Methods <ul><li>You will take BP during rest and exercise, remember to always keep the arm at heart level!! </li></ul><ul><li>You need to palpate the HR by using the radial artery and take a 15 sec count and multiply that by 4 to get a minute reading </li></ul><ul><li>The subject will pedal for 3 minutes at 50 rpm with a resistance between 1.5 kp – 2.5 kp depending on their activity level </li></ul><ul><li>When taking the BP during exercise make sure the subject continues to pedal </li></ul>
Methods: BP at rest Remember: must keep the arm at heart level at all times!! The tester must stabilize the arm while taking the BP
Methods: BP during exercise The subject must continue to pedal while the tester takes the BP, also stabilize the arm (as shown)
Using the stethoscope Most importantly remove sweatshirt or pull sleeves Up so you have direct skin contact, so you can hear The heart properly 1. Make sure the ear pieces face forward and down Before placing the ears (this is so it follows the Eustachian tubes in the ear 2. Tap on the stethoscope head to make sure you can Hear noise (do lightly because it can be loud) 3. Place over the brachial artery and be sure you can Hear the heart.
How to take blood pressure (BP) Place the sphyg on the subject’s arm with the cuff belly covering at least 80% of the arm for proper reading. Place the artery symbol above the brachial artery (this is where you are going to place the head of the stethoscope You want to make sure the valve is open when inflating the cuff (this is done by turning the valve counter-clockwise) inflate up to between 180-200 mmHg and then you want to slowly release the air, the first sound you hear is the systolic BP and the 5 th (last sound) is diastolic. Be sure to release all air once you obtained the BP reading.
