  1. Chapter 15 Body Mechanics Health Tech 1

  2. Objectives • Define the key terms in this chapter • Explain the purpose and rules of body mechanics • Explain how ergonomics can prevent workplace accidents • Identify the causes, signs, and symptoms of back injuries • Identify comfort and safety measures for lifting, turning, and moving persons in bed • Explain how to safely perform transfers • Explain why body alignment and position changes are important • Identify the comfort and safety measures for positioning a person • Position persons in the basic bed positions and in a chair • Perform the procedures described in this chapter

  3. BODY MECHANICS • Body mechanics means using the body in an efficient and careful way to reduce the risk of injury. • Body alignment (posture) is the way the head, trunk, arms, and legs are aligned with one another. • All activities require good body mechanics. • Good alignment is necessary when standing, sitting, or lying down.

  4. principles of body mechanics • base of support is needed for balance. • Stand with your feet apart for a wider base of support and more balance. • strongest and largest muscles are in the shoulders, upper arms, hips,and thighs. • Use these muscles to lift and move heavy objects. • Using small muscles to lift and move heavy objects causes fatigue and injury. • Back injuries are a major risk. • Bend your knees and squat to lift a heavy object. • Hold items close to your body and your base of support.

  5. APPLICATION #1 • View each manikin and identify what is wrong with the body position of the manikin. Record your observations on a piece of paper. After all groups have finished with observations we will review the answers.

  6. ERGONOMICS • Ergonomics is the science of designing the job to fit the worker. • The goal is to prevent serious and disabling work-related musculoskeletal disorders or(MSDs).

  7. ERGONOMICS -MSDs • MSDs are injuries and disorders of the muscles, tendons, ligaments, joints, and cartilage 1. The nervous system is also involved. 2. The arms and back are often affected. • can develop slowly or occur from one event. • MSDs are serious workplace health hazards.

  8. ERGONOMICS -MSDs • Signs and symptoms include: • Pain when trying to assume a normal posture • Decreased mobility • Pain when standing or rising from a seated position

  9. ERGONOMICS -MSDs • factors leading to back disorders: • Reaching while lifting • Poor posture when sitting or standing • Staying in one position too long • Poor body mechanics when lifting, pushing, pulling, or carrying objects • Poor physical condition • Repeated lifting of awkward items, equipment, or persons

  10. ERGONOMICS -MSDs • Twisting while lifting • Bending while lifting • Maintaining a bent posture • Heavy lifting • Fatigue • Poor footing, such as on slippery floors • Lifting with forceful movement

  11. POSITIONING THE PERSON WHAT’S WRONG WITH THIS PICTURE??

  12. POSITIONING THE PERSON • PROPERLY POSITIONED AT ALL TIMES • COMFORT • BREATHING EASIER • PROMOTION OF CIRCULATION • PREVENTION OF PRESSURE ULCERS • PREVENTION OF ATROPHY AND CONTRACTURES

  13. POSITIONING THE PERSON • FOWLER’S POSITION • SUPINE POSITION • PRONE POSITION • LATERAL POSITION • SIMS’ POSITION • CHAIR POSITION

  14. CHAPTER 16: MOVING AND TRANSFERRING THE PERSON HEALTH TECH 1 MRS. CARPENTER

  15. Turning and Repositioning • Turn schedules • Move from bed to chair, stretcher or toilet • TRANSFER=moving the person from one place to another.

  16. Preventing work-related Injuries • OSHA recommendations • Manual lifting be minimized in all cases • Manual lifting be eliminated if possible • Moving a person safely is determined by the health team • Dependence level (box 16-2) • Amount of assistance needed • Procedure to use • Equipment needed

  17. LIFTING AND MOVING PERSONS IN BED • Differing abilities of patients • self • two or three people • mechanical lift • Comfort and safety are a priority • Protect the skin during lifting and moving.

  18. LIFTING AND MOVING PERSONS IN BED • improperly moving causes • Friction • rubbing of one surface against another • Shearing • skin sticks to a surface and muscles slide

  19. LIFTING AND MOVING PERSONS IN BED • Reduce friction and shearing • roll or lift the person. • use Turn sheets or special turning pads • Ask co-workers to help before starting the procedure. • Cover and screen the person to protect the right to privacy. • Protect tubes or drainage containers connected to the person.

  20. Procedures • Raising the person’s head and shoulders • Moving the person up in bed • for good alignment and comfort. • move children up in bed alone. • lightweight adults up in bed alone with trapeze. • using a lift sheet with help is best • two workers are needed to move heavy, weak, and very old persons up in bed.

  21. Procedures • Moving the person up in bed with a lift sheet • easier with co-worker help • Friction and shearing are reduced • The procedure is used for: • those who cannot move themselves • unconscious or paralyzed • spinal cord surgery or spinal cord injuries • Older persons

  22. APPLICATION #2 Raising the person’s head and shoulders. Moving the person up in bed Moving the person up in bed with a lift sheet Moving the person to the side of the bed

  23. TURNING PERSONS • Persons are turned toward or away from you. • depends on the person’s condition and the situation. • Turning persons onto their sides • prevent complications from bed rest • After turning • position the person in good alignment. • Use Pillows to support the person.

  24. Logrolling • turning as a unit, in alignment ,one motion • the spine is kept straight. • Procedure used for: • Older persons with arthritic spines or knees • Persons who are recovering from hip fractures • Persons with spinal cord injuries • Persons who are recovering from spinal surgery • Two or three staff members are needed. • A turn sheet is sometimes used.

  25. APPLICATION #3 TURNING TOWARD TURNING AWAY LOGROLLING

  26. SITTING ON THE SIDE OF THE BED (DANGLING) Purpose • increase activity in stages. • after surgery. • coughs • deep breathes • moves the legs in circles • Two staff members may be needed. • If dizziness or fainting occurs, lay the person down. • older adult may become dizzy or faint when getting up too fast.

  27. TRANSFERRING PERSONS • moving the person from one place to another. • by one, two, or three person lifts • Applying transfer belts • supports persons who are unsteady or disabled • Helps prevent falls and other injuries • Applied to the waist to support the person • used for walking with a person.

  28. Applying a Transfer Belt • Rules • Place buckle on the side or toward back. • Ensure proper tightness • Apply over clothing • Remove when procedure is complete

  29. Bed-to-chair or wheelchair transfers • The procedure depends on • the person’s abilities • Condition • size. • If the person cannot assist, a mechanical lift is used. • For hemiplegia transfer on strong side • wheelchair cushions or positioning devices May be used • to prevent pressure ulcers • Maintain posture • prevent the person from sliding forward. • Ask the nurse how to properly use and place the devices.

  30. APPLICATION #4 APPLY A GAIT BELT TRANSFER FROM BED TO WHEELCHAIR

  31. Reposition in a chair or Wheelchair • Considerations • Alignment and safety • Ability of the person • Mechanical lift • Reclining chair • See page 270
