Figure 5From: Sleep continuity: a new metric to quantify disrupted hypnograms in non-sedated intensive care unit patientsEffect of NIV on sleep continuity. Sleep time spent in sleep bouts, short naps and long naps during NIV and spontaneous breathing. Average sleep time (expressed as % of total sleep time) spent in sleep bouts lasting less than 10Â minutes, short naps (10 to 30Â minutes) and long naps (>30Â minutes) during NIV (white boxes) and during spontaneous breathing (SB) (gray boxes) in 24 patients. Bottom and top of boxes are 25th and 75th percentiles, respectively, middle lines are median, lower and upper whiskers are 10th and 90th percentile, respectively; * P <0.05, Wilcoxon signed Rank Test. NIV, non-invasive ventilation.Back to article page
