I bought a oxygen concentrator and now I feel stupid.
Not one mention of a pulse oximeter, get one, it costs $20. My daughter suffers from pneumonia at the drop of a hat and we told her primary that we are doing so regardless. The script came pretty shortly thereafter. We have two, they produce around 1L/min. There is no good way to measure CO2 outside of blood testing that I am aware of.
As a last resort, I have two tanks of shop(welding) O2 and the necessary valve to run high volume oxygen. I have enough documentation to show there is little difference between shop oxygen and aviator oxygen (mostly due to moisture content) with the understanding that medical grade has more checks and controls for cleanliness and contamination.
Lastly, my wife is an OD and has an insatiable appetite for knowledge, leaving more than a few MD’s backtracking when they are not used to being challenged.
If you get a lung infection, it will reduce your ability to adsorb oxygen. I bought a little SPO2 meter (goes on you finger) to check out some friends. If you are healthy your SPO2 levels should be around 97% or higher. Mine runs 96% (older, diabetic…), so I keep track of it.
The CDC recently had a recommendation that anyone under 94% and a fever should get medical attention soonest. an Oxygen concentrator will get your numbers up for while, but if you have an on-going illness, it will only work for a limited time before additional interventions may be necessary.
Alright, I ordered what I hope are two SPO2 meters, plus two peak flow meters.
The items wordings are a bit different, but I’m 90% sure these are the right items.
I now have two oxygen concentrators due to delivery error.
I simply immediately paid for the second one and send them a mail.
They called me and thanked me.
From what I read a prescription is required to purchase, so I’m curious if you got a prescription to purchase it? If so, how? I would expect someone would need to have low O2 saturation to get a scrip.
Really? I just bought it online.
Where do you live? I live in the Netherlands and ordered one at Oxigo.
In the US the concentrators available for general purchase are not capable of producing much oxygen. They’re not exactly worthless – but the prescription-only devices can produce 5L/min of 90% oxygen which is likely what you would get in hospital. The ones available without a prescription might produce 90% oxygen at 1L/min, but will only produce 30% oxygen at the higher flow rates. They are also not usually designed to work 24 hrs a day.
So if you want the good machine in the US you need to get creative. If you have a foreign passport you can bypass the presciption requirement by claiming to be traveling temporarily in the US. Second hand ones also come up for sale on ebay and craigslist, which is presumably illegal – but it happens. Or maybe you can persuade a doctor to write you a prescription.
Alternatively you could probably buy 4 or 5 of the non-prescription ones, set them to 1L/min each and – with a little bit of improvisation – run them in parallel into the same tube or mask. The price for one of these on Amazon appears to have risen from about $250 to ~$400 in the last few weeks – so you’re looking at $1500 – $2K for this option now :-(.
Tam, I also bought one (2L/min at 90%) and have read some medical journal reviews about how much to use an oxygen concentrator. Generally the advice I read was: a. if encountering a situation such as a heart attack or other episode, just provide high level if not sure, at the beginning. b. the key is to constantly measure blood O2 saturation. If less than 90% then you need supplemental oxygen, to get it up into the 90s. c. Too much oxygen is bad. if you supplement and push the measured blood saturation up to 100% then that is too much (excess O2 might have been added) and back it off to get something like 95-97% measured saturation. d. if you provide 4 liters per minute or higher gas flow rate, then drying is more of an issue and you need to include moisturing bottle source.
Here is a snippet from an article: ” The most recent STEMI guidelines to address oxygen were in 2004.5 At that time, the recommendation was for oxygen to be administered to hypoxic STEMI patients (arterial oxygen saturation <90%, Class I, Level of Evidence B). The guidelines noted that it was reasonable to administer supplemental oxygen to patients during the first 6 hours (Class IIa, Level of Evidence C) but included no guidelines regarding how much oxygen to administer. In contrast, the 2014 AHA/ACC Guideline for the Management of Patients With Non-ST-Elevation Acute Coronary Syndromes recommended to administer supplemental oxygen only with oxygen saturation <90%, respiratory distress, or other high-risk features for hypoxemia.6 The 2015 American Heart Association Guideline Update for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care offered more specific direction on oxygen therapy.7 The systematic review identified observational studies suggesting that excessively high arterial oxygen concentrations (hyperoxia defined at PaO2 > 300 mmHg) may harm various organs or worsen outcomes. Yet it also notes that other studies did not confirm this finding. The guidelines define hypoxia as oxygen saturation <94% and comment that it is more important to prevent hypoxic episodes than avoid any potential risk of hyperoxia. The bottom line recommendation was to use the highest available oxygen concentration until the arterial oxyhemoglobin saturation or the partial pressure of arterial oxygen can be measured (Class IIa, Level of Evidence C-EO). The guidelines also note the “it is reasonable to decrease the FIO2 when the oxyhemoglobin saturation is 100% providing that it can be maintained at >94%.”
Basically this seems to be saying that you must measure blood O2 saturation (with a pulse oximeter) and adjust the oxygen to get the O2 up to about 94-98 %. But dont push it to 100%.
Your thread made me laugh. After listening to the same guy telling us what we needed to survive, I searched Craig’s List and found a used oxygen concentrator for $500. I even bought the tubing and mask and nose tubes on Amazon. The lady wasn’t home the first day I went to get it and when I called her the next day she said it was sold. I was so upset. I thought for sure someone in my family will need oxygen now that I messed this up.
So when you said you feel stupid it made me laugh. I will buy it from you if you wan’t to unload it. But I think your the one who’s better off. We don’t yet know how bad this is going to get.
I also bought one. Thanks for the heads up about the warning on it….I don’t know. I felt stupid buying masks before everyone did and stocking up on werid stuff….I told my wife that I hate doing this too and very much hope that I never have to use any of it and end up donating it all, yet it really is happening and I have no idea how long its going to go on.
No worries OP.
I bought 2 O2 concentrators myself. One of them is brand new from Amazon, which flows 100%@ 1L, 20% @5L max, the second is a used one from med supply house tested, that flows 98% @5L. Both have a place and I hope to not have to use either.
I believe it is better to have and not need , then not to have…especially if you happen to have a CPAP around. There is a great deal of free information out there, as well as access to Telemedicine. I believe the combination of telemedicine and the right medical kit(including pulse-ox) in the home may make the difference, YMMV.
I purchased an inogen one oxygen concentrator (portable) and it can do 5l/m at 90% from what I understand. Hopefully I will not need to use it and will sell it after this is all over.
