Osteopathic Approach to the Cardiopulmonary Patient Flashcards

1
Q

What biomechanical spine condition can hamper cardiopulmonary function? How is it measured?

A

Scoliosis

Measured by Cobb angle to determine mild (5-15), moderate (20-40), or severe (>50) — formed by intersection of line parallel to superior end plate of the most cephalad vertebra in a particular curve, with the line parallel to the inferior end plate of most caudad vertebra of the curve

Q

The cardiac plexus can be divided into superficial and deep cardiac plexi. The deep cardiac plexus can further be divided into a right and left half. What structures are associated with right vs. left half of the deep cardiac plexus?

A

Right half = right coronary plexus, left coronary plexus, SA node

Left half = AV node

[cholinergic and adrenergic fibers passing through the cardiac plexus are most strongly concentrated in the SA and AV nodes, and to a significantly lesser extent in the myocardium]

A 62-year-old woman comes to the emergency department after two weeks of shortness of breath. She gets out of breath easily when walking short distances and has felt more fatigued recently. She has a dry nighttime cough, which she attributes to a “cold.” She denies chest pain or pressure, palpitations, lightheadedness, or syncope. She was diagnosed with hypertension four years ago but does not take any medications. She has never smoked and rarely drinks alcohol. She has no family history of heart disease. Blood pressure is 165/92 mm Hg, and pulse is 99/min and regular. If you suspect this patient has CHF, which of the following would you expect to hear on cardiac auscultation? a.
