Rehab for the Patient with Respiratory Failure Flashcards

1
Q

3 principles of rehab?

A
  1. Early mobilization of the patient
  2. Mobilization can precede ventilator weaning
  3. Increased strength = better vent weaning

Q

O2 delivery systems (3)

A
  1. Nasal cannula: 1-6 L/min
  2. Pendant Oxymizer: 6-15 L/min
  3. Bipap/CPAP: Continuous Positive Airway Pressure (non-invasive and used for sleep apnea

Q

CPAP

A

patient initiates every breath & gives pressure to help

17
Q

Metabolic encephalopathy

A

delirium from electrolyte imbalances

18
Q

Reasons for tracheostomies

A

a. need for ventilation > 2 weeks
b. inability to swallow
c. blockage of airway
d. obstructive sleep apnea
e. frequent suctioning needed due to ineffective cough

19
Q

3 types of tracheostemies

A
  1. cuffed
  2. uncuffed
  3. fenestrated
20
Q

Cuffed tracheostemy

A
    • holds the trach in place & prevents air flow to nose & mouth
    • if the outer bag is inflated, the cuff is inflated
21
Q

Uncuffed tracheostemy

A

– allows air flow over vocal cords - patient can talk

22
Q

Fenestrated tracheostemy

A
    • allows patient to talk

- - often promote increased scar tissue

23
Q

Positioning of trach

A
  1. the trach does NOT interfere with the passage of food
  2. the trach is below the vocal cords
  3. the cuff holds the trach in place
  4. the cuff prevents air passing up thru vocal cords
24
Q

Passy-Muir Valves

A

cuffless or deflated cuff w/ valve allows expired air to flow over vocal folds; but inspired air comes thru trach
