This study is for patients in the ICU (Intensive Care Unit) who need a machine to help them breathe, called mechanical ventilation. The goal is to see if using a special sedation method can help these patients do better. Sedation is medicine that makes patients sleepy or calm. In this study, two groups will be compared: one uses a new sedation method checking respiratory drive (how well patients breathe) using a measure called P0.1 (pressure at the start of a breath) and RASS (Richmond Agitation-Sedation Scale) which checks how awake they are. The other group uses the regular method focusing only on RASS.

• The study lasts for 48 hours, with patients randomly placed in either the new or regular sedation group.
• Patients will be checked regularly, and medicines adjusted to keep them lightly sedated.
• Researchers will look at how long patients stay in the ICU and hospital, and the success of taking them off the breathing machine.

Participants must be 18 or older, in the ICU due to a breathing problem, and have been on a ventilator for less than 72 hours. Some conditions like pregnancy or certain medical issues may exclude participation.
