Diaphragm-Protective Ventilation: Is It Time to Give the Diaphragm a Break, Just Not Too Much?

Video Transcription

Video Summary

The presentation explores the management and complications of Acute Respiratory Distress Syndrome (ARDS), particularly focusing on diaphragmatic dysfunction due to mechanical ventilation. A typical ARDS case is discussed, highlighting the challenges of prolonged ventilatory support. The speaker identifies ventilator-induced diaphragmatic dysfunction, also known as myotrauma, where the diaphragmatic muscle weakens due to mechanical ventilation. Several types of myotrauma are explained: over-assistance leading to disuse atrophy, under-assistance causing excessive effort, eccentric contraction causing muscle damage, and end-expiratory shortening from PEEP. Evaluations using ultrasound and other technologies can measure diaphragmatic function. For optimal management, it's crucial to balance lung and diaphragm protection through customized ventilatory and sedation management, incorporating new techniques and continuous monitoring. This approach may mitigate complications and improve patient outcomes in mechanical ventilation contexts.
