A deterministic extractor for an elliptic curve is a function that converts a random point on the curve to a random-looking bit-string, which is statistically close to a uniformly random bit-string. The problem of converting random points of an elliptic curve into random bits has several cryptographic applications. In this talk, we propose two simple and efficient deterministic extractors for a...

BACKGROUND Ventilator dependency following coronary artery bypass grafting (CABG) is often associated with significant morbidity and mortality. However, few reports have focused on the independent risk factors for ventilator dependency following CABG. This study aimed to evaluate the independent risk factors for ventilator dependency following coronary artery bypass grafting (CABG). METHODS T...

OBJECTIVE To determine the predictors of weaning from mechanical ventilation after cardiac operation with the Ciaglia percutaneous dilatational tracheostomy (PDT) in our preliminary experience in the use of this technique. METHODS We prospectively analysed 33 consecutive patients (mean age 70.9+/-12.7 years) who underwent PDT in our intensive care unit after cardiac operation. The investigati...

Presented here is the design of Mechanical Ventilator Milano (MVM), a novel mechanical ventilator designed for rapid mass production in response to COVID-19 pandemic address urgent shortage intensive therapy ventilators many countries, and growing difficulty procuring these devices through normal supply chains across borders. This an electro-mechanical equivalent old reliable Manley Ventilator,...

In February, 1982, Chest published an article concerning a new and innovative unit at Bethesda Medical Center in St. Paul, Minnesota. This unit is an Inpatient Service kr patients with chronic respiratory problems who cannot be maintained in a home setting. We have found, however, that with rehabilitation, education and appropriate support services, many of our patients could be discharged. Med...

Indirect evidence from airway pressure recordings in mechanically ventilated patients suggests that the diaphragm exhibits contractile activity beyond that required to trigger a ventilator-assisted breath. We used the diaphragmatic EMG to provide direct evidence of persistent contractile activity and studied the effects of alterations in ventilator-delivered flow rate and tidal volume on the du...

-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...

Ventilator-associated pneumonia remains a major cause of morbidity and mortality in postoperative heart surgery patients. We present a systematic review of the literature on the incidence, risk factors, and prevention of this condition in a population at heightened risk.
