The document discusses quality indicators and door-to-balloon (D2B) service in the cardiac cath lab department of Bona Dea International Hospital. It defines D2B as the time from a patient's arrival in the emergency department to when a catheter guidewire crosses the culprit lesion in the cath lab for STEMI patients. American Heart Association guidelines recommend a D2B time of no more than 90 minutes. The document outlines steps to implement D2B service, such as early identification of STEMI patients, alerting the cardiac team, rapid transfer to the cath lab, and reducing door-to-needle times. Following a code STEMI pathway and coordination between team members can help reduce D2
