Potok in healthcare
Problem description

Hospital-acquired infections (HAI) 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 the billions of US dollars. However, 30% of all HAI 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. The design of such systems is regulated by the following documents:



Sanitary-epidemiological requirements for organizations engaged in medical activities


GOST R 52539-2006
Clean air in healthcare facilities. General requirements


Federal Law of 30.03.1999 No. 52-FZ
On the sanitary-epidemiological welfare of the population


Federal Law of December 30, 2009, No. 384-FZ
Technical regulations on the safety of buildings and structures


Code of Regulations SP 118.13330.2012
Public buildings and facilities. Updated version of SNiP 31-06-2009


Code of Regulations SP 158.13330.2014

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 (hospital bed turnover increases)

Scientific Research Institute of Pediatric Oncology and Hematology, FSBI N.N. Blokhin Russian Cancer Research Center is one of the largest oncology centers. Hundreds of children from different regions of Russia and other CIS countries are treated here on a regular basis. 

The condition of patients requires special conditions in the rooms where they spend many months of treatment and rehabilitation. The children have such suppressed immune systems that any infection can lead to serious complications.

N.I. Pirogov City Clinical Hospital No. 1 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%
