Therapeutic Body Positioning Flashcards
Noninvasive PT intervention that augments arterial oxygenation
Therapeutic body positioning
Goals of positioning
- reduce dyspnea
- optimize lung volumes and V/Q ratio
- Assist to clear A/W secretions
Duration of positioning is
Response dependent
Optimal position to reduce dyspnea
Sitting, leaning forward with arms on thighs
Fixating arms allows
Accessory muscles to augment ventilation
The upright position…
- Optimizes O2 transport
- prevent A/W closure
- decrease compression on heart and work
- decrease urinary stasis
- ^ A-P diameter
Supine….
- A/P is transverse
- ^ A/W closure
- ^work of breathing
- decrease VC
- risk aspiration
Sidelying…..
Kind of in the middle of standing and supine.
Which position -Augment O2 transport for pts with air flow limitation
Trendelengberg
For sidelying, which lung should be dependent and why?
Right (bigger and less compression on heart)
Trendelengberg has increase in
Dyspnea and risk of reflux
Abdomen free position (prone) enhances
Lung compliance, TV, FRC, Diaphragm
Why would u lie pt prone?
Allow post lung to ventilate
-posterior has greater surface area
Considerations for positioning
-time constraint
-manpower
-modifications when extreme position not possible
-encourage mvt.
_VITALS
Negative effects of bed rest
- decrease hydrostatic pressure
- low energy
- decrease pressure on skeleton
- psychological stress
- -contracture
- metabolism change
- DVT,
- atelectasis
- atrophy
