17
Q
What is orthostatic hypotension, as a cardiac effect of prolonged bed rest?
A
Sitting or lying down leads to LBP
Pt is constantly lying down during bed rest
18
Q
What is thromboembolism, as a hematologic effect of prolonged bed rest?
A
Blood clot obstructs a blood vessel, causing blood to remain stuck in an area
No movement → may make it more diff. for blood to circulate
PT Imp: ankle/heel pumps may help blood flow w/ minimal mvmt
19
Q
What is ventilation-perfusion mismatch, as a respiratory effect of prolonged bed rest?
A
Lung receives O2 w/o blood flow, or blood flow w/o O2
Occurs when an airway is obstructed
20
Q
What is bowel motility, as a gastrointestinal (GI) effect of prolonged bed rest?
A
No physical movement → no bowel movement in the body
PT Imp: As soon as Pt gets up, they will need to go #2
21
Q
What is muscle weakness, as a musculoskeletal effect of prolonged bed rest?
A
Loss of muscle strength/tone, possible atrophy
Pt needs movement to keep strength
PT Imp: Pt may be weaker than they look
22
Q
What is risk of contracture, as a musculoskeletal effect of prolonged bed rest?
A
Joints get stiff w/o movement
Muscles don’t want to relax after being stretched in the same position for a long time
23
Q
What is reduced pain threshold, as a neurologic effect of prolonged bed rest?
A
Pt becomes more sensitive to a stimulus that wasn’t painful before
PT Imp: be gentle, Pt is more sensitive to pain
24
Q
What is pressure ulcer formation, as an integumentary effect of prolonged bed rest?
A
Skin & soft tissue press against hard surfaces for a while → reduces blood supply to that area → forms bedsores/pressure sores
PT Imp: be careful around red areas of skin (skin check)

Microvascular alterations
Metabolic alterations
Electrical alterations
Bioenergetic failure
32
What are factors of microvascular alterations, leading to the development of CIP & CIM?
- vasodilation (blood vessels widen)
- inc. permeability
- endoneurial edema (exc. accumulation of fluid in interstitial connective tissue of a peripheral nerve)
- hypoxemia* (lack of O2 in blood)
- extravasation (leakage of blood, lymph, or fluid from a tube into tissue)
- cytokine production (T cell, macrophage)
33
What are factors of metabolic alterations, leading to the development of CIP & CIM?
- hyperglycemia* (high blood glucose)
- hormone imbalance
- hypoalbuminemia (low albumin prod. → fluid can't remain in blood vessels)
- amino acid deficiency (lack of protein)
- activation of proteolytic pathways (break down proteins)
34
What are factors of electrical alterations, leading to the development of CIP & CIM?
- ion channel dysfunction
- cell depolarization
- cell inexcitability (can't generate action potential)
- altered Ca2+ homeostasis
- changes in excitation-contraction coupling* (rhythm can be thrown off)
35
What are factors of bioenergetic failure, leading to the development of CIP & CIM?
- antioxidant depletion (lose protection against free radicals)
- reactive O2 species (ROS) increase
- mitochondrial dysfunction (can affect other diseases)
- apoptosis* (death of cell)
36
What is the difference b/t diagnosis (Dx) vs. prognosis (Px)?
Dx is the label/explanation given for relevant signs & symptoms
Px is how well a PT thinks a Pt will do based on age, motivation, etc.
37
What is Px used for?
Prepares Pt mentally (how well they'll do, how long it'll take, difficulty of PT)
Convinces insurance that PT will benefit the Pt (or not)
38

Compare/contrast findings
Provides diff. options
39
What is the difference b/t signs vs. symptoms?
