Chapter 13 Flashcards
What is biomechanics?
Branch of science that applies the laws of physics to living creatures - used for safe lifting
What type of injury is the leading cause for disability in the US?
Back injury
Fundamentals to safe patient handling involve:
Base of support
Center of gravity
Mobility
Stability muscles
What is the base of support?
Foundation on which a body rests.
How to enlarge base of support?
Stand with feet apart
What is the center of gravity?
Hypothetical point at which all mass appears to be centered. Sacral level 2
How should you move objects?
Hold close to your center of gravity
Center of gravity must always be over:
Base of support
What are mobility muscles?
Found in limbs
Biceps, hamstrings
What are stability muscles?
Found in torso
Latissimus dorsi
Rectus abdominis
What are mobility muscles used for?
Lifting
What are stability muscles used for?
Postural support
How should wheelchair be positioned for a stand-by assist transfer?
45 degrees to the table, determine patient’s abilities
How should wheelchair and patient be positioned for assisted standing pivot transfer?
45 degrees to the table, strong side closest to the table; use transfer belt
How should you lift a patient when doing a two person lift?
Stronger person lifts torso; other person lifts legs and feet
How should cart be aligned with the table?
Car alongside the table, patient strongest side closest to the table
How many people should do a cart transfer?
3
How should poeple do the cart transfer?
One at the head, one at the chest/pelvic girdle, on at the legs
Person supporting pelvic girdle stays on side of cart
Person at head gives commands
Always roll patient towards:
You
Commonly attached medical equipment
Oxygen tubing, IV lines, urine bags, CVLs
What causes orthostatic hypotension
A decrease in vasomotor tone in blood vessels results in a decrease in oxygen to the brain
What cart transfer device has the greatest potential for back strain in the radiographer
Draw sheet
