Respiratory changes in pregnancy include an increase in tidal volume and minute ventilation, leading to a primary respiratory alkalosis. This chapter examines the various chest conditions arising in pregnancy—these include: amniotic fluid embolism—unique to pregnancy; venous air embolism—a rare condition that can occur in pregnancy; venous and pulmonary thromboembolism—pregnancy is a risk factor; pulmonary oedema—this can be caused by heart disease, as in the non-pregnant state, but it can also be associated with pre-eclampsia or HELPP syndrome and be induced by tocolysis; aspiration; varicella pneumonia—a potentially devastating complication of primary varicella-zoster virus infection; and influenza, which is associated with increased maternal morbidity. |
