[Latent risk and precautions against cross infection at the respiratory disease unit].
To investigate the contamination of respiratory pathogens in the ward of respiratory disease, bacterial count was conducted in air of different rooms of the ward. It was found that the air total bacterial count was much higher in the nursing room and ICU than that in the rooms with good ventilation (P less than 0.01). Pathogens were examined in the saliva of the medical staff. No significant difference was found in the pathogens of the saliva between the COPD patients and medical staff, who were considered as bacteria-carriers. 155 times of bacteriologic examinations were made in 68 humidified bottles for oxygen supplement. All bottles had a mixed contamination, with Pseudomonas aeruginosa being one of common pathogens.
