Fig. 1From: Effect of averaging time and respiratory pause time on the measurement of acoustic respiration rate monitoringApnea detection time. Box plots show the median, 25th and 75th percentiles (box boundaries), and the minimum and maximum values (whiskers). Outliers from 1.5 to 3 times larger than the box size are represented by small circles, and outliers over 3 times larger than the box size are represented by black stars. *p < 0.001Back to article page
