Exam #3 Flashcards
Systole
the phase of the heartbeat when the heart muscle CONTRACTS and pumps blood from the chambers into the arteries.
Diastole
the phase of the heartbeat when the heart muscle RELAXES and allows the chambers to fill with blood.
Cardiac Output
the volume of blood pumped by the hear per minute
Preload
is the end diastolic volume that stretches the right or left ventricle of the heart to its greatest dimensions
Afterload
is the pressure in the wall of the left ventricle during ejection of blood
Contractility
is the strength of the heart’s contraction during systole
Which is the last vital sign to change?
Blood Pressure `
Cardiac Indicators:
poor feeding tachypnea/tachycardia failure to thrive/poor weight gain/activity intolerance developmental delays \+ prenatal history \+ family history for cardiac disease
Cardiac Disorders: Postoperative care
Monitor the Respiratory system
Prevent pooling of lung secretions
Post cardiac surgery syndrome
Post perfusion syndrome
Altered hemodynamics: Acyanotic
No cyanosis= normal color
Problem pumping blood from the Left ventricle to the body
Increase blood flow problems and obstruction of blood flow from the ventricles
Acyanotic: INCREASED blood flow disorders:
Atrial Septal defects
Ventricular Septal defects
Patent Ductus Arteriosis
Atrioventricular canal
Acyanotic: OBSTRUCTION of blood flow from ventricle disorders:
Coarctation of Aorta
Aortic Stenosis
Pulmonic Stenosis
Altered Hemodynamics: Cyanosis
Decreased oxygen causing blue or grey discoloration
issues with right ventricle and lungs, decreased O2 in lungs
Cyanotic: DECREASED pulmonary blood flow disorders:
Tetralogy of Fallot
tricuspid atresia
Cyanotic: MIXED blood flow disorders:
Transposition of the Great arteries
Total anomatous pulmonary venous return
Truncus arteriosus
Hypoplastic left heart syndrome
