Comparison of CPAP induced changes in patient and control groups

Patients (n=10) Controls (n=10)
MSNA (%)12 (6)20 (5)
Mean blood pressure (%)7 (1)4 (2)
Oxygen saturation (%)1.1 (0.3)0.3 (0.2)3-150
Pco 2 (%)−12 (3)−13 (5)
  • Values are mean (SEM).

  • 3-150 p < 0.05 (paired t test).

  • (%) = (CPAP 10 cm H2O CPAP 0 cm H2O)/CPAP 0 cm H2O × 100.

  • MSNA, muscle sympathetic nerve activity; Pco 2, partial pressure of carbon dioxide.
