This procedure measures Forced Vital Capacity which requires a maximal inhalation and maximal, forced exhalation. FVC + Residual Volume (not measure here) is = Total Lung Volume. FEV 1.0 is the amount expired in one second. The ratio of FEV 1.0 to FVC is clinically relevant. A ratio of 80% or greater is considered normal. Less than 80% could indicate conditions such as asthma or COPD (emphysema).
What are the mechanisms involved in the biphasic response observed in forced expired volume in patients with asthma exposed to allergen challenge?
