Glossary
Apnea - An absence of breathing (respirations).
Central apnea – No respiratory effort, caused when the brain fails to send the appropriate signals to
the breathing muscles to initiate respirations.
Obstructive apnea – Cessation of airflow into or out of the mouth or nose although efforts to breath
continue. Such obstructions may result from a spasm of the larynx, reflux, or other causes.
Bradycardia – Slowing of the heart rate below the age specified rate for 5 seconds or greater.
Cardiopulmonary Resuscitation (CPR) - A procedure used after cardiac arrest in which cardiac
massage, mouth-to-mouth resuscitation, and drugs are used to restore breathing.
Electrode - A conductor used to establish electrical contact between the monitor and the baby’s skin.
Electro Magnetic Interference (EMI) – Undesirable signals caused by electrical energy. When EMI
occurs at high frequencies, it is also called Radio Frequency Interference (RFI).
Functional Self-Test - A user-performed test to verify the SmartMonitor 2, patient cable, and lead wires
are working properly.
Heart rate – The number of heart beats per minute.
Impedance - The opposition offered by an electrical circuit to the flow of an alternating current, measured
by the ratio of the effective applied voltage to the effective current – This is the method used by
SmartMonitor 2 to detect respiration.
LA Connection - The opening on the patient cable marked LA is the connector for the black lead wire.
Modem - A device that allows the dealer or hospital to work with a monitor through telephone lines.
Oximeter – A photoelectric device that measures the amount of oxygen and other fluids in the blood. An
instrument that measures the oxygen levels in an enclosed controlled space such as an incubator or
bioreactor.
RA Connection - The opening on the patient cable marked RA is the connector for the white lead wire.
Respiration - The act of inhaling and exhaling air.
RL connection - Use of the third (green – RL) electrode and lead wire is normally not required, but may
help reduce excessive false low heart rate alarms.
Strain Relief Area - Located at the connecting tip of the lead wires or cables, this area has added
insulation surrounding the wires to prevent breakage when handled. This area is to be grasped when
removing lead wires.
