Vital Signs

What are the six vital signs? Temperature, pulse, respiration, blood pressure, O2 saturation, and Pain
Heat produced - Heat Lost = ? Body Temperature
Lowest Temperature occurs at 6AM
Highest temperature occurs at 4PM
Temperature during ovulation does what? Raises
What hormone controls body temperature? Hypothalamus
Widening of blood vessels Vasodilation
Narrowing of blood vessels Vasoconstriction
Rate at which body uses energy while at rest to keep vital functions going Basal Metabolic Rate (BMR)
Heatloss without physical contact Radiation
Heatloss with direct contact(tepid water) Conduction
Heatloss with air movement Convection
Heatloss involving change of liquid to gas (sweating, fogging up window) Evaporation
What hormones influences BMR? Thyroid hormone and Epinephrine/Norepinephrine
What causes shivering? Vasoconstriction
What is diaphoresis? Excess sweating
T/F Newborns and older adults lose heat easily True
T/F Exercise increases temp True
Circadian rhythm, stress, environment, fluid intake, infection, age Factors that influence Temperature
Fever caused by pyrogens Hyperpyrexia
Normal temperature level that is not harmful 102.2 F and below 104 in children
Pyrexia/ Febrile Fever
Fever effects? Metabolism increases O2 increases Water loss
Heat stroke; hot dry skin; can't sweat; heat exhaustion hypErthermia
frostbite/ extreme chill HypOthermia
Indirect measure of cardiac output Pulse
Stroke Volume 70 ml
Cardiac output = Stroke volume X Pulse
What system is pulse influenced by? Autonomic Nervous system
Parasymmpathetic causes heart rate to decrease
sympathetic causes heart reat to increase
+3 Pulse Bounding
+2 Pulse Regular
+1 Pulse Weak
0 No pulse
Bradycardia Pulse <60bpm
Tachycardia Pulse >100bpm
Early/Late Beat Dysrhythmia
Difference between radial and apical pulse Pulse deficit
How long is the apical pulse felt for? 1 full minute
Where is the apical pulse located? 4-5 Intercostal space, left sternal border
Constant body temperature continuously above 100.4F - little fluctuation Sustained
Fever spikes mixed with usual temperature leves; temp returns to acceptable value at least ONCE in 24 hours Intermittent
Fever spikes and falls without a return to acceptable temp levels Remittent
Periods of fever episodes mixed with acceptable temp values, sometimes longer than 24 hours Relapsing
120 -160 BPM Infant Heart Rate
90 -140 BPM Toddler Heart Rate
80-110 BPM Preschooler heart rate
75-100 BPM School-ager heart rate
60-90 Adolescent Heart rate
60-100 Adult Heart rate
Ventricle Contraction Systole
Ventricle Relaxtion Diastole
Difference of systolice and diastolice pressure Pulse Pressure
BP cuff too small high reading
BP cuff too big Low reading
Regular Respiration Rate 12 - 20 Breaths/min
Distribution of red blood cells to and from pulmonary capillaries Perfusion
Normal relaxed breathing Eupnea
Normal SPO2 90% ^
When assessing Respirations document; Rate, Rhythm, Depth
Levels of ____ in arterial blood normally regulate ventilation CO2
Lack of breathing Apnea
Respiratory rate <12 Bradypnea
Respiratory rate >20 Tachypnea
Force exerted on walls of artery Blood Pressure
Cardiac Output X peripheral vascular resistance = Blood Pressure
Stroke Volume x Heart Rate = Pulse Pressure
Analgesics ___ BP Lower
How many ml produced in cardiac output 60-70ml
Reduces elasticity Artiereolsclerosis
Thickness of blood Hematocrit
Usual blood volume 5000 ml
Hypertension High Blood Pressure
Hypotension Low Blood pressure
Orthostatic Hypotension Reduction of systolic pressure by 20 mmHg or diastolic of 10 mmHg
Fever symptoms? Increased body temp, dry warm skin, chills, feeling of malaise, tachycardia
