Decay in Physiologic Knowledge since Medical School among Critical Care Fellows (DIP Study).

Rapid accumulation of knowledge and skills by trainees in the intensive care unit assumes prior mastery of clinically relevant core physiology concepts. However, for many fellows, their foundational physiology knowledge was acquired years earlier during their preclinical medical curricula and variably reinforced during the remainder of their undergraduate and graduate medical training. We sought to assess the retention of clinically relevant pulmonary physiology knowledge among pulmonary and critical care medicine (PCCM) and critical care medicine (CCM) fellows.

Avalanche burial pathophysiology - a unique combination of hypoxia, hypercapnia and hypothermia.

For often unclear reasons, the survival times of critically buried avalanche victims vary widely from minutes to hours. Individuals can survive and sustain organ function if they can breathe under the snow and maintain sufficient delivery of oxygen and efflux of carbon dioxide. We review the physiological responses of humans to critical avalanche burial, a model which shares similarities and differences with apnoea and accidental hypothermia.
