Dataset of respiratory and cardiorespiratory responses to low-concentration CO₂ supplementation during resting and cycling at high altitude

This dataset is a physiological dataset collected in real high-altitude environment, covering resting and cycling states and respiratory interventions. The dataset comprises respiratory parameters, peripheral oxygen saturation, and heart rate. We envision that this dataset will advance understanding of human acclimatization and support the development of strategies to mitigate acute mountain sickness.
