Group Project Flashcards
List all the different cardiac factors
(7)
Systolic pressure
Diastolic pressure
Mean systemic arterial pressure
Cardiac output
Heart rate
Stroke volume
Total peripheral resistance
What is systolic pressure
The amount of pressure experienced by the arteries while the heart is beating
What is diastolic pressure?
The amount of pressure in the arteries while the heart is resting in between heart beats
What is Mean systemic arterial pressure?
The average arterial pressure throughout one cardiac cycle, systole, and diastole
What is cardiac output?
Cardiac output is how many litres of blood your heart pumps in one minute
Stroke volume x heart rate
What is stroke volume?
The volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.
What is total peripheral resistance?
The amount of resistance to blood flow present in the vascular system of the body
List the pulmonary factors
(4)
Minute ventilation
Respiratory rate
Tidal volume
Vital capacity
List the metabolic factors
(3)
Oxygen consumption (VO2)
Respiratory Exchange Ratio (RER)
Carbon dioxide production (VCO2)
List the thermal factors
(4)
Metabolic rate
Core body temperature
Pallor
Sweat
What is minute ventilation?
the amount of air a person breaths in a minute.
Tidal volume x respiratory rate
What is tidal volume?
The amount of air that moves in or out of the lungs with each respiratory cycle
What is vital capacity?
The greatest volume of air that can be expelled from the lungs after taking the deepest possible breath
What is the respiratory exchange ratio?
The ratio between the amount of carbon dioxide (CO 2) produced in metabolism and oxygen (O 2) used
What is metabolic rate
The rate of energy expenditure per unit time
What type of testing is this?
Cardiopulmonary exercise testing
What type of exercise is this?
Incremental exercise
Why are CPET exams carried out?
They can be used to assess patient’s with pulmonary or cardiac diseases
How effective are CPETs at identify heart abnormalities?
70% of heart abnormalities can be exposed
Who was our subject?
A healthy 19 year old with no comorbidities
How was the exercise carried out?
Using a bicycle ergometer
How was core temperature measured?
Using a tympanic thermometer (in ear canal)
How was respiratory rate of the patient measured?
By watching the rise and fall of the patient’s chest
How was systolic and diastolic blood pressure recorded?
Measured using the auscultatory method at rest
Measured using a sphygmomanometer during exercise
