Body Temperature, Pulse Rate, and Heart Rate Flashcards
Cardinal signs that provide quantitative measures of the status of the cardiovascular and pulmonary system
Vital Signs
Indication of degree of heat within the body
Body Temperature
A palpable wave of blood is produced in the walls of the arteries with each heartbeat.
Pulse
The act of breathing
Respiration
It refers to the force the blood exerts against a
vessel wall.
Blood Pressure
Subjective perception of noxious stimuli.
Pain
Absence of oxygen in the tissues
Anoxia
The pulse that is found when a stethoscope is placed on the chest wall over the apex of the heart; also may be found by palpation.
Apical Pulse
The absence of breathing
Apnea
Variation from the normal rhythm
Arrhythmia
Listening for sounds produced within the body by using the unaided ear or a stethoscope.
Auscultation
A slow heartbeat (i.e., pulse rate less than 60
beats/min); may be a normal finding in a well-conditioned person or an abnormal finding
Bradycardia
The amount of blood that is pumped from the
heart during each contraction.
Cardiac Output
Profuse perspiration.
Diaphoresis
The period when the least amount of pressure is exerted on the walls or the arteries during the heartbeat; usually indicates the resting phase of the heart.
Diastole
Labored or difficult breathing
Dyspnea
Sounds are heard during auscultatory determination of blood pressure.
Korotkoff’s Sounds
It is believed to be produced by the vibratory motion of the arterial wall as the artery suddenly distends when compressed by a pneumatic blood pressure cuff; the origin of the the sound may be within the blood passing through the vessel or within the wall itself
Korotkoff’s Sounds
Indicators of physiologic status and the body’s response to physical activity, environmental conditions and emotional stressors.

ABNORMALITIES IN BODY TEMPERATURE
- Pyrexia
- Hyperpyrexia
- Pyrogens
- Signs and Symptoms of Fever
elevated body temperature
Pyrexia
pyrogens (fever producing substances)
Hyperpyrexia
Pyrogens came from _______ that leads to what?
- Toxic Bacteria
- Fever
Increased pulse, respiratory rate, chills, malaise, chills, sweating, disorientation, confusion, convulsions, coma
Signs and Symptoms of Fever
STAGES OF FEVER
- Prodromal Phase
- Invasion or onset
- Stationary
- Defervescence
- Crisis
- Lysis
Prior to temperature elevation
Prodromal Phase
Gradual or sudden rise until maximum temperature reached
Invasion or onset
Point of highest elevation reached and sustained
Stationary ( fastigium or stadium course)
Fever subsides
Defervescence (termination or resolution)
Sudden drop in temperature
Crisis
A gradual drop in temperature ( sweating is
initiated )
Lysis
Common Types of Fever
- Continuous
- Intermittent
- Relapsing
- Remittent
Also known as constant or sustained. Body temperature is constantly elevated above normal throughout day but does not fluctuate by more than 1.8 degrees Fahrenheit in 24 hours.
Continuous Fever
This type of fever is seen in uncomplicated minor infection, UTI, lobar pneumonia, typhoid, infective endocarditis, and thypus.
Continuous Fever
The body temperature alternates between periods of fever for some hours of the day with return to normal temperature for the remaining hours.
Intermittent Fever
This type of fever is seen in malaria and septicemia.
Intermittent
This is also known as recurrent or periodic fever. Periods of fever are interspersed with normal temperature; each last at least one day.
Relapsing Fever
This type of fever is seen in non-infectious inflammatory diseases such as rheumatoid arthritis and Chron’s disease.
Relapsing Fever
Elevated body temperature throughout the the day fluctuates more than 3.6F (2C) within 24 hours but never returns to normal.
Remittent Fever
This type of fever is seen in infective endocarditis and typhoid infection.
Remittent Fever
Result of exposure to extreme cold temperature
Hypothermia
Prolonged exposure to cold leads to a decrease in metabolic
rate and body temperature → heat regulatory
and protection mechanism is lost
Hypothermia
DEPRESSION OF THERMOREGUALTORY CENTER (brain cooling)
Hypothermia
IMPAIRED FUNCTION OF THERMOREGULATORY CENTER of Hypothermia
34.4 degrees celcius
NO FUNCTION OF THE THERMOREGULATORY CENTER of Hypothermia
29.4 degrees celcius
Symptoms of hypothermia:
- Decreased pulse
- Decreased respiratory rate
- Cold and pale skin
- Cyanosis
- Decreased cutaneous sensation
- Drowsiness → coma
- Depression of mental and muscular responses
