Vital Signs N200/200L Spring 2012 11/12/16 Guidelines for Measuring Vital Signs O Establish a baseline O Understand and interpret values O Appropriately delegate O Communicate findings O Ensure equipment is in working order O Accurately document findings 11/12/16 Vital Signs O Cardinal signs O Body Temperature O Pulse O Respirations O Blood pressure O Pulse Oximeter O Pain (considered a vital sign) 11/12/16 Vital Signs How often should you assess vital signs? O Change in client’s health status O Client reports symptoms (baseline changes) O Pre and post procedures O Pre and post medication administration that may affect CV system O Pre and post nursing intervention that may vital signs O Routine according to agency O According to specific orders 11/12/16 Body Temperature O Body temperature = balance between heat produced and heat lost from body Measured in degrees O Temperature range: O 98.6°F to 100.4°F or 36°C to 38°C O Temperature sites: O Oral, rectal, axillary, tympanic membrane, temporal artery, esophageal, pulmonary artery 11/12/16 Body Temperature O Two kinds of body temperature: O Core temperature O Temperature of DEEP tissues of body, such as abdominal cavity O Surface temperature O Temperature of skin, subcutaneous tissue and fat Not as constant as core temperature rises and falls in response to the temperature 11/12/16 Body Temperature Regulation Neural and vascular control Heat production Heat loss Skin temperature regulation Behavioral control Thermoregulation 11/12/16 Body Temperature O Heat Production O Basal Metabolic Rate (BMR) O O O Rate of energy utilization to maintain essential physiological activities such as breathing Rates decrease with age Muscle Activity Thyroxine output (Thyroid Gland) O Increases cellular metabolic rates Chemical thermogenesis 11/12/16 Body Temperature O Heat Production O Epinephrine, Norepinephrine, and sympathic stimulation O O All three increase the rate of metabolism in many body tissues Fever O Increases cellular metabolic rate, thus increasing body temperature (infectious process) 11/12/16 Factors Affecting Body Temperature O Diurnal variations O (circadian rhythms) O Age O Exercise O Hormones O Stress O Environment 11/12/16 Assessment of Ventilation O Easy to assess O Respiratory rate O Ventilatory depth O Ventilatory rhythm O Diffusion and perfusion O Arterial oxygen saturation 11/12/16 Components of Vent/Resp Assessment O Rate O Breaths per minute O Eupnea O Bradypnea O Tachypnea O Depth O Normal O Deep O Shallow O Rhythm O Regular O Irregular O Quality O Effort O Sounds O Effectiveness O Uptake and transport of O2 O Transport and elimination of CO2 11/12/16 Respirations O Recognizing Inadequate Breathing O Labored breathing O Use of accessory muscles O Pale or blue skin O Cool, clammy skin O Irregular respirations O Abnormal lung sounds 11/12/16 Pulse Oximetry O Noninvasive O Estimates arterial blood oxygen saturation (SpO2) O Normal SpO2 85-100%; < 70% life threatening O Detects hypoxemia before clinical signs and symptoms O Sensor, photodetector, pulse oximeter unit 11/12/16 Pulse Oximetry O Factors that affect accuracy include: O Hemoglobin level O Circulation O Activity O Carbon monoxide poisoning 11/12/16 Systolic and Diastolic Blood Pressure O Systolic O Contraction of the ventricles O Diastolic O Ventricles are at rest O Lower pressure present at all times O Measured in mm Hg O Recorded as a fraction, e.g 120/80 O Systolic = 120 and Diastolic = 80 O Pulse Pressure = difference between systolic and diastolic pressures 11/12/16 Diastole Systole 11/12/16 Arterial Blood Pressure and Physiology O Force exerted on walls of an artery O Systolic and diastolic O Cardiac output O Peripheral resistance O Blood volume O Viscosity O Elasticity 11/12/16 Factors Influencing Blood Pressure O Age O Stress O Ethnicity O Gender O Daily Variation O Medications O Activity, weight O Smoking O Assessment of blood pressure and pulse evaluates the general state of PERFUSION and cardiovascular health 11/12/16 Korotkoff’s Sounds 11/12/16 Hypertension and Hypotension Hypertension More common than hypotension Thickening of walls Loss of elasticity Family history Risk factors Hypotension 90 mm Hg Dilation of arteries Loss of blood volume Decrease of blood flow to vital organs Orthostatic/postural 11/12/16 Measurement of Blood Pressure O Equipment O Auscultation O Children O Ultrasonic stethoscope O Palpation O Lower extremity O Electronic blood pressure 11/12/16 Important Concepts O Hypertension O Hypotension O Orthostatic hypotension O Narrow/wide pulse pressures 11/12/16 Delegation of Measurement of Vital Signs O General considerations prior to delegation O Nurse assesses to determine stability of client O Measurement is considered to be routine O Interpretation rests with the nurse O T, P, R & B/P O Routine measurement may be delegated to UAP O UAP reports abnormal temperatures O Nurse interprets abnormal temperature and determines response 11/12/16 Oxygen Saturation Delegation O Application of the pulse oximeter sensor and recording the Sp02 may be delegated to UAP O Nurse interprets oxygen saturation value and determines response 11/12/16 [...]... disposable O Infrared (tympanic) O Temperature-sensitive tape O Glass mercury O Scanning infrared (temporal artery) 11/12/16 Nursing Care for Fever O O O O O Monitor vital signs Assess skin color and temperature Monitor laboratory results for signs of dehydration or infection Remove excess blankets when the client feels warm Provide adequate nutrition and fluid O Measure intake and output O Reduce physical... respirations O Abnormal lung sounds 11/12/16 Pulse Oximetry O Noninvasive O Estimates arterial blood oxygen saturation (SpO2) O Normal SpO2 85-100%; < 70% life threatening O Detects hypoxemia before clinical signs and symptoms O Sensor, photodetector, pulse oximeter unit 11/12/16 Pulse Oximetry O Factors that affect accuracy include: O Hemoglobin level O Circulation O Activity O Carbon monoxide poisoning 11/12/16... More common than hypotension Thickening of walls Loss of elasticity Family history Risk factors Hypotension 90 mm Hg Dilation of arteries Loss of blood volume Decrease of blood flow to vital organs Orthostatic/postural 11/12/16 Measurement of Blood Pressure O Equipment O Auscultation O Children O Ultrasonic stethoscope O Palpation O Lower extremity O Electronic blood pressure 11/12/16
