Hematologic Disorders 3 Flashcards
Special considerations for hematologic disorders: should make sure to look at changes with this
coagulation
consider these with respect to changes in coagulation in pts with hematologic disorders:
- increased risk of thrombus
- increased work for heart
- breathing
- tissue perfusion
Platelet disorders are very important to consider with respect to this! (PT)
exercise prescription
normal platelet range
150,000-400,000 per microliter of blood
PT prescription: platelet range = 40-60,000
- keep exercise in low-load (1-2#) resistance
- OK for walk, bike, ADLs
PT prescription: platelet range = 20-40,000 per microliter of blood
- low intensity
- no resistance
PT prescription: platelet range = below 10,000 per microliter of blood means the pt is at risk for
spontaneous bleed
Why must clotting precautions be taken with a pt who has splenomegaly?
Splenomegaly is usually associated with rapid destruction of blood cells
PT implications with splenomegaly
Avoid activities or positions that could traumatize abdomen or increase pressure
What can exercise and sports do with respect to blood volume and erythrocytes for pts with hematologic disorders?
- can increase blood volume (plasma) immediately
- increase erythrocytes over time
Blood doping through:
exogenous EPO
Blood doping through exogenous EPO can increase these in pts with hematologic disorders:
- blood viscosity
- thrombus formation
risky process
In general, there is a possible indication of hypovolemia any time there’s a combination of:
- systolic BP drop of 20 points or more
- Increased HR of 15 BPM or more
What is the most likely cause of hypovolemia in pts with hematologic disorders?
dehydration
What are possible causes of hypovolemia in pts with hematologic disorders?
- dehydration (most likely)
- diarrhea
- slow GI bleed
- May be normovolemic but on antihypertensives
