Glossary of Terms

Anaemia: Too few red blood cells.

Apnoea: A pause in breathing for a short period.

Acidosis: An abnormally high level of acid in the blood.

Apgar Score: A way of assessing a the baby’s health immediately after birth, by scoring ‘points’ for heart rate, breathing, skin colour, tone and the baby’s reactions.

Asphyxia: Too little oxygen and too much carbon dioxide in the blood of the foetus or baby.

Aspirate: This term is used to obtain a small amount of the baby’s stomach contents via Nasogastric or Orogastric tube to ensure that the tube is in the stomach and it is safe for feeding.

Bilirubin: A pigment produced from the breakdown of red blood cells. When in excess, bilirubin appears as yellow skin known as jaundice.

Blood Gases: A blood test to check the level of oxygen, carbon dioxide and acidity.

Chronological Age: A baby’s age from the actual date of birth.

Corrected Age: The age a premature baby would be if he/she had been born on their due date.

Desaturations (Desats): Short periods of time when the oxygen level in your body's system drops below an accepted level.

Edema: Presence of too much fluid in body tissues causing a swollen appearance.

Endotracheal Tube: A tube inserted into the mouth to the windpipe to keep the airway open.

ECG (Electrocardiogram): A graph showing the heart’s electrical activity.

EEG (Electroencephalogram): A graph showing the brain’s electrical activity.

ECMO (Extracorporeal Membrane Oxygenation):This is a machine gives the blood oxygen from outside the body. It is used when treatment with a ventilator has not worked on babies with heart and lung problems.

Electrolytes: Essential substances in the body that, when dissolved, give solutions able to conduct electric current (for example table salt, sodium chloride or potassium chloride).

Extremely Low Birthweight: A baby born weighing less than 1000g.

Gestational Age: The time period in weeks from conception to delivery.

Glucose: Sugar.

Grunting: The noise made by a baby with breathing difficulty.

Grams To Pounds: Units of weight, 28 grams = 1 ounce, 454 grams = 1 pound.

Head Ultrasound: A diagnostic imaging technique that makes images of the brain and is generally done at the bedside.

Hypoglycaemia: Blood sugar level below normal.

Hypothermia: Body temperature drops below normal.

Hypoxia: Abnormally low amount of oxygen in the body tissues.

Humidity: To prevent premature babies losing too much water through their skin, they are often nursed in warm, humidified incubators. Humidity (water) is also added to the gases the baby breathes through the ventilator.

High Flow Cannula: A respiratory device that warms and humidifies high flow rates of air/oxygen blends for delivery to a baby via nasal cannula.

HDU: High Dependency Unit.

Incubator: A heated bed covered by a clear plastic box that allows the baby to be kept warm without clothes so that they can be monitored very closely.

Infusion Pump: Is like a syringe that provides fluids, medicine or nutrients directly into the blood. These can be given over a set period of time.

Intravenous Lines (IV): Are the fine tubes that are sometimes inserted into a blood vessel, usually in a hand, foot, arm or leg in order to give fluid or medicine directly.

Jaundice: Yellow colour in the skin from excess bilirubin.

Morphine: This drug is used for pain and to reduce the discomfort and stress that babies may experience from some of the necessary treatments being given.

MRI Scan: Computer-generated pictures of inside a baby without harming him or her.

Nasogastric Tube: A long, thin, soft plastic tube that is passed via a baby’s nose into his/her stomach. This tube is used to give milk to a baby until he/she is strong enough to take milk from the breast or a bottle.

Nasal Cannula: A small tube placed in your baby's nose to give extra oxygen to your baby.

NICU: Neonatal intensive care unit.

Nasojejunal Tube (NJ Tube): A soft, flexible tube inserted into the nose, through the stomach, and then into the jejunum (a part of the small intestines). The tube carries formula and medicines into the jejunum where it can be quickly absorbed into the body.

Oscillator: Is a type of ventilator that delivers very rapid breaths at a low pressure into the baby’s lungs. This can reduce the amount of damage to an infant’s fragile lungs compared to a conventional ventilator.

Orogastric Tube (OG Tube): A feeding tube that is placed into a baby's mouth and is advanced into his/her stomach. This tube may be used to feed or it may be used to remove air from the stomach.

P02: Blood oxygen level.

Patent Ductus Arteriosus (PDA): A blood vessel that allows blood to bypass the lungs. It should close shortly after birth.

pH: Amount of acid in the blood.

Phototherapy: Treatment of jaundice by use of special lights on the baby’s skin to breakdown the bilirubin.

Pulse Oximeter: A probe that wraps around a hand or foot, connected to a machine, which measures how much oxygen the blood is carrying.

Physiotherapy: Special exercises to improve or relieve physical problems.

Pneumothorax: When there is air between the lung and chest wall if a lung has leaked air.

Posset: When the baby spits up a small amount of milk after feeding.

PICC Line (Peripherally Inserted Central Catheter): A special intravenous catheter that is inserted into a peripheral (limbs) vein and threaded towards the heart. It is used for long term-fluid nutrition.

PICU: Paediatric Intensive Care Unit

Respiratory Distress Syndrome (RDS): Is a breathing problem that preterm babies can develop. It occurs because of a lack of surfactant in the lungs. The baby appears to breathe quickly (tachypnoea) and the chest appears to be sucked in when the baby breathes.

Resuscitate: This is to revive a baby.

Sepsis: Infection in the blood or other body tissues.

Suction: Mechanical removal of mucous from the nose or throat or endotracheal tube with a plastic tube.

SCBU: Special Care Baby Unit

Sleep Study: This is a test done on babies who have been on oxygen for a long time. The test establishes whether the baby can keep his or her own oxygen levels in a safe range.

Surfactant: A soap-like substance (made up mainly of fat) produced by lung cells. Surfactant Coats inner surfaces of airways and air sacs in the lungs to keep those passages open between breaths. Absent or lacking in the babies born preterm (production begins at about 24 weeks gestation but is not well developed until 36 weeks).

Stoma: Is an opening on the surface of the abdomen which has been surgically created to divert the flow of faeces to a pouch on the outside of the body.
