I was recently found to have only 59% blood oxygen level. a nurse hd stopped by my apt. unexpectedky and sart4d chatting with me. she asked me how i was doing and i said just fine. then she asked if she could take a few tests and i said as long as the6 wouldn't take too long because i was about to take a nap. when she putmy finger into that little box she immediatly called an ambulance and rushed me inot the hospital. i didn't know what was going on. But my dr at the hospital explained it to me. he said that my levels weren't just low but "critical".it was so strange to me because i felt as normal as the next person. they kept me in the hospital for nine days. rhey fubally let me go when my levels got up to 89%. because they could notnseem to increase them from there. anyways i just thought i would share.
