Chapter 15 (Vital Signs) Vocab Flashcards
Afebrile
free from fever
Antipyretic
medication that reduces fever
Apical Pulse
a pulse site on the left side of the chest over the pointed end, or apex, of the heart
Apnea
the lack of respiratory movements
Core Temperature
temperature of deep tissues
Disphoresis
excessive sweating
Bradypnea
respiratory rate less than 12 per minute or lower than acceptable limits
Capillary Oxygen Saturation
SpO2 - the estimate of the amount of oxygen in the blood
Febrile
marked or caused by fever : feverish
Fever
raised body temperature
Heat Stroke
dangerous emergency defined as a body temp 40.2 C or 104.4 F or more
Hypertension
an often asymptomatic disorder characterized by persistently elevated blood pressure
SBP is greater than 140 mm HG and DBP greater than 90 mmHG
Dysrhythmia
an abnormal rhythm of the heart; where a regular interval is interrupted by an early beat, late beat, or missed beat; can be regularly irregular or irregularly irregular
ETCO2 Monitoring
a monitor that attaches directly to the ventilator system and measures the exhaled carbon dioxide through sensors
Eupnea
the normal rate and depth of ventilation
Infrared Thermometer
relies on thermal radiation to measure body temp
EX: tympanic membrane thermometer
Korotkoff Sound
arterial sounds heard through a stethoscope applied to the brachial artery distal to the cuff of a sphygmomanometer that change with varying cuff pressure and that are used to determine systolic and diastolic blood pressure
Orthostatic Hypertension
a reduction of SBP of at least 20 mm HG or a reduction of DBP of at least 10 mmHG within 3 minutes of quiet standing
Pulse Deficit
An inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse site
Pulse Pressure
the difference between the SBP and DBP
Pyrexia
raised body temperature; fever
Sphygmomanometer
a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, and a mercury or aneroid manometer to measure the pressure
Systolic Pressure
the pressure of the blood in the arteries when the heart pumps; the peak pressure
Tachycardia
abnormally elevated heart rate more than 100 BPM
Nonshivering Thermogenesis
defined as an increase in metabolic heat production that is not associated with muscle activity. It occurs mainly through metabolism in brown fat. Typically in babies.
Ventilation
the mechanical movement of gases into and out of the lungs
Oxygen Saturation
the fraction of oxygen-saturated hemoglobin relative to total hemoglobin in the blood
Perfusion
the distribution of red blood cells to and from the pulmonary capillaries
Tachypnea
respiratory rate or more than 20 per minute or greater than acceptable limits
