Critical Care Nurse

A licensed healthcare professional who specializes in delivering comprehensive, continuous care to patients experiencing acute, life-threatening medical conditions.

Critical Care Nursing

A specialized field of nursing focused on the assessment, management, and support of patients facing severe, life-threatening illnesses, integrating complex physiological monitoring with holistic physical and psychosocial care.

Compassion (7 C's of Critical Care)

Demonstrating genuine empathy and kindness towards patients, understanding their fears and anxieties, and providing emotional support throughout their care journey.

Communication (7 C's of Critical Care)

Dr. Bjørn Ibsen

The anesthesiologist who introduced positive pressure ventilation during the 1950 polio epidemic and founded the first intensive care unit in Copenhagen in 1953.

Dr. John Gibbon

The surgeon who developed the heart-lung machine in the 1950s, enabling complex open-heart operations by temporarily taking over cardiac and pulmonary circulation.

Open Model (ICU)

An ICU organizational structure where primary care physicians and attending specialists retain primary patient management with consulting assistance, typical of smaller community or rural hospitals.

Closed Model (ICU)

An ICU organizational structure where care is managed exclusively by board-certified intensivists, typical of major academic medical centers like Johns Hopkins and the Mayo Clinic.

Transitional / Hybrid Model (ICU)

An ICU organizational structure combining a dedicated on-site intensivist team with ongoing collaborative input from the patient's primary admitting physicians.

Level 0 Care

Standard ward-based hospital care delivered to stable acute inpatients whose medical and nursing needs do not require advanced monitoring or life support.

Level I Care (Enhanced Care)

High dependency unit care designed for patients requiring close observation, resuscitation, or short-term cardiorespiratory support (usually less than 24 hours), with an on-site duty medical officer available.

Level II Care (Critical Care)

General hospital intensive care for patients requiring prolonged mechanical ventilation or single-organ failure management, characterized by a 24/7 duty medical officer and a 1:2 nurse-to-patient ratio.

Level III Care (Critical Care)

Tertiary referral intensive care capable of managing complex multi-system life support (e.g., hemodialysis, neurosurgery, MODS), featuring 24/7 intensivist coverage, a 1:1 nurse-to-patient ratio, and academic research commitments.

Intensivist

A board-certified physician with advanced specialized training in critical care medicine who leads the multidisciplinary ICU team and oversees all clinical operations within the unit.

Patient Advocacy

The professional duty of the critical care nurse to represent the patient's rights, preferences, and clinical interests to the healthcare team, particularly when the patient is unable to speak for themselves.
