The Junghua Dam and reservoir on the Dahan Creek in Taoyuan City, Taiwan. A reservoir (etymology: from French rÃ©servoir a storehouse ) is a storage space for fluids. These fluids may be water, hydrocarbons or gas. A reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water. Reservoirs can be created by controlling a stream that drains an existing body of water.
There are significant differences between Albuterol and Symbicort inhalers. Symbicort is an inhalant corticosteroid that works as a dilator on the lungs and airways. It works in two ways: reducing inflammation (one of the leading causes of asthma attacks), and also helps to open the airways, thus improving the percentage of the airflow quality in a patient. Albuterol is used only as a rescue inhaler for asthmatic patients. It works by relaxing the muscles in the airways and spasms that are a side effect of an asthma attack. Albuterol is not used to prevent asthma attacks; it only works effectively when treating an asthma attack. Therefore, it should be used on an as needed basis. Symbicort is a preventative and maintenance inhaler for asthmatic patients.Reference: www.drugs.com
Albuterol MDI is the preferred formulation in most cases and contains 90 Âµg/puff and 200 puffs/canister. Recommended dose is 2 puffs every 4-6 hours as needed. Severe exacerbation may require up to 4 inhalations every few hours. It may be used with ipratropium to obtain better effect.
