Question
To determine the possible obstruction of the airway, a FEV may be measured using a spirometer. Under normal circumstances, a healthy adult can expel 75% to 85% of the vital capacity in 1.0 second (FEV1). Predict how this would change in a person who has asthma and explain the reason why.

His oxygen saturation is 87% on room air. Mr. Yazdani does not appear to be in any distress and denies having any pain or shortness of breath.

- Use the oxyhemoglobin dissociation curve to determine hemoglobin saturation/O2 content at various pO2 and/or pH levels.arrow_forwardWhy do we use FEV1/FVC which is a measure of exhalation rate in pulmonary function testing instead of rate of inhalation?arrow_forwardSpirometry and lung volumes may be two PFTs that you have heard of. They help to diagnose obstructive or restrictive lung disease, monitor disease progression, and check whether treatments are effective. Understanding the different volumes and capacities associated with lung function will help you to better understand PFTs, respiratory disease and treatment for your patients. Lung volumes include tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). The various lung capacities include inspiratory capacity (IC), vital capacity (VC), functional residual capacity (FRC), and total lung capacity (TLC). choose 3 different lung volumes or lung capacities to explain in your own words. research a chronic lung disease (such as asthma, COPD, emphysema, fibrosis, etc) and explain how it affects specific lung volumes and/or capacities.arrow_forward
- Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.arrow_forwardAsthma is a common obstructive disease of the airways of the lungs, which can be diagnosed using the pulmonary function test, spirometry. Which of the following statements is most likely to indicate a patient with an obstructive pulmonary disorder? Spirometry test results indicating an increased forced vital capacity. Spirometry test results indicating a forced expiratory volume of 85% compared to predicted values. Spirometry test results indicating an FVC/FEV1 ratio of 0.9. Spirometry test results indicating a forced expiratory volume of 72% compared to predicted values.arrow_forwardWhat type of artificial tracheal airway should be used for the following clinical situations? If more than one option is indicated, include all appropriate choices with an explanation. A.
