The arterial carbon dioxide tension (Pa,CO2) during NIPPV with either the F-mask (5.56+/-1.35 kPa) (mean+/-SD) or the C-mask (6.87+/-0.96 kPa) was significantly lower than during spontaneous breathing (7.75+/-0.81 kPa; p<0.003), but the Pa,CO2 decreased more during NIPPV with the F-mask than with the C-mask (p<0.003). The VD was significantly smaller (p<0.03), the air leak was significantly less (p<0.03), and the VA per breath was significantly larger (p<0.03) during NIPPV with the F-mask than with the C-mask. In conclusion, nasal intermittent positive pressure ventilation with the F-mask was more effective than nasal intermittent positive pressure ventilation with the commercially available mask due to its smaller dead space and less air leak. Further studies are needed to extend these results to all the commercially available-masks. ER -
