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...

3) Choose appreciate letter for conditions below and explain: a) Emphysema: Patients with emphysema have lungs with reduced elastic recoil, leading to an increase in resting lung volume or functional residual capacity (FRC). FRC consists of two sub-volumes called a. Tidal volume and residual volume b. Inspiratory reserve volume and expiratory reserve volume c. Tidal volume and expiratory reserve volume d. Expiratory reserve volume and residual volume It is sufficient that you give the correct letter answer here b) Spirometry...

Given the following, calculate expiratory reserve volume TV = 450,000 microL VC = 6.2 L IRV = 1700 mL How does vital capacity normally vary with age? How does residual volume normally vary with age? How does residual volume and vital capacity vary with height? During an asthma attack, intense bronchoconstriction can occur. How would this affect expiratory reserve volume? What respiratory muscle is impaired by pregnancy? Explain how. In obstructive lung diseases expiration is difficult. How would this affect...

A 150 lb., 62-year-old man had a chronic productive cough, exertional dyspnea, mild cyanosis, and marked slowing of forced expiration. Calculate the tidal volume (TV) for this person before and after the bronchodilator therapy. His pulmonary function and laboratory tests follow: Frequency 16 breaths/min Alveolar ventilation 4.2 L/min Vital capacity (VC) 2.2 L Functional residual capacity (FRC) 4.0 L Total lung capacity (TLC) 5.2 L Maximum inspiratory flow rate 250 L/min Maximum expiratory flow rate 20 L/min PaO2 62 mm...

A 17 year old student complained of wheezing and shortness of breath, especially at night. He was known to be allergic to feathers and house dust. Physical examination revealed inspiratory and expiratory rales and hyperresonance with percussion of the chest but no cyanosis. Radiologic examination suggested over-inflation of the lungs, but no localized disease. The following laboratory and pulmonary function test values were obtained: Vital Capacity 2,800 ml (decreased) Functional Residual Capacity 4,420 ml (increased) Total Lung Capacity 7,050 ml...
