measurementIn the study on sex differences in cardiorespiratory control under hypoxia, male participants had a mean weight of 72.95 ± 10.31 kilograms, while female participants had a mean weight of 59.96 ± 12.56 kilograms (p = 0.02).

measurementIn the study on sex differences in cardiorespiratory control under hypoxia, male participants had a mean body surface area of 1.89 ± 0.1 square meters, while female participants had a mean body surface area of 1.64 ± 0.1 square meters (p < 0.001).

procedureIn the study on sex differences in cardiorespiratory control under hypoxia, heart rate, stroke volume, and cardiac output were recorded using a noninvasive trans-thoracic bioimpedance device (PhysioFlow), R-R intervals were recorded via electrocardiogram (ECG Module), and continuous blood pressure was recorded via infrared photoplethysmography (Finometer PRO).

procedureThe experimental protocol for the study on sex differences in cardiorespiratory control under hypoxia involved recording hemodynamic variables (heart rate, stroke volume, cardiac output, blood pressure) and respiratory variables (breathing frequency, tidal volume, minute ventilation, SpO2) after a 20-minute rest period in a sitting position.

claimRubens Fazan Jr served as the editor for the article "Sex differences in cardiorespiratory control under hypoxia: the roles of oxygen desaturation and hypoxic exposure time," while Jui-Lin Fan and Sascha Treskatsch served as reviewers.

claimThe study findings on sex differences in cardiorespiratory control under hypoxia should not be extrapolated to clinical contexts without further investigation into factors such as age, obesity, and comorbidities.

claimThe article "Sex differences in cardiorespiratory control under hypoxia: the roles of oxygen desaturation and hypoxic exposure time" was received by the journal on July 31, 2024, and accepted for publication on January 16, 2025.

procedureThe study on sex differences in cardiorespiratory control under hypoxia excluded individuals with known cardiopulmonary or metabolic diseases and required participants to be healthy, lowlander residents, and non-smokers who had not traveled to high altitudes for at least six months prior to the study.
