Design outcomes

Primary

Measure	Time frame
Quantitative changes of each parameter as a function of time during exposure to the mild hyperbaric oxygen environment / Changes of oxygen saturation rate	—

Secondary

Measure	Time frame
Difference between two groups (healthy adult women and infertility women) in each parameter : skin blood flow, ECG, pulse wave, heart rate, RR interval(Frequency ratio analysis), skin temperature, blood pressure before/after exposure. Reference records : Inside the oxygen room : barometric pressure, oxygen concentration, room temperature, humidity. weather.	—
