peak flow reading is 80-100% of the patients normal peak flow (under control), regular maintenance medication schedule is continued

6

what is a rescue inhaler

contains a different medication from maintenance inhaler. faster acting

9

10

what does it mean to have peak flow in the red zone?

measured peak flow is less than 50%. indicates bronchoconstriction. rescue inhaler must be taken immediately and a hospital visit may be required

11

what are the two types of inhalers for respiratory medication?

metered dose inhaler (MDI)
dry powder inhaler (DPI)

12
