What are the causes of respiratory acidosis?
- damage to the medulla

- wheezing/stridor
definition: high-pitched noise caused by a partial obstruction of the airway
wheezing
definition: high-pitched sound associated w/ obstruction of the larynx or trachea
stridor
How can wheezing be resolved?
- opening the airway
- narrowing the airway
What are the primary pulmonary pain patterns?
- substernal/chest region over the involved lung
- side or back
What are the secondary pain patterns that radiate with pulmonary diseases?
neck, upper trap, costal margins, t-spine, scapula/shoulder
definition: Pain that refers to neck/ant chest (same level as irritation)
tracheobronchial
Explain what pleural pain feels like.
sharp and localized that is aggravated with any respiratory movement
What eases pleuritic pain?
auto-splinting –> tucking in the arm and laying on the affected side
