B. Orthostatic Hypotension 1. Have the subject sit quietly for 5 minutes. 2. Record resting HR and BP. Deflate cuff but leave attached to one arm. 3. Ask the subject stand upright against the wall. It is important that they relax as much as possible (other group members should remain quiet!). 4. Record HR and BP immediately upon standing. SAFETY NOTE: It is important that other group members closely monitor the study subject and be prepared to catch them should they faint. 5. Measure HR and BP at 2 min intervals (maximum of 8 minutes). Stop the experiment if the subject begins sweating or feels light-headed. 6. At the end of the time period, have the subject sit down and rest. Record post-stress HR and BP 2 min C. Pain (optional) 1. Have the subject sit quietly for 5 minutes. 2. Record resting HR and BP. Deflate cuff but leave attached to one arm. 3. Place the plastic plate on the subjects shin with the wooden dowels facing inward. 4. Attach the supplied pressure cuff over the plate and inflate gradually until the subject reaches a pain intensity of 3 on the Wong-Baker Pain Rating Scale (below). Note the pressure on the cuff and maintain this throughout the study (do not exceed 110 mm Hg). 5. Record HR and BP at 1 minute intervals for a maximum of 3 minutes. 6. Remove assembly at 3 minutes or when subject requests. 7. Record post-stress HR and BP 2 min removal. D. Exercise Stress 1. Have the subject sit quietly for 5 minutes. 2. Record resting HR and BP. Deflate cuff but leave attached to one arm. 3. Set metronome at 98 beats/ minute. Have subject step up and down on the step-box, keeping pace with the metronome (approximately 24 steps/ min). 4. Record HR and BP at 1 minute intervals for 3 minutes. It will be necessary for a student to support the sphygmomanometer during the exercise. The experiment should be terminated if the student feels faint or out of breath.
