Understanding Oxygen Concentrators

Everyone is talking about oxygen concentrators now. Most of us had not heard of them before. Many know about distillers which extract water from air, yet very few realised that even oxygen can be extracted from air. So what is an Oxygen Concentrator and how do you choose the right one?

The most important is to understand that Covid patients require 90% Oxygen concentration at 1to 5Litre flow and above to 10L

Tips on Selecting the right oxygen concentrator.

The most important is to understand Covid patients require 90% Oxygen concentration at 1to 5Litre flow and above to 10L when they are suffering with acute respiratory discomfort.

90% oxygen concentration is the most important point here.

  1. We can break down oxygen concentrator into small (5 to 10 kg) oxygen concentrator suitable for COPD patients, medium (15 to 19kg) and large (20kg and above) oxygen concentrators are suitable for critical care and for COVID patients.
  2. Small oxygen concentrators can have options from 1 Litre to 9 Litre Flow but this does not mean you get 90% oxygen at higher flow like at 5 litre. On small oxygen concentrators 90% oxygen contration is achieved only at lower flows of 1litre to 2 litre. on higher flows the oxygen concentration drops to 30% as you increase the flow. Suitable for COPD patients but not for COVID patients.
  3. Check the specs of the oxygen concentrator and if you see 90% – 30% or ( 1L/min , 2L/min) means 90% oxygen is available only at 1Litre flow or 2Litre flow respectively and on higher flows oxygen drops to 30%. The air we breathing is with 29% oxygen. So small (5kg to 10kg ) oxygen concentrator at higher flows gives output of 30% oxygen means its just blowing air.
  4. weight is the best indicator to understand the oxygen production capacity.

A 5kg to 10kg oxygen concentrator means a small compressor which will only mange to give an output of 90% oxygen at 1 litre to max 2 Litre

A 15kg to 19kg Oxygen Concentrator will have a compressor that can easily give an output of 90% oxygen at flows from 1 Litre to 5 Litre Oxygen (Ideal for COVID patients and critical care patients)

A 20 kg and above oxygen concentrator will have a large compressor which can give an output of 90% oxygen from 1Litre to 10Litre flow. (Ideal for COVID patients and critical care patients and for dual patients to use same machine with accessories)

Please do not only see the output flow of an oxygen concentrator like 5litre, 10litre or so. the most important is to make sure you get 90% Oxygen at highest flow level.

For a small family with no senior citizens a 5 litre at 90% oxygen concentration should be good enough.

For 2 senior citizens or for a big family 10 litre at 90% oxygen concentration should be good enough as it can support 2 patients at once if the need arises. And can assist senior citizens during home critical care if the need arises.

Please do not get fooled and pay big money for small oxygen concentrator sold by highlighting 5 Litre and 8 Litre and do not give an output of 90% concentration of oxygen at higher flows which is the need of the hour.

Please read the specs well and if required please ask your supplier to show you the oxygen output on an oxygen analyzer at higher flow of 5 Litre or 10 Litre.

Also most importantly consult a doctor before you invest your hard earned money in the device. Right now, because of a shortage of oxygen supplies, the concentrators are overpriced. As soon as supply meets demand, the price of concentrators will come down.

Every possible doubt about Covid vaccine cleared by Dr. Reshma Hingorani

Dr. Reshma Hingorani wholisticwellnessspace.wordpress.com

What is the recommended dose and schedule?
Do you need to take it even if you had Corona?
How many days after getting vaccine, would I develop protection?
How long will the vaccine provide immunity?
When is the Corona vaccine likely to be available in India?

These and many more questions answered.

