Evaluation of the Diaphragm Performance During Weaning From Mechanical Ventilation

Overview: This study looks at how well the diaphragm, a large muscle that helps you breathe, works when patients are being taken off a breathing machine. If you've been on a breathing machine for at least 48 hours and are being slowly taken off it, you might be part of this study. Doctors will use a special ultrasound to see how your diaphragm is moving and how strong it is.

Who can join: Adults in the Intensive Care Unit (ICU), who have been on a breathing machine for at least two days, and are awake and alert. People with other serious health problems won't be able to join.

What happens: If you join, doctors will use an ultrasound to check your diaphragm right before you try to breathe on your own. They will compare results between different patients to see if the ultrasound can predict how well patients do without the machine.

• **Study Length:** Observational during weaning phase.
• **Visits Needed:** Only during ICU stay.
• **Risks:** Minimal, related to ultrasound examination.
