Week 9

Question 1

List 4 general problems that can be targeted with Positioning

Answer 1

1. V/Q mismatching
2. Improve lung volumes
3. clear secretions
4. Decrease WOB

Question 2

A patient is side-lying, which lung has the greatest potential for expansion and therefore ventilation

Answer 2

Lowermost lung

Question 3

In unilateral lung disease, should the healthier lung be placed upper or lowermost when side-lying

Answer 3

Healthy = Lower most

Question 4

Why might right-sided side-lying be considered in a patient with global bilateral lung disease

Answer 4

The right lung has greater surface area and volume due to the position of the heart

Question 5

Where does optimal ventilation occur in a patient that is side-lying, but mechanically ventilated

Answer 5

the upper lung (mechanical positive pressure follows the path of least resistance)

Question 6

Where does optimal perfusion occur in a patient that is side-lying, but mechanically ventilated

Answer 6

The lower lung (perfusion will still follow gravity in this case)

Question 7

What side-lying position should be used for an infant with R) sided unilateral lung disease

Answer 7

L) side-lying (good lung upper most)

Question 8

A pt has had a pneumonectomy on the R) side, what side-lying position is optimal

Answer 8

Side-lying on R) side

Question 9

What position may help WOB

Answer 9

Forward lean sitting
