o Diffusion / perfusion Systemic circulation Anemia- decreased hemoglobin and hematocrit. When someone is bleeding internally or externally. The main 3 processes- ventilation, gas exchange, & perfusion Volumes o PFT- pulmonary function test- spirometry o Titer volume- total amount of volume with each inspiration and expiration. 500 mL o Residual Volume- the leftover volume Obstructive disorders- for ex- pneumonia. Their residual volume is high. Eupnea- normal breathing- rate- 12-20 Respiratory problems o Signs and symptoms Dyspnea- Shortness of breath, difficulty breathing (your body is requiring more oxygen) Paroxysmal nocturnal dyspnea Orthopnea- lying down position is difficult to breathe Like people w pulmonary edema, Apnea- absent of breathing Sneezing - allergies, sick, upper airway obstruction, influenza Coughing- congestion, sick, Sputum- phlegm, you ask patient the amount, color, consistency, Thick consistency- maybe infection o If it is green, tan – infection. So you send for a culture o Blood- cancer, TB, inflammation, irritant. Hemoptysis – blood when coughing
