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
