the normal stimulus to breathe for most people is an increase of carbon dioxide in the blood
Hypercapnia
a decrease of oxygen in the blood, also increases respirations but is less effective than hyercapnia
Hypoxemia
S2 is heard loudest at the
Base
S2 is the ______ heart sound
Second
S2 is the ____ of systole
End
S1 is the _____ of systole
Start
S1 is heard loudest at the
Apex
Mitral valves and tricuspid valves are ____ sounds
S1
Aortic and pulmonic valves are _____ sounds
S2
Heard when the ventricles are resistant to filling during the early rapid filling phase (protodiasole)
S3
Increases in velocity of blood flow - flow murmur e.g., in exercise, thyrotoxicosis
Decreases in viscosity of blood (e.g., anemia)
Structural defects in the valves (narrowed valve, incompetent valve) or unusual openings in the chambers (dilated chamber, septal defect)
Causes of heart murmurs
All heart sounds are described by four characteristics:
Frequency (pitch)
Intensity (loudness)
Duration
Timing; systole or diastole
may also be a pulmonary, musco-sekeltal, or gastro intestinal organ; it is important differentiate
Chest pain
Occurs when heart’s vascular supply cannot keep up with metabolic demand
Angina
A squeezing “clinched fist” sign is characteristic of _________, but the symptoms listed below may be equivalents in the absence of chest pain
Angina
Related to cardiac failure
Heard after S2
Is heard when ventricles are resistant to filling during the early rapid filling phase (protodiastole)
Kentucky sound
S3
Related to hypertension
Heard before s1
Occurs at the end of diastole, at presystole, when the ventricle is resistant to filling
Tennessee sound
