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: requires user intervention, usually includes an audible beep or series of beeps
APGAR: named for Dr. Virginia Apgar. After birth, the infant is rated and assessed according to
Appearance, Pulse, Grimace, Airway, and Respiration
Baby Mode: temperature control mode where baby temperature, measured by a skin probe attached to
the patient skin, determines heater output
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 internal temperature
Decibel (dB): numerical expression of the relative loudness of a sound
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
GMDN: Global Medical Device Nomenclature
Hyperthermia: patient is too hot (hyper = too much; thermia = heat)
Hypothermia: patient is too cold (hypo = not enough; thermia = heat)
I:E: Inspiratory:Expiratory
Manual Mode: warmer temperature control mode where clinicians determine the heater output to the
infant manually
Notification tone: system information update, consists of a text message on the display or an audible
beep
Pre-Warm mode: Pre-Warm mode is typically associated with radiant warmers. The system activates the
overhead heaters at 100% for 3 min. Then it reduces to 60% for 12 min, and then reduces again to 30%.
Thus, when the patient is admitted to the bed, it is already warm and the heating elements can respond
quickly to clinician or patient requirements.
Relative Humidity (RH): amount of water vapor present in the air, expressed as a percentage and
temperature dependent
Radiation: heat transfer to a warm or cold surface NOT in contact with the surface
Servo Mode: closed loop systems that automatically maintain set levels based on feedback to a source.
For example, Baby mode temperature control is a servo system that controls heat processes to the patient
based on infant temperature.
NOTE:
Baby Mode, Skin Mode, and Servo Mode can be used interchangeably
