Negotiating Bengaluru traffic can be traumatic but the state government has devised a solution, at least for patients needing emergency care. A long-awaited two-wheeler ambulance service was launched yesterday, promising to cut time for patients needing instant response. Equipped with life-saving drugs, oxygen cylinders and trained paramedic drivers, the motorbike ambulances are meant to provide emergency medical care to patients till a fully equipped ambulance arrives. The government promises that 20 minutes is all that will be needed for the two-wheeler ambulances to reach a patient in need.
