26 Questions
According to the equation MABP = CO x TPR, what is the role of MABP in the circulatory system?
It drives the flow of blood throughout the system
What is the formula for calculating cardiac output (CO)?
CO = Heart rate (HR) x stroke volume (SV)
How does a decrease in stroke volume (SV), heart rate (HR) or total peripheral resistance (TPR) affect Mean Arterial Blood Pressure (MABP)?
MABP decreases
What does MABP stand for in the given equation?
What does MABP stand for in the given equation?
What is the formula for calculating mean arterial blood pressure?
MABP = cardiac output (CO) x total peripheral resistance (TPR) or MABP = HR x SV x TPR
Where are the pressure receptors (baroreceptors) located in the body
The wall of the arch of the aorta and carotid sinus
What type of information do the pressure receptors (baroreceptors) send back to the central nervous system (CNS)?
Mean arterial blood pressure (MABP)
What happens to the input from the baroreceptors when MABP decreases?
The input from the baroreceptors decreases
How does the activation of the sympathetic nervous system affect MABP?
It increases MABP by speeding up the heart rate and constricting blood vessel
What are the overall effects of the baroreceptor reflex on mean arterial blood pressure (MABP)?
Increasing heart rate and stroke volume, and constricting blood vessels
What hormones affect BP?
Adrenaline, Antidiuretic hormone (ADH, vasopressin), Atrial natriuretic peptide, Renin-Angiotensin-Aldosterone System
What is the range for normotensive blood pressure?
90-135 mmHg systolic and 60-85 mmHg diastolic
What blood pressure readings indicate hypertension?
135 mmHg systolic and >85 mmHg diastolic
How would you define hypotension?
<90 mmHg systolic and <60 mmHg diastolic
If a blood pressure measurement shows 120 mmHg systolic and 70 mmHg diastolic, how would you classify it?
Normotensive
Which component of blood pressure is measured when the heart is at rest?
Diastolic pressure
When determining hypertension, what would be the systolic blood pressure threshold?
135 mmHg
High blood pressure (hypertension) can lead to damage in which of the following organs over time?
Heart, blood vessels, and kidneys
Which term describes a condition where blood pressure is abnormally low and may result in inadequate blood perfusion to tissues?
Hypotension
Chronic high blood pressure can cause damage to blood vessels, leading to an increased risk of:
Stroke and heart disease
Low blood pressure can result in inadequate perfusion of tissues, leading to:
Oxygen deprivation
What is the primary characteristic of primary hypertension?
Elevated blood pressure with no clear cause
Secondary hypertension is characterized by:
Hypertension with a clear underlying cause
What blood pressure readings would categorize a person as having Stage 1 hypertension?
Clinic blood pressure of 140/90 mmHg
What blood pressure readings would classify an individual with Stage 2 hypertension?
Clinic blood pressure of 160/100 mmHg
What blood pressure values indicate Stage 3 or Severe hypertension?
Clinic blood pressure of 180/120 mmHg
