Thermal & Vascular Physiology Laboratory

Research in the Thermal and Vascular Physiology Laboratory focuses on neural control of the cardiovascular system and how different stressors influence that control in healthy, diseased, and injured individuals, such as:

  • Identifying the consequences of severe burn injuries and subsequent skin grafting on the ability of the burn survivor to regulate internal temperature and cardiovascular function.
  • Understanding the consequences of aging on cardiovascular stress during simulated heat waves.
  • Exploring cooling modalities to attenuate thermal and cardiovascular stress.
  • Understanding how analgesics used on the battlefield affect autonomic control of blood pressure during hemorrhage.
Interests
  • Dr. Crandall’s research interests revolve around neural control of the cardiovascular system, with emphasis on how thermal stress modifies this control.
  • Research areas range from integrative thermoregulatory studies in healthy and unique populations (e.g., skin graft patients) to mechanistic studies on the skin microcirculation.
Clinical applications of this work include:
  • Improved blood pressure control during hemorrhage (particularly in heat stressed individuals such as soldiers, construction workers, etc.).
  • Improved temperature regulatory capacity injured/diseased individuals (e.g., skin graft patients, congestive heart failure, etc.
Current Projects
  • Effects of burn injuries on thermoregulatory and cardiovascular responses in soldiers.
  • Cooling modalities to attenuate thermoregulatory and cardiovascular stress in burn survivors and the elderly.
  • Mechanisms by which heat stress compromises blood pressure control during hemorrhage.
  • Effects of battlefield analgesics on tolerance to hemorrhage.
