Meanings of increase diaphragm in English

On the other hand, bilateral diaphragm EMG recordings revealed that the ability to increase diaphragm activity during respiratory challenge was substantially, and chronically, impaired.

We conclude that CFdi responds specifically to increased diaphragm activation when pressure-time product remains constant.

We evaluated whether increased diaphragm activation would result in a greater decline in the CFdi when pressure-time product (PTPdi) was kept constant.
