Health Secretary Nicola Sturgeon said the Aberdeen Royal Infirmary was the only Scottish hospital which had adult ECMO machines and staff trained in their use.
The ECMO process (extracorporeal membrane oxygenation) is for patients whose heart or lungs do not function properly.
Previously, Scotland had ECMO equipment for adults in Aberdeen but no staff trained in their use and Scottish patients needing this treatment were send to Leicester.
One Scottish swine flu victim, pregnant Sharon Pentleton, received ECMO treatment in Sweden because no beds were available in Leicester, and later made a full recovery.
Today Ms Sturgeon told MSPs: "I can confirm today that over the past week, adult respiratory ECMO has been provided at Aberdeen Royal Infirmary on two occasions.
"Aberdeen Royal Infirmary is currently the only site in Scotland where there are both respiratory adult ECMO machines and staff who have been trained by Leicester in their use.
"The decision to provide ECMO for the two patients in Aberdeen as taken after close clinical consultation with the Leicester team and indeed those consultations are ongoing."
Ms Sturgeon gave the news to MSPs in a ministerial update at Holyrood on swine flu. She told them she met Ms Pentleton and her newborn son last week and reported that both are in “excellent health”.
Ms Sturgeon said an expert group has recommended that while Leicester should at present remain the "front door" for adult ECMO treatment, it could be provided in Aberdeen in future but only when extra capacity was needed.
The Health Secretary told MSPs that last week an estimated 19,200 people contracted swine flu, compared to 14,600 the week before. Since the outbreak began, a total of 556 people have been admitted to hospital, 176 of them in the last week.
As of yesterday there were 65 people in hospital confirmed as having the H1N1 virus, 23 of whom were in intensive care. A total of 25 people have died, four of them in the last week.
Ms Sturgeon also told MSPs that 165,000 doses of vaccine had so far been supplied to health boards with the number set to rise to nearly 250,000 by Monday and 367,000 by next Friday.
From this week GPs had started to receive initial supplies, and all GP practices would have received their initial supplies by the end of next week. First to be vaccinated are vulnerable hospital patients and frontline health and care workers.
Ms Sturgeon said uptake of the vaccination has been “good” and it is expected 1.3 million people in the priority groups will have been offered vaccination by Christmas.
Ms Sturgeon also said there had been a "consistent but gradual" rise in swine flu. Scientists say the worst case scenario might see 12% of the population affected - down from the 30% figure in the previous planning assumptions.”
"Furthermore workplace absences are now projected to be up to 5% rather than 12% as previously indicated."
