CONTENTS
 Consciousness
 Body temperature
 Respiration
 Blood pressure
 Pulse
1. CONSCIOUSNESS
Human ability to be aware of own thoughts,
emotions, surroundings → adequate responses
GLASGOW COMA SCALE (GCS)
Patient’s response to:
- verbal stimulation
- painful stimulation
- movement
Scale 3 – 15
CONSCIOUSNESS
Changes in consciousness
QUALITATIVE QUANTITATIVE
anxiety
depression
delirium
somnolent
sopor
coma (shallow/deep)
2. BODY TEMPERATURE
Balance between heat produced and heat lost by the body
Heat regulating centre – hypothalamus
Heat production caused by increasing cell metabolism
Heat losses (cool off process):
- perspiration
- respiration
- radiation
Types of thermometers:
- mercury-in-glass
- electronic
- chemical
BODY TEMPERATURE
BODY TEMPERATURE SYMPTOMS
Hypothermia
↓ 36 °C
Skin paleness
Tiredness
Normal
36 – 36,9 °C
Lowest 5 – 6am
Highest 4 – 6pm
Pyrexia / slight fever
37,0 – 37,9 °C
Perspiration
Skin redness
Headache
Fever
 38 °C
Presence of infection → body defence
General weakness
Tachycardia / hyperpnea
Skin paleness/redness
Shivers
Perspiration
BODY TEMPERATURE
ROUTES FOR MEASURING THE BODY TEMPERATURE
- ORAL
best site for measuring in the clinical settings
triangle shaped thermometer
axillo – oral difference 0,3 °C
- AXILLARY
more likely to be affected by the environmental temperature,
used in children/adults
- RECTAL
fast thermometer, used in infants/confused patients/receiving O2 th.
axillo – rectal difference 0,5 °C
- VAGINAL
used in gynecology
3. RESPIRATION
NORMAL RESPIRATIONS
 Effortless
 Regular
 Smooth
AVERAGE RESPIRATIONS
 Infant to 2 years 24–34/min
 To puberty 20-26/min
 Adults 12-18/min
RESPIRATORY RATE
 Normal 12 – 20 / min
 Bradypnea ↓ 10 / min
 Tachypnea  25 / min
 Apnea
RESPIRATORY RHYTHM
 Normal
 Dyspnea (exertion/rest)
 Cheynes-Stokes respiration
(irregular deep/slow/shallow )
 Kussmaul’s breathing (deep)
4. BLOOD PRESSURE (BP)
The pressure of blood in the arterial wall
Factors affecting BP:
- blood volume
- strength of contraction
- elasticity of artery wall
Assessment:
- Normal 120-140/60-80 mmHg
- Hypertension  150/90 mmHg
- Hypotension ↓100 mmHg
Measurements stated in terms of millimetres of mercury (mmHg)
BLOOD PRESSURE (BP)
BP reading:
- systolic pressure (ventricle contraction)
- diastolic pressure (ventricle at rest)
BP readings record: BP 120/80
Equipment:
- sphygmomanometer
- stethoscope
BLOOD PRESSURE (BP)
Places for measuring:
- upper arm (brachial artery)
- calf / thigh (popliteal artery)
Measuring techniques:
- auscultation
(sphygmomanometer+stethoscope)
- palpation
(sphygmomanometer)
- invasive methods (CVP)
5. PULSE
Expansion of an artery with each hart beat
Measuring techniques / places of assessing:
- PALPATION
a. carotis
a. brachialis, radialis
a. femoralis, poplitea etc.
- AUSCULTATION
stethoscope
PULSE
PULSE RATE
 Normal 60 – 90 / min
 Bradycardia ↓ 50 / min
 Tachycardia  100 / min
 Asystolia
PULSE RHYTHM
 Regular
 Irregular – arrythmia
PULSE QUALITY
 Strong (fever)
 Weak (shock/heart failure)
REPETITION
1. What do you evaluate in Glasgow Coma Scale?
2. What is the normal body temperature?
3. Name 3 symptoms of fever.
4. What is the most commonly used route for measuring the
body temperature in infant?
5. Could you define the term for the high respiratory rate?
6. What is the limit for hypertension?
7. Name 2 methods of BP measurement?
8. Name 2 arteries where the pulse is most commonly felt?
9. Could you specify the normal pulse rate?
10. What is the point at which the beat stops during the BP
measurement called?
THANK YOU !
