Vital Signs/Cardinal Signs Flashcards
What are the 5 vital signs?
Temperature Pulse Respirations Blood Pressure Pain
balance between heat produced by the body and heat loss from the body
Body Temperature
Types of body temperature
Surface and core temperature
Temperature of the deep tissues of the body such as abdominal and pelvic cavity.
Core temperature
Temperature of skin, SQ tissue and fat. Rises and falls in response to the environment.
Surface temperature
4 processes involved in heat loss
- Radiation - transfer of heat from surface to surface of one object to surface of another w/o contact
- Conduction - transfer of heat from one surface to another through direct contact
- Convection - dispersion of heat by air currents
- Evaporation - vaporization of moisture from the respiratory tract, mucosa of the mouth and skin
Body temperature is above the usual range
Pyrexia/Hyperthermia/Fever
Very high fever, 41°C (105.8°F) and above
Hyperpyrexia
Core body temperature is below the lower limit of normal
Hypothermia
What are the 5 types of fever?
Intermittent - alternates at regular intervals
Remittent - wide range of temp fluctuations more than 2°C for over 24 hrs
Relapsing - short febrile periods
Constant - fluctuates minimally but always remains above normal.
Fever spike (Staircase) - temperature rises to fever level rapidly following a normal temperature then returns to normal within a few hours
What are the four ways of assessing body temperature?
Oral
Rectal
Axillary
Tympanic Membrane
Considered to be the most convenient and most accessible way of assessing body temperature
Oral
Considered to be a very accurate way of assessing body temperature
Rectal
Safest and non-invasive way of assessing body temperature
Axillary
Frequent site for estimating core body temperature
Tympanic Membrane
When will you start Tepid Sponge Bath (TSB)?
If there is 1°C to 2°C increase in body temperature
Wave of blood created by contraction of the left ventricle of the heart
Pulse
What are the 8 pulse sites?
- Temporal
- Carotid
- Radial
- Apical
- Brachial
- Femoral
- Popliteal
- Posterior tibia and Dorsal Pedal
excessively fast heart rate (over 100 beats/min)
Tachycardia
