DEAR DR. ROACH: I’m a 78-year-old man with extreme COPD who’s on oxygen 24/7. I take advantage of a conveyable oxygen generator once I have to go to the shop or for medical appointments. Does the oxygen shield me from getting virus or flu germs, or is it extra seemingly I’ll inhale them with the air and ship it to me in my oxygen? I’m going out seldom and attempt to observe social distancing once I do. I put on latex gloves however can’t put on a masks due to the cannula. – J.T.D.
ANSWER: Oxygen concentrators work by using the distinctive traits of a mineral referred to as zeolite. Underneath stress from a compressor, the nitrogen within the ambiance is adsorbed onto the zeolite pellets within the concentrator.

If there are virus particles within the air, they’re related to liquid, starting from massive droplets to very small ones. Very small droplets can stay within the air for lengthy intervals of time (hours). Some viruses, reminiscent of measles, are capable of stay infectious within the air for a lot of hours, whereas others are extra related to bigger droplets and are infectious for a a lot shorter time within the air. If the infectious particles are within the air, they will theoretically be handed to you thru the concentrator or immediately via the air that can be inhaled via the mouth and nostril.
Thus, with or with out an oxygen concentrator, it’s potential to be contaminated by somebody shut by, particularly one who’s coughing, which expels massive quantities of infectious particles on each massive and small droplets. That’s why the distancing of 6 toes or extra is useful in lowering an infection charges.
Nevertheless, extreme COPD is a significant threat issue for dangerous outcomes in respiratory infections, reminiscent of influenza or coronavirus, which is why staying away from probably infectious folks is so essential.
DEAR DR. ROACH: My husband has an enlarged prostate. Our daughter recommended he eat avocados day-after-day (a minimum of 1/2 of 1 day-after-day).

Avocados are typically wholesome, and a half an avocado a day is unlikely to trigger any total well being issues. Given his success – together with tamsulosin, a typical medicine remedy – I see no cause to cease.
