22mm Circuit Tubing and Closed Suctioning: Reducing Infection Risks

标题:22mm Circuit Tubing and Closed Suctioning: Reducing Infection Risks


Infections acquired in healthcare settings are a major concern worldwide. According to the World Health Organization, at any given time, over 1.4 million people worldwide suffer from infections acquired in hospitals. These infections not only cause significant morbidity and mortality but also lead to increased healthcare costs. The need for effective infection prevention measures is more critical than ever. In this article, we will explore the significance of using 22mm circuit tubing and closed suctioning in reducing infection risks.

Importance of Infection Control:

Effective infection control measures play a crucial role in preventing the spread of infections and protecting patients, healthcare workers, and visitors. Proper hygiene practices, sterilization techniques, and the use of appropriate medical equipment are key components of any infection control program. In the case of respiratory care, the use of 22mm circuit tubing and closed suctioning has shown promising results in reducing infection risks.

Reducing Cross-Contamination:

Cross-contamination is a major concern in healthcare settings, especially for patients on respiratory support. Traditional open suctioning methods can increase the risk of bacterial or viral contamination within the respiratory circuit. 22mm circuit tubing refers to the wider diameter of the tubing used in mechanical ventilation systems. The larger diameter reduces resistance to airflow and allows for easy movement of the patient’s secretions through the system. This reduces the chances of secretions depositing on the inner surface of the tube and minimizes the risk of dissemination of microorganisms.

Closed Suctioning: A Game-Changer:

Closed suctioning is a technique that allows for the removal of secretions from the patient’s airway without disconnecting the ventilator circuit. This minimizes the risk of exposure to potentially harmful pathogens. The use of closed suctioning systems has been shown to significantly reduce the incidence of ventilator-associated pneumonia (VAP), a common and severe infection in mechanically ventilated patients.

Benefits of Using 22mm Circuit Tubing and Closed Suctioning:

1. Reduced Infection Rates: Studies have demonstrated a lower incidence of VAP when utilizing 22mm circuit tubing and closed suctioning. This reduction in infections not only improves patient outcomes but also decreases the financial burden on healthcare systems.

2. Improved Patient Comfort: The wider diameter of 22mm circuit tubing allows for better air delivery, reducing resistance and promoting efficient ventilation. This can lead to improved patient comfort and better compliance with respiratory therapy.

3. Time and Cost Savings: Closed suctioning techniques eliminate the need to interrupt mechanical ventilation during suctioning, reducing procedure times and associated costs. Additionally, the reduced incidence of VAP decreases the length of hospital stays and the need for additional treatments.


Infections acquired in healthcare settings continue to pose a significant challenge for patients and healthcare professionals. Implementing effective infection control measures is essential, and the use of 22mm circuit tubing and closed suctioning has emerged as a valuable strategy. By reducing the risk of cross-contamination and ventilator-associated infections, patients can experience better outcomes while healthcare systems save time and resources. As we strive to provide the highest quality of care, incorporating these innovative approaches is crucial in reducing infection risks and improving patient safety.
