Cardiopulmonary resuscitation (CPR) is a life-saving procedure that can multiply person's chances of survival after cardiac arrest. The effectiveness CPR procedures heavily influenced by the individual skills rescuer providing assistance. Chest compressions delivered at an appropriate depth and rate, allowing full chest recoil with minimal interruptions, are critical for improving arrest surviv...

Three novel air terminal devices (ATDs) for localized ventilation were designed (ATD with perforated inner plate, ATD honeycomb diffuser, and lobbed nozzle). The ability of the ATDs to provide clean breathing zone a person lying in hospital bed was studied. Experiments performed simulated full-scale patient room. A thermal manikin used simulate patient. located above head manikin. Heated dummy ...

We conducted a study assessing the quality and speed of intubation between the Airtraq with its new iPhone AirView app and the King Vision in a manikin. The primary endpoint was reduction of time needed for intubation. Secondary endpoints included times necessary for intubation. 30 anaesthetists randomly performed 3 intubations with each device on a difficult airway manikin. Participants had a ...

The directivity index is a parameter that is commonly used to characterize the performance of directional hearing aids, and is determined from the measured directional response. Since this response is different for a hearing aid worn on a person as compared to when it is in a free field, directivity index measurements of hearing aids are usually done under simulated real-ear conditions. Details...

In this paper, a novel adaptive algorithm for equalization of periodic signals using active control is developed. This algorithm actively cancels out a single frequency without changing the amplitude levels at close frequencies. The algorithm performance is compared with that of an adaptive equalizer previously reported [1][2]. Both algorithms are used for a real multichannel system in order to...

Clothing thermal insulation and moisture vapour resistance are the two most important parameters in thermal environmental engineering, functional clothing design and end use of clothing ensembles. In this study, clothing thermal insulation and moisture vapour resistance of various types of clothing ensembles were measured using the walking-able sweating manikin, Walter, under various environmen...

According to the European prestandard ENV 342:1998, the thermal insulation of cold-protective clothing is measured with a thermal manikin. Systematic studies on the reproducibility of the values, measured with different types of clothing on the commonly used standing and walking manikins, have not been reported in the literature. Over 300 measurements were done in 8 different European laborator...

The video laryngoscope is a useful tool in intubation training as it allows both the trainer and the student to share the same view of the airway during the intubation process. In this study, the Center for Advanced Technology and Telemedicine's airway training program employed videolaryngoscopy (VL) in teaching both simulated (manikin) and human intubation. The videolaryngoscope statistically ...
