Key result
Inspiratory loaded breathing and voluntary hyperpnea increased blood flow and oxygen consumption in a regular pattern with increases in work of breathing.
Why the study?
How do inspiratory loaded breathing and voluntary hyperpnea affect cardiac output and oxygen consumption in relation to the work of breathing?

May inform estimation of respiratory muscle demand in exercise and disease; leaves open validation in clinical cohorts.
How do inspiratory loaded breathing and voluntary hyperpnea affect cardiac output and oxygen consumption in relation to the work of breathing?
Blood flow and oxygen consumption increase in a regular pattern with increases in work of breathing, which may help estimate respiratory muscle demand in disease and exercise.
COAST et al. (1993) studied this question. Inspiratory loaded breathing and voluntary hyperpnea vs. Resting values was evaluated on Relationship between work of breathing and estimated blood flow to and oxygen consumption by the respiratory muscles. Inspiratory loaded breathing and voluntary hyperpnea increased blood flow and oxygen consumption in a regular pattern with increases in work of breathing.
