What does vitamin D do and what sources can it be found in?

Vitamin D helps to regulate the amount of calcium and phosphate in the body, which makes your bones strong and healthy. It can be found in sunlight, egg yolk, oily fish (salmon, sardines, herring, and mackerel), red meat, liver, and fortified foods.

What is the difference between defibrillation and synchronized cardioversion?

Defibrillation is an automatic shock. It is used when there are no consistent heart beats to synch to or you do not have time to wait for it to synch to shock (V. fib or pulseless V. tach). If used when synchronization is possible, the shock may be delivered at an improper time in the rhythm cycle and cause the patient to go into cardiac arrest. Synchronized cardioversion waits to shock when it senses the correct time in the rhythm cycle. It waits until it can synchronize with the heartbeat. It can be used to convert a patient back to normal sinus rhythm from dysrhythmias with which the patient has a pulse (SVT, stable V. tach, A. fib/flutter).
