Door-to-Balloon Time (D2B)

Time from hospital arrival to coronary angioplasty balloon inflation in acute MI

FORMULA

D2B Time = Time of Balloon Inflation - Time of Hospital Arrival (in minutes)

Alternate Calculations

What is Door-to-Balloon Time?

Door-to-Balloon Time measures the minutes from hospital arrival to balloon inflation during emergency coronary angioplasty for acute myocardial infarction (heart attack). This is a critical quality metric for cardiac care. National benchmark is <90 minutes from door to balloon. Every minute reduction in D2B time improves outcomes and survival rates. Indicates emergency response efficiency and cardiac care quality.
