Historical information

Inhalation therapy has been used for over 2000 years, but it was from the early 19th centaury that different types of inhalers were developed. In 1865, Dr Nelson invented the improved Nelson inhaler. It is still manufactured today with very few modifications.

Significance

Steam inhalations are used to relieve spasmodic breathing, to disinfect bronchial secretions and to facilitate expectoration of mucus. This type of inhaler may be used at home, without the need fro complicated and expensive equipment.
