart rate Results Table 2: Effect of Exercise on Systolic and Diastolic Blood Pressure (SBP, SDP), Heart Rate (HR) and Stroke Volume (SV) Resting Values Immediately After exercise Systolic BP (mmHg) Diastolic BP (mmHg) HR (beats/min) SV (mL) Systolic BP (mmHg) Diastolic BP (mmHg) HR (beats/min) SV (mL) 120 83 74 0.08 146 81 147 0.106 121 81 74 0.075 149 84 146 0.108 125 83 73 0.075 146 81 146 0.109 122 82 74 0.077 147 82 146 0.108 147 82 146 0.108 Laboratory Report/ Nicole Shook/ Effect of Exercise on Arterial Pressure and Vascular Resistance/ Lisa Nelson/ 11.15.2014/ Page [1] of [4]Resting and Early Post-Exercise SBP and DBP 1.
Human Blood Pressure Range Diagram The 1st Number: Systolic pressure is the pressure generated when the heart contracts . The 2nd Number: Diastolic pressure is the blood pressure when the heart is relaxed. What is Normal Blood Pressure ? Buy and use a blood pressure monitor. Compare your BP reading with the numbers on the chart above.
148mmHg c. The range of normal resting systolic BP for the subjects in this experiment is 115-125 mmHg. Did systolic BP increase, decrease, or not change with exercise? Systolic blood pressure increased with exercise. 2. Resting and exercising diastolic BP a.
c. Is your example in part 1a an example of autoregulation or extrinsic regulation? Why? It is an example of extrinsic regulation because the heart’s beating faster was a response to the nervous system, which sensed the change in blood pressure and acted accordingly. 2a. After reading pages 12-15 of your textbook, please describe how a receptor, control center, and effector differ from one another.
The medical term for High Blood Pressure is Hypertension. In this reading you will learn the types of Blood Pressure, the causes of High Blood Pressure and the cure for High blood Pressure. There are two types of Blood Pressures an individual has. Systolic blood pressure and Diastolic blood pressure. Systolic pressure is the force of blood in the arteries as the heart beats.
An optimal range would be a Systolic Blood Pressure (mmHg): 120 or lower.and Diastolic Blood Pressure (mmHg): 80 or lower. [ (Unknown, 140 or Bust: New Goals for Your Blood Pressure, 2001) ] Systolic blood pressure reading is the peak pressure of blood in the arteries when the ventricles of the heart are going through a contraction. Diastolic measurement of pressure is the amount
Repolarization is the recharging of the heart after each heartbeat (VanPutte, 2011). There are five main components of an electrocardiogram: P, Q, R, S and T. The p waves, corresponds to depolarization of the atria (VanPutte, 2011). The QRS complex represents the progressive wave of ventricular depolarization (VanPutte, 2011). The T wave represents the repolarization of the ventricles. In this lab experiment four leads were used: one each on the left and right wrist and one each placed above the ankle of the left and right foot.
