Vital Signs Flashcards
Purpose
- to obtain baseline measurement of patients vital signs
- to access patient’s response to treatments
- to monitor patient’s condition after procedure
Temperature
Heat of body measured in degrees and the diff between production of heat and loss of heat
Heat production
Thru food metabolism and activity, increased thyroxin production, and Chem thermogenesis
Heat loss
Thru Radiation- surface to surface by waves Conduction- contact between 2 surfaces Convection-movement by air currents Evaporation-water to stream Elimination-urination, defecation
Types of temp
- core temp: measured thru tympanic and rectal routes
- surface temp: measured thru oral and axillary routes
Oral
Most frequently used, convenient
Rectal
Most accurate, invasive
Axillary
Safer than oral, least accurate
Tympanic
Accessible, less invasive
Pyrexia
Elevated body temp
Hyperpyrexia
Body temp over 41 degrees c
Intermittent fever
Body temp alternates regularly
Remittent fever
Fluctuations of several degrees above normal but never reaches normal
Constant fever
Consistently elevated and fluctuates
Relapsing fever
Returns to normal for 1 day then bad again
Resolution of Pyrexia by crisis
Body temp returns to normal suddenly
Pulse
Wave of blood being pumped into the arterial circulation by the contraction of the left ventricle
Rate
Number of beats per minute
Rhythm
Pattern of beats and interval between each beat
Volume/amplitude
Amount of blood pumped with each heartbeat
Pulmonary ventilation
Breathing, movement in and out of lungs
External respiration
Exchange of O2 and co2 between alveoli and blood
Internal respiration
Exchange of O2 and co2 between blood and tissue cell
Coastal/thoracic breathing
Involves external intercoastal muscles and other accessory muscles
Diaphragmatic/abnormal breathing
Involving the contraction and relaxation of diaphragm
Eupnea
Normal, effortless
Tachypnea
RR> 24 BPM
Braypnea
RR> 10 BPM
Apnea
Absence of breathing
Hyperpnea
Deeper respiration with normal rate
Chyne stokes
Respiration becomes faster/deeper then slow
Blot’s
Faster and deeper with abrupt pauses
Kussmaul’s
Faster and deeper respiration a without pauses between pants
Apneustic
Prolonged grasping with extremely short exhalation
Dysnea
Difficulty in breathing
Orthopnea
Can’t breathe when lying down
Wheezing
Narrowing of airways causing whistling sounds
Stridor
High pitched sounds on inhalation
Rales
Sound caused by air passing thru fluid or mucus in the airways
Rhonchi
Sound caused by air passing thru airways narrowed by fluids
Vital signs
Aka Cardinal signs; includes temp, pulse, respiratory rate, and blood pressure
-reflects physiologic status of a patient
