What are 2 methods to induce cough in a human or laboratory animal?

Hello,

One method which was studied was to induce coughing using a citric
acid aerosol inhaler (see link below). Another method which is quite
remarkable is using magnets placed on a person's back to induce
coughing, even in patients who are paralyzed from the neck down (see
link below).

Administer a 2 cc sterile water "breathing treatment" via nebulizer or
ultrasonic nebulizer.  This is a commonly utilized procedure used to
induce a sputum specimen.

Some physicians prefer to administer just a "normal saline" breathing
treatment instead.

Aerosolized sterile water can induce bronchospasm so do not do this
without a physician prescription and the requisite medical support to
reverse a potentially life-threatening bronchospasm.
