@srasnick98 Hello and welcome to Connect. I have asthma, and I get readings like your husband and I feel fine. It is when it drops below 90 that doctors tend to worry. I know I feel tired if mine drops to around 93 and I just use my inhaler and it comes back up. My elderly mom was just in the hospital with acute respiratory failure and fluid on the lungs with pneumonia. Her oxygen readings were in the 85 range and they put her on oxygen of course. It's probably worth asking your doctor for a recommendation on where numbers should be. Allergies and phlegm accumulation affect these numbers and as long as I address that when it happens, my numbers are usually 96 or 97 %.
