Figure 1: Systemic and cerebral circulatory responses to continuous positive airway pressure (CPAP) at different body positions. Changes in middle cerebral artery mean blood velocity (ΔMCA 𝑉 m e a n ), mean arterial pressure (ΔMAP), cardiac stroke volume (ΔSV), and cardiac output (ΔCO) during CPAP 0 cmH2O (circles), and 10 cmH2O (triangles). A filled circle indicates a statistically significant difference from supine. A filled triangle indicates a statistically significant effect of 10 cmH2O CPAP.
