Basic Observations Flashcards
Why take basic observations?
To gather information,
Determine Baseline,
Monitor Change
Blood Pressure of a radial pulse and carotid Pulse?
Radial shows systolic of 90.
Carotid shows Systolic of 60-70
Femoral of 80.
Pulse Rates. Adults, 5-11, 2-5, 1-2, <1
Adults - 60-80 5-11 - 80-120 2-5 - 95 -140 1-2 - 100-150 <1 - 110 - 160
Define Tachycardia and Bradycardia
Tachy above 100
Brady 60
Factors Affecting The Heart Rate
Autonomic Nervous System Circulating Chemicals Position of the body Exercise Emotional states Gender Age Temperature Baroceptor reflex (Blood Pressure Control)
Define Systolic Pressure
Define Diastolic Pressure
Systolic - Peak press in the arteries caused by contraction of left ventricle
Diastolic - Minimum pressure of the blood against the walls when ventricle is not contracting
Normal blood pressure
120/80 mmhg
Hypotension - Readings
Systolic below 90
Diastolic below 60
Hypertension - Readings
Systolic above 140
diastolic above 90
Hypothermia
core temp above 35c
Pyrexia
significant rise in temperature
fever
caused by pyrexia
Hyperprexia -
rating
how is it different from hyperthermia
Core temperature above 40c
Hyperthermia is overheating from external sources, such as the sun
Temperature Ranges Normal Low grade Pyrexia High grade Pyrexia Hyperpyrexia
Normal - 36-37.5c
Low Grade Pyrexia - 37.5-38
High Grade Pyrexia - 38-40
Hyperpyrexia 40+C
Oxygen Saturation
Normal - 94-98%
COPD 88-92%
Definition of Peak expiratory flow rate
Peak expiratory flow rate (PEFR or Peak Flow) is a measurement of the highest rate at which air can be expelled from the lungs through an open mouth
What does PEF detect?
Moderate and severe respiratory disease
Measure the degree of airway obstruction
What influences PEF?
Height
Age
Gender
Contraindications of PEF
Severe breathlessness
Persistent cough
A reducing PEFR on numerous attempts
