Real-time monitoring of personal exposures to carbon dioxide

Real-time personal protective equipment monitoring system

The use of personal protective equipment (PPEs) in the construction industry is necessary to guarantee the safety of the workers. However, this equipment is not usually worn properly. Nowadays, the only control performed over the use of PPEs consists of a visual inspection. This paper introduces a novel cyberphysical system (CPS) to check in real time how the PPEs are worn by the workers. In or...

Monitoring Exhaled Carbon Dioxide.

In the past few decades, assessment of exhaled CO2 in both intubated and non-intubated patients has evolved into an essential component in many aspects of patient monitoring. Besides the basic assessment of ventilation, exhaled CO2 monitoring can provide valuable patient safety information and critical physiologic data in regard to the ventilation and perfusion matching in the lungs, cardiac ou...

Real-time monitoring of nasal mucosal pH during carbon dioxide stimulation: implications for stimulus dynamics.

Carbon dioxide is a commonly employed irritant test compound in nasal chemesthetic studies because it is essentially free of olfactory stimulus properties. CO(2) is thought to act via hydration to H(2)CO(3) and dissociation to H(+) in nasal mucus, with resulting activation of acid sensors. However, transient changes in nasal mucosal pH have not been documented during CO(2) stimulation in humans...

A Real-time Health Monitoring System for Evaluating Environmental Exposures

Several recent studies have addressed the topic of “exposome”, an approach for evaluating environmental exposures and their influence on human health conditions. Environmental exposures affecting human health range from a combination of factors like air pollution, tobacco smoke, and pollen, to climate, such as heat and humidity. With continued advances in information technology, and the worldwi...
