The Hierarchy of Needs. The Maslow motivation theory is one of the best known and most influential theories on workplace motivation. Psychologist Abraham Maslow first developed his famous theory of individual development and motivation in the 1940âs. He suggested that human beings have a hierarchy of needs. That is, that all humans act in a way which will address basic needs, before moving on to satisfy other, so-called higher level needs.
Diseases in other organs, such as the kidneys and the liver, may cause dyspnea by a combination of the interactions we have discussed. In end stage renal disease, for example, dyspnea can be due to metabolic acidosis, volume overload causing pulmonary edema, and/or pleural effusions impairing lung expansion.
Respiratory muscle weakness should be considered in patients whose dyspnea cannot be explained by pulmonary disease, cardiac disease, anemia, or deconditioning.First symptoms may occur when respiratory muscles are under increased load, such as when standing in deep water, swimming, or in the supine position.yspnea is common in advanced stages of neuromuscular disorders, but it is infrequently the presenting symptom. However, dyspnea is a frequent complaint in a primary care setting but is rarely caused by a respiratory muscle weakness.
