From: Effects of reduced rebreathing time, in spontaneously breathing patients, on respiratory effort and accuracy in cardiac output measurement when using a partial carbon dioxide rebreathing technique: a prospective observational study

Figure 2

Changes in respiratory values in each patient due to carbon dioxide rebreathing. (a) Increases in minute ventilation (VE) due to carbon dioxide rebreathing. (b) Increases in arterial carbon dioxide tension (PaCO2) due to carbon dioxide rebreathing. Medians (triangles) and interquartile ranges are also shown. *P < 0.05 versus 35 s rebreathing.
