Clinical Trial Summary

The aim of the project is to evaluate the effect of hypercapnia on physiological parameters in a healthy person during short-term hypoxia and hypercapnia.


Description:

Hypercapnia causes changes in physiological parameters at various levels throughout the body. The study aims to evaluate the effect of hypercapnia on physiological parameters in a healthy person during short-term hypoxia and hypercapnia. It is an intervention prospective study that will be conducted at the Faculty of Biomedical Engineering on healthy volunteers. All the volunteers undergo three different phases in random order. The individual phases differ in the breathed mixture of oxygen, nitrogen and carbon dioxide gases. Non-invasive measurements of physiological parameters, especially blood oxygen saturation, perfusion index and cardiac output, will be performed continuously during the experiment.
