Intermittent Mechanical Compression Flashcards

1
Q

Intermittent Mechanical Compression:

A
  • Pneumatic Applies pressure to limb via inflatable sleeve
  • Single compartment=uniform circumferential pressure
  • Multiple compartements=Applies pressure sequentially (greater pressure in distal compartments)
  • Cold can be applied simultaneously - coolant pumped through sleeve

Q

Intermittent Mechanical Compression: Physiological Effects

A
  • Increased interstitial fluid pressure
    • fluids forced into lymphatic and venous return systems
    • = reduced fluid volume in limb

Q

Intermittent Mechanical Compression: Precautions

A
  • Patients blood pressure determines compressive force ratio
  • Never exceed patients DBP or between DBP and SBP depending on brand

Q

Intermittent Mechanical Compression: Application

A
  • 2 hours per day (24 hours)
  • Inflation to deflation ratio:
    • 3:1 edema reduction (45 sec: 15)
    • 4:1 reshape limb
  • Treatment Time
    • 2-3 hrs = lymphedema
    • 2 hrs = traumatic edema
    • 2.5 hrs/wk to 2hrs/d = venous ulcers
    • 1 hr to 1-3x/d = residual limb

Q

Intermittent Mechanical Compression: Pressure Forces

A

Pt’s BP determines setting Some manufacturers redommend the pressure never exceed diastolic Others advise pressure should fall between diastolic and systolic. Numbness, tingling, pain, pulse should not be felt by pt during treatment

Q

Intermittent Mechanical Compression: Treatment Time

A
  • Depends on tolerance
  • Minimum daily treatment:
    • Lymphedema - 2 hrs to two 3 hr sessions
    • Traumatic edema - 2 hrs
    • Venous ulcers - 2.5 hrs/3x/week to two 1 hr periods
    • Stump reduction - 1 hr to 3 hr sessions totalling 4 hrs
