Figure 1.
Effects of intermittent spontaneous breathing during controlled MV on diaphragm force – frequency relationship. This figure demonstrates the effects of allowing spontaneous breathing for five minutes out of every six hours on animals receiving controlled MV for 24 hours. The Control animals received no MV. The intermittent spontaneous breathing (ISB) group maintained more diaphragm force than the animals receiving continuous MV, but generated less force than the Control animals.
