Instrumentation and valid measurement of esophageal pressure
Abstract
The use of an esophageal manometry as an estimate of pleural pressure is well known in the research field. It provides relevant information in every stage of mechanical ventilation and spontaneous ventilation. However, the use of an esophageal manometry is rare in clinical practice due to limited equipment available for signal integration, technical difficulties for instrumentation and data validity, and expertise for proper signal interpretation. This study, for the purpose of overcoming barriers, describes the placement of a manometry catheter and strategies to validate signal quality.
