An asthma inhaler works most effectively if you deliver your medication slowly, so this is where a spacer device can be useful to help you achieve this goal. Many people using metered dose ...
Metered-dose inhaler (MDI); the mouthpiece slots into the back of the spacer.. To use an inhaler without a spacer requires coordinating several actions in a set order (pressing down on the inhaler, breathing in deeply as soon as the medication is released, holding your breath, exhaling), and not everyone is able to master this sequence.
MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...
Recent evidence shows that nebulizers are no more effective than metered-dose inhalers (MDIs) with spacers. [5] An MDI with a spacer may offer advantages to children who have acute asthma. [3] [6] [5] Those findings refer specifically to the treatment of asthma and not to the efficacy of nebulisers generally, as for COPD for example. [5]
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies ...
The post bronchodilator test (Post BD), also commonly referred to as a reversibility test, is a test that utilizes spirometry to assess possible reversibility of bronchoconstriction in diseases such as asthma.
The main contraindication for ipratropium in any form is hypersensitivity to atropine and related substances. [20] [21]Conditions such as narrow-angle glaucoma, prostatic hyperplasia, or bladder neck obstruction are not necessarily contraindicators, but should be taken into account, particularly if the patient is receiving an anticholinergic by another route.
