The study was conducted over 30 months with more than 100,000 patient-days. Following implementation of advanced air purification technology, HAIs at St. Mary’s went from an average of 11.9/1,000 patient-days to an average of 6.6/1000 patient-days — a 45% reduction.
For spaces that may have high levels of total volatile organic compounds (TVOCs), the Carrier air monitor includes a sensor that detects the concentration of such compounds, which can be emitted as gases from certain solids or liquids and may be linked with potential health concerns.
As with all electronics, VFDs have advanced in capability and function over their long history, providing more system control to help eliminate external devices and integrate with programmable logic controllers (PLCs).
The newest addition, the AirAssure™ 8144-2, a two-gas model designed to help end users understand and manage common indoor air pollutants utilizes low-cost sensor technology to continuously monitor carbon dioxide (CO2), total volatile organic compounds (tVOC), particulate matter (PM), and other indoor air conditions.
