Rehab for the Patient with Respiratory Failure Flashcards
3 principles of rehab?
- Early mobilization of the patient
- Mobilization can precede ventilator weaning
- Increased strength = better vent weaning
Causes of respiratory failure (7)
a. restrictive airway disease
b. neuromuscular disorders
c. metabolic issues such as kidney failure decreasing blood pH
d. decreased perfusion (PE)
e. reactive airway disease
f. obstructive airway disease
g. ventilatory failure
Severe hypoxemia
PaO2
Hypercapnia
PaO2 > 40 mmHg
Normal PaO2
80-100 mmHg
Normal PaCO2
35-45 mmHg
Normal pH
7.35-7.45
Respiratory acidosis
higher CO2 with lower pH
Pulse oximetry gives you what information?
% of O2 in the blood
Signs of rising CO2
patient is combative and confused
O2 delivery systems (3)
- Nasal cannula: 1-6 L/min
- Pendant Oxymizer: 6-15 L/min
- Bipap/CPAP: Continuous Positive Airway Pressure (non-invasive and used for sleep apnea
4 modes of ventilation
- Full support
- Assisted ventilation
- Intermittent ventilation
- Continuous Positive Airway Pressure (CPAP)
Full support ventilation
gives full breath once patient initiates breath
Assisted ventilation
allows patient to control breathing rate & depth in between ventilator breaths
Intermittent ventilation
patient can spontaneously breathe in between breaths given by machine
CPAP
patient initiates every breath & gives pressure to help
Metabolic encephalopathy
delirium from electrolyte imbalances
Reasons for tracheostomies
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
3 types of tracheostemies
- cuffed
- uncuffed
- fenestrated
Cuffed tracheostemy
- holds the trach in place & prevents air flow to nose & mouth
- if the outer bag is inflated, the cuff is inflated
Uncuffed tracheostemy
– allows air flow over vocal cords - patient can talk
Fenestrated tracheostemy
- allows patient to talk
- - often promote increased scar tissue
Positioning of trach
- the trach does NOT interfere with the passage of food
- the trach is below the vocal cords
- the cuff holds the trach in place
- the cuff prevents air passing up thru vocal cords
Passy-Muir Valves
cuffless or deflated cuff w/ valve allows expired air to flow over vocal folds; but inspired air comes thru trach
