Residual volume is the volume of air that remains in lungs after full expiration.
forced expiratory volume is quantity of air that can be exhaled during a forced breath.
chronic obstructive pulmonary disease is an inflammatory lung disease in which there is airflow obstruction .
Forced expiratory volume is reduced in copd as the person is unable to forcibly expire and remove air from lungs. Hence residual volume increases.

B. Your second patient is 64 years old with chronic obstructive pulmonary disease (COPD). He caught a cold a week ago and presents to the clinic with areen sputum and increased shortness of breath. He had a fever at the beginning of the cold. but does not have a fever today. Current medications are Symbicort (budesonide/formoterol) and lisinopril. On examination, he is afebrile, with respiratory rate 18, heart rate 104, blood pressure 135/70 mm Hg, and SaO2 93 %. Lung...

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...

During a routine annual physical exam, a 57 year-old man is
given a normal pulmonary function test. He has never smoked but had
a possible brief exposure to asbestos in his youth. The results of
his pulmonary function test are below including the flow-volume
loop. The predicted values in the table below are the values that
would be expected in a man of his age, height, weight etc. They are
to be considered normal values for this individual. In the...

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...

Group 3: Topic 6 – 17-year-old girl case study A 17-year-old student has experienced reversible, periodic attacks of chest tightness with coughing, wheezing, and hyperpnea. She states that expiration is more difficult than inspiration. She is most comfortable sitting forward with arms leaning on some support. X-rays revealed mild overinflation of the chest. Results from laboratory and pulmonary function tests are as follows: Frequency 20 breaths/min Forced Vital capacity (FVC) 2.9 L FEV1.0 1.4 L FEV1.0/FVC Functional residual capacity (FRC)...

Mr. S. is a retired 69-year-old county attorney who was on a buying trip with his wife looking for old, classic cars in the high, mountainous country of Colorado when he became extremely short of breath, much more than usual. His alarmed wife took him to a multispecialty medical clinic for evaluation. Upon admission, Mr. S. was restless and dyspneic. His past history revealed a habit of smoking two packs of cigarettes a day for 45 years (90 pack years)....
