Filter by:The primary objective of this study is to determine whether neuromuscular electrical stimulation applied to the abdominal wall muscles in synchrony with exhalation can increase the strength of the respiratory muscles in prolonged mechanical ventilation patients.
Eligible patients will be allocated to receive propofol sedation titrated to 3 different Bispectral Index (BIS) levels in a random order. Primary hypothesis: Deepening propofol sedation — as determined by BIS — lowers esophageal pressure in critical care patients.
In this study, we want to compare two different kinds of artificial ventilation to see if one encourages faster weaning from breathing support and if one provides better sleep quality. These artificial ventilation types are: 1. Pressure support ventilation; the standard ventilation that we use for the patients in the Respiratory Acute Care Unit. Pressure support ventilation ventilators use constant air pressure to assist patients with their breathing. 2. Proportional assist ventilation; a newer way of helping people with their breathing. The air pressure provided by proportional assist ventilation ventilators varies with the size of the breath that a person takes.
The primary objective of this study is to test the hypothesis that time on the ventilator and ICU length of stay will be shorter in TAA patients given postoperative sedation with dexmedetomidine compared to those given standard sedation. Secondary endpoints are: requirement for sedatives vasoactive drugs incidence of postoperative delirium and cost analysis.
Some patients receiving mechanical ventilation have difficulty weaning off the ventilator because of physiological factors such as pre-existing lung disease, respiratory distress syndrome, and trauma among others. Allowing patients to become hypercarbic (increased blood bicarbonate level) may make it easier for these patients to be taken off the ventilator and resume breathing on their own.
