Dictionary of Common Terms

This manual contains some terms that could be confused or can be used interchangeably. This section is
designed to increase understanding of its content. Note the following examples:
Alarm: may require user intervention, usually includes an audible beep or series of beeps
Alert: system information update, may consist of a text message on the display or an audible beep
AAP: American Academy of Pediatrics
Absolute humidity: pressure exerted by water pressure in the air, measured in mmHG (millimeters of
mercury) like blood pressure, independent of air temperature
ACOG: American College of Obstetrics and Gynecology
Apgar: named for Dr. Virginia Apgar. After birth, the infant is rated and assessed according to
Appearance, Pulse, Grimace, Airway, and Respiration
Apnea: cessation of breathing. Central apnea means the infant stops breathing. Obstructive apnea means
that something is preventing the infant from breathing
Average Db: decibel measurements smoothed to represent consistent sound measurement in the acoustic
environment (averaged over 1 minute)
Baby Mode: warmer temperature control mode whereby heater output is determined by baby
temperature via a skin temperature sensor attached to the baby's skin
NOTE:
Baby Mode, Skin Mode, and Servo Mode can be used interchangeably
Conduction: heat transfer between a surface colder or hotter than itself by direct contact
Convection: heat transfer due to warm or cold air currents
Core temperature: infant's internal temperature
Decibel (Db): numerical expression of the relative loudness of a sound
ELBW: Extremely Low Birth Weight, micro-preemie
Evaporation: conversion of a liquid to a vapor which causes thermal dissipation when body heat is
consumed by the process
Flow Rate and Flow Rate (LPM): flow meter, LPM = liters per minute as measured by a flow meter
Foot Candle: measurement of light and the relative illumination of a surface
Hyperthermia: patient is too hot (hyper = too much; thermia = heat)
Hypothermia: patient is too cold (hypo = not enough; thermia = heat)
Hypoxia: lack of oxygen
IR: infrared, primary method of heat gain from warmer heating elements
Keratin: component of epidermal skin layer in mature skin. Premature skin has lower levels of keratin in
the epidermal (outer) skin layer, which is why premature babies have higher evaporative heat losses. This
layer normally develops about 2 weeks after birth.
LBW: Low Birth Weight (term for premature babies)
Lux: measurement of light and illumination of a surface
