Assessing SB effort via a non-invasive model-based method in mechanically ventilated patients in Malaysian ICU hospital

Patients with Acute Respiratory Distress Syndrome (ARDS) required mechanical ventilation (MV) for breathing support. However, some MV patients encountered spontaneous breathing (SB) efforts while fully sedated which can obscure the true underlying respiratory mechanics of these patients. Thus, a mod...
