Pulse
A rhythmical throbbing for the arteries as blood is propelled through them.
Most Common site for taking a pulse in an adult
Radial Artery
Most Common site for taking a pulse in an infant
Apical
Tachycardia
Heart rate over 100bmp
Bradycardia
A heart rate under 60bmp
Normal Pulse
60-100 bpm
How to count heart rate for normal pulse
Count pulse for 30sec and multiply by two
How to count heart rate for irregular pulse
Count pulse for a full minute
Respiration
Complete ventilation cycle, inhalation and exhalation
Normal adult respiration for class exam
16-20 breaths per minute
Normal adult respiration rate for NHA exam
12-20 breaths per minute
Good practice for taking pts respiration
Pretend to still be taking pulse when measuring respiration rate so pts breathing doesn’t change
Hyperventilation
Over-breathing that leads to a decrease in CO2 in the body
Tachypnea
Rapid shallow breaths
Pulse oximetry
Test to measure the oxygen level (oxygen saturation) or the blood
What pulse ox value is critical
at or below 94%
Hypoxemia
Poor oxygenation of the blood
Fever treatment infants less than 3-months
Rectal temp in 100.4*
Fever treatment infants 3-6 months
101*+ or any fever over a day
Fever treatment 6 months- 1 year
103*+ or any fever lasting longer than a day
Fever treatment in infant 1 year or older
104*+ or any fever lasting over a day
Blood Pressure
The force aqueous blood exerts on the arterial walls
Where to find pulse for blood pressure?
Brachial artery
Rate to release cuff for blood pressure
2-3mmHG/sec
Record systolic reading when
You hear the first tapping sound
Record diastolic reading when
Last sound you here
Normal systolic number
120
Normal diastolic number
80
Hypertension
High blood pressure (HTN)
Hypotension
Low Blood Pressure
Height measurement unit
cm (will depend on place, could be other unit)
Weight measurement unit
Reported in kg
BMI
Body Mass Index
BMI underweight range
<18.5
BMI healthy range
18.5-24.99
BMI Overweight Range
25-29.99
BMI Obese Range
30+
Calculating BMI in kg
Weight (kg)/ Height (m²)
Calculating BMI in lbs
(Weight (lbs) *700/ height (in)/ height (in)
In regards to the Chest girth to abdominal circumference ratio, risk of heart disease increases when…
The waist measurement exceeds the chest measurement
