Figure 8From: Virtual respiratory system in investigation of CPAP influence on optimal breathing frequency in obstructive lungs diseaseBreathing frequency versus an approximation of the respiratory work against lungs compliance. for the minute ventilation equal to 8 l/min and CPAP = 0.0, 0.4, 0.8, 1.2, and 1.6 kPa (the respiratory work is presented as the percentage of the work when CPAP = 0 and the frequency = 6/min). CPAP influences optimal frequency, i.e. the frequency, for which the respiratory work is minimal: the greater the CPAP value, the greater the optimal frequency.Back to article page
