Homework Answers
a. Total pulmonary ventilation = Ventilation rate x Total volume
= 14 breaths/minute x 450 ml/breath
= 6300 ml/minute
Dead space volume for human is about 150 ml
b. Alveolar ventilation rate = Ventilation rate x (Tidal volume - Dead space volume)
= 14 breaths/min x (450 ml/breath - 150 ml)
= 4200 ml/minute

The lung's vital capacity of a 6 year old girl is 2 L and her lung's tidal volume is 7 mL / kg. Her breathing rate is 30 breaths per minute and her heart rate is 80 beats per minute. Her weight is 20 kg and height is 120 cm. What is her minute respiratory volume, in liters? (do not put units in your answer).

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...

For 1 is it Respiratory Zone
or Conducting Zone
Steve thought he would see how long he could stay under water in his friends pool by using a garden hose to breath through from the surface. The hose was small and had a total volume of 250 ml. Steve had a few beers and he was relaxed with a respiratory rate of 10 breaths per minute After less that one minute Steve surfaced much to everyone's dismay. 1. The hose...

A patient has an obstruction of her right main bronchus. How would this affect the carbon dioxide levels in her right pulmonary veins? What occupies the dorsal groove between the two lungs? Given that john has a vital capacity of 4.5L and a residual volume of 1500 mL, what is his total lung capacity? (Please show your work) During expiration, pressure in the __________ is higher than pressure in the trachea. Pharynx Larynx Esophagus Bronchi Given the following, calculate expiratory...

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...

CASE STUDY A 19-year-old female college student presents to the emergency department complaining of chest tightness and dyspnea. She was cutting and trimming the lawn when these symptoms developed. Rhinorrhea and tearing began soon after she went outside and preceded the chest discomfort. Going inside did not relieve her symptoms. During the physical examination, she said, "I have had asthma since childhood, and my mother and brother also have asthma." Her respiratory rate was 30 breaths per minute, and she...
