Practice Variation in Spontaneous Breathing Trial Performance and Reporting

Figure 3

Distribution of Richmond Agitation Scale Score (RASS) ranges overall and across sites. The large pie graph in this figure depicts the overall distribution in RASS scores from all spontaneous breathing trials (SBTs) with available data for sedation. The series of small pie graphs represent the centre-specific distributions, allowing comparison across sites. Values expressed as % proportion of SBTs. values represent the number of SBTs at each site with available data.
