A severe restrictive ventilatory defect is a condition characterized by a significant reduction in lung volume, leading to impaired respiratory function. This defect is often identified through pulmonary function tests, which show decreased forced vital capacity (FVC) and total lung capacity (TLC), while the airflow rates may remain normal. Common causes include conditions like pulmonary fibrosis, neuromuscular disorders, and chest wall abnormalities. Patients typically experience symptoms such as shortness of breath and reduced exercise tolerance.

What are Two diseases associated with an obstructive ventilatory defect?
Two diseases associated with an obstructive ventilatory defect are chronic obstructive pulmonary disease (COPD) and asthma. In COPD, the airways become narrow due to inflammation and damage to the lungs, making it difficult to exhale fully. Asthma involves reversible airway obstruction and increased sensitivity to triggers, leading to symptoms like wheezing, coughing, and shortness of breath.
