Answer

The following measures can be used to ensure local tissue perfusion:

  • Maintain adequate hydration and core body temperature
  • Minimize the effects of known factors (eg, medications, diseases, other substances, including drug or alcohol usage) that may decrease perfusion
  • Insulate from the cold with the use of skin and scalp coverage
  • Minimize blood flow restriction (eg, avoidance of immobility and constrictive footwear or clothing)
  • Maintain adequate nutrition
  • Use supplemental oxygen in severely hypoxic conditions (eg, >7500 m)
