Daily dietary K+ supplementation improves breathing in CHF rats. A Representative ventilation recordings of ventilatory flow (ml/s), breath-to-breath interval (B-Bi, s) and tidal volume (VT, ml) obtained from one Sham rat, one CHF rat and one CHF+K+ rat. B Representative Poincare plots showing B-Bi variability. C–D Summary data displaying SD1 and SD2 in all groups. Note that irregularity of B-Bi in CHF is markedly improve by dietary K+ supplementation. E Summary data showing changes in breathing irregularity score (%). F Coefficient of variation of VT amplitudes (%). K+ supplemented diet significantly reduces VT oscillations in CHF. *P < 0.05 vs Sham, #P < 0.05 vs CHF+K+.
