Midterm Flashcards
symptoms of chronic bronchitis
Persistent cough Extreme mucus production Shortness of breath, especially with exercise Wheezing Chest tightness
define stable angina
goes away with rest and medication
define unstable angina
pain @ rest or activity (serious warning sign for heart attack)
HR max=
220-age
what is the Mediastinum
Space between the lungs which contains the heart, the aorta, and vena cava
5th cranial nerve responsible for regulating…
Heart rate
Force of each contraction
Cardiac output
what is the sinuatrial node?
group of cells positioned on the wall of the right atrium
what are the 4 most common vital signs?
HR, blood pressure, respiratory rate, and temperature
factors affecting heart rate
Age Gender Environmental Temperature Infection Physical Activity Emotional Status Medications Cardiopulmonary Disease
reference heart rate range
60 bpm (less is bradycardia) and 100 bpm (greater is tachycardia)
pulse points
carotid femoral popliteal radial brachial Dorsalis pedis Tibialis posterior
normal blood pressure ranges
Systolic between 90 and 135mmHg
Diastolic between 50 and 90mmHg
what are direuretics
“water pills” because they work in the kidney and flush excess water and sodium from the body
what are beta blockers used for?
reduce nerve impulses to the heart and blood vessels. This makes the heart beat slower and with less force. Blood pressure drops and the heart works less hard.
oxygen saturation should never be below….
95%
some cardiac evaluation tools
History
Heart rate, pulse and blood pressure
Auscultation
Laboratory tests i.e. Chest Xrays EKG, cholesterol, echocardiogram
Cardiac Stress Testing: Maximal, Sub Maximal
Fitness Testing
what is coronary artery disease?
Occlusion of a major coronary artery leads to an inadequate oxygenation of an area of myocardium and cell death (MI)
valve disease: incompetence
as a result of poorly functioning valves
valve disease: stenosis
narrowing caused by the valve’s inability to open fully
valve disease can either effect….
Mitral or Aortic valves
The most common signs of congestive heart failure are…
swollen legs or ankles or difficulty breathing.
when is the cardiac stress test tested…
during excercise or load
which types of patients are tested with the cardiac stress test?
patients with known coronary artery disease
what is heart rate reserve?
difference between a person’s resting heart rate and maximum heart rate
what is the calculation of heart rate reserve? HRR
HRR = HRmax − HRrest
what are some ways of Grading Exercise Intensity
Borg Perceived Exertion Scale Talk Test Training Heart Rate Zone Metabolic Equivalent Self-monitoring of signs and symptoms
what is the borg perceived exertion scale?
Perceived exertion is how hard you feel like your body is working
