Inflammation of lung parenchyma as a result of infection.
generated by cardiac output.
2 things that contribute to cardiac output:
1. Stroke volume
2. Heart rate
The amount of blood ejected out of the left ventricle.
is the amount of blood in the ventricle at the end of diastole (resting part of the contraction of the heart).
If there is less preload then the chamber of the heart is not as
full as it needs to be and this will cause a decrease in stroke volume.
If stroke volume is decrease then
cardiac output is decreased.
In heart failure if the chamber is overfull then it can't be
pumped out of the heart and there will be fluid backup or overload.
This is the BP or how hard it is for the heart to push the blood through the arteries.
If the BP is too high then there is too much
resistance and that will cause a decrease in blood flow causing a decrease in perfusion.
If the BP is too low then there is not enough
resistance to maintain adequate blood flow and this will also lead to a decrease in perfusion.
Blood flow into the tissues.
The force of the contractions of the heart creates pressure that pushes the
blood through the capillaries into the interstitial spaces delivering oxygen and nutrients into the cells.
Things that increases oxygen demand are:
Things that decreases oxygen demand are:
The most common cause of CAD is
build up of atherosclerotic plaque in the coronary arteries
Atherosclerotic plaque in the coronary arteries causes
reduced blood supply to the heart muscle.
necrosis of myocardial cells; occurs when blood flow to a portion of the cardiac muscle is blocked.
Cell starving of oxygen
Women have unique risk factors including:
or feeling of abdominalfullness, feeling of chronic fatigue despite adequaterest, and feeling unable to catch their breath.
The nurse should expect a sudden onset of acute chest pain from:
a coronary artery spasm, in which there is an acute reduction in coronary blood flow.
A gradual increase in peripheral edema:
is a sign of heart failure.
Clinical manifestations of a myocardial infarction (MI) include:
tachypnea, anxiety, vomiting, and electrocardiogram (ECG) changes in the Q wave.
is a predictable form of angina, which usually occurs when the work of the heart is increased by physical exertion, exposure to cold, or stress.
Unstable angina puts the patient more at risk for developing:
Fatigue, shortness of breath, physical limitations due to fatigue, and undisturbed sleep are all marks of:
stage II heart failure.
the patient is progressing independently in an exercise routine at home.
has the patient moving from bedrest to providing self-care.
is characterized by increased activity, improvement of psychosocial status, and treatment of anxiety. .
physiological abnormality is a cardiac output that is inadequate to meet the metabolic demands of the body, initially during exercise but, as the syndrome progresses, also at rest.
