WebbAbstract Respiratory function tests (RFTs) are commonly used as a measure of progression in ALS. This study assessed the ability of various RFTs to predict survival in ALS patients. Subjects with ALS had one or more measurements of seated and supine FVC, maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). WebbFEV1 is used to determine the severity of obstructive and restrictive disease, although the values were arbitrarily determined and are not based on evidence from patient outcomes.

Webb4 dec. 2024 · Slow vital capacity (SVC), a measure of respiratory function, declines more quickly in ALS patients who are older or have advanced disease. SVC decline correlates with slippage in other respiratory measures, time to tracheostomy, and even death. People who better maintain SVC have less risk of respiratory failure, and live longer. Webb7 feb. 2014 · Background A higher slow vital capacity (VC) compared with forced vital capacity (FVC) indicates small airway collapse and air trapping. We hypothesized that a larger difference between VC and FVC (VC-FVC) would predict impaired exercise capacity in patients with chronic obstructive pulmonary disease (COPD).

FVC is a measure of lung volume and is usually reduced in diseases that cause the lungs to be smaller. Such processes are generally termed restrictive and can include disorders of the lung parenchyma, such as pulmonary fibrosis, or of the bellows, including kyphoscoliosis, neuromuscular disease, and pleural effusion.

Although the most commonly used VC is FVC, American Thoracic Society guidelines suggest alternative VCs, for example, slow VC (SVC), may offer a more-accurate evaluation of breathing capacity.
