Oxygen Supplies In Disaster Management

The title of this post is the same as this peer-reviewed paper on PubMed.

This is the Abstract.

Mass casualty events and disasters, both natural and human-generated, occur frequently around the world and can generate scores of injured or ill victims in need of resources. Of the available medical supplies, oxygen remains the critical consumable resource in disaster management. Strategic management of oxygen supplies in disaster scenarios remains a priority. Hospitals have large supplies of liquid oxygen and a supply of compressed gas oxygen cylinders that allow several days of reserve, but a large influx of patients from a disaster can strain these resources. Most backup liquid oxygen supplies are attached to the main liquid system and supply line. In the event of damage to the main system, the reserve supply is rendered useless. The Strategic National Stockpile supplies medications, medical supplies, and equipment to disaster areas, but it does not supply oxygen. Contracted vendors can deliver oxygen to alternate care facilities in disaster areas, in the form of concentrators, compressed gas cylinders, and liquid oxygen. Planning for oxygen needs following a disaster still presents a substantial challenge, but alternate care facilities have proven to be valuable in relieving pressure from the mass influx of patients into hospitals, especially for those on home oxygen who require only an electrical source to power their oxygen concentrator.

The Covid-19 situation in India, may be a total different type of disaster, but what is happening in the country is having the same outcome – A serious lack of medical oxygen!

It should not be forgotten, that we nearly had serious oxygen problems last year in the UK.

A Possible Solution

I feel we need to develop a reliable oxygen system that can supply large amounts of medical grade oxygen, which can be delivered quickly and easily to site.

Could The System Be Electrolyser-Based?

I feel that this could be an a possibility.

  • Electrolysers need just a water and electricity supply.
  • They produce both hydrogen and oxygen.
  • If the hydrogen isn’t wanted it can be added to the gas main.

Electrolysers may offer size, safety, weight and other advantages in difficult environments.

The System Must Be Air-Transportable

This would be absolutely essential amd as the equipment might be flying into a serious disaster, surely it would be preferable if it could be fitted into a Hercules.

Conclusion

As I write this post, this article on the BBC has just been published, which is entitled UK Sends Supplies To India Amid Record Virus Surge.

This is an extract.

The assistance package includes 495 oxygen concentrators – which extract oxygen from the air to give to patients – as well as ventilators.

India is seeing thousands of deaths a day amid oxygen shortages.

Will that be enough?

We certainly must be as well-prepared as we can.

The Major Lesson Of The Manchester Atrocity

There is a unbroken thread of the emergency services and ordinary people stepping up to the plate in major disasters in the UK.

It certainly wasn’t broken in the suicide bombing at the Manchester Arena.

I have only been directly affected by one major disaster; The Great Storm. With a little less luck, it would have killed me, as a large chimney was blown through the house  and passed through where I would normally be working.

In the Great Storm, everybody pulled together, just as they did and are continuing to do in Manchester.

One irony, is that the more disasters happen, the better we get at handling them.

As an example on Monday night, Mancunians used similar tactics as had been employed by the people of Dortmund, to look after Monaco supporters trapped in the City because of an attack on the Dortmund team bus.

Perhaps, our inbuilt common sense and survival instinct that has sustained us through the millennia is one of our most powerful weapons against natural disasters, accidents and the evil deeds of losers.

I make no apology for using the word loser.

It will be interesting to see what the reactions of sensible people is in the next few years.

  • Will we see better cooperation between ordinary people of all faiths with the police and security services?
  • Will we see more resilient and safer  architecture? The Japanese and Californians have shown this to be very effective against eathquakes.
  • Will CCTV cameras proliferate and learn how to identify suspicious behaviour?
  • Will it get more difficult to buy dangerous chemicals? Including the acids which are becoming a disgusting weapon of choice of some criminals and wife-abusers.

You’re probably still more likely to die in an accident at home, work or in a road accident, than by the hand of a cowardly terrorist or criminal.
