Respiratory Assessment Flashcards
Upper respiratory tract
Nasal Cavity
Oral Cavity
Pharynx
Larynx
Lower respiratory tract
Trachea
Left and Right lung
pericardium
diaphragm
Diaphragm
a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest.
Muscles of inspiration/expiration
intercostals -between the ribs
Scalenes –up by the neck
Cells of the respiratory system
goblet cell
submucosal gland
secretory cell
pulmonary arteriole
flow of oxygen depleted blood that has returned to the heart
Pulmonary venule
flow of freshly oxygenated blood back to the heart
Beta 2 simtulation
leads to bronchodilation –> open airway
ACh blocker
leads to bronchodilation –> open airways
Functioning respiratory system relies on (3 things)
Alveolar ventilation, pulmonary perfusion, gas exchange
Restrictive diseases
Inability to effectively breathe in: Interstitial lung disease Infiltrative lung disease Disorders of pleura or chest wall Surgical resection of lung Misc: pregnancy, obesity, ascites
Obstructive diseases
inability to effectively breathe out:
Reduced FEV1/FVC ratio to less than 70%
Asthma
COPD
Pathophysiology of asthma
contracted smooth muscle
inflammation and swelling
excess muscus
decreased lumen diameter
Pathophysiology of COPD
walls of alveoli destroyed
bronchioles lose shape and are clogged with mucus
Pulmonary Embolism
Blood clot
Often forms in leg and migrates to lung
Occludes blood vessel in lung
Prevents effective gas exchange
Acute cough
3 weeks or less
Sub-acute cough
3-8 weeks
Chronic cough
8 weeks or longer
