Before entering the lungs, oxygen from the air is warmed and moistened when it passes through the nose and mouth. When a child has a tracheostomy, this does not occur. Therefore, humidity is replaced with a tracheostomy collar or disposable humidity device such as the Breathaid or Humidivent.
Humidity also loosens secretions present in the trachea.
Disposable humidity devices should not be used if your child is receiving oxygen. Sometimes it will be necessary to count the number of times your child breathes per minute. This is called the respiratory rate. To count, you will need a watch or clock with a second hand. Place your hand on your child's chest and when the second hand reaches the 12, begin counting each time your child breathes.
