PhysioEx Lab ReportExercise 7: Respiratory System Mechanics Activity 2: Comparative Spirometry Name: Brianna Jackie Alison Jim Date: 2 November 2019 Session ID: session-829497cc-2bcf-0ac3-8ec3-b5ea9788deeb Pre-lab Quiz ResultsYou scored 100% by answering 5 out of 5 questions correctly.Experiment ResultsPredict QuestionsA normal resting tidal volume is expected to be aroundYou correctly answered: 500 ml.1Which respiratory process is impaired the most by emphysema?You correctly answered: expiration.2During an asthma attackYou correctly answered: inspiration and expiration are impaired.3During moderate aerobic exercise, which respiratory variable increases the most?You correctly answered: tidal volume.4Inhaler medications for an asthma patient are designed toYou correctly answered: dilate the patient's bronchioles.5Predict Question 1: With emphysema, there is a significant loss of elastic recoil in the lungtissue and a noticeable, exhausting muscular effort is required for each expiration.Inspiration actually becomes easier because the lung is now overly compliant. Using the spirogram, calculate the lung value most affected by the emphysema condition.Your answer: FEV (%).11Predict Question 2: During an acute asthma attack, airway resistance is significantlyincreased by (1) increased thick mucous secretions and (2) airway smooth muscle spasms. 2
Stop & Think QuestionsTo which lung value in the spirogram would you see the greatest change in a patientsuffering from an acute asthma attack?
