Which are the four main vital signs? |
temp, heart rate, blood pressure, respiratory rate - pain is now also considered a vital sign |
|
What is the diurnal cycle? |
The cycle of the changes of ones body temp |
|
Which method of measuring temp is the most accurate? |
Tympanic or rectal - rectal not often used due to intrusive nature of testing |
|
Which factors impact ones core temperature? (4) |
- exercise - stress - menstruation -age |
|
What does febrile mean? |
Core body temp higher than 37.5 |
|
At what temp does hyperthermia occur? |
39 degrees |
|
At what temp does hypothermia occur? |
25-35 degrees |
|
What temp range is afebrile? |
35.8 - 37.5 |
|
what are the four ways temp can be measured? |
- axilla (armpit) - tympanic (ear) - rectal -oral |
|
What is bradycardia? |
A heart rate in an adult less than 60 bpm |
|
What is cardiac disrhythmia? |
irregular heart rate |
|
What is sinus arrhythmia? |
When the heart rate varies with the respiratory system. Speed up at inspiration - down on expiration |
|
every time a heart beats how much blood is ejected? |
About 70mls |
|
What is tachycardia? |
heart rate of higher than 100 bpm |
|
What are the different force categories for heart rate? |
0 = absent 1+ = weak/thready 2+ = normal 3+ = bounding |
|
What is a normal respiratory range |
10-20 breaths per minute |
|
What is tachypnoea? |
Fast shallow breathing |
|
What is bradypnoea? |
Abnormally slow breathing |
|
What is apnoea? |
Cessation of breathing |
|
What is hyperventilation? |
Rapid Deep Breathing |
|
What is dyspneoa? |
laboured breathing |
|
What is orthoponea? |
Postion dependent breathing |
|
What is adventitious sound? |
Wheezing |
|
What is blood pressure? |
The force of blood pushing against the side of its container (vessel wall) |
|
What is the systolic pressure? |
the maximum pressure felt on the left ventricular contraction or systole |
|
What is the diastolic blood pressure? |
the elastic recoil or resetting pressure that blood exerts constantly between each contraction. |
|
What is the pulse pressure? |
the difference between systolic and diastolic and reflects the pulse pressure |
|
What is the MAP |
mean arterial pressure - the pressure forcing blood into the tissues averaged over the cardiac cycle. |
|
Which seven factors affect blood pressure? |
1. Age 2. Stress 3. Weight 4. Exercise 5. Emotions 6. Diurnal Rhythm 7. Gender |
|
Which five factors determine bp? |
1. cardiac output 2. Peripheral vascular resistance 3. Volume of circulating blood 4. Viscosity of blood 5. Elasticity of vessel walls |
|
What is the auscultatory gap? |
An auscultatory gap is a period of diminished or absent Korotkoff sounds during the manual measurement of blood pressure. |
|
What is hypertension? |
A bp of 140/90 or higher |
|
What is hypotension? |
A bp of 90/60 or less |
