Temperature
|
balance maintained by the body between heat loss and gain
|
|
Body loses heat thru five processes:
|
convection-fan or wind across body
conduction-sleeping on ground radiation-heat leaving a wood stove evaporation-sweating elimination-carried with body waste |
|
Things that increase temperature
|
muscle activity
digestion ovulation pregnancy emotion |
|
Things that decrease temperature
|
lack of activity
fasting sweating exposure to cold age/size |
|
Temperature Normal and Average
|
There is no normal
Avg temp for an adult is 98.6/37.0 Normal range: 97-99 <97hypothermia >99-104low grade fever |
|
Types of fever
|
Intermittant, remittant, continuous
|
|
Intermittant fever
|
Fluxuates from a normal or below temperature to an increased one, going back and forth.
|
|
Remittant fever
|
Fluxuating fever that never returns all the way to normal.
|
|
Continuous fever
|
The increased temperature is maintained and does not fluxuate
|
|
Febrile
|
Fever
|
|
Pyrexia
|
Fever
|
|
Phases of Fever
|
Onset: fever begins. (pale, shivering).
Fastigium: fever becomes active. (heat,flushed,malaise,sweaty). Resolution: body returns to normal temp. (Lysis/gradual,Crisis/sudden w/sweating) |
|
Fastigium
|
The second phase of fever when it become active. (heat,flushed,malaise,sweaty)
|
|
Diaphoresis
|
excessive sweating
|
|
Types of thermometers
|
glass,disposable,digital,tympanic,
temporal artery. Mercury discontinued in 98 |
|
R, A, Tym, TA
|
Rectal- 1 degree higher than oral
Axillary- 1 degree lower than oral Tympanic- Equal to oral Temporal Artery- 1 degree higher than oral. |
|
Pulse sites
*3 most common |
temporal,*carotid, apical, *brachial,*radial,femoral,popliteal,
dorsalis pedis, posterior tibia |
|
Influencing factors: Pulse
|
age,gender,size,physical activity,emotional stress,disease,meds,pain
|
|
3 characteristics of pulse
|
Rate,Strength,Regularity
|
|
Pulse rate Definition
Pulse adult normal and normal range |
# of beats per minute.
Adult normal is 72bpm Adult range: 60-100 |
|
Tachycardia
|
A pulse rate that is > than 100bpm
|
|
Bradycardia
|
A pulse rate that is < 50bpm
|
|
Pulse strength
|
refers to force. Amount of blood forced into an artery by the heart. (strong,bounding, weak, thready, irregular)
|
|
Pulse regularity
|
Rhythm or eveness of the beats.
|
|
3 types of regularity
|
Regular
Irregular:Time between beats or strength of beats changes. Intermittant-beat is skipped, strength doesnt vary. |
|
Apical pulse found
|
5th intercostal space, midclavicular on left side of pt.
|
|
Normal respiration rate
|
1:4 ratio
|
|
Factors that influence respiration rate
|
age, size, physical activity, emotions, medications, disease, smoking, fever, body position
|
|
Characteristics of respiration
|
rate: breaths per minute
Normal adult range: 12-20 Rhythm: regular pattern of breathing. Depth: the amount of air being breathed in and out; deep or shallow. Audibility: How the breathing sounds. |
|
5 Breath sounds
|
Rales: crackling
ronchi: rattling wheeze: windy stridor: heard on inspiration stretorous: snoring |
|
Apnea
|
absence of breathing.
longer than 10 sec at sleep req. CPAP |
|
Tachypnea
|
rapid respiration rate, rises with body temp about 4 breaths per minute with every degree above normal.
|
|
Bradypnea
|
slower than normal respirations. tumors, alcohol, opiates
|
|
Orthopnea
|
difficult or painful breathing lying down, relieved when sitting up.
|
|
Hyperpnea
|
increase in rate and depth of breath. Excercise.
|
|
Dyspnea
|
painful or difficult breathing
|
|
Hypoventilation
|
decrease in rate and depth of respirations
|
|
Hyperventilation
|
increase in depth, rate, and duration of breathing. Can cause dizziness, fainting, and tingling.
|
|
O2 levels measure what
|
percent of oxygen present in blood stream
|
|
pulse oximeter
|
used to gauge 02 %
|
|
Normal O2 level
|
94% or above.
90% or lower needs supplementation 88% or lower is abnormal. |
|
4 main factors that affect blood pressure
|
Blood Volume,
Peripheral Resistance, Vessel Elasticity, Condition of heart muscle |
|
Other factors that affect blood pressure
|
activity, stress, gender, meds, disease, daily flux
|
|
Blood pressure cuff called
|
sphygmomanometer
|
|
types of sphygmomanometers
|
mercury
aneroid digital |
|
Korotkoff Phases/Sounds
|
l: First sound heard. Recorded as systolic reading
ll: swishing sound, blood passing lll: rhythmic tapping, cuff deflating lV: muffling; fading of tapping, cuff deflating V: Sound disappears; recorded as diastolic reading. |
|
Normal Blood Pressure Adult
|
110/70 to 140/90
|
|
Abnormal Blood Pressure
|
Hypertention is > 140/90
Hypotention is < 90/60 |
|
Systole
|
Heart in action
|
|
Diastole
|
Heart at rest
|
|
Patient positioning for BP
|
arm is supported at heart level
uncrossed legs pt rested and relaxed bladder should cover 2/3 of pt arm |
|
Common Errors taking BP
|
wrong cuff size
arm not at heart level deflating cuff too fast (2-4mmHg per beat) re-inflating cuff within 1-2 minutes improper cuff placement |
|
Steps to taking BP
|
Center bladder of cuff over brachial artery 2-3 inches above the elbow.
Position stethoscope over brachial artery. Avoid using thumb. Inflate cuff smooth and quick to 180-200. Deflate cuff smooth and steady rate. Listen for Korotkoff sounds. Note when they appear. Continue deflating cuff. Note when all sounds disappear. Continue deflating 10mm past last sound. Completely deflate and remove cuff. Comfirm pt comfort, record results. |
|

|
|
Always do what to scale
|
Zero out scale when done!!!
