If a person is on oxygen, does that mean that their heart is not pumping correctly?
There can be different reasons for a person to be on home oxygen. Many people on home oxygen have chronic lung problems but people can also be on oxygen if their heart is not pumping strong enough. Yes, the normal oxygen saturation should be over 90%. Heart rate is a little more variable. A "normal" resting heart rate is 60 to 100 beats per minute. With activity the heart rate increases and depending in the condition of the heart, the heart rate may increase quickly with exertion or rise at a steadier, slower pace. The formual for "maximum" heart rate is 220 minus your age. So, for a 50 year old person, the maximum heart rate is 220-50, which is 170 beats per minute. I hope this information is helpful.
