As an Intensive Care Nurse (ICU Nurse), you are a licensed registered nurse who provides advanced, continuous care for critically ill adult or pediatric patients. The ICU Nurse is responsible for complex clinical assessments, life-sustaining interventions (including ventilator and vasoactive medication management), interdisciplinary coordination, family communication, and the accurate documentation and escalation of rapidly changing patient conditions. This role demands strong critical thinking, advanced technical skills, and the ability to perform under pressure while maintaining patient safety and adhering to evidence-based critical care protocols.

Core Responsibilities

Primary Functions

Conduct continuous, comprehensive patient assessments for critically ill patients, interpreting hemodynamic parameters, ventilator waveforms, laboratory data (including ABGs), and bedside monitoring to detect clinical deterioration early and implement immediate interventions.
Manage invasive and non-invasive mechanical ventilation: initiate ventilator settings per protocol, perform ventilator checks and adjustments, implement lung-protective strategies, coordinate spontaneous breathing trials, and lead extubation preparation and post-extubation monitoring.
Administer and titrate vasoactive infusions (e.g., norepinephrine, vasopressin, dobutamine) and titrate sedation/analgesia (e.g., propofol, dexmedetomidine, opioids) based on hemodynamic goals, sedation scales (RASS), and physician orders while monitoring for adverse effects.
Perform and maintain care of invasive lines and devices, including central venous catheters, arterial lines, PICC lines, chest drains, and ensure sterile dressing changes, line maintenance, and prevention of catheter-related infections.
Provide advanced cardiac life support and lead or participate in code responses including high-quality CPR, defibrillation, medication administration per ACLS algorithms, and post-resuscitation stabilization and documentation.
Coordinate and participate in daily interdisciplinary rounds with physicians, respiratory therapists, pharmacists, social workers, and physical therapists to develop, communicate, and implement individualized care plans focused on recovery and goals of care.
Prepare and administer critical care medications, blood products, and complex IV therapies, performing independent double checks and following hospital policies for high-risk medications and transfusion safety.
Perform invasive and bedside procedures under protocol or physician supervision as applicable: arterial blood sampling, assist with central line insertion, endotracheal suctioning, chest tube management, and assist during bedside tracheostomy cares.
Evaluate and implement sepsis bundles and evidence-based protocols (e.g., early sepsis screening, timely antibiotics, source control, fluid resuscitation), documenting time-sensitive interventions and outcomes.
Manage continuous renal replacement therapy (CRRT) or dialysis coordination for hemodynamically unstable patients, ensuring circuit integrity, anticoagulation considerations, and fluid management coordination with nephrology.
Conduct comprehensive family and surrogate communication, delivering complex updates on clinical status, prognosis, and treatment plans; facilitate goals-of-care conversations in concert with physicians and palliative care when appropriate.
Maintain accurate, timely electronic health record (EHR) documentation for assessments, medication titrations, ventilator and device settings, nursing interventions, and multidisciplinary communication, supporting both continuity of care and legal/quality requirements.
Participate in admissions, discharges, and safe in-unit or interfacility transfers of critically ill patients, including preparing ventilator and medication handoffs, completing checklists, and coordinating transport teams and equipment.
Implement infection prevention and control measures in the ICU: isolation precautions, antibiotic stewardship collaboration, central line-associated bloodstream infection (CLABSI) prevention bundles, and ventilator-associated pneumonia (VAP) prevention protocols.
Provide pain, agitation, delirium assessment and management using validated scales (e.g., CAM-ICU, RASS), including non-pharmacologic interventions and pharmacologic adjustments while minimizing oversedation and promoting early mobilization.
Perform ongoing neuromuscular assessment for patients with brain injury, elevated intracranial pressure, or sedation, collaborating with neurology/neurosurgery teams for monitoring and interventions.
Supervise and mentor novice ICU nurses, nursing students, and other allied health staff; serve as a preceptor during orientation and contribute to competency-based evaluations.
Participate in quality improvement initiatives, adverse event reviews, and root cause analyses to improve patient outcomes, reduce complications, and contribute to evidence-based policy and protocol updates.
Ensure availability, functionality, and appropriate use of critical care equipment (ventilators, infusion pumps, arterial/central line pressure transducers, bedside monitors), reporting malfunctions and coordinating repairs or replacements promptly.
Facilitate early mobilization and rehabilitation plans in coordination with physical and occupational therapy to reduce ICU-related deconditioning and support recovery trajectories.
Lead or take part in code blue debriefings, morbidity and mortality reviews, and team training exercises (e.g., simulation drills) to enhance team performance and patient safety.
Support palliative and end-of-life care processes in the ICU, including symptom management, comfort measures, withdrawal of life-sustaining therapies per policy, and documentation of advanced directives.

Secondary Functions

Actively participate in unit-based performance metrics, staffing flexibility, and patient throughput optimization including bed management and discharge planning for critical care patients.
Assist in the development and delivery of continuing education programs and competency refreshers for ICU staff on topics such as ventilator management, ACLS updates, sepsis care, and new device implementations.
Collaborate with pharmacy to review medication safety concerns, participate in medication reconciliation on ICU admission and discharge, and support antimicrobial stewardship efforts.
Contribute to clinical research projects, data collection, and protocol adherence when the ICU participates in trials or quality registries.
Support tele-ICU programs or remote intensivist workflows by providing accurate bedside assessments and facilitating virtual rounds or consultations.
Engage in supply chain and inventory management for critical care supplies, ensuring emergency kits, code carts, and procedure trays are stocked and checked per policy.
Serve on committees (e.g., infection control, patient safety, ethics) to represent bedside nursing perspectives and advocate for practical, patient-centered policy changes.
Participate in disaster preparedness planning, surge management protocols, and rapid expansion of critical care capacity during public health emergencies.
