The presentation is the following: * Anxiety, restlessness, altered mental state due to decreased blood flow to the brain and subsequent hypoxia. * Low blood pressure due to decrease in cardiac output. * A rapid, weak, thready pulse due to decreased circulation combined with tachycardia. * Cool, clammy, and mottled skin (cutis marmorata) due to vasoconstriction and subsequent hypoperfusion of the skin. * Distended jugular veins due to increased jugular venous pressure. * Oliguria (low urine output) due to inadequate blood flow to the kidneys if the condition persists. * Rapid and deeper respirations (hyperventilation) due to sympathetic nervous system stimulation and acidosis. * Fatigue due to hyperventilation and hypoxia. * Absent pulse in fast and abnormal heart rhythms. * Pulmonary edema, involving fluid back-up in the lungs due to insufficient pumping of the heart.
