Abstract
Background and Objective: Pregnancy is characterized by physiological and
anatomical changes in females which lead to major changes in the respiratory system. So the
objective of this study was to compare the respiratory muscle strength of primigravidae with that
of nulligravidae in Indian population.
Methods: The total subjects were divided into two groups i.e. group A (Primigravidae group) and
B (Nulligravidae). Subjects in both the groups underwent respiratory muscle testing according to
the American Thoracic Society (ATS) or European Respiratory Society (ERS) guidelines.
