RDS Complications | pheumothorax, infection or septicaemia, patent ductus arteriosus, intraventricular haemorrhage |
hypothermia leads too... | increased 02 and gluc consumption, decreased surfactant production |
hyperthermia leads too... | increased O2 consumption, fitting, renal failure, hepatic failure |

list the seven types of feeding | breast, cup, bottle, nasogastric, nasojejunal, gastrostomy, parenteral |

what tests would you carry out to diagnose infection | resp function->blood gases and x-ray, FBC, CRP, Blood cultures, urine microscopy and culture, lumbar puncture, cullture from tips of indwelling catheters |
what role does surfactant play | reduces surface tension in the alveoli which encourages gaseouse exchange |
