This review describes the various types of respiratory protective devices used in Israel during the Persian Gulf war, and summarizes the relevant physiological concepts of respiratory protection. Physiological principles of modern devices with powered air supply are discussed in detail. Our experience may be useful in the evaluation of new respirators and in finding solutions for problematic subpopulations.
Specific physiological interactions among neurons are traditionally attributed to chemical and electrotonic synapses. In the present review we describe a specific synaptic potential that is mediated by K+. It is speculated that this mode of communication might be prevalent in the CNS and has not yet been identified as such in other systems, because the K+ synapse is very similar phenomenologically to chemical and electrotonic synapses. We describe the concept and some experimental manipulations needed to discern the K+ synapse.
