Hello. Thank you for coming to JustAnswer with your question, and welcome.
The gadget you are referring to is a pulse oximeter. If you put that into your search engine, you will see that you can buy these online. You can also buy them at a local medical supply store, or even your local pharmacy, Walmart or CVS.
Ask to speak with someone before deciding what type to purchase. They are basically all the same as far as the results you get (showing percentage of oxygen in the blood and a pulse rate), and how the device is used (some are placed on your finger, others on your wrist). However, I am sure as with anything else that some are better made than others.
That would really depend on your mother's condition (she may have other cardiovascular conditions in addition to the emphysema); and on her doctor. You might want to contact her doctor and ask if this would be sufficient for him to prescribe oxygen.
The pulse oximeter is frequently used in clinical and hospital settings to monitor patients, however in these settings there is other monitoring being done, as well as professionals that can judge the accuracy or relevancy of the pulse oximetry itself.
A pulse oximetry reading alone may not be enough for her doctor to make a judgment about use of oxygen. In some people with emphysema, the use of oxygen can be dangerous.
In the U.S., it would usually be possible to send a professional medical person to the home environment to do an assessment. Even a professional nurse trained in home care could help. You might ask the doctor in Poland if this is possible in this situation. If not, it really would be best for her to get to a hospital so that she can be fully assessed.
Hi, sorry for the delay.....I had to be away from the computer for a time.
The pulse oximeter will only give you readings for oxygen saturation and pulse rate.
It does not replace the "gazometry test", or as it is called here....arterial blood gases, which include levels for oxygen content (as well as saturation), carbon dioxide, bicarbonate, the blood pH level. Here is a link that explains from WebMd: Arterial Blood Gases.
So, again, it would be necessary to contact your mother's doctor to find out whether the pulse oximetry alone would be helpful in enabling him to order oxygen for her.
