Normal Vital Sign Ranges
Temp: 96.8-100.4
Pulse: 60-100
Respiratory: 12-20
Blood Pressure: 120/80
O2 sat: 95-100
Pain: 0-10
Assessing for with pulse
Rate
Rhythm
Strength
Symmetry
Cardiac Output
CO= HR x SV
Stroke vol is amount of blood that leaves the left ventricle with one pump
Therefore…
CO is the amount of blood pumped throughout one minute
Brachycardia
HR of less than 60
Tachycardia
HR of more than 100
What inc HR
During exercise
Fever
Emotions
Medication
Fluid loss
Sitting to standing
Low O2
What Dec HR
At rest
Hypothermia
Meds
Lying down
Blood Pressure
Pressure of blood forced on arterial walls
Systolic Pressure
Peak pressure exerted against arterial walls as ventricles contract and eject blood
Diastolic Pressure
Minimum pressure exerted against arterial walls between cardiac contractions when the heart is at rest
What effects BP
Cardiac output
Peripheral vascular resistance
Blood volume
Blood viscosity
Blood flow
Vasoconstrict(inc)
Vasodilation (Dec)
Hypertension
Walls thicken, loss of elasticity
Elevated: 120-129/80
Stage 1 HTN: 130-139/80–89
Stage 2 HTN: 140/90
Basically too much blood is being pumped or vasoconstriction
Hypotension
Systolic pressure is <90
Inadequate pumping of heart, loss of blood vol, vascular dilation
Orthostatic hypotension
When you stand up too fast and blood pressure drops and causes a dizzy spell
3 factors that effect respirations
Ventilations
Diffusion
Perfusion
Ventilation
Movement of gases into/out of lungs
Diffusion
Movement of O2 and CO2 into/out of alveoli and RBCs
Perfusion
Distribution of RBCs to and from pulmonary caps
Assessment of respirations
Rate
Rhythm
Depth
Effort
Bradypnea
Rate is regular, but slow (below 12 per min)
Tachypnea
Rate is regular, but fast (above 20 per minute)
Dyspnea
Labored breathing
Orthopnea
Inability to breath when horizontal
SOB
Shortness of breath
Hypoxemia
Low levels of O2 in blood
Hypoxia
Low levels of blood in tissues
Temperature equation
Temp = heat produced - heat lost
How to measure non-invasively
Oral, tympanic, temporal, axillary
Invasive temperature
Esophageal temp probe
Rectal temp probe
Temp sensing urinary cathader
Hypothermia
Core temp colder/below normal
