VH-2 home oxygen concentrator has a nebulizer function. A nebulizer is a medical device used in respiratory therapy to deliver medication directly into the lungs in the form of a mist. It converts liquid medication into fine particles that can be easily inhaled by the patient. Nebulizer therapy involves using a nebulizer to administer medication for the treatment of respiratory conditions such as asthma, COPD, cystic fibrosis, and more. It is suitable for patients of all ages, and is highly effective in delivering medication directly to the lungs, providing quick relief and targeted treatment.
What is the difference between continuous flow and pulsed flow?
Pulse flow concentrators deliver the required oxygen only when you breathe in. While continuous-flow oxygen concentrators provide a constant flow of oxygen, regardless of whether you are inhaling. Continuous flow is suitable for those who need a non-stop oxygen supply, while pulse flow is mainly used on portable oxygen machines for lower power consumption and longer battery life.
Is VH-2 heavy?
NO, VH-2 is not heavy at all. Although it is a home oxygen concentrator, it is rather light and compact. Weighing only 12.13lb, it allows you to move it around your home or take it to your car with no trouble.
Can I use VH-2 overnight?
Yes. The high-quality compressor in Vh-2 allows for continuous use up to 48 hours. It operates quietly with a noise level as low as 48 dB, so you can sleep soundly while using it over the night.
I run this concentrator for several hours a day, and it performs consistently. Noise level is low, and maintenance is simple. Highly recommend for home care.
The VH?2 runs at just 48?dB, so I can use it overnight without disturbing anyone. The flow settings (1 to 7?L) give me a lot of flexibility, and the oxygen purity feels very stable.
I got this for my 72-year-old mom. She loves how quiet it runs and how simple the controls are. The steady oxygen flow helps her sleep better every night. Definitely worth it!
I’ve been using this oxygenator myself, and later I found out that when my two daughters, who are dog breeders, have newborn puppies, some of them are weak and struggle to breathe. I felt really worried, so I decided to buy one for each of them. We tried other small devices before, but either the oxygen output was unstable or the operation was too complicated—they always let us down when we needed them most. It wasn’t until we started using this one that we felt at ease.
Now, whenever my daughters have newborn puppies that are low on energy and need oxygen supplementation, they use this machine right away. The oxygen output is steady, and it’s easy to adjust the levels, allowing us to control the oxygen supply precisely without harming the fragile little ones. Since we’ve had it, those puppies that were originally listless quickly regain their energy—they start looking for milk on their own, and their fur gradually becomes shiny. Watching litters of healthy, lively puppies grow up, without having to worry about them having problems due to oxygen deficiency, we all feel really relieved. This oxygenator truly helps us give the puppies the care they need right when they need it; it’s so practical!
This Varon oxygen concentrator looked compact, so I decided to switch to it for a try—and now that I’ve been using it, I’m really glad I made that choice back then!
It’s perfectly sized; I can just place it directly on my home office desk without taking up much space. Using it daily is simple too: press the power button, put on the nasal cannula, and it’s ready to go. No need to adjust settings repeatedly—totally hassle-free. It makes a slight noise when running, but it’s not loud. You might notice it at first, but after 10-15 minutes, you’ll get used to it. Whether I’m using it while working or sitting nearby reading, it never gets in the way.
What satisfies me most is its performance—it supports a maximum flow rate of 7 liters per minute, which is more than enough when I occasionally need higher oxygen flow. It also has a timer function: set the time before bed, and I don’t have to get up in the middle of the night to turn it off—super convenient. Additionally, its humidification chamber is really useful; adding water keeps the oxygen from feeling dry, making my throat much more comfortable when inhaling. That said, I do wish the humidification chamber was a bit larger, so I wouldn’t have to refill it so often. I even figured out a little trick for it: I fill a spare bottle with water and add a few drops of peppermint essential oil, then pour some into the humidification chamber whenever I need to refill it. Inhaling the faint peppermint scent while using the machine feels so refreshing—I truly can’t live without it now!
I appreciate the quiet operation and stable oxygen concentration. Setup was straightforward and the unit feels solid. Would recommend for anyone needing dependable home oxygen support.
Napakahusay ang kasiyahan ko sa unit na ito! Mas mahimbing na ngayon matulog ang asawa ko at hindi na siya nagigising na hirap huminga. Tahimik at madaling i-set up.
