Vital Signs Flashcards
Sphygmomanometer
Blood pressure cuff used to measure blood pressure
Hypertension
High blood pressure
Systolic reading constantly above 140 or a diastolic reading constantly above 90
What are the 6 vital signs?
- Blood Pressure
- Temperature
- O2 Sat
- Pulse
- Respiration
- Pain
Stroke Volume
The amount of blood ejected from the heart in one contraction
Cardiac Output
The volume of blood pumped from the heart in a full minute
Arteriosclerosis
The hardening of arteries
Systolic Pressure
Measurement of the force exerted by the blood against the walls of arteries during contraction of the heart ventricles;
When the pressure is the highest
Systole
Time during which the ventricles are contracted
Diastolic Pressure
Measurement of the pressure exerted by the blood on the artery walls while the heart ventricles are not contracting;
When the pressure is the lowest
Diastole
Time during which the ventricles are at rest
Pulse Pressure
Measurement of the difference between the systolic and diastolic pressures.
Normal Range: 30-50
Prehypertension
When the systolic pressure rises above 120
Korotkoff’s Sounds
sounds heard over an artery during cuff deflation representing the blood flow.. (5 sounds)
Auscultatory Gap
Silence and the return of sounds when checking blood pressure
Primary Hypertension
The rise in blood pressure that results
Secondary Hypertension
When there is renal or endocrine disease process that results in elevation of blood pressure
Hypotension
When blood pressure suddenly falls 20 mm Hg to 30 mm Hg below the patient’s normal range or falls below the low normal of 90/60
Orthostatic Hypotension
When position changes result in a systolic pressure drop of 15 to 20 mm Hg or the diastolic pressure falls 10 mm Hg
Modified Trendelenburg Position
Supine position in which the feet are elevated above the level of the heart;
Initial treatment for when a patient becomes faint due to hypotension
Basal Metabolic Rate (BMR)
The amount of heat that produced by the body when at total rest
Thermoregulation
Regulation of body temperature
Hypothalamus
Part of the brain that controls the thermoregulation
Diaphoresis
When sweat production is high enough to be seen on the skin
Circadian Rhythm
The body’s “time clock” or rhythm of it’s own
Tympanic Thermometer
Infrared device used with a disposable cover over the tip of the speculum.
Used to measure body temperature in the ear
Febrile
The state of having a fever
Afebrile
The state of being without fever
Hyperthermia
Serious elevation of a body temperature above 105 degrees
