There were 3 devices for respiratory therapists after the study period.

Values represent mean (SD) daily messages during 5 months of the 6-month study period (154 d from Aug 29, 2005 to Jan 29, 2006) and after the study period (152 d from Jan 6, 2007 to Jun 6, 2007). Messages could be received from other devices or though the hospital e-mail system from desktop computers located at each patient's bedside. p values comparing during and after study periods are calculated using t tests.

Abbreviations: n/a = not applicable; SD = standard deviation.
