LECTURE: VITAL SIGNS Flashcards
What are the 4 main vital signs
BP
Pulse
Respiration rate
pulse ox
What are some of the other diagnostic signs?
SKIN TEMPERATURE AND CONDITION • PUPILLARY REACTION • CAPILLARY REFILL • LOC • ABILITY TO MOVE (PMSC) • REACTION TO PAIN (PMSC)
When should vital signs be taken initially
when should vital signs be taken after the secondary ?
Initially: if medical condition
Secondary: if trauma
What is blood pressure and what is it necessary for>
BP is the pressure of circulating blood against artery walls
necessary for proper circulation and perfusion
What are the parts of a sphygomomanometer?
cuff bladder tubing valve bulb
What are the parts of a stethescope?
HEADSET
Earpieces
ear tube
tubing
CHEST PIECE
stem
bell
diaphrahm
Where do the earpeices have to be facing?
FORWARD / away from you
What are the korotkoff sounds
phse 1: sharp thud phase 2: blowing/swishing sound 3) thumping 4) Softer sound that dissapears 5) silence
Explain Hypotension and the possible explanations for it
Decreased BP Below90/60mmofHg
Loss of blood or tissue fluid Loss of arterial constriction Cardiac problem Adissons disease (serious adrenal gland disorder) Hypothyroidism
Explain hypertension and possible explanations for it
Increased BP
Arteriosclerosis or atherosclerosis
From head injuries
How does the body compensate for low BP
Heart rate increases
Arteries constrict
less Blood flow to extremities, greater Blood flow to organs
Treat for shock
What are the normal values for BP
Adult: 90 - 140 mm Hg (Systolic) 120
60 - 90 mm Hg (Diastolic) 80
Critically low systolic BP…
Male adult/Adolescent: < 90 mm Hg F
emale adult/Adolescent: < 80 mm Hg
Children: < 70 mm Hg = Critical Hypotension
What are the normal carotid pulse values
- Adults: 60 - 100 beats per minute (bpm)
- Children 60 – 90 bpm (10 – 15yrs)
- Children: 80 - 100 bpm (5 – 10 yrs)
- Children: 80 - 120 bpm (1 – 8 yrs) (CRC)
Define tachycardia and bradycardia
and define the normal and irregular characters of pulse
At rest
tachy: HR above 100
brady: HR below 60
Normal character: bounding strong
Irregular: weak or thready, premature or late beat
What are the normal respiration values
adult: 12-20
child 15-30
infant 30-40
What does stridor mean ?
Stridor = high-pitched sound
What is sputum a sign of? what is pink/white froth a sign of?
Sputum = Advanced respiratory infection
Pink/white froth = chest injury or congestive heart
failure
What is pulse oximetry and when should you give oxygen?
measurement of oxygen saturation of functional hemoglobin of the blood using an pulse oximeter.
When pulse ox is lower than 92%
Where can you see color change in deeply pigmented skin?
- fingernail beds
- mucous membrane of mouth
- lips
- underarm (axilla)
- palm
What can the different skin temperatures indicate?
Hot: Fever, sunburn, hyperthermia
Normal: Warm and dry, Normal core temp 37 oC / 98.6 oF
Cool: Post exci sweating, early shock, heat exhaustion
Cold: Profound shock, frostbite, hypothermia
How long should you hold the rectal thermometer for accurate reading>
2 minutes
What is the purpose of capilary refil? and what is the time it should take?
Reflects perfusion, Circulation assessment
No longer than 2 sec.
When is delayed cap refil normal>
In elderly and when you are cold
What does pupil diameter reflect?
Status of the brain
PERFUSION, OXYGINATION, CONDITION
What does PEARRLA stand for?
PUPILS EQUAL ROUND REACTIVE TO LIGHT ACCOMODATION
What are you checking in an external eye exam?
Extraocular Muscle Function
- Check eye movement through the 6 cardinal directions of gaze.
- Watch for parallel movement
- Nystagmus (involuntary rapid rhythmic movement)
What is considered a normal vs abormal eye reaction
Normal: When a light is shone in one eye, both eyes (pupils) should constrict
Abnomral: do not constrict, A sign of depressed brain function
What are some examples of depressed brain function>
- Injury to brain or brain stem
- Trauma or stroke
- Brain tumour
- Decreased oxygen/perfusion
- Drugs or toxins
WHat are some abnomral signs to look for when checking pupils?
- Fixed, no reaction
- Dilate with light, constrict when removed
- Slow reaction
- Unequal sizes
- Unequal in size with light influence
