Indicators of effectiveness of circulatory, respiratory, neural, and endocrine body functions
PURPOSE OF VITAL SIGNS
• To assess current healthstatus of the patient
• To provide data to determine a patient’s usual
state of health.
• To have a baseline data (initial data when the
patient comes to ER)
Normal Blood Pressure
120/80
bradycardia
low pulse rate
tachycardia
high pulse rate
Normal Pulse Rate
60-100 bpm
Hypertension
Increase in blood pressure
Hypotension
Decrease in blood pressure
normal respiratory rate
12-20
TACHYPNEA
Increase in respiratory rate
BRADYPNEA
Decrease in respiratory rate
Hyperthermia
Increase in Temp
Hypothermia
Decrease in temp
Measuring vital signs is the nurse’s responsibility.
Know the patient’s usualrange of vital signs.
Know patient’s medical history, therapies, and prescribed medications.
Use an organized, systematic approach.
how often do we take vital signs?
Usually 2 hours, 4 hours, 3 hours
depends on the status of the patient
when the patient changesstatus
before doing procedures
pre and post blood transfusion
BODYTEMPERATURE
Difference between amount of heat produces by body processes and the amount lost to the external environment.
body temperature
Heat produced – heat loss
CORE TEMPERATURE
Temperature of deep tissues
SURFACE TEMPERATURE
Depends on blood flow to the skin and the amount of heat loss to the external environment.
FACTORS AFFECT THE BODY’S HEAT PRODUCTION.
Basalmetabolicrate
The rate of energy utilization in the body is required to maintain essential activities such as breathing.
FACTORS AFFECT THE BODY’S HEAT PRODUCTION.
MuscleActivity
Uncluding shivering increases the metabolic rate
FACTORS AFFECT THE BODY’S HEAT PRODUCTION.
Thyroxineoutput
It increases the rate of cellular metabolism throughout the body
FACTORS AFFECT THE BODY’S HEAT PRODUCTION.
Stress
It immediately increases the rate of cellular metabolism in many body tissues
FACTORS AFFECT THE BODY’S HEAT PRODUCTION.
Fever
increases the cellular metabolic rate and thus increases the body’s temperature further.
FACTORS AFFECTING BODY TEMPERATURE
Age
▪ Exercise
▪ Hormonallevel
▪ CircadianRhythm
▪ Stress
▪ Environment
▪ TemperatureAlterations
Infants
Greatly influenced by the temperature of the environment and must be protected from extreme changes.
OlderAdults
Sensitive to temperature extremes because of deterioration in control mechanisms, particularly poor vasomotor control, reduced sweat gland activity and reduced metabolism.
Increase metabolism- icrease heat production- increase body temperature
Women generally experience greater fluctuations in body temperature than men.
CIRCADIAN RHYTHM
Between 1:00-4:00 am: body temperature usually at its lowest
During the day, body temperature rises steadily to a maximum temperature value at about 4:00 pm
physical and emotional stress increases body temperature through hormonal and neural stimulation - increases metabolism - increase heat production
Warm room/ environment
Increased Temp
Cold room/ environment
decreased temperature
Fever/ Pyrexia
Heat loss mechanism are unable to keep pace with excessive heat production.
Important defense mechanism
Hyperpyrexia
High fever such as 41 degree
Intermittent fever
Body temp alternates at regular intervals between periods of fever and period of subnormal temperature
Remittent fever
Such as with cold or influenza, a wide range of temperature fluctuations occurs over a 24-hour period.
