What do all those NICU Terms mean?
A’s and B’s: These are often the abbreviations for Apnea & Bradycardia they refer to periods of slower breathing and a slower heart rate.
Anemia: A condition in which the red blood cells in the blood, measured by hematocrit, are lower than desired. Red blood cells carry oxygen and carbon dioxide to and from the tissue.
Apnea: A prolonged pause in breathing that lasts more than twenty seconds. This is a common problem in premature infants and requires monitoring and sometimes medication.
Aspiration: Inhaling a foreign substance into the lungs, such as milk, stomach fluids, meconium or amniotic fluid.
Attending Physician: The doctor who has the primary responsibility for coordinating the care for your baby. In the NICU this is usually the Neonatologist.

"Blow by”: A slang term often used in the NICU meaning, to give a baby a small amount of oxygen through a tube pointed towards the nose.
Bilirubin: A yellow-pigmented waste product that forms when the body naturally eliminates old red blood cells. It may make the skin and eyes look yellow. In premature infants, they are often put under fluorescent light or on a bili blanket to help the levels come down. (also refer to jaundice)
Blood gas: A blood test used to evaluate an infant’s level of oxygen, carbon dioxide, and acid. This helps to assess an infant’s respiratory status. This test is done by a heel stick, blood is taken from the umbilical catheter or from the artery near the wrist.
Blood pressure: The pressure of the blood in the arteries with each pulsation of the heart.
Bradycardia (Brady): A slowing of the baby’s heart rate.
Cardiologist: Is the Doctor who specializes in the heart and circulation
Chem strip: (blood sugar or dex stick): Testing of the baby’s blood sugar level.
Case Manager: A staff member who interfaces with insurance agencies regarding medical necessity and length of stay, as required, helps with discharge planning, arranging for medical equipment and visiting nurses when necessary. Many insurance companies also have CASE MANAGERS who are assigned to customize and individualize benefits for those with extensive or complex health care needs.
Central Catheter or Central Line: A thin, flexible tube (catheter) placed in a larger vein or artery to deliver medications or necessary fluids and nutrients to the body. Broviac catheters are usually placed in the upper chest and tunnel under the skin to enter the vena cava, the large blood vessel in the center of the body carrying blood to the heart. PICC lines (percutaneously inserted central catheters) are usually threaded through a vein in the arm to the vena cava. Central catheters also include umbilical venous and umbilical artery catheters which may be inserted into the vein or artery of the umbilical stump (belly button) shortly after birth.
Chemstrip: A test in which a drop of the baby's blood is placed on a strip of special paper to determine the amount of sugar in the blood.

CT Scan: A digital x-rays which show the size and position of many parts of the brain. A CT scan also can be done on other parts of the body. The baby must go to another area of the hospital to have a CT scan.
Culture: A laboratory test of blood, spinal fluid, urine, or other specimens which shows if germs are present and which ones they are.
Cyanosis: Blueness of the skin as a result of decreased oxygen levels.
"De-satting" or desaturation: A drop of oxygen levels in the baby’s bloodstream.
Differential: A test which divides the white blood cell count (from the CBC) into several categories, chiefly: "polys" (short for polymorphonuclear leukocytes), "bands" (immature "polys"), "lymphs" (lymphocytes), "monos" (monocytes), "cos" (eosinophils), "basos" (basophils). The percentages of each cell type may vary in different kinds of infections; for example, polys and bands usually will predominate in bacterial infections, while the number of lymphs usually will increase in viral infections.
Echocardiogram: A test done to look at the heart using sound waves through the chest wall. This is much like an ultrasound done during pregnancy and is neither harmful nor painful.
Edema: Is referring to "Puffy" skin which is caused by a build-up of fluid in body tissues.
Endotracheal tube (ET tube): A tube that passes through either the baby’s mouth or nose into the windpipe (trachea) to allow oxygen into the lungs.

Gastrostomy: A surgically created opening in the abdominal wall to provide nutrition directly into the stomach.
Gavage feedings (tube feedings or NG- nasal gastric tube): A way of providing nutrition through a plastic tube passed through the baby’s mouth or nose and into the stomach.
Head Ultrasound (HUS): A painless test that uses sound waves to look at a baby’s brain. This test can be done at the bedside in the NICU.

High-Frequency Oscillatory Ventilator: A special ventilator capable of breathing for a baby at rates exceeding those of a regular ventilator.
Hypotension: Low blood pressure.
Humor: Is something you used to have before your baby was in the NICU. Don't lose your sense of humor, it will help you get through these difficult times.
Hypoglycemia: When your baby has a low amount of sugar (glucose) in the blood.
Inspiratory Time: Is the length of a forced breath provided to the baby by a ventilator.
Intravenous (IV) therapy: Nutrition or medication given through a catheter that is inserted into a vein
Intubation: Inserting a tube into the trachea (windpipe) through the nose or mouth to allow air to reach the lungs.
"I’s and O’s”: A slang abbreviation often used in the NICU meaning, the amount of fluid, (IV and feeds) baby takes in compared to how much the baby pees and poops out.
Isolette or incubator: A type of enclosed bed for an infant who is not mature or well enough to maintain her body temperature in an open crib.

Nasal cannula: Small prongs placed in the baby’s nose that delivers oxygen
Necrotizing Enterocolitis (NEC): An infection of the wall of the intestines, which may spread to the blood. Premature babies are particularly vulnerable to this disease. Surgery is sometimes necessary to remove the damaged intestine, and the baby may need prolonged feeding by vein until he recovers.

Ophthalmologist: A medical doctor who specializes in disorders of the eye.
Otolaryngologist: A medical doctor who specializes in the ear, nose, and throat.
Patent Ductus Arteriosus (PDA): A small vessel which allows blood to bypass the lungs. This vessel is open while the baby is in the womb but closes typically shortly after delivery. If the vessel fails to close on its own, particular medication or surgery may be needed.
Pneumothorax: A collapsed lung- the collection of air in the space around the lungs. This buildup of air puts pressure on the lung so it cannot expand as much as it usually does when you take a breath.
Pediatrician: A medical doctor who specializes in infants and children.
PICC line (Peripherally inserted central catheter) ): A PICC is a line inserted through a vein and then advanced through increasingly larger veins, toward the heart. Used when IV therapy, antibiotics, or nutrition (TPN/lipids) are administered for an extended period of time.

Becoming familiar with these A, B... W’s (apnea, bradycardia, wean) will help you better understand your baby's journey through the NICU. You will soon, not only be accustomed to the lingo, but you too will be speaking this new found language with ease. With that new found knowledge please always remember the one in the middle that starts with H (humor) it will be necessary and needed at times.
