upper respiratory tract nose, mouth, pharynx, epiglottis, larynx, trachea
lower respiratory tract bronchi, bronchioles, alveolar ducts, alveoli
right -3
lung lobes
left - 2
protein released to decrease surface tension in alveoli
surfactant
naturally release when sighing
collapsed alveoli
atelectasis
-coughing, deep breathing, early ambulation, IS
dead space
trachea and bronchi
VD no gas exchange
about 150ml per breath
included in tidal volume
Tidal volume
amount of air in respiratory tract
Vt
about 450-750ml per breath vary with body size
about 500ml per breath in general
-gas exchange
-back and forth to the heart
Pulmonary circulation -artery- deoxygenated blood from right ventricle
-capillaries- exchange gases at alveoli
-veins - return oxygenated blood to left atrium
-feeding blood supply to bronchial and lung tissue
Bronchial circulation -arteries- oxygen to bronchi and lung tissues
-azygos vein - deoxygenated blood to superior vena cava
Ventilation actual inhalation and exhalation
partial pressure of oxygen in arterial blood(PaO2); normal
oxygen dissolved in plasma
80 to 100mmHg
, oxygen bound to hemoglobin 1/9
