Thank you for providing this information. It is difficult to know how much medication is left in an inhaler-type pump. The best way is to keep track of the number of doses taken from the pump since purchase. Additionally, you can try the trick of dipping the medication bottle into water to see if it still contains medication, although this is not very reliable. The orange pump should improve your child's condition in a few days. If not, it is best to go back to the doctor. Additionally, make sure to use the pump with the mask correctly, as demonstrated in the video. If you need anything else, please do not hesitate to come back and consult us. We look forward to seeing you.
