Vital Signs Flashcards
(26 cards)
Normal body temperature
96-99.6 F
What are the vital signs
Temperature, pulse, respiration & blood pressure
Three phases in the course of a typical fever
Chills, hot stage, sweating
When does febrile convulsions occur?
When temperature rapidly rises from normal to fever level
What is Hot stage?
When temp reaches the set point fever
Hyperparexia?
What does it possibly indicates?
Greater 105 -
Possibly damage to hypothalamus
3 heat-hydration conditions,
signs,
symptoms.
Heat cramps - loss of Na; hypertonicity legs and abdomen.
Heat exhaustion - cold clammy, sweaty skin; heart & CNS become blood deprived; dizzines, weakness, headache.
Heat stroke - high temp w/ high humidity; hot dry skin; dyspnea, arrhythmia, dilated pupils, seizures, coma & death.
Hypothermia
Body temp 95 or less
Resting heart rate
60-90 per min
Tachycardia
- physiologic
- pathologic
More than 100 per min
- normal response to exertion
- oxygen deficit (anemia, hemorrhage)
3 common irregularities in heart rhythm:
- Sinus arrhythmia - children; HR inc w/ inspiration, dec w/ expiration.
- Premature Ventricular Contraction (PVC’s) - occasional skipped beats; causes by early depolarizations
- Atrial fibrillation - disorganized electrical activity. Rapid irregular ventricular response. Emergency
What is pulse amplitude?
Normal scale?
Force
0-4. 2 is normal (light pressure does not stops the pulse)
Heart pulse Contour
Smooth, domed shape waveform produces in healthy heart and arteries
What does bilateral pulses are compared for?
Amplitude and contour
What does strong radial and weak or absent femoral pulses suggests?
Coarctation of the aorta
What does capillary refill time cheks?
Arterial compromise (compressed, constricted or obstructed)
What is a Bruit?
A typically low pitch, pulses and relatively quite sound. It implies arterial compromise
Respiration rate in normal adult
12-20 resp per min
What is an auscultatory gap?
a transient period of silence of the Korotkoff sounds
What are Korotkoff sounds?
Audible noises created by turbulent blood flow through a partially open lumen of the brachial artery. They change 4 times as the artery slowly opens.
What is pulse pressure?
Difference between systolic and diastolic pressures.
Systolic pressure range
100-140 mm Hg
Diastolic pressure range
60-90 mm Hg
Normal Pulse pressure
40 mm of Hg
