Q

Q1
. Jamie Le is diagnosed with asthma. She is surprised to find that her total lung capacity (TLC) and residual volume are increased. Explain why the total lung capacity and residual volume couldincrease in asthmatics

A

body compensates for reduced air flow with increase air intake

Q

Q2
. Forced expiratory volume in 1 second is the amount of air exhaled in 1 second. Explain why Jamie’s FEV1 is reduced
Note: Jamie has asthma

A

Obstructive ventilation disorder, therefor the rate at which they can exhale decreases

Q

Q3. Jack Newland, aged 59 has
Pulmonary fibrosis. Pulmonary fibrosis is an example of a restrictive lung disorder. What is likely to be the difference between Jack’s total lung capacity and the total lung capacity of a patient with normal lung function?

A

Constrictive ventilation disorder, therefor the maximal lung capacity is lower than a patient of normal lung function

17
Q

Q4.Jack find out that there is an
increase in alveolar dead space. How will an increase in alveolar dead space affect his minute ventilation and alveolar ventilation?
Note: he has pulmonary fibrosis

A

Minute ventilation will not be effected as it does not take into account dead space
Alveolar ventilation will change, and negatively due to the lesser amount of air reaching the alveoli
