Question

TALE 5-3 5. It is important to make sure the medical data is cbtained in a proper m er example, many doctors thouth budy builders usually had high blood pressure. Then, a doctor tried a different cuff and got different results. Examine Table 5-3. a. Why do you think the readings are different Systolic Reading on Bodybuilders with Bicep circumference Larger Than 35 cm Reading taken with medium cut Reading taken with large cull 152 mm 51 mm Hg 145 mm Hg 122 mm Hg 130 mm Hg 132 mm Hg 152 mm Hg 148 mm Hg 125 mm Hg b. Which cuff do you think gave the more accurate reading 4. A patient was having her blood pressure taken by a nursing student. The nursing student became distracted and left the pressurized cuff on for much too long. What symptoms would the patient have? 5. Occasionally, the sphygmomanometer needs to be inflated to 200 mm Hg. When do you think that has to happen? 6. The posterior tibia can be palpated to find a pulse. A man is brought into the emergency room after a car accident, The nurse can palpate a femoral pulse but not one in the posterior tibia. Describe a possible injury. 45 LAB 5 Cardiovascular Physiology

Answer 1

Answers -

3. a - If the cuff size is wrong size it could give a reading that is too high or low.

3. b - large cuff has given the correct readings as we need take the measurements with the right cuff, right cuff for body builders with biceps circumference larger than 33cm is Large Cuff. See below cuff measurements

1. Measurement - Cm

17-22 - Small Cuff

22-32 - Medium cuff

32-42 - Large Cuff

4. The patient feels uncomfortable and painful. a tight cuff will inflate to a higher blood pressure and wrong reading will be recorded.

5. Usually the sphygmomanometer is inflated to 200mm Hg to check Arterial blood pressure measurement.

in this case when the cuff was inflated to 200mm Hg the artery was completely blocked and the pressure was then gradually lowered when pressure dropped below a certain threshold the blood was resumed. The turbulent flow during the resumption allows two methods to measure blood pressure

1. Palpatory method

2.Auscultatory Method

In palpatory method, records the pressure at which the subject feels the first pulse in the artery, the detected pulse is systolic pressure

In Auscultatory method the pulse is detected via a stethoscope placed in the ante cubical fossa over the brachial artery , when the cuff pressure is higher than the systolic pressure no sound is to be heard the pressure at which the first sound is heard is systolic pressure and the pressure at which sound disappears is diastolic pressure

5. The most common injury is tibial shaft injury In turn causes injury to the posterior tibial artery
