A New Artificial Respirator

A Web Application of Simulation System of Artificial Respirator

-A Web application of a ventilator simulation system was developed for the students of clinical engineering and health care professionals. The system runs on Internet Explorer (5.5 or higher) and was developed using HTML, VBScript and Active X control (tklsim.ocx 70kB). The system was composed of a ventilator module and a respiratory model module. The ventilator module makes various waveforms o...

Respirator Donning in Post-Hurricane New Orleans

We evaluated correctness of N95 filtering facepiece respirator donning by the public in post-hurricane New Orleans, where respirators were recommended for mold remediation. We randomly selected, interviewed, and observed 538 participants, using multiple logistic regression for analysis. Only 129 (24%) participants demonstrated proper donning. Errors included nose clip not tightened (71%) and st...

A New Restricted Earth Fault Relay Based on Artificial Intelligence

The restricted earth fault (REF) relay is a type of differential protection which is used for detection of internal ground faults of power transformers. But, during external faults and transformer energization conditions, the probability of current transformer (CT) saturation increases. Thus, the spurious differential current due to CT saturation, can lead to REF relay maloperation. In this pap...

The first few hours off a respirator.

Artificial lungs: a new inspiration.

An estimated 16 million Americans are afflicted with some degree of chronic obstructive pulmonary disease (COPD), accounting for 100,000 deaths per year. The only current treatment for chronic irreversible pulmonary failure is lung transplantation. Since the widespread success of single and double lung transplantation in the early 1990s, demand for donor lungs has steadily outgrown the supply. ...
