Respiratory distress syndrome (RDS) (also know as Hyaline Membrane Disease): Usually baby’s lungs are kept open by a chemical, called surfactant that everyone has in their lungs. Some babies have less surfactant and the alveoli (small air sacs in the lungs) start to close up, making it really hard for baby to breathe. The baby develops RDS, that is, has increasing difficulty in breathing. Babies are ventilated and may be given artificial surfactant.

Respite: Regular breaks from caring for a family member. These breaks are often called respite, and the services that help you arrange breaks are usually called respite care services.

Retina: The back of the eye where blood-vessels supplying the light sensitive cells are located.

Retinopathy of prematurity (ROP): The abnormal growth of the blood vessels of the eye, seen in many premature infants. This happens because the blood vessels are not finished developing at the time of a premature infants birth. They have to finish developing outside the protected environment of the womb.

Suction: Aspiration of gas or fluid, usually from the lungs by mechanical means.

Supine: Describes the position of the baby, when lying on his back.

Supplementary: In addition to. Usually referring to adding vitamins and minerals to the baby’s diet, or complementing breast with milk formula feeding.

Surfactant: Compounds which line the air sacs (alveoli) of the lungs reducing surface tension and thereby preventing lung collapse on breathing out (expiration). Artificial or synthetic surfactant is now available for those infants who have difficulty producing their own shortly after birth. It is given to babies through the ventilator. Surfactants have names like Curosurf or Survanta.

It is often caused by fluid in the lungs and will improve as this fluid is absorbed. Some babies need oxygen as this resolves. TTN is often associated with cesarean delivery.

UTI: An abbreviation for urinary tract infection.

Umbilical Catheter, Arterial or Venous (UAC, UVC:): A tube inserted through the belly button (umbilical cord) into the arterial or venous blood vessels. Either tube is used to give the baby fluids and to draw blood samples. The UAC is used to monitor the baby’s blood pressure. If the baby requires oxygen therapy, the UAC will be used to draw blood gases and blood samples.

Ventilator: A machine which fills the baby’s lungs with air and helps the baby breathe. Also called a respirator.
