Ventilation With ASV Mode in Children

University of Lausanne Hospitals40 enrolled

Overview

ASV mode of ventilation is an automatic mode with closed-loop control used for mechanical invasive ventilation in intubated patients. It has been studied in adult patients but not in children. This interventional physiology study will include 40 children on mechanical invasive ventilation.

The objective of the study is to assess the feasibility of ASV in children and compare physiologic values on ASV mode to Pressure-Control and Pressure-Support mode of ventilation regarding the participant is on active or passive ventilation phase. Physiologic values will be monitored on different modes of ventilation in a randomized order. Each participant will be his own control regarding the different modes of ventilation. Monitoring will be done during 90 minutes for each mode of ventilation. Participant will have two different phases of ventilation. The first one is the passive phase (participant does not trigger the ventilator cycle sustainly) in which ASV and Pressure-Control Ventilation will be performed in a randomized order. The second phase will be the active ventilation phase (participant does trigger the ventilator cycle sustainly) in which ASV and Pressure-Support Ventilation will be performed in a randomized order.
