ClinConnect Summary

This clinical trial is studying how the position of a special temperature probe placed in the esophagus affects the accuracy of measuring core body temperature, especially in emergency situations like severe hypothermia. Accurate temperature readings are crucial for making important decisions about treating patients, particularly those who are in cardiac arrest. The researchers want to find out if placing the probe too high in the esophagus, close to the trachea (the windpipe), could give incorrect, lower temperature readings, especially when patients are breathing in cold air.

The study is looking for healthy volunteers aged between 18 and 75 who are generally healthy (with an ASA score of 2 or less, which means they have no significant health issues). Participants will take part in tests where they will breathe in both room temperature and very cold air while the temperature probe is placed in different positions. This will help researchers see how the probe's location affects temperature measurements. It's important to note that individuals with certain health conditions, pregnant women, or those who have had recent illnesses are not eligible to participate.
