The word “amplifier” suggests to most persons an electronic component used in the control or switching of a flow of electrons. Fluid amplification is analogous; however, rather than a flow of electrons, a stream of fluid, either a liquid or a gas, is controlled or switched. This fluid is forced to flow through channels of certain geometric configuration cut in a block of solid material. The fluid amplifier controls and switches the fluid stream without electronics and with no moving parts. This…

The construction and operation of fluidic and pneumatic devices in current use, as well as the principles of their use in medical devices are described.
A paediatric ventilator with a fluidic control system.
TLDR
A paediatric ventilator has been designed basically as a fluidic-logic controlled T-piece occluder, isolated from the control and warning systems for ease of sterilization.

TLDR
Technology appears to have outstripped the clinician's ability to harness it most effectively in the past few years, and microprocessors are likely to feature prominently in the next generation of designs.

TLDR
The resistance of the systemic and pulmonary arterial beds to each type of perfusion was investigated in dogs and the optimum form and amplitude of the pulse wave is important in the development of prosthetic indwelling mechanical hearts.
