Principles of Infection Prevention

Infection control in respiratory care protects patients staff and the community by reducing transmission of respiratory pathogens through administrative engineering and personal protective measures. Administrative controls include policies for screening isolation and for cohorting while engineering controls involve ventilation filtration and negative pressure rooms when available. Personal protective equipment such as masks eye protection gowns and gloves reduces exposure during aerosol generating procedures and strict hand hygiene remains foundational. Training and competency assessment ensure consistent application of measures and surveillance of healthcare associated infections informs targeted interventions and resource allocation.

Procedures with High Transmission Risk and Mitigation

Procedures such as noninvasive ventilation aerosol therapy suctioning and bronchoscopy increase risk of airborne spread and require enhanced precautions including use of airborne infection isolation rooms when feasible and use of respirators for staff. Minimizing room traffic using closed suction systems and using in line nebulization for ventilated patients reduce environmental contamination. When single rooms are unavailable cohorting patients with the same pathogen and scheduling high risk procedures at the end of the day to allow thorough cleaning are pragmatic strategies. Clear communication with infection control teams and with bedside staff ensures that mitigation measures are practical and that patient care is not compromised.

Cleaning Disinfection and Equipment Handling

Cleaning and disinfection of respiratory equipment follows manufacturer guidance and institutional policies to avoid damage while ensuring effective decontamination and single use items are discarded appropriately. Reusable items such as nebulizers circuits and masks require validated cleaning and high level disinfection or sterilization depending on intended use and risk. Storage of cleaned equipment in protected environments prevents re contamination and documentation of cleaning cycles supports traceability. Staff training on proper donning and doffing of protective equipment and on safe handling of contaminated items reduces occupational exposure and supports a culture of safety.
