Vital Signs
- Measurements of the body's most basic functions
- Traditional vital signs: body temperature, pulse, respiration, blood pressure
- Additional vital signs: pain, oxygen saturation
Monitoring Vital Signs
- Methodical, scientific approach
- Evaluate regarding the client's present/prior health status, usual readings, and accepted standards
- Increased frequency if client's health status warrants it
Times to Assess Vital Signs
- Admission to a healthcare setting to establish baseline data
- When a client experiences a change in health condition or reports symptoms (e.g., chest pain, feeling faint).
- Before/After surgery or an invasive procedure
- Before/After medication with potential effects on respiratory/cardiovascular systems (e.g., digitalis administration)
- Before/After any nursing intervention affecting vital signs (e.g., transferring a confined client.)
Body Temperature
- Balance between heat production & loss
- Measured in degrees
- Core temperature: deep body tissues (abdominal/pelvic cavity)
- Surface temperature: skin, subcutaneous tissue, fat (influenced by the environment).
- Body is in heat balance when heat produced equals heat lost
Factors Affecting Heat Production
- Basal metabolic rate (BMR): decreases with age, higher in younger people.
- Muscle activity: shivering increases BMR
- Thyroxine output: a hormone that increases cellular metabolism
- Epinephrine & norepinephrine: released during stress, increases cellular metabolism, and thus increases body temperature.
- Fever: elevates cellular metabolic rate, raising body temperature.
Mechanisms of Heat Loss
- Radiation: transfer of heat from one object to another without contact (infrared rays)
- Conduction: transfer of heat from one molecule to another of lower temperature; direct contact required.
- Convection: heat loss via air currents.
- Evaporation: water loss from respiratory tract and skin; called insensible heat loss.
Body Temperature Regulation
- System with three main parts:
- Sensors in the periphery and core
- Integrator in the hypothalamus
- Effector system adjusting heat production and loss.
Physiological Processes Raising Body Temperature in Response to Cold exposure:
- Shivering (increased heat production)
- Reduced sweating (decreased heat loss)
- Vasoconstriction (reduced heat loss).
Hypothalamic Integrator
- Controls core temperature.
- Sends signals to reduce temperature by decreasing heat production and increasing heat loss when heat is detected
- Sends signals to increase heat production and decrease heat loss when cold is detected.
Effector System
- Initiates responses like vasoconstriction, shivering, and epinephrine release (increased cellular metabolism, heat production) when cold stimuli detected.
- Initiates sweating and vasodilation when warmth stimuli detected.
- The client can also make voluntary adjustments such as wearing more clothes or using a fan.
Factors Affecting Body Temperature
- Age (infants are most susceptible to environmental temperature changes.)
- Circadian rhythms (lowest body temperature during the night.)
- Exercise (increases body temperature.)
- Hormones (progesterone in women around ovulation.)
- Stress (sympathetic nervous system stimulation boosts metabolic activity & heat production.)
- Environmental factors (extremes of heat/cold.)
Alterations (Temp.)
- Pyrexia (fever): body temperature above normal range
- Hyperpyrexia (iperpyrexia): body temperature around 41°C
- Febrile/afebrile: describing a person with/without fever
- Different types of pyrexia (e.g. intermittent, remittent, relapsing, constant, spike).
- Heat exhaustion: excessive heat/dehydration; moderately elevated temp. - Heat stroke: A dangerously high temp.; warm flushed skin and can lead to delirium/loss of consciousness.
Hypothermia
- Low core body temperature
- Three mechanisms: excessive heat loss, inadequate heat production, impaired hypothalamic thermoregulation
- Clinical signs: decreased body temperature, pulse, and respirations; shivering (initially); pale, cool skin; frostbite; hypotension; decreased urinary output; lack of muscle coordination; drowsiness/ coma.
- Two types: induced and accidental
Assessing Body Temperature
- Oral (wait 30 minutes)
- Rectal (accurate, but not appropriate in certain circumstances)
- Axillary (lower readings than rectal)
- Tympanic (core temperature)
- Forehead (suitable for infants/children)
Types of Thermometers
- Mercury-in-glass (outdated)
- Electronic
- Chemical disposable
- Temperature-sensitive tape
- Infrared
- Temporal artery
Temperature Scales
- Celsius/Centigrade (using degrees Celsius)
- Fahrenheit (using degrees Fahrenheit). Conversion formulas provided.
Pulse
- Wave of blood created by left ventricle contraction
- Reflects stroke volume/amount of blood entering arteries with each contraction.
- Affected by arterial compliance (ability to contract/expand). With age, this decreases, requiring higher pressure to pump.
- Cardiac output = Stroke volume X Heart rate (example calculation)
Factors Affecting Pulse
- Age (decreases with age)
- Sex (males generally have slower resting pulse rates.)
- Exercise
- Fever (increased heart rate)
- Medications (some affect heart rate)
- Hypovolemia/dehydration
- Stress
- Body Position
- Pathology
Pulse Sites
- Temporal
- Carotid
- Apical (heart)
- Brachial
- Radial
- Femoral
- Popliteal
- Posterior tibial
- Dorsalis pedis
Assessing Pulses
- Palpating/listening
- Consider medications, recent activity, baseline data, and positional changes affecting rate.
Respirations
- Act of breathing (inhalation, inspiration, exhalation, expiration, ventilation)
- Two types: costal/thoracic breathing and diaphragmatic/abdominal breathing.
Mechanics and Regulation of Breathing
- Inhalation: diaphragm contracts (flattens), ribs move upward/outward, sternum moves outward, enlarging thorax and lungs
- Exhalation: diaphragm relaxes, ribs move downward/inward, sternum moves inward, decreasing thorax size and compressing lungs
- Automatic and effortless process
Factors Controlling Respirations
- Respiratory centers in the medulla oblongata and the pons
- Chemoreceptors (centrally in medulla/peripherally in carotid/aortic bodies) respond to changes in oxygen (O2), carbon dioxide (CO2), and hydrogen (H+) levels in the arterial blood.
Assessing Respirations
- Rate (normal, abnormally slow, abnormally fast, absence of breathing)
- Depth (shallow, deep, normal)
- Rhythm (regular, irregular)
- Quality (effort required, abnormal sounds)
- Relationship to cardiovascular system
Factors Affecting Respirations
- Exercise/Stress/Temperature/environmental oxygen concentration
- Medications (e.g., morphine)
- Increased intracranial pressure.
Breathing Patterns
- Tachypnea, Bradypnea, Apnea
- Hyperventilation/Hypoventilation
- Biot breathing, Cheyne-Stokes breathing
Breath Sounds
- Descriptions and causes of different sounds (crackles, gurgles, friction rub, wheeze).
- Location of audible sounds.
Blood Pressure
- Measure of pressure exerted by blood as it flows through the arteries.
- Systolic pressure: peak pressure during ventricular contraction
- Diastolic pressure: lowest pressure when ventricles relax
- Pulse pressure: difference between systolic and diastolic pressure
Determinants of Blood Pressure
- Pumping action of heart
- Peripheral vascular resistance (arterial stiffness)
- Blood volume
- Blood viscosity
Factors Affecting Blood Pressure
- Age, Exercise, Stress, Race/Ethnicity Sex. Medications, Obesity, Diurnal variation. Medical conditions. Temperature
Blood Pressure Scales
- Normal blood pressure readings/MAP
- Elevated Blood Pressure Readings
- Hypertension / Hypotension
Assessing Blood Pressure
- Manual blood pressure measurement methods using a cuff, sphygmomanometer, and stethoscope
- Indirect measurement methods: auscultatory, palpatory, direct (invasive)
Assessing Blood Pressure
