In hospitals, air quality is important. It includes factors like temperature, humidity (how much moisture is in the air), and how well the air circulates. Poor air quality can help germs spread, leading to *hospital-acquired infections* (HAIs), which are infections people get while in the hospital. This study will explore these connections further and is seeking participants.
- The study is for adults over 18 who can stay in the ICU for at least 2 days.
- Pregnant women cannot participate.
