Ensuring adequate and stable hemodynamic conditions is an essential component of patient care in emergency and intensive care units. The assessment of circulatory status is complex and influenced by patient-specific characteristics, medical staff experience, and available equipment. Hemodynamic monitoring encompasses both invasive and noninvasive methods to monitor circulatory parameters. It supports patient management and ensures therapeutic success by alerting healthcare providers to deviations, including critical values. In practice, numerical data often receive more emphasis than comprehensive patient observation, potentially leading to misinterpretation. Advanced practice nurses (APNs) are highly qualified nursing professionals who work largely autonomously due to their advanced training. However, there is currently no uniform legal regulation for these professions in Germany. Clear definitions and nationwide regulations for related academic programs are necessary. Interprofessional collaboration, as well as the qualifications and numbers of nursing staff, significantly impact therapeutic outcomes. Hemodynamics involves the physical principles of blood flow and the assessment of vital parameters to ensure organ perfusion and oxygenation. The competence and knowledge of nursing staff are crucial for safe patient care. Local standard operating procedures (SOPs) should consider interprofessional collaboration and the qualifications of team members.
