A great advancement was at The Pneumatic Institution administered oxygen free of charge to ‘out-patients… in consumption, asthma, palsy, dropsy, obstinate venereal complaints, scrophula or King’s Evil and other diseases, which ordinary means have failed to remove’.
Many of this is still used today such as corrugated non-crushable breathing tubes, mouthpieces and the method for mass production of gases. The Institution then changed to a hospital in later years to help cope with typhis outback in 1800.
‘Most people report that Oxygen Water gives them extra energy and makes them more alert… the effects of inadequate oxygen in the blood are well known. Drinking oxygenated water gives you another path for bringing oxygen into your blood’.4https://www.ncbi.nlm.nih.gov/
Still today oxygen therapy and medical oxygen is still very much used and needed to many patients. This also covers most respiratory diseases plus anaesthesia and treatment of other illnesses. Most forget that it still needs to be prescribed carefully and levels have to be correct and accurate for the patient. We owe many physicians a huge thank you and accolade for their works including what happened in battlefields of first world war where oxygen was used to help soldiers.
