Post COVID-19, Single Breath Count Test (SBCT), Peak Expiratory Flow Rate (PEFR)Abstract
BACKGROUND: The utilization of spirometry has garnered significant attention recently due to its potential role in transmitting COVID-19. There is a critical need for a straightforward bedside assessment capable of accurately measuring respiratory function without relying on equipment and minimizing the risk of airborne transmission.
AIMS: To know the correlation between Single Breath Count Test (SBCT) values and Peak Expiratory Flow Rate (PEFR) values in adult patients recovering from COVID-19.
METHOD: This study presents a cross-sectional design with consecutive subject recruitment. The SBCT was administered using a metronome, while PEFR was measured using a Mini Wright Peak Flow Meter on a sample of 38 participants, comprising 18 men and 20 women.
RESULT: Statistical analysis using Pearson’s parametric correlation test revealed a significant relationship between SBCT and PEFR (p < 0.05), with a moderate positive correlation observed (r = 0.516).
CONCLUSION: This research demonstrates a significant, moderate positive correlation between SBCT and PEFR in adult post-COVID-19 patients, indicating that higher SBCT values correspond to higher PEFR measurements.
