Q

Physiologic effects of immobilization

A

-Muscular: decreased strength, atrophy, less joint mobility
-Skeletal: bone demineralization, neg Ca balance
-CV: orthostatic intolerance, more heart workload, thrombus
-Respiratory: decreased effort, less mvmt of secretions
-GI: decreased motility, risk for aspiration
-Renal: renal stasis, renal calculi
-Metabolism: decreased rate and stress hormones
-Skin: decreased circulation, risk for ischemia
-Urinary: difficulty voiding, retention
-Neuro: loss of innervation
-Psych: diminished stimuli, altered perception of self, increased neg feelings, developmental regression
