PhysioEx Lab Report Exercise 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 Results You scored 100% by answering 5 out of 5 questions correctly. Experiment Results Predict Questions A normal resting tidal volume is expected to be around You correctly answered: 500 ml. 1 Which respiratory process is impaired the most by emphysema? You correctly answered: expiration. 2 During an asthma attack You correctly answered: inspiration and expiration are impaired. 3 During moderate aerobic exercise, which respiratory variable increases the most? You correctly answered: tidal volume. 4 Inhaler medications for an asthma patient are designed to You correctly answered: dilate the patient's bronchioles. 5 Predict Question 1: With emphysema, there is a significant loss of elastic recoil in the lung tissue 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 (%). 1 1 Predict Question 2: During an acute asthma attack, airway resistance is significantly increased by (1) increased thick mucous secretions and (2) airway smooth muscle spasms. 2
