Cardiovascular Measurements Flashcards
Define Heart Rate
The number of times the heart beats in a minute
How do you calculate maximum heart rate?
220-age
What does BPM stand for?
Beats per minute
What does MHR stand for?
Maximum heart rate
Define Stroke Volume
The amount of blood ejected from the heart in one beat
Define Cardiac Output
The amount of blood ejected from the heart per minute
What is the formula for Cardiac Output?
Q = HR x SV
What is Systolic Blood Pressure?
The blood pressure in the arteries during the contraction of the heart (first number)
What is Diastolic Blood Pressure?
The blood pressure in the arteries when the heart rests between beats (second number)
What is high blood pressure?
Blood pressure above 120/80mmHg
What is low blood pressure?
Blood pressure below 90/60mmHg
Where could you find your pulse?
Neck (Carotid pulse), Wrist (Radial pulse) and Thigh (Femoral pulse)
What is the pulse in the wrist called?
Radial pulse
What is the pulse in the neck called?
Carotid pulse
What is the pulse in your thigh called?
Femoral pulse
What are the units of Blood Pressure?
mmHg
Identify 3 factors affecting blood pressure
Age
Stress
Diet
Activity levels
Explain how age affects blood pressure
Blood pressure increases with age
Explain how stress affects blood pressure
Causes an increase in HR and narrowing of arteries
Explain how diet affects blood pressure
Eating foods high in fat, salt and sugar can increase blood pressure.
Fruits, vegetables and low-fat dairy food can help reduce blood pressure.
Explain how diet activity levels affects blood pressure
Exercise can increase BP in the short-term.
Regular exercise can keep BP in the ideal range.
People that don’t exercise can develop high BP
