Comparing breathing machine settings and body energy use

This study tests a non-invasive breathing test to estimate bicarbonate levels in critically ill patients on a ventilator, potentially reducing the need for frequent blood draws. It may help doctors monitor your acid-base balance more comfortably.

This trial compares two different ways a breathing machine can help you breathe. It uses a special imaging technique to see which method works better for patients in the intensive care unit.

This study looks at how different settings on the breathing machine (ventilator) are used for critically ill adults in the ICU. It may help doctors improve care for people who need a breathing tube.

This trial studies how small changes to a breathing machine can affect how short of breath you feel. If you are in the ICU and awake, you may be able to help doctors learn how to make ventilator settings more comfortable.

This study is testing how different settings on a breathing machine affect your breathing effort and drive. It may help doctors find the best ventilator settings for patients with severe low oxygen levels.

This study compares two types of breathing support for people on ventilators in the ICU. It looks at how each method affects the body's natural control systems (like heart rate) and may help find a better way to support breathing.