  1. What is the recommended dose and schedule?
    Two doses given 21 days or 28 days apart depending on vaccine used.
  2. What if I take only one dose?
    One dose will give you only partial protection of maybe 60-80% and will not last long enough. For complete protection you must take two doses at recommended intervals.
  3. What if I forget to take the second dose? Should I take the first again?
    Just take the second dose at the earliest. No need to repeat the first dose.
  4. Are both doses same?
    In most of the vaccines it will be the same dose given twice. However, Sputnik- V vaccine has both doses as different vector viruses, so will be marked as dose 1 and 2. Oxford-AZ vaccine may also come out with first dose as half dose.
  5. Do you need to take it even if you had Corona? After how many days of getting cured?
    Yes. But that will be last in the priority list. You can let others take who probably need more than you. You might need it earlier if you did not develop an antibody response.
  6. Can it be administered to an individual who has received plasma as treatment for Covid?
    The donor plasma contains anti Covid-19 antibodies and may suppress the immune response to the vaccine. As it is, those who have recovered from Covid-19 may not need the vaccine in the early phases.
  7. Can a pregnant lady or a lactating mother take the vaccine?
    No company has yet tested the vaccine in pregnancy. CDC has advised against giving the vaccine to pregnant and lactating mothers. UK authorities have advised women not to get pregnant for two months after the shot. Since the vaccines available till now are not live vaccines, it should not cause any problem if given inadvertently.
  8. Can a diabetic patient take the vaccine?
    Yes, in fact diabetes has been established as a risk factor for severe disease and all diabetic patients must get vaccinated on priority.
  9. If offered a choice of vaccines, which one should I take?
    All vaccines are offering equal efficacy although local reactions may be different. Take whatever available. Think positive that at least you are being offered a vaccine ahead of others. Indian manufactured vaccines will be more suitable for our population as they are cheaper and can be kept at 2-8 degree Celsius. The mRNA vaccines require a storing temp of -70 (Pfizer) and -20 (Moderna) which may be difficult to maintain in summer months.
  10. How many days after getting vaccine, would I develop protection?
    It takes time for your body to build protection after any vaccination. COVID-19 vaccines that require 2 shots may not protect you until a week or two after your second shot.
  11. How long will the vaccine provide immunity?
    It is a new virus, new technology vaccine, so we don’t know. After follow-ups of these vaccinated population and their antibodies for a couple of years, we would be wiser. The need for boosters and when will they be required, will be decided after these follow ups and mathematical modelling.
  12. Children of what age can be vaccinated? Is the dose same as adults or lesser dose to be given?
    Trials done till now have been for adults above 18 only. Now trials for children above 12 have started. Doses will be decided only after trials are done on younger children and infants.
  13. Can it be given to immunocompromised individuals?
    The mRNA vaccine and inactivated vaccines are safe. AZ and Sputnik-V adenovirus vector vaccines are also safe as they are nonreplicating viral vector vaccines. Live vaccines and replicating viral vector vaccines will have to be avoided.
  14. What are the side effects expected?
    The side effects reported by the trial population are mostly mild Covid like symptoms like some fever and fatigue. Local injection site pain and induration is also reported. Reports of transverse myelitis and facial palsy have not been found to be related to the vaccine. Generally, all vaccines are safe. Although these vaccines have been made in record time, the testing methodology and procedures have not been compromised.
  15. I am allergic to egg. Can I take the vaccine?
    Egg cell lines are not used for production of these vaccines. They can be taken safely even if you are allergic to egg.
  16. I heard that it has pig or monkey products? I am a pure Vegetarian.
    The new vaccines manufactured these days are devoid of any such products.
  17. In the past vaccines have been linked to Autism. What about these?
    In 1985 there was a paper linking MMR with autism. Millions of children followed up after that have conclusively proven that there is no relationship between vaccines and autism. All vaccines are extremely safe with minimal temporary side effects.
  18. There are messages going around that mRNA from vaccine gets incorporated into the human genome and alter our genetic structure. Is that true?
    mRNA vaccine carries a message to the cell to produce spike protein which induces antibody production. It does what it is directed to do. Till date there have been no adverse events reported.
  19. What is the interaction of alcohol and Covid vaccine?
    Excessive alcohol can reduce the immune responses to vaccines. Since Russians are known for heavy drinking, their government has advised to avoid drinking two weeks prior to first dose and 6 weeks after the second dose. The Sputnik vaccine is given as two doses 21 days apart. Occasional glass of wine or beer will not interfere with the immune response.
  20. Soon the virus will mutate and we will need another vaccine. Should we not wait?
    Till now the virus has not shown tendency to mutate like the Flu virus. Moreover, the vaccines being developed have taken this into consideration and should still work.
  21. What if I do not want to take the vaccine? Will it be made mandatory?
    In majority of countries, it will not be mandatory. You have to choose between the new viral disease with no specific treatment and a new vaccine. Choice is yours. As initially there will be a huge demand supply gap, by not taking a vaccine you can help others.
  22. Can I roam around without a mask once I am vaccinated?
    No, not as of now. One may do so only when the majority of the population has either got the disease or received the vaccine. This means the population has developed herd immunity.
  23. Are newer and better Covid vaccines expected in near future?
    As of December 2020, more than 250 vaccines are under trial in different phases. A lot of research is underway to develop newer delivery methods also. Nasal spray vaccine is probably the most promising. A multi dose nasal spray delivery device can be very convenient and economical. It will produce local IgA antibodies and block the virus at entry itself. It will reduce nasal colonisation and thus prevent transmission of disease also. Unfortunately, since it will be a live vaccine, it will need maximum and most stringent trials and thus will take longest time to hit the market. Covid-19 is still a new disease and we are still learning. The facts mentioned above are as of 14 December 2020. Please re-check the facts before taking a Covid vaccine shot.

