Long ago, Ancient Egyptians
inhaled fumes of herbs heated on bricks. In the 19th century
cigarettes were used. And finally after about a hundred years of experimenting,
the first mass produced nebulizer was invented in 1969. Since then, the nebulizer
has really been a lifesaver for many asthmatics.
The concept of the
nebulizer is quite simple – inhaled asthma medicines go directly to the lungs
and may instantly relieve asthma symptoms.
Ancient techniques did
this, but they were slow and inefficient. The modern nebulizer solved all these
problems. The device is simply a cup with a mouthpiece on the top (or mask) and
oxygen tubing on the bottom. The tubing is connected to an air compressor. When
turned on, the air compressor provides a flow of air through a tiny hole in the
cup so that liquid inside the cup is drawn into the flow, causing a fine, white
mist.
In this way, the
nebulizer turns liquid into aerosols that are the perfect size for deposition
into the lungs once inhaled. This process is called atomization, and this is
why nebulizers used to be called atomizers.
Other names for
nebulizers are nebs, updraft therapy, nebulizer treatment or breathing
treatment. Most air compressors are compact and connect to a power source,
while newer ones are quite convenient and even portable as they can be plugged
into an outlet in your car.
For most asthmatics a simple inhaler is all
they need. Most asthma experts recommend every asthmatic carry an inhaler for
quick relief of asthma symptoms.
