Overview
This is a multicentre prospective cohort trial in adult and pediatric ICU patients. The investigators will measure the effect of a patient's inspiratory effort during mechanical ventilation on the lungs and diaphragm. The investigators will daily (for a maximum of 8 days) measure esophageal pressures with a balloon catheter to quantify inspiratory effort and respiratory muscle function, and perform daily ultrasound measurements of the diaphragm and the lungs. The investigators hypothesize that a small inspiratory effort will result in the preservation of diaphragm function and have no adverse effect on lung function.
Interventions
- Device Placement of nasogastric balloon
A nasogastric balloon catheter will be inserted after inclusion. This will be a NutriVent (Sidam S.R.L., Mirandola, Italy) for patients \>40kg, and a SmartCath Esophageal pressure catheter (Vyaire/Carefusion) for patients \<40kg. This placement is similar to a standard nasogastric tube placement, which is a common procedure in an ICU. Potential minor side effects include a nosebleed, sore throat and erosion of the nose where the tube is anchored. All patients will receive this intervention. When
