Since I and some others do not do facebook ...
I am going to re-post this, in a form everybody can read...
It is good sound advise.
This is very similar to what my neighbor wrote down, before she left to help others. A retired Nurse.
The only addition I would add to this. Is to get and use an pulse ox meter.
These ox meters are not medically accurate, often vary + - 2%.
A pulse ox below 95 percent is considered low. It’s important to know what’s normal for you. It isn’t uncommon for people with COPD to maintain their pulse ox levels between 88 - 92%
So here is what you do. Measure your ox level when you know you are at your normal health, then if other symptoms appear, measure often, and watch out for a downward trend.
@corlin Also using a pulse oximeter like most machines has a learning curve. Please keep in mind that you should take the reading multiple times to confirm consistency especially if you are unused to the equipment.
