The following respiratory infection factors and nursing interventions have a very close relationship with the infection. One should avoid excessive walking around and restrict visits. The ward's winter temperature should be appropriately maintained at 18-20°C, with 50-60% relative humidity. The sick room should have timed window ventilation, lasting every 30 minutes to keep warm during winter ventilation. Every day, mop the floor with disinfectant, wipe surfaces, and if necessary, conduct air disinfection and air bacteriological monitoring.
3.5 Suction: Gently attract the airway for each operator who must follow the principles and avoid violent actions to prevent mucosal damage; the suction tube used should be sterile, soft, porous, and transparent. Prohibit repeatedly suctioning up and down to prevent pathogenic microorganisms in the oral cavity from entering the airway.
3.6 Oral Care: Proper oral care is an effective means to reduce oral colonization and prevent bacterial migration that causes lung infections. Therefore, patients should receive oral health guidance, and they should be encouraged or assisted to clean their mouths after eating. For fasting, feverish, or comatose patients, oral care should be provided daily.
3.7 Disinfection of Respiratory Therapy Equipment: Respiratory therapy equipment must undergo serious and strict cleaning, sterilization, or disinfection before use. If conditions allow, disposable utensils should be used.
