Could a simple cuff pressure replace invasive breathing monitors?

This study looked at whether measuring the pressure in the cuff of a breathing tube can accurately assess how hard a patient is working to breathe while on a ventilator. Researchers compared this new method to the standard, more invasive technique that uses a sensor in the esophagus. Thirty stable patients on ventilators were tested at different breathing support levels. The goal is to find a simpler way to monitor breathing effort and improve ventilator care.
