b'ChapterAsthma Medicine Delivery DevicesAsthma medications are generally taken by a hand-held inhaler device such as a puffer (metered dose inhaler) or dry powder inhaler (turbuhaler, rotahaler, accuhaler, aerolizer).It is recommended that a puffer be used in conjunction with a spacer to assist with fast andmore effective delivery of the reliever medication. A spacer is a plastic chamber that fits onto the puffer. The patient breathes slowly and deeplyafter activating the puffer.A spacer enables the patient to receive the maximum amount of medicine into theirlungs and helps overcome any coordination difficulty with relative ease.A spacer will ensure that the inhaled medication (both reliever and preventer) gets directly intothe airways.In the event of an attack, it is often difficult to coordinate the puffer and inhale the medicine. It is important to use the puffer properly to effectively control asthma.Puffer alone Puffer with spacer180 Medical Emergencies'
