Media richness theory. Media Richness Theory, sometimes referred to as information richness theory or MRT, is a framework used to describe a communication medium's ability to reproduce the information sent over it. It was introduced by Richard L. Daft and Robert H. Lengel in 1986 as an extension of information processing theory.
Albuterol and ipratropium is a combination bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Albuterol and ipratropium inhalation is used to prevent bronchospasm in people with chronic obstructive pulmonary disease (COPD) who are also using other medicines to control their condition.
Ipratropium bromide is available as a metered dose inhaler and is also available as nebules, which are used with a machine called a nebuliser. This converts the medicine inside the nebules into a fine spray which can then be inhaled through a face mask. Ipratropium bromide is also available as a nasal spray.
