COVID-19 Oxygen Supplementation 

The entire world is going through some uncertain times as COVD-19 continues to rise in it’s confirmed cases across the planet. While the virus is not as deadly as some of the viruses the world has seen before, it’s voracity to spread is quite disturbing. One of the devices that Harmony Home Medical has stocked up on to ensure we can help our clients are oxygen concentrators, both stationary and portable. Corona Virus can cause a lot of respiratory distress and most patients who do die are as a result of extreme respiratory failure. With these sorts of symptoms, oxygen concentrators can prove to be very helpful in providing supplemental oxygen to relieve pain or difficulty breathing, and shortness of breath. Extra oxygen can also help to expedite the body’s healing process.

Notice: May 2021

We do have  5 Liter and 10 Liter Oxygen Concentrators available.
Please Call our office at (858) 560-8177 

Please note you need an prescription to purchase a oxygen concentrator, or if this is a donation we will need a letter stating who the oxygen concentrator is for please call our office for further assistance.

Do you need an Oxygen Concentrator for Covid-19?

While it’s good to be precautious, it can cause problems if everyone goes rushing for an oxygen concentrator as a preventative measure (much like our unnecessary lack of toilet paper in the stores right now?). Discuss the option with your physician should you not be feeling well and remember that oxygen REQUIRES A PRESCRIPTION. A physician must “ok” you taking supplemental oxygen. There are no real dangers or negative consequences of using supplemental oxygen responsibly, meaning at a low healthy dose (1-3LPMS), but nonetheless it is a controlled substance. If you are elderly or have existing respiratory conditions (asthma, COPD, etc) then it may be a good idea to meet with your physician in the near future to discuss him or her being able to expediently write you a prescription should you get COVD-19. If you don’t have a plan in place with your physician, and then you get COVD-19, they may delay seeing you in order to not spread the virus. In that case, you may have longer-than-healthy delays in getting your RX.

Types of Oxygen Concentrators 

Portable Oxygen Concentrator or tank?

Oxygen Concentrators 

Companion 5 Stationary Oxygen Concentrator is compact and lightweight Home Oxygen Concentrator. Weighing only 36 pounds, this oxygen concentrator is easy to lift and transport. Four caster-wheels enable the unit to effortlessly glide across carpeting or other common floor surfaces. This Home Concentrator is 12.5 inches wide, 21.5 inches high and 13.5 inches deep. Its small profile is easy to a position near a bed or furniture without taking up too much room.

Companion 5 Oxygen Concentrator employs both autoFLOW and ultraSILENT technologies to provide highly efficient, and less obtrusive, Oxygen Therapy. This technology enables the machine to have lower power requirements and emits less noise — Companion 5’s maximum power draw is only 350 watts and it emits a hushed 40 dBA when operating at 2 LPM. This noise level is similar to a quiet conversation or the hum of a home refrigerator, meaning this Oxygen Concentrator won’t keep you up at night. Making ownership even easier, the Companion 5 Concentrator only requires maintenance every two years! The intake filter is easily accessible through a handy filter door, allowing for quick inspections and replacements.
