1. Sputum
1.1. Foul smell: aerobic infection
1.2. Purulent: (yellow or green- infection
1.3. Pink frothy: Pulmonary edema
1.4. Mucoid (clear, thick) : Cystic fibrosis
1.5. Rusty: Bacterial pneumonia
2. Auscultation
2.1. Vescicular
2.1.1. normal, soft rustling throughout inspiration & begining of expiration, breezy, faint, heard over chest mostly except trachea

5. V/Q ventilation perfusion ratio
5.1. (See the quick bytes section on nptehive.com)
6. ABG ANALYSIS
6.1. Steps
6.1.1. Look at pH : If normal, answer is compensated
6.1.2. Look at PaCo2: 35-45 if normal answer is Metabolic
6.1.3. Look at HCo3 (22-26) If normal answer is respiratory'
6.1.4. None of the 3 are normal ANSWER is Partially compensated
7. Lung volumes and capacities
7.1. With aging
7.1.1. Tidal volume remains same
7.1.2. Residual Volume increases
7.1.3. Vital Capacity decreases
7.1.4. Forced expiratory volume decreases
