Partikel size: Particles > 10 microns deposit in the oropharynx. The single most important device factor determining the site of aerosol deposition is particle size. Devices for delivering therapeutic aerosols generate particles with aerodynamic diameters from 0.5 to 35 microns. In asthma, the airways, not the alveoli, are the target for delivery. Particles > 10 microns deposit in the oropharynx. Particles 5-10 microns deposit in the trachea and large bronchi. articles 1-5 microns in size reach the lower airways Particles <0.5 microns act as a gas and are exhaled.

Metered-dose Inhaler (MDI)
Metered-dose Inhaler (MDI) Ketika tabung ditekan metering katup satu arah dibuka oleh mekanisme pemicu dalam tubuh aktivator. Obat disemprotkan dekat pembukaan corong dan kemudian pasien dapat menghirupnya. Aerosol terdiri dari droplet-droplet dalam berbagai diameter. Ketika obat dihirup, droplet ukuran besar terdeposisi di mulut, faring, dan laring, sedangkan droplet dengan ukuran yang lebih kecil dapat masuk kedalam saluran pernafasan bawah.

CLEANING YOUR MDI 5. In the morning, put the canister back inside the mouthpiece and put the cap on the inhaler. 1. Clean your inhaler mouthpiece about once a week or as often as recommended by your doctor or pharmacist. In addition to your routine cleanings, clean your inhaler if little or no medication is sprayed when you activate the inhaler. 2. Remove the metal canister from the L-shaped plastic mouthpiece. 3. Rinse only the mouthpiece and cap with warm running water for about 30 seconds. Do not wash or put the canister in water. 4. Let the mouthpiece and cap dry overnight. (2) 12 12

SPACER for children ....
Spacer harus dibersihkan sebelum digunakan terlebih dulu dan kemudian setiap bulan dicuci dalam air hangat dengan deterjen dapur serta dikeringkan dengan udara tanpa pembilasan. Pengeringan dengan kain atau handuk kertas dapat mengakibatkan muatan elektrostatik ('statis') di bagian dalam spacer, yang dapat mengurangi ketersediaan dosis. Mouth-piece harus dibersihkan dari deterjen sebelum digunakan. Spacer harus ditinjau setiap 6-12 bulan untuk memeriksa struktur utuh (misalnya tidak ada retak) dan katup berfungsi. (National Asthma Council Australia, 2008)

Shake the inhaler and remove the inhaler cap Shake the inhaler and remove the inhaler cap. Check the inhaler instructions to see if you need to prime your inhaler before you use it. If it needs priming, follow the instructions on how to prime your inhaler.
Place the mouthpiece of the inhaler into the spacer.
Remove the cap from the spacer.
Hold the inhaler upright with the mouthpiece at the bottom.
Tilt your head back slightly and breathe out slowly and completely.
Place the spacer's mouthpiece in your mouth.
Press down on the inhaler to spray one puff of medicine into the spacer and then start breathing in slowly (press first, then breathe in).
Hold your breath for 10 seconds, to give the medicine time to settle in your lungs. If you need to take a second dose, wait 30 to 60 seconds to allow the inhaler valve to refill.
