Projected financial impact of room air humidification for a 250-bed hospital

Next steps for healthy humidification in your hospital 1 Record HAIs • Accurately monitor patient adverse events, especially HAIs Monitor indoor air quality throughout the facility 2 • A key starting point is understanding existing indoor RH and how it varies throughout the hospital Identify weaknesses in building envelope and HVAC systems 3 • Look for areas which can be improved • Consult healthcare humidification experts Install appropriate humidification systems 4 • Energy efficient • Hygienic Continue monitoring both indoor air RH and patient outcomes 5 • Assess impact of proper indoor air hydration on patient outcomes and length of stay • Perform ROI analysis
