Aerosol-generating procedure
An aerosol-generating procedure (AGP) is a medical or health-care procedure that results in the production of airborne particles (aerosols) or respiratory droplets, which may be pathogenic.
Aerosol-generating procedures include positive-pressure mechanical ventilation including BiPAP and continuous positive airway pressure (CPAP), high-frequency ventilation, tracheal intubation,[1] airway suction, tracheostomy, chest physiotherapy, nebuliser treatment, sputum induction, bronchoscopy[2] and ultrasonic scaling and root planing.
The term became popular during the 2003 SARS epidemic, where small retrospective studies showed a higher rate of infection amongst healthcare workers in which the procedures had been performed. However this has come under debate in the COVID-19 pandemic. [3]
