A study maximum inhaler parameters and characteristic between normal and respiratory problem related patient

Abstract

Metered Dose Inhalers (MDI) is used to prevent and relieve the symptoms and progression of certain diseases (asthma, chronic obstructive pulmonary disease, cysticfibrosis and bronchiectosis) by delivering the inhaled pharmaceutical aerosols (IPA) to the desired area. The MDI is easily can be placed in a pocket or purse and ready to be used instantly and these are reasons why it is used widely. The spacer was used to avoid deposition of most IPA on the mouth throat area whereby it promotes the expansion and mixing of the IPA before it is inhaled. However, the IPA inhaling efficiency using MDI is relatively low compare to other methods. A study on the effect of various motor rotational speeds , various type of fan and the design of inhaler system will carry out to understand their effect on the IPA fluid dynamics characteristics. The Pyrometer and Radioaerosol x-ray testing will be conducted to related patients to analyze the flow characteristics inside the body of patients. The expected results should show that the alternative inhaler system and the characteristics of air flow will give a better delivery of the IPA.
