Increase In Intra-Abdominal Pressure During Airway Suctioning-Induced Cough After A Successful Spontaneous Breathing Trial Is Associated With Extubation Outcome, Lonny Ashworth
Respiratory Therapy Faculty Publications and Presentations
Background: A patient’s ability to clear secretions and protect the airway with an effective cough is an important part of the pre-extubation evaluation. An increase in intra-abdominal pressure (IAP) is important in generating the flow rate necessary for a cough. This study investigated whether an increase from baseline in IAP during a coughing episode induced by routine pre-extubation airway suctioning is associated with extubation outcome after a successful spontaneous breathing trial (SBT).
Methods: Three hundred thirty-five (335) mechanically ventilated patients who passed an SBT were enrolled. Baseline IAP and peak IAP during successive suctioning-induced coughs were measured with a fluid …
