Study Notes
Critical Care
- Critical care, also known as intensive care, is specialized care provided to patients with acute, life-threatening illnesses or injuries.
- Critical care focuses on the treatment and monitoring of individuals in critical or unstable condition, requiring intensive medical intervention and constant observation.
- Care often involves multiple skills and specialties.
- It's the direct delivery of care for a critically ill patient.
- A multidisciplinary service branch of healthcare, where care is optimally delivered by a team of highly trained personnel.
Critical Care Medicine
- Critical care medicine focuses on the diagnosis, treatment, and management of critically ill patients or those experiencing life-threatening medical conditions.
- Often referred to as "Intensive Care Medicine" or "ICU Medicine".
- Critical Care Physicians, known as Intensivists, are highly trained to provide specialized care for patients in a critical condition.
Critical Care Nursing
- Critical care nursing is a specialty of nursing, focusing on providing intensive care to critically ill patients (and their families).
- Specifically deals with human responses to life-threatening problems, like trauma, major surgery, or complications of illness.
- These problems deal dynamically with human responses to actual or potential life-threatening illnesses.
- Human responses can be a physiological or psychological phenomenon.
- Focus includes both the patient’s and family’s responses to illness and involves prevention as well as cure.
- Critical Care Nurses, also known as ICU Nurses or Nurse Intensivists, play a crucial role in delivering specialized care, ensuring patient safety, and supporting the recovery of individuals facing life-threatening medical conditions.
Practitioner Role
- Critical care nurses execute their practice roles 24-hours a day to provide high-quality direct care and indirect care (care of the family) to the critically ill patient.
- Detect and interpret indicators that signify the varying conditions of the critically ill with the assistance of advanced technology and knowledge.
- Plan and initiate nursing processes to its full capacity in a need driven and proactive manner.
- Act promptly and judiciously to prevent or halt deterioration of patients’ condition when conditions warrant.
- Coordinate with other healthcare providers in the provision of optimal care to achieve the best possible outcomes.
- Understand family needs and provide information to allay fears and anxieties.
- Assist families to cope with the life-threatening situation and/or a patient's impending death.
- Provide health education to patient and family to promote understanding and acceptance of the disease process thus facilitating recovery.
- Participate in the training and coaching of novice healthcare team members to achieve cohesiveness in the delivery of patient care.
- Act in the best interests of the patient, as patient advocate.
- Ensure patient safety by monitoring and safeguarding the quality of care which the patient receives.
Management and Leadership Role
- The critical care nurse in her management and leadership role will be able to assume the following responsibilities:
- Performance of management and leadership skills in providing safe and quality care.
- Delivery of effective health programs and services to critically-ill patients in the acute setting.
- Management of the critical care nursing unit or acute care setting.
- Take the lead and supervision of nursing support staff.
- Utilization of appropriate mechanisms for collaboration, networking, linkage-building and referrals.
Role in Research
- The critical care nurse's role in research will entail the following responsibilities:
- Engage self in nursing or other health-related research with or under the supervision of an experienced researcher.
- Utilization of guidelines in the evaluation of research study or report.
- Application of the research process in improving patient care infusing concepts of quality improvement in partnership with other team players.
Principles of Critical Care Nursing
- Critical care nursing is guided by a set of principles and best practices that ensure the provision of high-quality care to critically ill patients.
- Principles guide critical care nurses in delivering high-quality care and encompass various aspects of nursing care in the ICU or other critical care settings.
- Patient-Centered Care: The primary focus of critical care nursing is the patient. Nurses assess and address the physical, emotional, and psychological needs of the patient and their family. Patient preferences and values are respected, and care is individualized to meet each patient’s unique needs and circumstances.
- Comprehensive Assessment: Thorough and ongoing assessment is essential. Nurses continually monitor vital signs, organ function, and other parameters to detect changes in the patient’s condition promptly. Assessment includes not only physical aspects but also psychological and emotional well-being.
- Timely Intervention: Critical care nurses are trained to recognize subtle changes in a patient’s condition and respond quickly to prevent deterioration. Timely interventions may include administering medications, adjusting ventilator settings, or initiating life-saving measures.
- Effective Communication: Communication is crucial within the healthcare team, including nurses, physicians, respiratory therapists, and other specialists. Nurses convey important information, collaborate on care plans, and advocate for the patient’s needs.
- Family-Centered Care: Families play an integral role in the care of critically ill patients. Critical care nurses support and involve families in decision-making and care planning. Communication with families is transparent, compassionate, and respectful.
- Evidence-Based Practice: Critical care nursing is based on the best available evidence and research. Nurses stay current with the latest advancements in critical care medicine and incorporate evidence-based practices into patient care.
- Cultural Competence: Nurses recognize and respect cultural diversity and its impact on healthcare decisions and preferences. Culturally competent care ensures that patients’ cultural beliefs and practices are considered in their care plans.
Invasive Lines
- Central Venous Catheter: A catheter inserted into a large vein, usually in the neck, chest, or groin, to provide access to the central venous system. Used for administering medications, fluids, and blood products.
- Pulmonary Artery Catheter (Swan-Ganz Catheter): A thin tube inserted through a vein in the arm or leg, advancing it through the right ventricle and into the pulmonary artery. Measures pressures and blood flow in the heart and lungs to assess cardiac function.
- Intracranial Pressure Monitor: Measures the pressure of fluid in the brain (CSF) in patients with head trauma or other conditions affecting the brain (such as tumors, edema, or hemorrhaging). Normal ICP in adults is usually between 5 to 15 mmHg. When ICP exceeds the normal range or becomes pathologically high (Intracranial hypertension ICP > 20 mmHg), it can lead to decreased cerebral perfusion, brain damage, and other complications. Monitoring intracranial pressure is crucial in the management of patients with various neurological conditions, traumatic brain injuries, brain tumors, and other conditions that can affect brain function and cerebral perfusion.
Monitoring Devices
- Apnea Monitor: Also known as an apnea alarm or apnea detection device, is designed to monitor a patient’s breathing patterns, especially during sleep or in neonatal and pediatric care settings. It continuously monitors breathing to detect cessation in infants and adults at risk of respiratory failure. The primary purpose of an apnea monitor is to detect and alert caregivers or medical professionals when a patient experiences episodes of apnea, which is the temporary cessation of breathing.
- Arterial Line: Also referred to as a arterial catheter or art line, is used to monitor and measure a patient’s blood pressure continuously and in real-time. A very thin tube (catheter) is inserted into one of the patient’s major arteries, usually the radial artery in the wrist (although other arteries such as the femoral or brachial arteries can also be used), to allow direct measurement of the blood pressure and to measure the concentration of oxygen and carbon dioxide in the blood (SaO2). The arterial line is attached to a monitor.
Medical Equipment
- Ventilator: Also called a respirator, assists with or controls pulmonary ventilation in patients who cannot breathe on their own.
- Defibrillator: A defibrillator is used to “shock” the heart from an abnormal rhythm pattern back into a normal rhythm.
- Infusion Pump: An electronic device used to control the administration of intravenous fluids in very small amounts and at a carefully regulated rate over long periods. It is a device that delivers fluids intravenously or epidurally, including continuous anaesthesia, drugs, and blood infusions.
- Syringe Pump: Syringe pumps, also known as syringe drivers, are designed to deliver medications or fluids in small, precise volumes using syringes as the fluid source. They are often used for high-alert medications that require exact dosing, and are commonly used for infusing critical care medications such as vasoactive drugs (e.g., epinephrine, norepinephrine), sedatives, and other intravenous medications in intensive care units.
