Vital Signs
• Body temperature, pulse, respirations, and Blood Pressure
• Monitor functions of the body• Should be a thoughtful, scientific
assessment
![Page 3: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/3.jpg)

When to Assess Vital Signs
• On admission• Change in client’s health status• Client reports symptoms such as chest
pain, feeling hot, or faint• Pre and post surgery/invasive procedure• Pre and post medication administration
that could affect CV system• Pre and post nursing intervention that
could affect vital signs

Body Temperature
• Reflects the balance between the heat produced and the heat lost from the body
• Measured by heat units called degrees

Alterations in Body Temperature
• Pyrexia, Hyperthermia, Fever- body temperature above the usual range
• Febrile- a client who has a fever
• Afebrile- a client who does not have fever
• Hypothermia- core body temperature below the lower limit of normal
![Page 7: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/7.jpg)

Pulse
• Is a wave of blood created by contraction of the left ventricle of the heart
• Represents the amount of blood that enters the arteries with each ventricular contraction
• Peripheral pulse- a pulse located away from the heart Ex. Foot or wrist
• Apical pulse- is the central pulse that is located at the apex of the heart

Temperature: Lifespan Considerations
Infants UnstableNewborns must be kept warm to prevent hypothermia
Children Tympanic or temporal artery sites preferred
Elders Tends to be lower than that of middle-aged adults
![Page 12: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/12.jpg)

Pulse: LifespanConsiderations
Infants Newborns may have heart murmurs that are not pathological
Children The apex of the heart is normally located in the fourth intercostal space in young children; fifth intercostal space in children 7 years old and older
Elders Often have decreased peripheral circulation
![Page 13: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/13.jpg)

Respirations:Lifespan Considerations
Infants Some newborns display “periodic breathing”
Children Diaphragmatic breathers
Elders Anatomic and physiologic changes cause respiratory system to be less efficient
![Page 14: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/14.jpg)

Blood Pressure:Lifespan Considerations
Infants Arm and thigh pressures are equivalent under 1 year of age
Children Thigh pressure is 10 mm Hg higher than arm
Elders Client’s medication may affect how pressure is taken

Alteratered Breathing Patterns
• Rate– Tachypnea – quick, shallow breaths– Bradypnea- abnormally shallow breathing– Apnea- absence or cessation of breathing
• Volume-Hyperventilation- overexpansion of the lungs characterized by rapid and deep breaths-Hypoventilation- underexpansion of the lungs characterized by shallow respirations
![Page 33: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/33.jpg)
Copyright 2008 by Pearson Education, Inc.
Alteratered Breathing Patterns
• Rhythm– Cheyne- Stroke breathing- rhythmic waxing
and waning of respirations, from very deep to very shallow breathing and temporary apnea
• Ease or Effort– Dyspnea- difficult and labored breathing
during which the individual has a persistent, unsatisfied need for air and feels distressed
– Orthopnea- ability to breathe only in upright sitting or standing positions
![Page 34: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/34.jpg)

Alteratered Breath Sounds
• Stridor – a shrill, harsh sound heard during inspiration with laryngeal obstruction
• Wheeze- continuous, high pitched musical squeak or whistling sound occuring on expiration
![Page 35: Vital signs](https://reader033.fdocuments.in/reader033/viewer/2022052310/554b4aa2b4c905ff268b534c/html5/thumbnails/35.jpg)

Systolic and Diastolic Blood Pressure
• Systolic – Contraction of the
ventricles
• Diastolic – Ventricles are at rest– Lower pressure
present at all times
• Pulse Pressure = difference between systolic and diastolic pressures
• Measured in mm Hg
• Recorded as a fraction, e.g. 120/80
• Systolic = 120 and Diastolic = 80
