What does systolic BP measure | show 🗑
|
||||
show | The blood pressure while the heart is relaxed
🗑
|
||||
show | At a rate of 8-12 mm Hg per metabolic equivalent in a linear progression. And ceases to increase with sustained activity
🗑
|
||||
If systolic BP doesn't increase with increased workload what can this indicate? | show 🗑
|
||||
show | 10 mm Hg
🗑
|
||||
show | If the systolic pressure exceeds 210 mm Hg or if the diastolic exceeds 110 mm Hg
🗑
|
||||
show | Its the difference between systolic and diastolic BP. It generally increases in direct proportion to the intensity of exercise
🗑
|
||||
What happens with systolic and diastolic BP during exercise | show 🗑
|

What can excessive pulse Pressure indicate? | show 🗑
|
||||
Normally how much higher is systolic BP in the legs than in the arms(brachial artery) | show 🗑
|
||||
BP readings that are lower in the legs as compared to the arms are abnormal and may indicate what? | show 🗑
|
||||
show | The same amount of blood fills the ventricles but the pumping mechanism is less effective and the body compensates by increasing BP to attempt homeostasis
🗑
|
||||
During exercise testing, a systolic BP that doesnt increase or decrease with increasing workloads may signal what | show 🗑
|
||||
As a general guideline, the 3 minute post exercise systolic BP should be what % less than at its peak | show 🗑
|
||||
show | Avoid applying BP cuff above the infusion site, grasp IV line pole so the infusion site is at heart level', avoid activities that require the site to be above the level of the heart for prolonged periods of time, avoid disturbing the site during exercise

||||
Chest tube precaution (3) | show 🗑
|
