Children of smokers have more than 5 times higher levels of a nicotine toxin

...luence exposure to passive smoking, such as poorer ventilation or a greater tendency for parents to smoke indoors in winter.’ Sleeping with a parent is a know risk factor for cot death and the authors suggest that one reason for this could be inhalation of, or closeness to clothing or other objects contamina...

Spreading viruses as we breathe

...iration means we can look to better design spaces, ventilation systems and filters," she said. Professor Morawska said the next stage of the research would investigate the global effect of dried droplets in health care facilities to see how viruses were spread around the world. ...

Study identifies risk factors for spread of respiratory infections in hospitals

..."There is a gap in the knowledge of how oxygen and ventilation therapy may promote the spread of infection. Futur...igh flow rate oxygen therapy and positive pressure ventilation in medical facilities and effective ways of ventilating hospitals and clinics to avoid spreading of ...

Opening windows may be the best way of preventing transmission of airborne infection

... has shown that opening windows and doors provided ventilation more than double that of mechanically ventilated n...00. Even at the lowest of wind speeds, natural ventilation exceeded mechanical ventilation. Facilities built more than 50 years ago, characterized by large win...

Rising ocean temperatures, pollution have oysters in hot water

...nt, producing energy for the oyster, including for ventilation and circulation. "We found that mitochondria are very sensitive to cadmium at high temperatures," Lannig noted, suggesting that the higher temperature and cadmium exposure negatively affect the mitochondria's ability to produce energy. Blood o...

Highly concentrated botulinum preparation for cosmetic injections can result in severe illness

...an intensive care setting, provision of mechanical ventilation when indicated, and rapid administration of antitoxin (optimally within 12 hours of presentation) have been associated with improved clinical outcome. Suspected cases of botulism should be reported immediately to local health authorities to facilitat...

Many cleaners, air fresheners may pose health risks when used indoors

...ests were conducted in a 230-square-foot room with ventilation at an ordinary level which provided approximately one air change every two hours. In some tests of terpene-containing products, ozone was introduced into the room at levels mimicking those that could occur in households or offices. The products were...

Study: Paramedics save more lives when they don't follow the rules

... the standard protocol: intubating the patient for ventilation and delivering a shock using a defibrillator. While still attaching the victim to a defibrillator, they did not wait for the device to analyze the patient's heart rhythm, but started fast, forceful chest compressions. "Intubating the patient and wai...

How 'Dirt' Could Educate The Immune System And Help Treat Asthma

...ill decrease the ocean mixing, which decreases the ventilation to the atmosphere of carbon injected into the deep ocean," Jain said. "Our model results show that this effect is more dramatic in the Atlantic Ocean." Sequestering carbon in the deep ocean is not a permanent solution for reducing the amount of carb...

Climate change will affect carbon sequestration in oceans, model shows

Aircraft Cabin Ventilation Influences The Transmission Of Diseases In-flight

Increasing ventilation within aircraft cabins can reduce the spread of in... restrict the spread of airborne pathogens. Proper ventilation within any confined space reduces the concentration of airborne organisms, with one air exchange rem...

New lab technique identifies high levels of pathogens in therapy pool

...uch enclosed pool areas are likely due to seasonal ventilation practices, including closed doors and windows during cold periods, said Pace. Since the study, the rate of air exchange in the pool area has been increased and additional air filters have been installed that have been shown to capture and remove up t...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...ide and low-oxygen amounts, necessitating a better ventilation system. While oxygen is essential for their cells to produce energy, the removal of carbon dioxide from their bodies is equally important to prevent its toxic buildup in tissues. "Even in our own case, our bodies have to supply oxygen to our tissues,...
