Figure 2 Comparison of the percentage of time spent in the left lateral decubitus (LLD), right lateral decubitus (RLD), and supine positions compared between patients with congestive heart failure divided dichotomously into those above and below the median values for left ventricular end-diastolic diameter (LVEDD) (62.5 mm), pulmonary capillary wedge pressure (PCWP) (11.5 mm Hg), and cardiac output (CO) (4.7 l/min). Mean (± SD) values above and below these medians were: LVEDD, 72.5 ± 6.5 vs. 57.2 ± 3.8 mm; PCWP, 19.8 ± 6 vs. 6.8 ± 3.1 mm Hg; and CO, 5.7 ± 0.8 vs. 3.8 ± 0.7 l/min. Patients with larger LVEDD, higher PCWP, and lower CO spent less time in the LLD position. No significant differences were found in time spent in the RLD or supine positions based on these dichotomous divisions. Data are nonnormally distributed (see Fig. 2.) *p < 0.05.
