abstract

  • OBJECTIVE: To evaluate the physiological impact of high CPAP (≥9 cmH2O) vs. NIPPV at equivalent mean airway pressures. STUDY DESIGN: In this cross-over study, preterm neonates on high CPAP or NIPPV were placed on the alternate mode. After 30 min, left and right ventricular cardiac output and work of breathing indices were assessed, following which patients were placed back on the original mode and a similar procedure ensued. RESULTS: Fifteen infants with mean (SD) postmenstrual age 32.7 (3.0) weeks, and weight 1569 (564) grams were included. No differences in LVO [320 (63) vs. 331 (86) mL/kg/min, P = 0.46] or RVO [420 (135) vs. 437 (141) mL/kg/min, P = 0.19] were noted during high CPAP vs. NIPPV, along with no differences in work of breathing indices. CONCLUSION: High CPAP pressures did not adversely impact cardiac output or work of breathing compared to NIPPV at equivalent mean airway pressure.
