The following questions pertain to the labs as indicated. These questions should be answered after you complete the lab and will be handed in at the next lab. These questions will help you apply the lab material to the clinical setting. Lab 2 Vital Sign Questions 1. A 32 yrs. old patient is going to be riding on a stationary bike in clinic. She is riding at 2 kp and the therapist records the following vital sign response. HR: 76 Resting Minute 2 Minute 4 Minute6 HR: 92 HR: 126 HR: 144 BP 126/64 BP 148/64 BP 154/7 BP 168/84 What is the assessment of this response? Is it normal, abnormal? What should the therapist do the next time the patient rides the bike? (1pt) A 28 yr. old man is training in the clinic to return to biking. He will be training at 70-75% of his heart rate. His resting HR is 72, What is his target HR range using the Karoven formula? (1 pt.) (show work) 2.Explanation / Answer
1. As the patient ride the bike the heart rate should be within a target zone, which is 50 to 85 per cent of the maximum heart rate.
The maximum heart rate is 220 minus age.
= 220-32 =188
The heart rate should be within 94- 160
The Blood pressure is also within the normal limits.
Before hours of the test, the patient should stop take anything by mouth.
Avoid foods that may alter the tests.
2. Age of the patient = 28 years
Training at 70-75% of his heart rate
Resting heart rate is 72
Karoven formula uses the client’s age and fitness level to determine the heart rate target zones. It is recommended for people who are experienced exercisers because of the personalized nature.
As the patients zone will be zone 2 (he is training at 70-75% of his heart rate)
The estimated maximum heart rate is 220 minus the age = 220 -28 =192
Lower target heart rate zone 1= (Maximum heart rate - Morning Resting HeartRate) * 0.7+ Morning Resting Heart Rate
= (192 -72) x0.7 +72 = 213.6 =214
Upper target heart rate = (Maximum heart rate - Morning Resting HeartRate) * 0.8 + Morning Resting Heart Rate
= (192-72) x 0.8 + 72 = 168
The heart rate range is 168 -214
70-80% of maximum heart rate (Zone 2) (Maximum heart rate - Morning Resting HeartRate) * 0.7+ Morning Resting Heart Rate
(Maximum heart rate - Morning Resting HeartRate) * 0.8 + Morning Resting Heart Rate
