ADVERSE EVENTS
The median tidal volumes for passive orthostasis and the sitting position were
436mL (IQR 395 - 507) and 435mL (IQR 380 - 480), respectively (p = 0.47). The
mean respiratory rates for passive orthostasis and the sitting position were
24.7 (SD 6.1) and 24.2 (SD 6.0), respectively (MD -0.47; 95%CI - 4.1 - 3.1; p =
0.78). The median minute volumes for passive orthostasis and the sitting
position were 10.3L/minute (IQR 8.7 - 12.5) and 11.1L/minute (IQR 8.4-12.2),
respectively (p = 0.42). There was no difference in the median number of
professionals required to perform the passive orthostasis and sitting position
protocols (passive orthostasis: 3.0; IQR 3 - 3; sitting position: 3.0; IQR 3 -
3.2; p = 0.40) (At the time the protocol was performed, four adverse events (11%) occurred
related to the safety of the interventions. One episode of tachycardia occurred
during passive orthostasis and three episodes of hypotension occurred (two
during passive orthostasis and one while in the sitting position). The number of
patients who experienced adverse events did not differ significantly between
protocols (p = 0.99) (
