Definitions & Acronyms

Term Description Source
ACH Air Changes Per Hour ASHRAE
Airborne disease A disease that is caused by a pathogen that can be transmitted through the air by very small particles called aerosols, which have the ability to remain suspended in the air over considerable time and distance. ASHRAE
Aerosol generating procedure (AGP) Procedures that are likely to induce coughing. Procedures that are believed to generate aerosols and droplets as a source of respiratory pathogens include positive pressure ventilation (bi-level positive airway pressure [BiPAP] and continuous positive airway pressure [CPAP]), endotracheal intubation, airway suction, high-frequency oscillatory ventilation, tracheostomy, chest physiotherapy, nebulizer treatment, sputum induction, and bronchoscopy. AGPs should ideally take place in an airborne infection isolation room (AIIR). CDC
Aerosol, infectious An infectious aerosol is a system of liquid or solid particles uniformly distributed in a finely divided state through a gas, usually air. (They are small and buoyant enough to behave much like a gas yet they can be filtered out of the gas.) ASHRAE PD
Aerosol, Short-range transmission Transmitting disease by inhalation of aerosols near the source. The distance for this transmission has not been studied beyond two meters. CIDRAP
Age of Air The time that has elapsed after the air enters a space (at any given point.) DMHC
Air change rate Airflow in volume units per hour divided by the building space volume in identical volume units (normally expressed in air changes per hour [ACH or ACPH]) DMHC
Air irritant A particle or volatile chemical in air that causes physiological response when in contact with mucosa in the eye, nose, or throat. DMHC
Air volume migration The volume of air that is exchanged during room entry/exit (through a door-way between a room and the area beyond its door) DMHC
Air, exhaust Air removed from a space and discharged outside the building by mechanical or natural ventilation systems. DMHC
Air, makeup Any combination of outdoor and transfer air intended to replace exhaust air and exfiltration. DMHC
Air, outdoor (1) Air outside a building or taken from the outdoors and not previously circulated through the system;
(2) Ambient air that enters a building through a ventilation system, through intentional openings for natural ventilation, or by infiltration.
DMHC
Air, recirculated Air removed from a space and reused as supply air. DMHC
Air, supply Air delivered by mechanical or natural ventilation to a space that is composed of any combination of outdoor air, recirculated air, or transfer air. DMHC
Air, transfer Air moved from one indoor space to another. DMHC
Airborne droplet nuclei Small-particle residue (5 µm or smaller) of evaporated droplets containing microorganisms that remain suspended in air and can be dispersed widely by air currents with a room or over a long distance. DMHC
Airborne infection isolation room (AIIR) A room designed with negative pressurization to protect patients and people outside the room from the spread of microorganisms (transmitted airborne droplet nuclei) that infect the patient inside the room. DMHC
Airborne infectious agent An airborne particle that can cause an infection. DMHC
Airborne pathogen An airborne particle that can cause disease. DMHC
Airborne transmission Airborne transmission is defined as "dissemination of either airborne droplet nuclei or small particles in the respirable size range containing infectious agents that remain infective over time and distance." An important requirement of airborne transmission is that it can occur only at a long distance from the source, according to the CDC. CIDRAP
Air-cleaning system A device or combination of devices used to reduce the concentration of airborne contaminants, such as microorganisms, dust, fumes, respirable particles, other particulate matter, gases and/or vapors in air. Related term: HEPA Filter. DMHC
ASHRAE American Society of Heating, Refriderating and Air Conditioning Engineers ASHRAE
Bioaerosol Particles or droplets suspended in air that consist of or contain biological matter such as bacteria, pollens, fungi, skin flakes, and viruses. DMHC
Building air infiltration Uncontrolled inward leakage of air (that may contain entrained water vapor) through cracks and interstices in any building element and around windows and doors of a building, caused by the pressure effects of wind or the effect of differences in the indoor and outdoor air density. DMHC
CADR Clean Air Delivery Rate which is the combined effect of actually how much air is moved through the filter and the filter efficiency. AHAM AC-1
CFM Cubic Feet Per Minute  
CFM/P Cubic Feet Per Minute Per person  
Clinical test The collection of information on an individual, usually through the performance of medical tests or physical exams.  
Clinical trial "A clinical study that examines and assesses the effects of a novel treatment, if it is safe, and if it works in people. Clinical trials are classified in 4 phases:

Phase I: The first time a new treatment or vaccine is tested in humans, it will usually be given to a small group of healthy volunteers, usually less than 50 participants. The principal objectives in Phase I are to make sure that the new medicine or vaccine presents no major safety issues, clarify that it can reach the targeted body area, remains there long enough to deliver its benefits, and gain preliminary evidence that it could offer therapeutic value, or prevent the disease or condition.

Phase II: If Phase I is successful, approval will be sought for a trial involving a larger group of people, usually several hundreds of participants. Phase II trials will typically include patients who have the disease the potential medicine is targeting and aim to establish the efficacy of the treatment or vaccine in treating or preventing the disease, and identify the optimal dose.

Phase III: If the results from Phase II are encouraging, a Phase III trial is conducted, which involves several hundreds to several thousands of participants coming from different countries. The objectives in Phase III are to evaluate the safety and effectiveness of the new treatment or vaccine in the typical patient likely to use it in clinical practice and identify side effects. If a new treatment or vaccine completes Phase III with positive results, regulatory approval might be sought.

Phase IV trials evaluate the treatment or vaccine after approval and frequently evaluates longer-term effects or compares effectiveness and safety of the new treatment with effectiveness and safety of established treatments. It typically involves several hundreds to several thousands of participants"
ASHRAE
Contaminant or Pollutant Any impurity, any material of an extraneous nature, associated with a chemical, a pharmaceutical preparation, a phuysiologic principle, or an infectious agent. DMHC
Contaminant, airborne An unwanted airborne constituent that may reduce the acceptability of air. DMHC
Contamination The act of contaminating, especially the introduction of disease germs or infectious material into or on normally sterile objects. DMHC
COVID-19 COVID-19 is the short name for “coronavirus disease 2019" COVID-19. A respiratory illness, formerly known as the 2019 novel coronavirus, caused by the virus SARS-CoV-2. WHO
Cubicle A space intended for human occupancy that has at least one opening and no door and is enclosed on three sides with full height or partial height partitions. FGI
Droplet transmission Droplet transmission is defined as "respiratory droplets carrying infectious pathogens that transmit infection when they travel directly from the respiratory tract of the infectious individual to susceptible mucosal surfaces of the recipient, generally over short distances, necessitating facial protection." Close contact involves hand transfer of surface contamination to mouth, nose or eyes, hand washing and gloves being common controls. CIDRAP
