Publication number: 20230330379Abstract: An apparatus and method for mitigating release of aerosols from a nebulizer treatment device, or from the respiratory system of a contaminated subject utilizes a mask configured to cover the nose and mouth of the subject, and utilizes a high efficiency filter and fan coupled with an exhaust port of the mask. The fan creates a pressure differential that causes the respiratory products to flow through the high efficiency filter, where aerosols are captured. The mask may further include at least one inlet port for admission of gas (e.g., oxygen) or aerosols. The apparatus provides adequate inhaled oxygen levels and avoids carbon dioxide rebreathing problems.Type: ApplicationFiled: September 1, 2021Publication date: October 19, 2023Inventors: Erica Forzani, Xiaojun Xian, Bhavesh Patel, Kelly McKay

Patent number: 11566801Abstract: An integrated method for assessing metabolic rate and maintaining indoor air quality and efficient ventilation energy use. A physical sensor assesses room occupancy. An actuated ventilation system is set to a constant CO2 level in a predetermined healthy range, where the actuated ventilation system includes a CO2 sensor. The actuated ventilation system sets a first air ventilation rate and the sensor measures a first CO2 level. The system determines whether CO2 level is in a healthy range, if not then the CO2 level is adjusted by setting a subsequent air ventilation rate. A subsequent CO2 level is measured. If the CO2 level is determined to meet a predetermined healthy range, then an assessment of change of air ventilation rate (? ACH) is determined. The determination of air change rate can be further augmented by a physical pressure based measurement. The overall metabolic rate is generated.Type: GrantFiled: January 2, 2019Date of Patent: January 31, 2023Assignee: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Erica Forzani, Nongjian Tao, Francis Tsow
