Final Exam: Modalities Flashcards
Whirlpool is a type of _____ modality
hydrotherapy
What are the 7 effects of whirlpool on wounds
Cleanses wound mechanical debridement softens hard eschar non-selective hydrates wound thermal effect neuronal effects
What are the 4 indications for using whirlpool for a wound
dirty wound
loosely adherent necrotic tissue
exudate
extensive psoriasis or burns
7 Contraindications of using whirlpool on a wound
health granulation tissue Cardiovascular or pulmonary compromise Plebitis, renal failure Temperatured Lethargic Venous ulcer/position Arterial insufficiency
What are the 4 effects of pulsatile lavage with suction
cleansings
debridement
suction with negative pressure
positive impact pressure
What are the 3 indications of using pulsatile lavage with suction on a wound
if there’s an infection
to remove debris
need something portable
What are the 2 contraindications of pulsatile lavage with suction
is not a sterile process
not going to work with yellow adherent eschar
When should a clinician should stop using pulsatile lavage with suction
If there is no increase in granulation tissue after 1 week or if there’s no decrease in necrotic tissue after 1 week
What is the pressure of pulsatile lavage
14-15psi
Ultrasound has mechanical vibration transmitted greater than _____ kHz
20
Low frequency ultrasound should be used as an adjunct to _____ soft tissue
necrotic
High frequency ultrasound should be used as an adjunct to higher pressure ____ injuries
infected
Which phase of healing should ultrasound be done in
The acute inflammatory phase
What are the three effects of ultrasound
thermal
cavitation bubbles
acoustic streaming
Why do cavitation bubbles appear with ultrasound
They occur when there is a sudden drop in pressure
What are the 4 acoustic streaming effects of ultrasound
increases circulation
alters cell membrane
promotes angiogenesis
may accelerate inflammatory phase
What are the indications for ultrasound
chronic diabetic foot ulcers
pressure ulcers
absence of inflammatory phase
What are the contraindications of using ultrasound on a wound
pregnancy malignancy vascular abnormalities DVT Emboli acute wound infections fractures
What is negative pressure wound therapy
an open cell foam dressing in wound cavity and applying controlled sub atmospheric pressure 125mm Hg below ambient pressure
What are the 6 effects of negative pressure wound therapy
increases vascular perfusion removes excess fluid decreases bacterial colonization increases rate of granulation enhances epithelial migration increases flap survival
