Dyspnea and PE Flashcards
What is defined as the subjective experience of breathing discomfort that consists of qualitative distinct sensations that vary in intensity?
Dyspnea
What 3 things should aberrations of the respiratory system be considered in the context of?
a controller
ventilatory pump
gas exchanger
What is the consequence of interactions between the efferent output to the ventilatory muscles, the afferent input from receptors throughout the body, and the processing of information occurring in the brain?
Respiratory sensations
Disorders of what are associated with the increased work of breathing or a sense of increased effort?
Ventilatory pump
What receptor is activated by hypoxia, academia, and acute hypercapnia and leads to increased ventilation and air hunger?
Chemoreceptors
What receptor is stimulated by bronchospasm that produces chest tightness?
Mechanoreceptors
What is associated with a sensation of inability to get a deep breath?
Hyperinflation
What leads to hyperventilation due to increased activity?
the Controller
A disorder to what leads to an increased airway resistance and work of breathing while hyperinflation further increasing the problem?
Ventilatory pump
What 2 syndromes cause an increased effort to breathe due to weakness of the muscles?
Myasthenia gravis and Guillian-Barre syndrome
What kind of output of the cardiovascular system when Dyspnea is in relation to situation such as anemia and hyperthyroidism?
High output
What kind of output of the cardiovascular system Dyspnea are in relation to deconditioning, hypertension, cardiomyopathy, and obesity?
Normal output
What kind of output of the cardiovascular system Dyspnea are in relation to disease of the myocardium resulting from CAD and LV failure?
Low output
What pressures do the extent at which fluids accumulate in the interstitium depend on?
hydrostatic and oncotic pressure
Which pressure favors the movement of fluid out of the capillaries?
Hydrostatic pressure
