Radiographers for bedside X-ray photography Specific radiographers need to be arranged to carry out bedside X-ray photography in key areas and take standardized photography. These radiographers are required to strictly implement the secondary level of protection. In the case of work that may cause spraying or splashing of respiratory secretions and substances of the body, such as sputum aspiration, respiratory sampling, endotracheal intubation, and tracheotomy, the third level of protection is required. After each examination, the surface of equipment should be disinfected (wiped with 75% ethanol).
