Respiratory Therapist/oxygen readings good but still winded

Question
I am curious as to why my husband who is in heart failure can have good oxygen reading of 97 or better and yet be so winded when he does anything such as walking to the mail box. Thanks for your response.

Answer
Good morning,

Thank you for entrusting me with your medical question today, I hope I am able to help make sense of some things for you. Our body's oxygen level (Normal SpO2 is 92-100%# and our lung function, while often connected items, are also often mutually exclusive of each other. What this means is it is possible to have a normal oxygen saturation (97%), yet have less than optimal lung function.  This scenario is fairly common in CHF patients who are moving oxygen through their body fairly well, yet they get short-of-breath because the excess fluid in and around their lungs is pressing on the lungs and causing restricted expansion... which leads to labored breathing. Same concept applies for a lung disordered-patient who has a poor SpO2 #say, 80-85%) due to the body's inability to transfer oxygen through the blood stream like it once did, yet their lungs are moving air well and they are not very winded. I hope this helps.

Best of health,

Larry, RRT
