Guidelines for Measuring Vital Signs • Establish a baseline for future assessments. • Be able to understand and interpret values. • Appropriately delegate measurement. • Communicate findings. • Ensure equipment is in working order. • Accurately document findings.
Circulatory Needs • Circulation is monitored through assessment of Vital Signs along with other collected data. • The patient’s physiological status is reflected by their vital signs.
VitalSigns:TPR and BP • Signs of Vitality and Life • Deviations from normal ranges can indicate in health status. • TPR & BP = VS • T-temperature • P-pulse • R-respirations • BP- blood pressure • VS-vital signs
CNS Regulates VS • Hypothalamus: Controls temperature • Anterior Hypothalamus -Dissipation of heat • Posterior Hypothalamus-conservation of heat • Medulla: • Vasomotor center controls BP through vasoconstriction or vasodilation • Cardiac center controls pulse • Respiratory center controls respirations(rate and depth)
Relationship Between VS • R = 1/4 P • R 20 = P 80 • P = diastolic BP • P 80 = 120/80 • T increases = an increase in P R and BP
Factors Influencing VS • Age • Gender • Race • Diet • Weight • Heredity • Medications • Activity
More Factors Influencing VS • Pain • Hormones • Stress • Emotions • Circadian Rhythms
Guidelines for Assessing VS • Systematic • Normal Range • Baseline • Recheck • Client Norm • Treatments • Monitor prn
Heat Production • By product of metabolism • B.M.R.- Basal Metabolic Rate • Muscle activity • Exposure to increased temperature • Hormones: Thyroxine, Epinephrine
Heat Loss (Transfer) • Conduction - direct transfer of heat by contact
Heat Loss-Convection • Heat dissemination via motion. A fan blows warm air across a warm body.
Heat Loss-Radiation • Heat given off by rays from the body. Heat loss from an uncovered head. • Main form of heat loss.
Heat Loss-Evaporation • Conversion of a liquid to a vapor. Perspiration vaporizes from the skin. • Diaphoresis
????What are some other ways heat is lost from body??? • URINE • FECES • RESPIRATIONS
Fever Patterns • Intermittent • Remittent • Constant • Relapsing
?? Fever Terminology ??Which term can be used to describe a fever that: • Is constantly elevated with little fluctuation • CONSTANT • Fluctuates but does not come down to normal • REMITTANT • Returns to normal for a day or two, but then goes up again • RELAPSING • Alternates between normal and fever • INTERMITTANT
S/S of Fever • Loss of appetite Delirium • Headache Seizures • Dehydration Thirst • Flushed face ????? • Rapid pulse • Decreased urinary output(OLIGURIA)
Temperature ranges • Oral- 96.8 – 100.4 F • 98.6 = average norm • Axillary- approximately 1 degree lower • Rectal- approximately 1 degree higher
Assessing Temperature • Glass • Electronic • Tympanic • Tape/Patch • Disposable (ie: Clinidot)
Oral Temperature • Most common site • Place against sublingual artery • Contraindicated in oral surgery/infection • Wait 15 min. if pt. ate/drank or smoked • Electronic- blue probe
Axillary Temperature • Preferred for children under 6 yrs. routinely used on infants. • Place in center of axilla against artery off the subclavian.
Rectal Temperature • Last resort for assessing temperature • Place against inferior rectal artery • Contraindicated rectal surgery/cardiac pt. • Lubricate thermometers
(Continued) Rectal Temperature • Electronic thermometers: • Red Probe only • Insert : ½ - 1 inch adult ¼ - 1/2 inch child • Left position is best
??? Nursing Diagnoses ??? • HYPERTHERMIA • HYPOTHERMIA • RISK FOR IMBALANCED BODY TEMPERATURE
Nursing Interventions Temperature • Check VS frequently • Assess skin • Note change in LOC • Seizure precautions ? • Monitor I & O • REDUCE COVERINGS • Encourage fluids • Tepid baths • Administer antipyretics • Promote comfort & REST • Hypothermia blanket
Nursing Interventions Temperature • Check VS frequently • Assess skin • Note change in LOC • Seizure precautions ? • Monitor I & O • REDUCE COVERINGS
Hypothermia • Mild (93.2 – 96.8 F) • Moderate (86.0-93.2 F) • Severe ( below 86.0 F)
Evaluations-Temperature • Is patient afebrile? • Are interventions working? i.e. cool compresses, tepid bath, antipyretics? • S/S of infection present?
