Forced air contamination risk in the OR

Introduction:
Forced-air warming (FAW) is a commonly used method of patient warming to reduce perioperative hypothermia and minimize associated surgical complications.
Objectives:
The primary objective of this study was to demonstrate even when properly managed, FAW units may contribute to greater environmental bacterial load and infection risk.
Methods:
A study conducted in 2018 revealed that FAW contamination occurs more than expected in the surgical environment. The study demonstrated that 42.5 percent of the 320 samples collected were higher than the minimum accepted pathogen levels.
Results:
The present study provided a retrospective-research correlation between samples collected in the 2018 analysis, along with evidence of any associated Surgical Site Infections (SSIs).
Conclusion:
In a retrospective study of these cases, 3.4 percent of OB/GYN, 5.6 percent of colon cases, 1.4 percent of GI cases, and 5.3 percent of amputation cases developed an SSI. The results indicate that when FAW is in use, the risk for SSI is present.

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
