Effect of breathing patterns on the perceived magnitude of added loads to breathing

We have studied the perceived magnitude (psi) of a range of externally added resistive (delta R) and elastic (delta E) loads to breathing while varying the flow rate, tidal volume, and inspiratory duration. The sensory magnitude of an added resistive load increased with both the inspiratory flow rate (P less than 0.001) and the magnitude of the added resistance (P less than 0.01). Similarly, the perceived magnitude of an added elastic load …
