Using cognitive load theory to develop an emergency airway management curriculum: the Queen's University Mastery Airway Course (QUMAC).

Emergency airway management requires the simultaneous coordination of clinical reasoning and therapeutic interventions in the complex and time-sensitive setting of emergency resuscitation. The cognitive demand associated with these situations is invariably high and must be taken into consideration when designing training programs for this core professional competency. The four-component instructional design model (4C/ID), based on cognitive load theory, was used to develop a 1-year longitudinal airway management curriculum for Emergency Medicine residents.

Dye-sensitized photooxygenation of the C=N bond. 5. substituent effects on the cleavage of the C=N bond of C-aryl-N-aryl-N-methylhydrazones.

The title compounds are cleaved cleanly at the C=N bond by singlet oxygen ((1)O(2), (1)Delta(g)) yielding arylaldehydes and N-aryl-N-methylnitrosamines. These reactions take place more rapidly at -78 degrees C than at room temperature. The effects of substituent variation at both the C-aryl and N-aryl groups were studied using a competitive method.