Covid19 – Lessons Learnt From a Life Forgotten/ Neelam Jain

Life “is a tale told by an idiot, full of sound and fury, signifying nothing.” So said Shakespeare in Macbeth, a tragedy of epic proportion where the eponymous hero fell because of only one tragic flaw: “Vaulting ambition, which overleaps itself.”  Covid19 brought the “sound and fury, signifying nothing” part of Macbeth like a thunderbolt rolled onto an unsuspecting mankind. And Hamartia, or the tragic flaw, that Shakespeare’s tragic heroes had, has its echo in present times too. Covid19 lays bare our fault lines and exposes our flaws like never before. It has, in fact, come as a great teacher to mankind – perhaps because the ‘kind’ in “man” had shrunk to a miniscule level. It has given us a huge nudge to readjust our priorities that were slinking to abominable levels of putrid materialism.  Hmm…..looked closely, it also has been a period of wish-fulfillment, the collective wishes of entire mankind, or rather man-unkind, witnessing fruition of shared desires in a way unparalleled.

To further explain my points, let me take the first premise of collective wish fulfillment. Was the entire human race not clamoring for clearer skies, cleaner air and sparkling water? Millions of dollars were being spent on hosting international meets that often ended up revealing more dissensions than agreements. Each country blamed the other for being a greater polluter, never wanting to clean its own Augean stables. Year after year, there were foreboding studies that announced imminent doom of the planet if countries did not clean up the environmental mess. Countries met, they bickered and blamed each other, and dispersed.

Then, in one fell swoop all pollution abated….. people could not believe the blue of sky could actually be so inky blue and clear, and the air going into human lungs could be wholesome without causing the rasping cough and blocked sinuses. My family ate green leafy vegetables without fear of them being laced with industrial waste – the water hitherto being let out in the fields outside Delhi from where our produce comes.  How often have we wished for lesser congestion on roads. Traffic, everywhere had become a nightmare. Each time we were caught in serpentine traffic snarls, it was nostalgia time. “Oh, when I first came to Delhi more than 30 years ago this road was deserted, and it almost felt unsafe driving here late in the evening!” One lockdown, the beginning of a series of them, and you were transported back to the “good old days!” Maybe, the definition of “good” was no longer the same because now it was tinged with fear of the unknown, unseen, tiny virus that was keeping everyone indoors.

“Monday morning blues” was the litany of all working people. I remember beginning to feel the blues just when Sunday dawned. Why can’t weekends be longer, was the refrain echoed in all corners of the world – languages varied, refrain the same.  “Let all days be Sunday,” said the mighty voice. And we all huddled home every day, day after day. Beautiful day-planners lying on the desk were an investment most futile!!

Don’t blame any virus or any government for the pandemic…..all wishes are coming true. Is it self-fulfilling prophesy, or mere Ignis Fatuus!  Is it a passing phase, or the new world order is here to stay. Only time will tell.

