Positioning

Front 1

Describe beach chair position

Back 1

legs should be elevated as close as possible to the level of the heart and slightly flexed to prevent sciatic nerve traction
45-60 degrees, flexion at the hips and slightly flexed

Front 2

beach chair arm position and why

Back 2

arms should be elevated to avoid traction of hte shoulder muscles and brachial plexus

Front 3

what is beach chair position used for?

Back 3

neurosurgical exposure of cspine, breast, sholder, arm, crani, thyroid

Front 4

physiological considerations with beach chair position?
CV, neuro, resp, peripheral nerves

Back 4

CV- hypotension r/t venous pooling, decrease CO 10%, decrease preload

Neuro- pnumo
resp- improves ventilation and access to airway, less facial swelling.
peripheral nerves- brachial plexus compression at humoral joint, sciatic compression, ulnar nerve.

Front 5

indications for lateral position

Back 5

thorax, kidneys, rectal, spine/crani, hips, shoulder

Front 6

complications with lateral decubitus

Back 6

neck angulation (occlusion of veterbral or arotid arteries which can increase ICP)
dependent lung is underventilated
nondependent lung is over inflated
v/q mismatch
decrease SVR and BP
eye pressure
