38
Q

pacemaker and automated ICD implications for PT

A

internal pacemaker via subclavian vein and ICD

  • usually placed on side of non-dominant UE
  • shoulder flexion and abduction limited to 90 degrees
  • no extreme shoulder extension
  • WB restrictions per MD (may limit use of AD)
  • no pressure in axilla should be applied (particularly during assistance with mobility)
  • temporary pacers do not increase HR with exercise (RPE should be used instead)
39
Q

intra-aortic balloon pump

A
  • used in ICU
  • catheter with balloon attached is placed in aorta via femoral artery
  • increased CO when balloon deflates during systole: increased forward flow with decreases after load
  • increased coronary artery and myocardial perfusion: balloon inflates during diastole directing blood flow backwards into coronary arteries
40
Q

PT implications with IABP

A

-bestrest: usually only increase head of bed height to <30 degrees to avoid trunk/hip flexion on the side of the catheter (no sitting)

Focus of PT intervention:

  • UE and contralateral LE exercises as tolerated (can move ankle and foot of LE with catheter)
  • prevention of pulmonary impairments
41
Q

if intra-aortic balloon pump is dislodged…

pulmonary artery: diastolic= 5-15
pulmonary capillary wedge pressure= 4-15
45
Q

swan ganz catheter (PAC) PT implications

A
  • don’t mobilize pt if pulmonary capillary wedge pressure is being measured.
  • check with skilled professional to determine if OK to get pt up or out of bed
  • if cleared for PT, pt can participate in all therapy including positioning, airway clearance, and mobilization provided the pt is stable
  • keep transducer level at 4th intercostal space for accurate reading during therapy

49
Q

common sites for arterial lines

A

radial artery
femoral artery
sometimes brachial or dorsalis pedis

to avoid kinking line, joint may be immobilized

50
Q

arterial line implications for PT

A
  • WBing is limited and joint movement/ROM near sites of insertion is avoided to prevent dislodging of line
  • if pt is stable and line is secure, the pt can participate in all PT interventions including positioning, airway clearance, and bed mobility
  • if catheter is in a sheath- pt will be on strict bed rest
  • check hospital policies- if femoral line- may be on bedrest (hip ROM limited to 30 deg)
  • standing or gait is uncomfortable with dorsal pedis line
  • always inspect catheter site prior to mobilization and secure if necessary
51
Q

arterial line precautions

A
  • if line is pulled, apply pressure to site immediately and call for help
  • transducer needs to be level to the 4th intercostal space to give accurate reading. will need to be re-calibrated following change in position
  • if transducer is below the heart, displayed BP will be falsely high; if above heart, reading will be falsely low
52
Q

arterial line complications

A

bleeding
infection
lack of blood flow to tissues supplied by artery

53

83
Q

wound vac

A
  • removes slough/exudate from wound, maintains moisture, increases circulation, reduces edema and bacteria
  • can carry machine during tx without disconnecting it (watch battery life!)
  • if disconnecting, must clamp both ends (keep ends clean by using glove/gauze)
  • monitor dressing and seal for breaks
84
Q

compression boots
