Clinical study comparing HomeFill and medical O2 cylinders

SpO2

Borg scale

The small difference in O2 purity did not influence clinical results.

Clinical study comparing XPO2 and Liquid O2

The clinical benefits of a pulse-dose portable concentrator are similar to continous-flow liquid oxygen.

There was no statistically significant difference between exercise capacity of the two groups.

figure 2

The SAO2 during the 6-minutes walking test was very similar in the two groups.

Clinical study comparing SOLO2 and Liquid O2

The clinical benefits of a pulse-dose portable concentrator are similar to continous-flow liquid oxygen.

There was no statistically significant difference in dyspnea change between the SOLO2 pulse-dose and the Liquid O2 continous-flow group.

figure 2

The SaO2 during the 6-minutes walking test was very similar in the SOLO2 pulse-dose and Liquid O2 continous-flow group.