Nurse’s Notes 5/31/02 4:15pm Reports headache, feeling “on fire”, face flushed, skin warm, T-104.6 A P-100 R- 20 BP- 150/80. Dr. Arrid notified. Tylenol 650mg po administered as per telephone order. Fluids encouraged, tepid bath given. S.Niggemeier RN----------------------------- 4:45pm T-102.2 A P- 88 R-18 BP 130/78 taking fluids, feels “better than before”.

Pulse-Physiology • SA node- creates electrical impulses causing contraction of atria. • A wave of blood is pumped into the arteries. • Throbbing sensation is felt - Pulse • Pulse rate should = the heart rate • Pulse rate is the number of pulsations felt in a minute. • Pulse usually = diastolic pressure
Pulse Rates • Newborn 120-150 • Infant 80-140 • Child 75-110 • Adult 60-100 • Pulse rates ????? as age increases
Cardiac Output CO=SV x HR • Cardiac output (CO) is the amount of blood pumped/min by the heart and = approximately 5000ml or 5L/min • Stroke Volume (SV) is the amount of blood ejectedfrom the L ventricle with each contraction. • Heart rate (HR) is the number of times the heart contracts. • Inversely related- when SV goes up the HR goes down.
?? CARDIAC OUTPUT ??CV (5000) = SV(70) X HR • In the above equation, what would the client’s heart rate be? • APPROXIMATELY 71 BPM • If a client had a weak heart (ie:CHF) that was only able to eject a SV of 50, what would happen to the client’s HR? • IT WOULD RAISE TO 100 BPM • If a client had a well-conditioned heart muscle (ie: athlete) that was able to eject a SV of 100, what would their HR be? • IT WOULD DECREASE TO 50 BPM
Pulse Sites • Temporal • Carotid • Apical • Brachial • Radial • Femoral • Popliteal • Dorsalis Pedis • Posterior Tibia
Pulse assessment • Rate -number of beats /min • Rhythm- pattern of the rate. Regular or Irregular. Count irregular rhythm for 1 min. • Quality- strength of the pulse 0-4+
Pulse - Quality Scale • 4+ bounding very strong, does not disappear with moderate pressure • 3+ normal, easily felt, • 2+ weak, light pressure causes it to disappear • 1+ thready, not easily felt, disappears with slight pressure • 0- no pulse
??? NURSING DIAGNOSES • Decreased cardiac output • Ineffective tissue perfusion • Activity intolerance
Nursing Interventions-Pulse • Monitor for symmetry • Note pulse deficit • Promote circulation – i.e. massage
Evaluations • Is pulse with normal range? • All pulses present • Equally Bilateral? • Are interventions to promote circulation working? i.e. massage
Terminology • Bradycardia- HR below 60/min • Tachycardia- HR above 100/min • Sinus Arrhythmia- HR increases on inspiration and decreases on exhalation common in children and young adults
Terminology • Dysrhythmia- abnormal rhythm • Palpitation-aware of your HR without feeling for it…usually rapid • Pulse deficit- difference between apical and radial pulses Apical-100 Radial-80 then the Pulse deficit is 20
Pulse Documentation • 23/11/2010 1:20am : palpitations. P-96 reg 3+. • No pulse deficit.------------------- S.Niggemeier RN
Respirations Physiology Process whereby CO2 and O2 are exchanged in the tissues. • Oxygenation of the body • CO2 is the stimulus for breathing • Inspiration - breathing inDiaphragm contracts – pulls down • Expiration- breathing outDiaphragm relaxes – moves up • Normal Tidal Volume = 500 ml
Respiration Rates • Newborn 40-60/min • Child 20-30 • School age 18-26 • Adult 16-20 • Respirations decrease as age increases
Assessing Respiratory Status • Oxygenation status • Neurological state • Musculoskeletal status
Oxygenation status • Note S/S of hypoxia (oxygen deprivation • Cyanosis - bluish tinge caused by decrease in O2 in RBC. • Cyanosis is assessed by checking the mucous membranes of the conjunctiva (lower eyelids), under the tongue and inside the mouth..should be pink not pale or bluish
??Other signs of dyspnea?? • ANXIOUS LOOK • FLARED NOSTRILS • USE OF ACCESSORY MUSCLES • INTERCOSTAL RETRACTIONS
Neurological state • Hypoxia results in neurological changes • alert • becomes anxious • then irritable • progresses to drowsiness • eventually a coma
