Core Responsibilities

Primary Functions

Provide continuous, evidence-based bedside nursing care for critically ill patients by performing comprehensive assessments, interpreting physiologic data, and initiating immediate interventions to stabilize airway, breathing, circulation, and neurologic status.
Manage advanced hemodynamic monitoring including arterial lines, central venous pressure (CVP), pulmonary artery catheter data (when applicable), non-invasive cardiac output devices, and trending values to guide titration of vasopressors, inotropes, and fluids.
Initiate and manage mechanical ventilation: set-up, troubleshooting ventilator modes, interpreting ventilator waveforms, performing spontaneous breathing trials, coordinating weaning protocols, and collaborating with respiratory therapy and physicians on ventilator parameters and extubation readiness.
Administer and titrate high-risk medications (vasoactive agents, sedatives, analgesics, neuromuscular blockers, insulin infusions) safely using infusion pumps, double-check procedures, and unit-specific protocols while documenting response and adverse events.
Perform and maintain care for invasive devices including central venous catheters, arterial lines, chest tubes, intra-aortic balloon pumps (IABP), extracorporeal membrane oxygenation (ECMO) circuits (where applicable), and peripherally inserted central catheters (PICCs), ensuring sterile technique and line integrity.
Conduct advanced cardiac rhythm interpretation and respond to arrhythmias; participate as an active member of the code team and lead resuscitation efforts according to ACLS/PALS/NRP guidelines as appropriate to patient population.
Implement evidence-based sepsis recognition and management bundles, including timely cultures, appropriate broad-spectrum antibiotics, fluid resuscitation strategies, and source control communication with the interprofessional team.
Complete comprehensive, accurate, and timely documentation in the electronic medical record (EMR), including assessments, medication administration records, ventilator settings, hemodynamic trends, care plans, and discharge summaries to support continuity and legal requirements.
Prepare patients for and support them during invasive procedures (intubation, central line placement, thoracostomy, bedside imaging) by providing monitoring, sedation management, sterile field assistance, and post-procedure assessment.
Provide family-centered care by delivering clear, compassionate education and updates to patients' families, facilitating goals-of-care conversations with the team, and supporting emotional and decision-making needs during critical illness.
Coordinate and lead handoff communication during shift changes and transfers using standardized tools (SBAR, IPASS) to ensure continuity of care and minimize information loss.
Participate in multidisciplinary rounds, contribute clinical assessments and recommendations, and collaborate with physicians, pharmacists, respiratory therapists, physical therapists, dietitians, and case managers to develop and implement individualized patient care plans.
Apply infection prevention and control practices rigorously, including central line-associated bloodstream infection (CLABSI) prevention bundles, ventilator-associated event (VAE) prevention, catheter-associated urinary tract infection (CAUTI) prevention, and appropriate isolation precautions.
Manage complex pain, agitation, and delirium using validated assessment tools (e.g., RASS, CAM-ICU) and protocols for sedation, analgesia, and early mobility while balancing safety and weaning considerations.
Monitor, draw, and interpret arterial blood gases (ABGs), point-of-care testing, and relevant laboratory results to drive clinical decision-making and adjust respiratory and metabolic support promptly.
Triage and prioritize care for multiple critically ill patients by applying sound clinical judgment, delegation skills, and time management to ensure high-acuity needs are met safely.
Serve as a preceptor and mentor for newly hired ICU nurses and students by providing structured education, competency validation, real-time coaching, and performance feedback to promote clinical excellence and retention.
Lead and participate in quality improvement initiatives and unit-based projects aimed at improving patient outcomes (e.g., reduced readmissions, decreased time-to-antibiotics, improved sedation management) and report metrics to leadership.
Ensure safe transitions of care including ICU-to-stepdown or ICU-to-home planning by coordinating with case management, arranging durable medical equipment, and ensuring clear discharge instructions and outpatient follow-up.
Maintain readiness for emergency responses by participating in mock codes, simulation training, and ongoing skills validation for airway management, vascular access, and advanced cardiac life support protocols.
Provide culturally competent care that respects diversity, privacy, and patient preferences while advocating for patient rights and ensuring ethical practice in end-of-life and complex decision-making scenarios.
Monitor and escalate equipment or safety issues (ventilator alarms, infusion pump failures, supply shortages) promptly to biomedical engineering and leadership while implementing contingency plans to preserve patient safety.

Secondary Functions

Participate in unit education programs by developing and delivering in-service trainings on critical care topics (ventilator management, sedation protocols, sepsis bundles, ACLS updates).
Support data collection for clinical dashboards and quality metrics, contributing frontline insights to performance improvement and regulatory readiness.
Assist in inventory management and equipment checks to ensure immediate access to critical supplies, emergency drugs, and functioning devices.
Contribute to clinical policy and protocol review by offering bedside perspectives that improve workflow, safety, and compliance with evidence-based best practices.
Engage in clinical research or registry participation when available, supporting patient enrollment, data integrity, and adherence to study protocols.
Mentor colleagues on documentation best practices and EMR optimization to reduce charting burden while improving legal and billing accuracy.
Facilitate family meetings and palliative care referrals when appropriate, coordinating with social work and pastoral care to support patient-centered goals.
Support onboarding and competency validation for float or travel nurses to ensure consistent standard of care across shifts.
Assist with bed management and flow coordination during high census periods by prioritizing safe transfers, discharges, and admissions.
Participate in occupational health and staff safety initiatives, including vaccination clinics, exposure reporting, and workplace violence prevention measures.
