|
Patent Ductus Arteries (PDA) |
When the pulmonary artery & aorta have a hole that pumps deoxygenated blood to the body |
|
|
What artery supplies blood to the cardiac muscle |
The right coronary artery |
|
|
At what week does the fetus potentially is capable of gas exchange? |
22 weeks |
|
|
Forman Ovale |
Opening in the right and left atrium |
|
|
Tetralogy of Fallot & 4 abnormalities |
Opening in the right and left ventricles Pulmonary stenosis Ventricular Septum Defect R. Ventricular Hypertrophy Overriding or dextropositioning of the Aorta |
|
|
Angina Pectoris |
Central chest pain, spreading to the shoulders, neck, and arms (Not enough blood to the heart) |
|
|
Effects of antidiuretic hormone on blood pressure (ADH) |
⬆️ reabsorption of water ⬆️ blood pressure and volume ⬆️ cardiac output |
|
|
Myocardial Infraction (MI) |
Heart attack Not enough oxygen in the tissue to the heart |
|
|
Purpose of the Placenta |
Blood flow Exchange of nutrients and wastes Oxygen delivery & CO2 removal |
|
|
Know the respiratory function of a fetus |
It doesn't have one |
|
|
Sinoatrial Node (SA Node) |
Pacemaker of the heart |
|
|
Umbilical Cord |
2 Arteries : carries deoxygenated blood from fetus to placenta 1 Vein: carries oxygenated blood from the placenta to the fetus Whartons Jelly: prevents cord from kinking & stopping blood flow |
|
|
Necrosis |
Dead tissue Lack of blood supply |
|
|
Ischemia |
Inadequate blood flow to parts of the body. esp. the heart |
|
|
System Vascular Resistance (SVR) |
The force of the left ventricle to pump blood to the aorta and out to the body |
|
|
Frank Staring Mechanism |
The greater the stretch the greater the recoil |
|
|
Myocardium |
Middle layer of the heart |
|
|
Endocardium |
The inner layer of the heart |
|
|
Epicardium |
Outer layer of the heart |
|
|
Arterial Natriuretic Peptides effects the on blood pressure? |
⬇️ blood pressure Inhibits aldosterone and promotes sodium loss (releases fluids) |
|
|
What happens to cardiac output , when the heart rate goes over 170 beats per minute |
⬇️ the cardiac output It's not pumping the blood out fast enough from the ventricles |
|
|
Fetal hemoglobin effect the dissociation curve to the LEFT |
⬆️ affinity O2 ⬆️ PH ⬇️ PCO2 ⬇️ Temperature ⬇️ HBF |
|
|
Hypertension |
MAP > 110 Systolic > 135-140 Diastolic > 90 |
|
|
Equation for Pulse and Pressure |
Systolic ➖ Diastolic |
|
|
Fetal hemoglobin effect the dissociation curve to the RIGHT |
⬇️ Affinity O2 ⬇️ PH ⬆️ PCO2 ⬆️ temperature ⬆️ DPG |
|
|
Equation for MAP (Mean Arterial Pressure) |
Systolic ➕ Diastolic ✖️2 __________________________ 3 |
|
|
Equation for SVR (Systemic Vascular Resistance) |
MAP ➖ RAP or (CVP) ✖️ 80 ____________________ Cardiac Output |
|
|
Pathway to blood to the heart |
Supr & inferior vena cava R. Atrium Tricuspid R. Ventricle Pulmonary artery Lung capillaries Pulmonary vein L. Atrium Bicuspid (mitral valve) L. Ventricle Aorta |
