SCUF is a continuous renal replacement therapy (CRRT) generally used to remove fluid from fluid overloaded patients with acute kidney failure. During SCUF blood is continuously removed from the body, passed through an extracorporeal circuit through a hemofilter, and send back to the body. A predetermined percentage of plasma water is removed in ...
Before implementing continuous renal replacement therapy (CRRT), acute renal failure (ARF) in critically ill, multiple organ failure patients was managed by intermittent hemodialysis and the mortality rate was very high. [4] Hemodialysis is effective in clearance and ultrafiltration, but it has deleterious effects on hemodynamic stability. [5]
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal). [6] Dialysis uses highly purified (also known as "ultrapure") water. [7]
Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used. This avoids any need to access wires and makes remodelling fast and simple.
By permitting the automatic racking of the circuit breaker from a remote location, the remote racking systems move service personnel outside the arc flash protection boundary, thus reducing the need for a full-body arc flash hazard suit. A remote switch operator is used to remotely operate various types and styles of circuit breakers and controls.
