Perspex Machine XI: Topology of the Transreal Numbers

The transreal numbers are a total number system in which every arithmetical operation is well defined everywhere. This has many benefits over the real numbers as a basis for computation and, possibly, for physical theories. We define the topology of the transreal numbers and show that it gives a more coherent interpretation of two’s complement arithmetic than the conventional integer model. Tra...

Endotracheal extubation.

N Engl J Med 2014;370:e4. DOI: 10.1056/NEJMvcm1300964 Copyright © 2014 Massachusetts Medical Society. Overview Endotracheal extubation refers to the removal of an endotracheal tube from the trachea. This procedure is commonly performed in operating rooms, postanesthesia care units, and intensive care units. This review focuses on extubation of the trachea after general anesthesia and short-term...

Proof Techniques for Adapter Generation

We study the composition and substitution of services from a theoretical perspective. An important notion is the operating guideline of a service y, which is defined as the set of services x such that the result of connecting x and y has a certain desired property. We define several related notions and derive results for them in a general context, thus abstracting from the underlying formalism,...

Endotracheal tube extubation force: adhesive tape versus endotracheal tube holder.

BACKGROUND Adhesive tape is commonly used to secure the endotracheal tube (ETT) in anesthesia and intensive-care settings. OBJECTIVE To determine the force required to extubate when the ETT is secured with adhesive tape or commercially available ETT holders. METHODS We orally intubated a simulation manikin with a standard 8.0-mm inner-diameter ETT, inflated the cuff to 20 cm H(2)O, and mea...
