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 …
Impact Of Physician Education And Availability Of Parameters Regarding Esophageal Pressure And Transpulmonary Pressure On Clinical Decisions Involving Ventilator Management, Lonny Ashworth
Respiratory Therapy Faculty Publications and Presentations
Purpose: This study investigated the effects of physician education and the availability of Peso and PL data on physicians' decisions regarding ventilator management during specific simulated clinical conditions.
Materials and methods: The study was a prospective, before–after study using a case scenario–based questionnaire and a case simulator device comprising an Avea ventilator and an artificial lung and esophagus, which was connected to a Series 1101 Electronic Breathing Simulator. The 99 physicians participating in the study were provided with five simulated cases with on-time ventilator graphics without Peso and PL and completed a questionnaire on decisions they …
