Position Therapy

Question 1

Definition

Answer 1

Positioning therapy can help match ventilation & perfusion through the redistribution of oxygen & blood flow in the lungs, which improves gas exchange
> the least damaged portions of lungs receive preferential blood flow, resulting in less V/Q mismatch

Question 2

Prone Positioning

Answer 2

• Turning the pt completely over onto stomach, face down
• Used to improve oxygenation in pts w/ ARDS
• Can be used to facilitate the mobilization of secretions & provide pressure relief

Question 3

Why Prone for ARDS

Answer 3

Dependent lung areas are more heavily damaged than nondependent lung areas. Turning the pt to prone improves perfusion to less damaged areas of lungs, improves V/Q match, & dcrs intrapulmonary shunting

Question 4

Prone Position - Contradications

Answer 4

• Pts w/ incrd intracranial pressure
• Hemodynamic instability
• Spinal cord injuries
• Abdominal surgery

Question 5

Rotation Therapy

Answer 5

Improve oxygenation through better matching of ventilation to perfusion & to prevent pulmonary complications associated w/ bed rest & mechanical ventilation

Question 6

Continuous Lateral Rotation Therapy (CLRT)

Answer 6

• Pt is continuously turned from side to side w/ a rotation of 40 degrees or greater/less than
  > Kinetic Bed: the entire platform of the bed rotates
  > Oscillation Bed: the mattress inflates & deflates to provide rotation
