Final answer:
A proper 133Xe ventilation study primarily includes the measurement of lung volumes using spirometry, providing valuable information on lung compliance and resistance relevant to various lung diseases.
Step-by-step explanation:
A proper 133Xe ventilation study should include the measurement of lung volumes, specifically focusing on assessing the functional status of the lungs by examining air movement. Techniques such as spirometry are central to this process, where important measures like the forced expiratory volume (FEV) and forced vital capacity (FVC) are obtained. These measurements help in diagnosing various lung conditions, as they reveal information about the compliance and resistance of the lungs.
Compliance refers to the ability of the lungs to expand, while resistance indicates the difficulty in airflow through the bronchial tubes. A high FEV1/FVC ratio suggests stiff lungs as seen in fibrosis, while a low ratio indicates presence of obstruction characteristic of asthma. A thorough ventilation study does not typically include diffusing capacity or lung compliance as separate measures.
