RESEARCH on the problems of machine translation has been going on for several years in this country and abroad. 1 To date it has been concerned primarily with the complicated linguistic problems involved in mechanical translation, since the engineers can probably build the necessary equipment. This article is intended to suggest some of the linguistic problems to the engineer and to explain som...

background. There are a variety of potential hazards with laser technology. methods. A review of the literature. objective. To summarize the potential hazards of CO 2 and erbium laser technologies and the safety guidelines and equipment developed to minimize them. results. Laser hazards can be divided into the following categories: mechanical, environmental, macrobiologic, microbiologic, and ia...

In order to facilitate international multicentre studies and improve the quality control of infant pulmonary function measurements, the European Respiratory Society-American Thoracic Society Task Force for infant lung function testing has recently developed specifications for standardized infant lung function equipment and software. A mechanical infant lung model analogue has been developed to ...

As hospitals begin to implement electronic medical records, the inadequacies of legacy paper charting systems will become more evident. One area of particular concern for respiratory therapists is the charting of mechanical ventilator settings. Our profession's lack of a standardized and generally accepted taxonomy for mechanical ventilation leaves us with a confusing array of terms related to ...

Objective To determine the risk factors associated with stridor, with special attention to the role of the cuffed orotracheal cannula. Methods Prospective analysis of all the intubated patients submitted to mechanical ventilator support from January 2008 to April 2011. The relevant factors for stridor collected were age, weight, size and type of airway tube, diagnosis, and duration of mechanica...

The coupling patterns between the rhythm of a mechanical ventilator and the rhythm of spontaneous breathing were studied in enflurane-anesthetized adult human subjects. The spontaneous breathing pattern was altered in response to different frequencies and amplitudes of forced lung inflations. A 1:1 phase locking (the frequency of the mechanical ventilator is matched by the frequency of spontane...

All electrical systems are susceptible to short circuits and the abnormal current levels they create. These currents can produce considerable thermal and mechanical stresses in electrical distribution equipment. Therefore, it's important to protect personnel and equipment by calculating short-circuit currents during system upgrade and design. Because these calculations are life-safety related, ...

INTRODUCTION Manual (bag) ventilation sometimes achieves better oxygenation than does a mechanical ventilator. We speculated that clinicians might generate very high airway pressure during manual ventilation (much higher than the pressure delivered by a mechanical ventilator), and that the high airway pressure causes alveolar recruitment and thus improves oxygenation. Such high pressure might i...

Lung volume equipment and infection control. J.L. Clausen. ©ERS Journals Ltd 1997. ABSTRACT: As part of the consensus workshop regarding lung volume measurements for the American Thoracic Society and European Respiratory Society, this background paper reviews mechanisms and risks of cross-infection resultant from performing measurements of absolute lung volumes either by body plethysmography, g...

The Non-Intrusive Load Monitor (NILM) measures equipment performance by measuring and analyzing the source power to the equipment at a single point in the electrical system. Previous studies have proven the usefulness of the NILM system in characterizing the state of mechanical systems onboard U.S. Coast Guard vessels and at the U.S. Navy’s Land Based Engineering Site (LBES) in Philadelphia, Pe...
