Breathing is a critical component of respiration‚ a process in which life sustaining oxygen is delivered to all the cells in the body and carbon dioxide is removed and released into the air. Breathing difficulties are symptoms of a variety of mild to serious underlying disorders‚ diseases and conditions that interfere with normal respiration and breathing. Hence‚ the ability to carry out and document a full respiratory assessment is an essential skill for all nurses. While conducting the assessment

In every chemical reaction‚ the starting materials (the substrate(s) in the case of enzymes) can take many different paths to forming products. For each path‚ there is an intermediate or transitional product between reactants and
