- Fig. 1.
The AccuO2 closed-loop oximetry-driven portable O2-conserving device.
- Fig. 2.
Flow chart.
- Fig. 3.
Individual and mean SpO2 values during 48-hour periods at home. P = .006 for AccuO2 versus continuous-flow O2, P = .03 for AccuO2 versus CR-50.
- Fig. 4.
Cumulative percent of time under various SpO2 levels during two 8-hour periods on 2 consecutive days at home. P values compared to continuous-flow O2 for each 1% increment increase in SpO2 are represented by open circles for P values < .05, and by Xs for P values > .05.
- Fig. 5.
Mean conservation ratios during 48-hour periods at home. *P < .001 for AccuO2 versus CR-50 and for AccuO2 versus continuous-flow O2.
