Russia examines ventilator type sent to U.S. after fires kill 6

Moscow has begun investigating the safety of aRussian-made medical ventilator, some of which have been sent to the United States though not used, after six people died in hospital fires reported to involve two such machines.

Five people died at Saint George's Hospital in St. Petersburg on Tuesday, including four in a coronavirus intensive care unit, according to a local lawyer. A source told the TASS news agency that the fire broke outafter a ventilator, used to help severely ill COVID-19 patients breathe, burst into flames in the ward.

A similar fire caused by the same model of ventilator, according to a law enforcement source speaking to TASS killed one person in a hospital in Moscow on Saturday.

Roszdravnadzor,Russia's health-care watchdog, said it would check the quality and safety of the ventilators in the two hospitals, and the St. Petersburg hospital said it would stop using the model in question for now. At least twoRussian regions toldRussian news agencies they would also suspend use of the ventilators.

The manufacturer urged people to avoid rushing to conclusions.

The model in question, the Aventa-M, was among those sent to the United States fromRussiaat the start of April to help cope with the coronavirus pandemic. It is made by a firm that is under U.S. sanctions.

The ventilators were never deployed to hospitals in the United States, said Janet Montesi, a spokespersonfor the U.S. Federal Emergency Management Agency (FEMA). The machines were delivered to New York and New Jersey, the U.S. states hardest hit by the virus, but "the flattening curve meant these ventilators were not needed," she said.

The states are returning the ventilators to FEMA, and the investigation by theRussian authorities will help the agency's decision on any future use, Montesi said.

Ventilator new, news agency reports

The Ural Instrument Engineering Plant (UPZ) in Chelyabinsk, 1,500 kilometres east of Moscow, confirmed that the Aventa-M was one of its products and had been supplied to Saint George's Hospital.

"We have no official data about which devices were installed in the zone of the (St. Petersburg) fire," a spokesperson added.

Russiais relatively well stocked with ventilators, and has increased domestic production since the coronavirus outbreak.

Data experts and some medics say many machines in use outsideRussia's big cities are old, but TASS said the ventilator in St. Petersburg was new and had been installed this month.

Radio-Electronic Technologies Concern (KRET), which controls UPZ, said its ventilators had passed all the necessary tests and had been used by medical facilities inRussiasince 2012 without any safety concerns.

"We're looking at different scenarios: the state of the [electricity]network, the medical institutions' engineering infrastructure, the medical equipment, and compliance with fire safety rules," it said in a statement. "We call on the media and other interested parties not to rush to conclusions and wait for the results of official checks."

U.S. firms and nationals have been barred from doing business with KRET since July 2014.

Russiahas reported 232,243 cases of the novel coronavirus and 2,116 deaths.
