A NEC is due to the interference of blood supply to the intestinal mucosa. Necrotic
lesions occur at that site.
B ROP is thought to occur as a result of high levels of oxygen in the blood.
C BPD is caused by the use of positive pressure ventilation against the immature
lung tissue.
D IVH is due to rupture of the fragile blood vessels in the ventricles of the brain. It
is most often associated with hypoxic injury, increased blood pressure, and
fluctuating cerebral blood flow.
