Be older than 18 years old

Timeline

Screening 3 weeks

Treatment Varies

Follow Up continuous collection during both visits (2 hours on back-to-back days). data will be extracted during free breathing (1 minute average before each apnea) and during apneas (10 beats preceding the resumption of breathing to 1 minute after apnea end).

No Placebo-Only Group

Summary

This trial aims to study the effects of breath-holding (apneas) on heart rate and blood pressure responses in human subjects. The researchers are interested in understanding how oxygen concentrations affect these responses and how

Who is the study for?

This trial is for 20 healthy volunteers, including 10 females, interested in participating in research about breath-holds (apneas) and their effects on heart rate and blood pressure. Participants should be able to perform apneas and breathe low oxygen levels without health risks.

What is being tested?

The study tests the consistency of heart rate and blood pressure responses during apneas across different sessions. Volunteers will undergo breath-hold exercises with hypoxia to see if these responses are repeatable within a day (repeatability) and consistent between days (reproducibility).

What are the potential side effects?

Potential side effects may include discomfort from holding one's breath, changes in heart rate or blood pressure due to hypoxia, dizziness, or lightheadedness during or after the apnea exercises.
