oscillation

 [os″ĭ-la´shun]
a backward and forward motion, like that of a pendulum; also vibration, fluctuation, or variation.
high frequency oscillation a type of high frequency ventilation characterized by the use of active expiration.

os·cil·la·tion

(os'i-lā'shŭn),
1. A to-and-fro movement.
2. A stage in the vascular changes in inflammation in which the accumulation of leukocytes in the small vessels arrests the passage of blood and there is simply a to-and-fro movement at each cardiac contraction.
[L. oscillatio, fr. oscillo, to swing]
