Since the drug particles in the inhalation device are usually very small and odorless, the patient may not feel that the drug has been inhaled. However, as long as the inhalation method is correct, the drug can be effectively inhaled into the lungs. If you suspect that there is no drug in the inhalation device, you can use the black cloth experiment to prove it: cover the mouth of the inhalation device with a piece of dark thin cloth, inhale the drug according to the correct usage steps, and then open the thin cloth. If there is white powder on the dark thin cloth, it can be proved that the drug has been inhaled, indicating that the operation is correct. |
