Expiratory reserve volume (ERV) is the amount of air that can be forcibly exhaled beyond a tidal exhalation. Given an initial pressure of 760 mmHg and TLC of 5 L, what will be the new pressure in your lungs when the diaphragm creates a total of 892.9 mL (ERV). Hint: V2 = 5000mL - ERV

    Joe Smith is a 69-year-old male with a 50-year history of smoking 2 packs of cigarettes a day (i.e. 100-pack-year smoking history). Over the past 5 years, he has become increasingly short of breath. At first, he noticed this only when exercising, but now he is even short of breath at rest. Over the past two years, he has had several bouts of lower respiratory tract infection treated successfully with antibiotics. His shortness of breath hasn't subsided, and his breathing...
