Editing Inhaler (section)

===Meter-dosed inhalers===

# The mouthpiece is removed and the inhaler is shaken for 5–10 seconds.
# The inhaler is gripped with mouthpiece on the bottom and canister on top.  A finger is placed on the canister to allow for delivery of medicine.
# Deep inhalation is done until no more air can be taken into the lungs. 
# Deep exhalation is done until most of the air is out of the lungs.
# Once deep exhalation is done, mouth is placed over mouthpiece.
# As the next deep inhalation begins, the canister is pressed down to release the medicine into the lungs.
# Slow deep breathing is continued and breath is held for 5–10 seconds, keeping the medicine in the lungs for a longer time period and preventing escape of aerosolized form of the medicine.
# Complete exhalation is done again. If multiple puffs of the medicine have to be taken, steps 1–5 are repeated after waiting for 15–30 seconds.
# Mouthpiece is replaced.<ref name=":0" />
