in the review of relevant hx what personal habits should you ask about?
in the review of relevant hx what personal & family hx should you ask about?
Other aspects to inquire about in the review of relevant hx include?
Syncope: Fainting; transient loss of consciousness.
Diaphoresis: Profuse sweating.
Dyspnea: Interference with ADL
Orthopnea: # of pillows
Numbness or pain in the extremities
identify 7 possible causes of chest pain
identify the 4 chambers of the heart
identify the 4 valves in the heart
Superior and Inferior vena cava -->
Right atrium --> Tricuspid valve --> Right ventricle --> Pulmonic valve Pulmonary arteries --> Lungs --> Pulmonary veins --> Left atrium --> Mitral valve --> Left ventricle --> Aortic valve --> Aorta --> Head and Body
during systole what happens to the ventricles and the atria?
Ventricles contract and atria relax
during systole what happens to the pressure in the ventricles?
pressure in ventricles rises
what happens to blood during systole
Right ventricle to lungs
Left ventricle to aorta
during diastole what happens to the ventricles and the atria?
Atria contract and ventricles relax
explain the actions of the valves in the heart during systole
Mitral and tricuspid valves are forced closed to prevent backflow into the atria
This closure produces the first heart sound: S1: "lubb"
When the pressure in the ventricles is > than that in the aorta and pulmonary arteries the aortic and pulmonic valves open
As ventricular pressure falls below atrial pressure during diastole what happens to the valves?
Mitral and tricuspid valves open to allow the blood collected in the atria to refill the relaxed ventricles
what happens during systole when the ventricles are almost empty?
Pressure in ventricles becomes < than that in the aorta and pulmonary arteries
Aortic and pulmonic valves close producing the second heart sound: S2: "dubb"
describe blood flow during diastole
Blood flows in a relatively passive manner
Right atria to right ventricle
Left atria to left ventricle
This passive filling sometimes produces a third heart sound: S3
what happens in the last phase of diastole?
Then the atria contract to eject the remaining blood
This can sometimes be heard as a fourth heart sound:S4
