The study is a prospective experimental study on adult patients admitted to the Critical Care Department in Qasr Al-Ainy. This study is conducted prospectively to assess the efficiency of trigger sensitivity adjustment on patients with ventilator-induced diaphragmatic dysfunction (VIDD).

The study is a prospective experimental study on adult patients admitted to the Critical Care Department in Qasr Al-Ainy. This study is conducted prospectively to assess the efficiency of trigger sensitivity adjustment on patients with ventilator-induced diaphragmatic dysfunction (VIDD).1. Flow Trigger: This type of trigger responds to the gas flow during inspiration. A flow trigger measures the rate of change of flow as the patient begins to inhale. When the flow reaches a certain threshold, the ventilator is triggered to deliver a breath.

1. Laboratory investigations: Arterial blood gases (ABG):- (PH, PCO2, HCO3, and PO2) after the session.
2. Ventilator Parameters:( a) Minute Ventilation, b) Tidal Volume, c) Rapid Shallow breathing index, d) Negative Inspiratory Force (NIF) will be measured pre and post-treatment

Inclusion Criteria:

• Patients who had undergone MV for 48 hours or more in a controlled mode.
• Patients could not generate maximum inspiratory pressure of more than 15 mbar
• Patients had diaphragmatic excursion less than 3 cm. (normal level from 3 to 5 cm.)(It can increase in a condition person to 7-8 cm).
• Patients had a diaphragmatic thickness fraction of less than 30%

Exclusion Criteria:

• Patients with comorbidities interfering and compromising weaning like cardiac arrhythmia, pericardial effusion, congestive heart failure, or unstable acute coronary syndrome.
• Patients who had inadequate training performance of the inspiratory muscle such as those having myopathy or neuropathy.
• Patients hemodynamically unstable.
• Patients who had a major neurological deficit.
• Sedated Patients.

After publication

Our Study was performed on sixty patients with VIDD from both genders. All patients will be referred by a physician. All patients were randomly assigned into two groups equal in number