One thing is for sure. The virus is not atemporal. It may either gradually die a natural death after peaking, or human intervention will see it rendered less menacing. Whatever it may be, but it surely will have taught us the much-needed and long-forgotten basic lessons before it exits.

First and foremost, Covid19 has added the fundamental Pause button to human race – race, both as noun and verb – the former defining the species, and the latter their feverish scurrying forth. I feel it has made us stop as the traffic light gradually turns red, so that we have time to reflect until it turns green and hence signal us to recalibrate our speed and direction.  We were all racing from morning until night, 24X7, in pursuit of something that was always outside our grasp.  Were we not all running away from life, looking for a meaning in a place it did not exist.  And now, staying within the confines of our homes we are learning to live with ourselves. Most friends and family I have spoken to have expressed how little we actually need in life and yet we carry the heaviest baggage. Our priorities had gone misplaced and it is time to set them right.  

What is of utmost importance is human life. This lesson, unfortunately, a deadly virus had to come and teach us. It has showed us that we need to value people and use things when we had been doing the reverse – Valuing things and using people. Time for some reverse-engineering. Time to smell the coffee!

People in lock-downs, living away from families learnt the value of a family, and those locked with their families are learning to share, care, and the biggest of all, to let-go. Sharing limited home space has strained many a family, for the virus leaves no option of quietly slipping away from home in case of any friction.  And therein lies the lesson of developing tolerance. “Love me when I deserve the least because that is when I need the most,” my friend’s recalcitrant teenager told his mother. Mighty lesson that is! Equally relevant for the youngster and his mother.

Role Reversal

A huge take-away of Covid19, and, undeniably the most important to my mind, is that of empathy towards all living beings. We feel caged and suffocated inside homes. Our freedom is gone. But we are safe. Juxtapose that with slaughter houses and abattoirs where animals and birds are crammed and squished together. They are caged, and they know they will soon be slaughtered. They live with the constant ordeal of impending death. Try to feel what trauma we are subjecting them to. If we want to break free and breathe freely, do we have any right to encage other living beings and then butcher them. All this merely to satisfy our taste buds. Yes, time to rethink our values.

“It would seem resourceful, perhaps wise, to use suffering as a vehicle of transformation that allows us to open ourselves with compassion to those who suffer as we do, or even more than we do”, said Matthieu Ricard in his book Happiness. Roman philosopher Seneca once said that “Suffering may hurt, but it is not an evil.” Schopenhauer, the German philosopher may have had similar belief when he said that suffering is the purifying process through which alone, in most cases, a person is consecrated.  Sure enough, no one wants suffering and all human endeavor is towards forswearing it. However, it can be argued that while suffering by its very nature is abhorrent but when unable to avoid, we can use it to learn and to change.

While we wait with bated breath for this Covid19 to pass, we can only forget the lessons it continues to teach us – both, at the physical level and at a deeper existential, philosophical level, at our own peril.  In the latter half of this century when it is well behind us, and human race has the wisdom of hindsight, Covid19 may seem to be the one game-changer humankind desperately needed for course correction.

I started writing this piece when we were, what is now known as the middle of Covid, or the first phas (It may be known differently sometime down the line) . As we are a cat’s whisker away from getting the vaccine, these disembodied times however seem  here to stay for a while. I’m quite inclined to close with Hafiz : “I wish I could show you, when you are lonely or in darkness, the astonishing light of your own being!” So instead of taking a world trip, go inside yourself and find the true essence. Nice things, beautiful scenic places, gourmet food and all the pompous pursuits of men are a happy place to be in, but the joy they provide is never ever-lasting. It is transitory. The value of things is only the value we ascribe to them. As Vivekananda said: “Things are dead in themselves. We breathe life into them, and then we either run after them or run away from them.”

Covid-19 has provided a big insight into what really matters in the race we call Life. The Pause-button ought to make us reflect on where we were headed, and which direction we need to take. Almost a year into the pandemic, the self-importance of man dissolves in laughter. Life will never be easy. It will always be hard, but we can choose our hard wisely. Look to the light within, for the more light you allow within you, the brighter the world you live in will be.
