Correlation Between Breath-Hold Time and Maximal Inspiratory Pressure in Healthy Adults: A Cross-Sectional Study

Abstract Background: Inspiratory muscle strength is measured in terms of maximal pressure generated at mouth during inspiration. These are measured using devices which are either costlier or not easily available due to lack of knowledge in India. Even an alternative to identify these are present in form of a reference equation. But these cannot be applied to patients with neurological or respiratory disease as they are age and anthropometry based. Thus, the present study focused to find the correlation of already known BHT with MIP.
Methodology: 150 healthy volunteers (40-65years) were screened for their breath hold time (BHT) and maximal inspiratory pressure (MIP) using an aneroid manometer. The tests were performed in sitting upright position. The participants included in the study were healthy without any diagnosed respiratory as well as neurological disease. The smokers and tobacco chewers were excluded.
Results: 75 males and 75 females with a mean age of 57.29 ± 6.93, an average height being 162.23 ± 4.72 and mean weight was 65.59 ± 5.93 respectively were enrolled in the study. The MIP with Device was 78.67 ± 11.60. The BHT was of 35.02 ± 3.98. On Pearson’s correlation test, a significant positive correlation was found between MIP and BHT (r=0.462, p=0.000).
Conclusion: A positive correlation between the breath hold time and the maximal inspiratory pressure is suggestive of BHT to be used as an alternative to assess the MIP for diagnosing inspiratory muscle strength.
