简要总结
The aim of the project is to experimentally determine the effect of the choice of finger for the placement of a pulse oximeter sensor on the results of measuring peripheral blood oxygen saturation (SpO2) in a healthy person with short-term hypoxia and hypercapnia.
详细描述
The aim of the project is to experimentally determine the effect of the choice of finger for the placement of a pulse oximeter sensor on the results of measuring peripheral blood oxygen saturation (SpO2) in a healthy person with short-term hypoxia and hypercapnia. This is an intervention prospective study that will take place at the Faculty of Biomedical Engineering, especially on FBMI students. The experiment consists of two phases, in which in the first phase, the volunteers will inhale the hypoxic mixture for five minutes after the stabilization phase. In the second phase, volunteers inhale a hypoxic and hypercapnic mixture. During the experiment, non-invasive SpO2 measurements will be performed continuously on individual fingers of both volunteer hands.

研究组 & 干预措施
Hypoxic
In this phase, participants inhale the hypoxic mixture for five minutes.
干预措施: Breathing a mixture of O2, N2 and CO2 and monitoring SpO2 on each finger (Other)
Hypoxic and Hypercapnic
In this phase, participants inhale the hypoxic and hypercapnic mixture for five minutes.
干预措施: Breathing a mixture of O2, N2 and CO2 and monitoring SpO2 on each finger (Other)
结局指标
主要结局
Does it depend on which finger is the sensor placed for SpO2 values?
时间窗: Up to 12 weeks
The experiment can help determine if it depends on which finger the finger sensor will be placed to measure SpO2. Appropriate finger selection for SpO2 measurements could help to better interpret the measured values and possibly increase the success in diagnosing health events.
