Banff and Buchan MP Dr Eilidh Whiteford held showdown talks with ambulance bosses last week in the wake of shocking new statistics.
The latest response time figures showed that paramedics took longer than 20 minutes to react to 47 life-threatening incidents in Peterhead in the last year - the worst figures in Scotland.
Dr Whiteford and her MSP colleague Stewart Stevenson were told the Service is re-examing its practices as part of an ongoing review when they met with senior officials on Friday.
The parliamentarians heard that an additional driver is being recruited in Peterhead and shift patterns adjusted to extend coverage, which should relieve pressure on neighbouring stations.
The Scottish Ambulance Service will also undertake a detailed review of the demand profile in North Aberdeenshire forthwith, to assess whether any additional resources might also be required to ensure appropriate standards of performance are met.
Dr Whiteford said: “Having studied the performance statistics and met with various constituents and community representatives over recent weeks, I very much share the concerns that have been expressed.
“We all very much value the work done by our hard working ambulance crews, in what can be extremely demanding circumstances.
“I am therefore absolutely committed to ensuring that they have the support and resources required to provide the quality of service which patients have the right to expect.”
Stewart Stevenson MSP added: “We need to get this right, and I welcome the commitment we received from the Scottish Ambulance Service for a full review of the demand profile in North Aberdeenshire.
“I also welcome the steps which they are already taking to increase provision in the area.”
A further meeting will be held in 12 weeks time.
