Based on your child's history and the severity of asthma, his or her doctor will develop a care plan, called an "asthma action plan." The asthma action plan describes when and how your child should use asthma medications, what to do when asthma gets worse, and when to seek emergency care for your child. Make sure you understand this plan and ask your child's doctor any questions you may have.
Your child's asthma action plan is important to successfully controlling his or her asthma. Keep it handy...
Recording this information will help you recognize asthma attacks and head them off before you become seriously ill. Your doctor will also use this diary to evaluate how well your asthma action plan is working.
If the highest PEF reading is less than 80% of your personal best, you must follow the instructions given by your health care provider in your asthma action plan. Also remember to check PEFs more frequently that day, including an evening PEF.
