Look over principles of safe wheelchair transfers
| Body mechanics, principles of lifting handout
Look over principles of safe wheelchair transfers
| Body mechanics, principles of lifting handout
27
Principles of lifting
technologist should stand with feet apart to increase base of support
patients center of gravity (S-2) should be held close to the clinicians center of gravity (s-2) this posistion is the best advantage for lifting
Keep back stationary, let legs do all the lifting
Do not tist or bend

True
31
In all wheelchair transfer you should make sure the wheelchair's...
wheels are locked
| footrests are removed or folded out of the way so they do not obstruct patient movement
32
How should you execute the wheelchair transfer
let the patient do as much as they can
| execute transfer slowly with grace and control so the patient feels secure
33
How should you position the wheelchair in regards to the table?
45 degree angle to table
34
Instructions for wheelchair patient
1. Scoot your pelvis to the front of the wheelchair
2. put your hands on the arms of the wheelchair
3. lean forward with your nose over your toes and stand up
4. reach for and hold the table with the closest hand to the table
5. pivot so you are standing with your pelvis against the table
6. sit down gently on the table
35
What kind of lift if used for patients who cannot transfer independently but can bear weight on their legs?
standing pivot technique
36
What the steps for a standing pivot technique?
1. Position wheelchair at a 45-degree angle to the table with the patient's stronger side closest to the table
2. move wheelchair footrests out of the way
3. lock wheelchair wheels
4. have the patient push down on the arms of the wheelchair to assisit in rising with patient's nose over toes
5. Bend at the knees, keep your back straight, and grasp the patient's waistband or a transfer belt with both hands
6. Patient's feet and knees must be blocked to provide stability, especially for patient's that have muscle weakness and may not be able to move or feel sensation in lower extremeties
7. Technologist places one foot outside the patients foot while the knee is placed at the medial (inside) surface of the patient's knee
8. as patient rises to standing position rise also by strenthening your kneees
9. When patient is ready both of you pivot toward the table until the patient can feel the table against the back of the thighs
10. ask patient to support him or herself on the table with both hands and to sit down
11. help the patient sit by gradually lowering him or her to the table. make sure lowering comes from technologist's knees

39
What is a two-person lift?
some patient's cannot bear weight on their lower extremities and must be lifted onto table. if patient is lightweight a two-person lift can be used
stronger person should lift the patient's torso while the second person lifts the patient's feet.
Person lifting the torso usually direct's the other person's actions
40
Steps for two-person lift
1. Verbally plan out the procedure
2. position wheelchair parallel to the table
3. lock wheelchair wheels, remove armrests, and swing away or remove footrests
4. ask patient to cross arms over the vhest
stronger person stands behind patient, reaches under the patient's axillae, and grasps patient's crossed forearms
5. second paerson squats in front of the patient and cradles patients thighs in one hadna dn calves in the other
6. On command, patient is lifted to clear the wheelchair and is moved as a unti to the desired place
41

enables a coordinated effort among the people doing the transfer and the patient
allows for troubleshooting before the execution of the transfer

smooth, thin sheets of plastic
canvas or plastic over small rollers
all designed to be used as aids during cart-to-table transfers
48
Steps for a stretcher transfer w/out a moving device
a draw sheet is needed
1. check that sheet is properly positioned for transfer
2. roll up the draw sheet on both sides of the patient
3. person directing transfer should support patient's head and upper body from far side of the table
4. second person should support the patient's legs from the far side of the table
5. third person should support patient's pelvis from the stretcher side- this person makes sure stretcher does not move away from the table during the transfer
6. patient's arms should be crossed over chest to avoid injury or interference with a smooth transfer
7. person at patient's head gives the command and directs the transfer.
