Recognize and respond to life-threatening events by following BLS/ACLS protocols, initiating emergency measures (CPR, defibrillation) when qualified and as needed, and supporting the resuscitation team in high-acuity scenarios.
Participate in radiation safety practices for fluoroscopy-supported procedures: monitor dose limits, use shielding, maintain appropriate distance, and document radiation exposure per facility policy.
Maintain inventory of sterile supplies, disposables, and specialty catheters; restock procedure carts, perform daily counts, and place orders to ensure uninterrupted lab operations.
Perform specimen collection, labeling, and handoff for pathology and microbiology (e.g., biopsies, cultures), ensuring chain-of-custody and correct documentation for downstream analysis.
Provide patient and family education on test procedures, expectations, activity restrictions, and follow-up care to reduce anxiety and improve compliance with diagnostic pathways.
Participate in departmental quality assurance and performance improvement initiatives by collecting data, auditing test quality, tracking key performance indicators (KPIs) such as turnaround time and repeat rates, and implementing corrective actions.
Mentor and precept new staff, students, and trainees in cardiovascular techniques, safety protocols, and documentation standards to elevate team competency and ensure consistent care delivery.
Support clinical research and registry projects by collecting protocol-specific data, obtaining informed consent assistance when allowed, and maintaining accurate logs for device studies and quality registries.
Maintain competency through continuing education, recertification, attendance at in-service training, and staying current with evolving cardiovascular technologies and best practices.
