Mets could be metastases, a terrible word in cancer. But this is exercise mets. I am half way through my pulmonary rehabilitation for pneumonia and getting stronger. So what is a met? “One MET is approximately 3.5 milliliters of oxygen consumed per kilogram (kg) of body weight per minute.” (from https://www.healthline.com/health/what-are-mets#definition).
Ok, that doesn’t seem very useful. I find this way more useful, a chart of how many mets are used for certain activities:
The treadmill I am using at pulmonary rehab tells me how many mets I am using. However, last time I turned it on and didn’t enter my weight. It uses 155 pounds, which is more than I weigh. I think that then the mets are wrong. It isn’t exact anyhow. The important thing is that I am improving and off oxygen! I am now up to 5.3 mets, going at 3.3 mph, on a 4% grade, for 40 minutes. Pulmonary rehab is twelve weeks, twice a week, with a respiratory therapist and a physical therapist.
My respiratory therapist asks my goals. To bicycle distance, hike across the Olympics, and to ski again, off oxygen. That means altitude. Once we are above 5500 feet, the body really starts noticing the thinner air. I am not there yet but I am so pleased to be improving.
On the chart, I am in the moderate exercise range. To bicycle, I would have to be able to sustain 8 mets. Not yet, not yet.
Being off oxygen (except night, flute, sustained singing and heavy exercise) is GREAT! The intrinsic problem has not been fixed, thought. Fully twenty specialists since 2012 have not figured out why I get pneumonia easily and how to protect me, other than masking and not working in Family Medicine or anything people intensive. It’s annoying, my career has been blown up. I don’t have much hope of an overarching diagnosis at this point, but I’m willing to keep trying. We don’t know everything in medicine and really, I do not think we ever will. It’s endlessly complex and fascinating.
I think the mets chart should be shared with patients. I had one couple who insisted that the woman had PMS even though she was postmenopausal. I scratch my head and continue to watch her. After months something made me suspicious and I order an echocardiogram. She had congestive heart failure, seriously reduced heart output. I promptly called the cardiologist and said, “This is new, she is on NO MEDICINES.” He saw her within a week. Sometimes things do not present in a straight forward manner. She felt much better once we got her heart functioning better. If a person is losing their ability to perform moderate intensity mets, they should see their doctor. It could be spending too many hours in front of a screen (turn it off, get up, go outside, walk daily!) but it could also be something else. Heart is the number one killer still.
Stay healthy and keep those mets up!
Ha. I did use the word certain, didn’t I? And one of my favorite exercises is dancing. Listening to this right now:
