Tracking bicarbonate levels with a breathing test in the ICU
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult admitted to the intensive care unit (ICU) within the last 3 days.
- You are on a breathing machine (ventilator) and expected to stay on it for at least a few hours.
- Your doctor plans to check your blood bicarbonate (a measure of acid balance) at least twice in the next 6 hours.
- You or your family agree to participate.
- You do not have conditions like high oxygen needs, certain lung medications, or kidney/lung support machines that could affect the breathing test.

This study compares two different breathing machine settings to see which one affects how much energy your body uses. It may help doctors better tailor nutrition and care for people on ventilators in the ICU.
This study looks at whether the level of bicarbonate (a substance in your blood) when you arrive at the emergency room can help predict if you might need to be in the intensive care unit or die within the next 48 hours. It's a simple blood test, no extra procedures.
This study watches how exhaled carbon monoxide levels change over time in people in the intensive care unit (ICU). This might help doctors understand recovery and outcomes better.
This study tests a new way to measure breathing difficulty using a small device that checks exhaled carbon dioxide. It may help doctors better evaluate shortness of breath in ICU patients with certain serious illnesses.
This trial tests if a simple, non-invasive measure—carbon dioxide in your breath while your legs are gently raised—can help doctors decide if you need more fluids. It aims to reduce unnecessary fluid use in patients on a breathing machine in the ICU.
This study looks at whether blood bicarbonate levels (a measure of body chemistry) affect how well patients in the intensive care unit tolerate tube feeding. Researchers will track patients who just started tube feeding to see if blood chemistry predicts feeding problems.
