Q

Heart transplant HR response

A

Higher resting HR (90-110 bpm)

ECMO

A

Short term- days to weeks , waiting for organ recovery

For management of lfethreatening cardiac failure when no other form of treatment has been or is likely to be successful
- veno-arterial: venous blood diverted from RA, pumped across a membrane oxygenator and heat exchanger, then back to aortic arch

For ventilatory support
- veno-venous: venous blood withdrawnn from RA, circulates through CO2 scrubber and membrane ooxygenator, blood returned via cannula and directed through tricuspid valve

- squeezing gastroc during dorsiflexion

74
Q

Arterial disease

Ankle Brachial index

A

To distinguish neurologic vs vascular (claudication) LE pain

Compares ratio of systolic BP or arms and legs
- use doppler US for legs on posterior tibial artery or dorsalis pedis

Cause and respiration flow rates

A

Cause: environmental irritants- smoking

Obstruction to air flow- narrowing of bronchi and bronchioles from inflammation- spasm
- mucous collection

Functional residual capacity, residual volume and total lung capacity increased

Decreased expiratory flow rates

84
Q

Decreased Expiratory air flow

A

Decreased elastic recoil (pressure to push air out)

Increased resistance through spasm, inflammation

Over-inflated lungs, barrel chest

Increased respiratory work

Overtime as we try to push air out but more and more of our residual volume inc we end up with over inflated lungs & what we refer to a barrel chest

85
Q

Decreased alveolar surface Area

A

Destroyed alveolar walls-> opening of alveolar become enlarged which results in less cross-sectional area for exhange to occur—> results in low “O” in blood hyxemia

-vasocontriction of pulmonary arteries

Increased work for R ventricle

-cor pulmonale

86
Q

A

If low look at CO2

  • if high = respiratory cause
  • then BE for compensation : acute oor chronic, fully or partially compensated

-if not caused by high CO2, it it metabolic acidosis
-if low lungs are trying to compensate
Less CO2= less H+= inc pH

123
Q

Patient chart in front of you pH is high what do we expect….

A

If high, look at CO2

  • if low CO2, respiratory cause
  • BE- probably not time to compensate

-if CO2 is high, lungs are trying to compensate
-fully or partially compensated
