<unk>  is distinguished from shortness of breath or dyspnea, which is the sensation of respiratory distress rather than a physical presentation. Still, many simply define dyspnea as difficulty in breathing without further specification, which may confuse it with e.g.<unk>  or tachypnea (rapid breathing).<unk>  has occasionally been included in the definition of dyspnea as well. However, in the standard definition, these related signs may be present at the same time, but do not necessarily have to be. For instance, in respiratory arrest by a primary failure in respiratory muscles the patient, if conscious, may experience dyspnea, yet without having any<unk>  or tachypnea. The other way around,<unk>  or tachypnea can voluntarily be performed even when there is no dyspnea.
