Respiratory vital capacity
WebFeb 28, 2024 · Introduction: Respiratory function is a critical predictor of survival in amyotrophic lateral sclerosis (ALS). We aimed to determine if slow vital capacity (SVC) is a predictor of functional loss in ALS as compared to forced vital capacity (FVC).Methods: Consecutive ALS patients in whom respiratory tests were performed at baseline and 6 … WebVital Capacity. Vital capacity (VC) is easily measured with spirometry; decreases in VC point to respiratory muscle weakness. The VC averages approximately 50 mL/kg in normal adults. VC changes are not specific, however, and decreases may result from both inspiratory and expiratory muscle weakness and may be associated with restrictive lung and ...
