The six measurement
time-points included immediately after being admitted
to OHS-ICU (T1), one hour after admission (i.e. immediately before
the intervention; T2), immediately after the intervention (i.e.
twenty minutes after T2; T3), ten minutes after the intervention
(T4), immediately after extubation (T5), and one hour after it (T6).
The time interval between admission to OHS-ICU and extubation
was considered as the MV weaning time and was measured by
using a chronometer.
