Arterial hypoxemia Laryngeal edema
The onset of the signs and symptoms of amniotic fluid embo- lism are dramatic and abrupt, classically manifesting as dyspnea, arterial hypoxemia, cyanosis, seizures, loss of con- sciousness, and hypotension that is disproportionate to blood loss.
As a result, pulmonary artery pressures increase, arterial hypoxemia develops owing to ventilation/perfusion mismatching, and hypotension occurs, reflecting decreased cardiac output and congestive heart failure caused by right ventricular outflow obstruction and acute right heart failure.
Conversely, fetal distress resulting from arterial hypoxemia, acidosis, or central nervous system damage is associated with minimal to absent beat-to-beat variability.
results in large right-to-left intracardiac shunts with associated arterial hypoxemia and acidosis.
