Pulmonary Rehab Flashcards
What makes up the Upper and Lower Respiratory tracts?
- Upper
- Nasal + Oral cavity, larynx, pharynx
- Warms, humidifies, filters inspired air (1st line of pulmonary immune defense)
- Mucociliary escalator - lines conducting airways ( 2nd line of immune defense)
- Lower
- Trachea, bronchi, bronchioles, and alveoli
- Immune cells (macrophages neutrophils) complete pulmonary defense
which side of the lung is more likely to be a site of aspiration?
Right
mainstem bronchus is more aligned vertically

List normal values for Arterial Blood Gases
- PaO2 → greater than 80 mmHg
- PaCO2 → 35-45 mmHg
- pH → 7.35-7.45
- HCO3 → 22-26
List some common respiratory dysfunction terms
- Air trapping
- Bronchospasm
- Consolidation
- Hyperinflation
- Hypoxemia
- Hypoxia
- Respiratory distress
what is air trapping?
retention of gas in lungs as a result of partial or complete airway obstruction
what is consolidation?
transudate, exudate, or tissue replacing alveolar air
what is hyperinflation?
overinflation of the lungs at resting volume as a result of air trapping
what is hypoxemia?
a low level of oxygen in the blood, usually a PaO2 less than 60-80 mmHg
what is hypoxia?
a low level of oxygen in the tissues available for cell metabolism
what is respiratory distress?
the acute or insidious onset of dyspnea, respiratory muscle fatigue, abnormal respiratory pattern and rate, anxiety, and cyanosis related to inadequate gas exchange, the clinical presentation that usually precedes respiratory failure

Describe ARDS
- this is acute inflammation of the lungs
- associated w/many conditions

- variable latent pulmonary sequale → from no impairments to mild exertional dyspnea to mixed obstructive-restrictive abnormalities
- Prone positioning in the ICU helps
what are some conditions associated w/ARDS?
- aspiration
- drug toxicity
- inhalation injury
- pulmonary trauama,
- shock
- systemic infections
- muli-organ failure
how does prone positioning in the ICU assist with ARDS?
facilitates:
- improved aeration to dorsal lung segments
- improved V/Q mismatch
- secretion draining
