How breathing machine settings affect the pupil's light reflex
This trial tests if different breathing machine settings change how the pupil responds to light. It aims to help doctors understand how ventilation mode affects the nervous system.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You are on a breathing machine that pushes air into your lungs (positive pressure)
- You are lightly sedated or awake (RASS score between -2 and 0)
- Your doctor says you are not ready to come off the breathing machine
- Your blood pressure and heart rate are stable during the measurements
- You have a tube in an artery to check your blood gases

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 trial looks at how different breathing support settings (called PEEP) affect how hard your lungs have to work when you are on a breathing machine. The goal is to find the best setting to make breathing easier for you.
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 study looks at how a breathing machine setting (called PEEP) affects blood flow in the brain. If you or your loved one is in the ICU with a serious brain injury and is on a breathing machine, this trial could help doctors understand how to make breathing therapy safer for the brain.
This trial checks whether a tool (called PMIvent) can safely and accurately track how hard you are breathing while you are on a ventilator set to “pressure support.” If it works well, it may help clinicians better understand breathing effort during this common type of ventilator care.
