母嬰同室使用負離子發生器

通過新生兒鼻粘膜取樣培養數據的觀察,負離子有抑菌,濾菌作用,是醫院內病室空氣淨化,預防呼吸道感染的有力措施。這不但能夠用於母嬰同室房間。也適用醫院其他各科病室,治療室,手術室,ICU 等房間的空氣淨化與消毒是預防醫院感染,實施空氣淨化,消毒又一新的途徑。

Air Quality Investigation at Schools in Hong Kong

Air Quality Investigation at Schools in Hong Kong

Indoor CO2 concentrations exceeded the ASHRAE standard due to overcrowded classrooms and inadequate ventilation. Implementation of more breaks and recesses between classes might alleviate the high level of CO2. The occupancy of classrooms in Hong Kong often exceeded the maximum occupancy of the ASHRAE 62-1989 standard. Decreasing the number of students in each classroom can also lower the CO2 level. Increase the rate of ventilation could remove the accumulated CO2; for example, the use of ceiling fans, exhaust fans could increase the exchange of indoor air with the outdoor.

Treat CNS/Brain Diseases Caused by Low Brain Oxygen/CO2 Levels

Our observation of a reduced functional connectivity during CO2 breathing is consistent with previous reports that light sedation or anesthesia (Deshpande et al, 2010) decreases connectivity in DMN regions, and is also in line with the suggestions that CO2 has a mild sedative effect.

Influence of CO2 on brain activity and metabolism in conscious humans

Our observation of a reduced functional connectivity during CO2 breathing is consistent with previous reports that light sedation (Greicius et al, 2008) or anesthesia (Deshpande et al, 2010) decreases connectivity in DMN regions, and is also in line with the suggestions that CO2 has a mild sedative effect (Fukuda et al, 2006).
