Potok in healthcare
Problem description

Hospital-acquired (or nosocomial) infections are some of the most critical problems in modern healthcare. Each year, 5-10% of hospital patients suffer from them. The economic damage is estimated in billions of US dollars. COVID-19 only made things worse.

However, 30% of all nosocomial infection cases can be completely avoided. In particular, those that depend on air quality. Treating air that passes through ventilation and conditioning systems in healthcare facilities plays an important role in preventing nosocomial infections. Main targets of air decontamination with Potok units are:


To prevent nosocomial infections (including COVID-19) spread


To decrease the number of after surgery complications


To protect the staff from dangerous air-borne microorganisms


To improve patient safety


To increase hospital bed turnover


To reduce equipment maintenance costs

Result of using the Potok equipment

The air supplied to the rooms of healthcare facilities is decontaminated with the Potok equipment with a microorganism inactivation efficiency at the outlet of at least 99%, followed by high efficiency filtration (similar to filters H11-H14). This ensures the air is microbiologically safe, and as a result:

The risk of nosocomial infections decreases
Treatment effectiveness increases
The recovery process is accelerated

Main Military Clinical Hospital named after Burdenko  is one of the largest multidisciplinary medical centers in Russia, the flagship of Russian military healthcare. 

by 1.4 times
the likelihood of developing sepsis was reduced

probability of developing septic shock and multiple organ failure was reduced

The Ostbayerische Technische Hochschule Amberg-Weiden is one of the younger universities of applied Sciences in Germany. At the two locations in Amberg and Weiden, more than 40 bachelor's and master's degree programs, as well as part-time degree programs, are offered at four faculties.

In order to examine the influence of the Potok units on the bacterial burden of the room air and therefore the decontaminating capacity, these experiments were initial performed without the Potok devices to obtain the background contamination of the research OR. Then the Potok units were switched on and after 24 hours a second identically measurement was done.

by 40%
total microbial count in OR table zone was reduced
by 20%
total microbial count in instrument board zone was reduced
by 2.4 times
total microbial count in OR perophery was reduced
by 17.8 times
total microbial count in the lock chamber before the rooms was reduced

City Clinical Hospital No. 1 named after Pirogov is one of the leading multidisciplinary hospitals in Russia. The institution has been providing medical care to those in need for over two centuries.

Since 2006, the air in the operating and intensive care rooms in the 5th surgical ward of the hospital has been cleaned by the Potok equipment built into the ventilation systems.

For more than 10 years, air contamination levels in these rooms have been within the limits set by sanitary and epidemiological regulations, and the share of postoperative complications has not exceeded 0.15%.

The level of postoperative wound purulent-septic complications:
3.5 - 4%
