How to prevent cross infection during sputum aspiration and the process in ICU？ The methods to prevent cross infection during sputum aspiration and during the process in the ICU include: Strictly adhere to hand hygiene standards: Medical staff must disinfect their hands before and after suction and other operations to ensure cleanliness. Use of personal protective equipment: Medical staff should wear personal protective equipment such as masks, gloves, and goggles when suctioning to prevent cross infection caused by respiratory secretions splashing. Strictly adhere to sterile operating procedures: suction tubes and other related instruments must be sterile, and medical staff should avoid contamination during operation. Single person use: The suction tube and other instruments should be used by a single person to avoid cross infection caused by multiple people sharing. Regular cleaning and disinfection: Sputum suction devices and related equipment should be cleaned and disinfected regularly to avoid bacterial growth. Emphasis on education and training: Medical staff should receive relevant infection control training to understand how to perform sputum suction correctly and how to prevent cross infection. Through the implementation of the above measures, the risk of cross infection during sputum aspiration and the process in the ICU can be effectively reduced, ensuring the safety of patients and medical staff.
