I've been looking for a fitbit type of monitor that also tells me my O2 saturation levels for years. I was just at COPD10 and there's one that will be available in the US sometime relatively soon. I'm not trying to sell or promote this thing, but I think I will find it extremely useful for exercise and monitoring my O2 levels and others may as well. It means I won't have to have a fitbit and my oximeter when I go to the gym. Want more information? Email me.
To the moderators: if this doesn't pass muster, is there a way that someone can word it so it does? I'm really just trying to give information I think would be useful to some people.
