blood pressure Flashcards
is one of the most important vital signs because it aids in diagnosis and treatment, especially for cardiovascular health.
blood pressure
is the amount of force exerted on the arterial walls while the heart is pumping blood— specifically, when the ventricles contract
blood pressure
what are the 2 types of blood pressure
systolic and diastolic
is the highest pressure that occurs as the left ventricle of the heart is contracting.
systolic blood pressure
is the lowest pressure level that occurs when the heart is relaxed and the ventricle is at rest and refilling with blood
diastolic blood pressure
While blood pressure is read in millimeters (mm) of mercury (Hg), or “mmHg”.
normal bp in adult
120/80
A narrowed pulse pressure may be an indicator for congestive heart failure (CHF), stroke, or shock.
pulse pressure
normal systolic (mmHg)
90-120
normal diastolic (mmHg)
60-80

decrease arterial blood volume
Direct (invasive) blood pressure monitoring is recommended in sick and compromised patients, those who are at risk of developing major blood loss during surgery or for whom abnormal blood gases are anticipated
What are the 2 Indirect (Non-invasive) bp
- Auscultatory
- Palpatory
is the instrument used for measuring the pressure that the blood exerts against the walls of the artery
sphygmomanometer
What are components of a sphygmomanometer
manometer, inflatable rubber bladder, cuff, and bulb.
What are the 3 Types of sphygmomanometers:
• Mercury,
• Aneroid, and
• Electronic
