Double Triggering Asynchrony in Mechanically Ventilated Patients.

Sensitivity of Diaphragmatic Ultrasonography in Detecting Double Triggering Asynchrony in Mechanically Ventilated ICU Patients.

This observational study examined double triggering asynchrony in28ICU patients on mechanical ventilation. Researchers collected data on patient characteristics, health conditions, and outcomes to understand how this problem affects critically ill patients. Findings may help improve ventilator care in intensive care units.

Inclusion Criteria:

• Adult ICU patients aged ≥18 years receiving invasive mechanical ventilation
• Documented double triggering asynchrony on ventilator waveform analysis.

Exclusion Criteria:

• Patients with contraindications to diaphragmatic ultrasound, including thoracic or abdominal surgery.
• Patients with known diseases affecting diaphragmatic function, such as Duchenne muscular dystrophy (DMD) or myasthenia gravis (MG).
• Patients with advanced chronic liver disease (Child-Pugh class C)
• Patients with chronic increased intra-abdominal pressure.
• Patients with moderate to massive pleural effusion.
• Patient or legal guardian refusal to participate in the study.
