Blood pressure and cardiac output are physiologically linked as both increase during physical exertion [1] and are mathematically related through the formula where blood pressure is a function of cardiac output and vascular resistance [2]. Furthermore, the body actively regulates both parameters through feedback loops to maintain homeostatic blood pressure levels [3].

Sex differences in cardiorespiratory control under hypoxia - Frontiers frontiersin.org 5 facts
claimUnder iso-time hypoxia, physiological responses include increases in heart rate, cardiac output, the low-frequency band of R-R intervals, blood pressure, and vascular conductance, as well as decreases in the high-frequency band of R-R intervals and baroreflex sensitivity.
claimExposure to iso-saturation hypoxia causes increases in heart rate, cardiac output, low-frequency bands of R-R intervals, blood pressure, tidal volume, and ventilation, while causing decreases in baroreflex sensitivity, total power, and the high-frequency band of R-R intervals.
claimUnder iso-time hypoxia, females exhibit higher heart rates, cardiac output, and total vascular conductance, while males exhibit higher tidal volume, ventilation, and low-frequency bands of blood pressure.
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.

formulaBlood pressure is a function of cardiac output and total vascular resistance, analogous to Ohm's law where voltage is the product of current and resistance.
procedureIf sensors in the carotid artery or kidney detect a decrease in blood pressure, the body initiates a cascade of factor actions to alter volume, vascular resistance, and cardiac output to increase blood pressure; if they detect a rise in blood pressure, the body initiates cascades in the opposite direction.

claimPhysiological responses such as blood pressure, cardiac output, and skeletal muscle blood flow increase in anticipation of potential danger or physical exertion, such as an athlete preparing to run a race.
