Dialysis TreatmentPrinciples of Osmosis and Diffusion
What is Dialysis?
Complex Medical Procedure
Used to Remove Excess Water and Waste From the Blood
Prolongs Life in Individuals Who Suffer From Kidney Failure
Utilizes the Principles of Osmosis and Diffusion
Has Experienced an Increase in Demand
Bloodstream Components
Solutes
Solvents
Electrolytes, Sugar, Salt
Water
Dialysis Uses What is Known as Dialysate
Dialysis Machine
Contains a Permeable Membrane
Impermeable to Blood and Proteins
Allows the Body to Retain Important Particles
Small Particles Like Waste and Water are Filtered
A Damaged Membrane May Allow Important Particles to Pass
How Dialysis Works
Blood is Transported From the Body to the Machine
Blood Travels Past the Permeable Membrane
Small Particles are Filtered
Dialysate Carries Filtrate to Disposal Container
Cleaned Blood is Transported Back to the Body
Osmosis
Describes How Solvents Move Across Membranes
From Area of Low Particle Concentration to High Concentration
Water Leaves the Bloodstream to Follow Solutes
Can Be Reabsorbed by the Body
Diffusion
Describes How Solutes Move Across Membranes
From Areas of High Concentration to Low Concentration
Particles Travel Out of the Blood and Into Collection Area
Shunting of Filtrate Maintains the Concentration Gradient
Treatment Duration
Typically Lasts Between 3 and 5 Hours
Blood is Circulated Through the Machine Many Times
Without Treatment Waste Would Accumulate
Treatments Must Occur 3 to 5 Times Each Week
Generally Administered by a Dialysis Technician
