Study Notes

Intensive Care (ICU) Definition

Intensive care is the highest level of patient care for critically ill patients.
It involves a multidisciplinary and interprofessional approach for managing patients with established or at risk of life-threatening organ failure.
ICU's provide temporary support and replacement for failing organ systems.

Intensive Care Aims

Maintain vital functions of the body.
Prevent further deterioration of the patient's condition.
Reduce mortality rates.
Prevent morbidity in critically ill patients.

Types of Intensive Care Units (ICUs)

ICUs can be categorized by the specific conditions they treat, such as neurological, trauma, burns, medical, and surgical care.
The age group of patients is another factor, including adult and pediatric ICUs.
Specialized intensive care units include:
- Medical Intensive Care Unit (MICU): Manages adult patients with medical illnesses needing frequent monitoring and treatments.
- Surgical Intensive Care Unit (SICU): Focuses on managing postoperative patients requiring continuous monitoring or life support.
- Pediatric Intensive Care Unit (PICU): Manages critically ill children, including those needing postoperative care.
- Neonatal Intensive Care Unit (NICU): Manages premature, high-risk, and critically ill infants, including those with congenital disorders or birth complications.

Equipments Used in ICU

The specific equipment used in ICUs varies based on patient needs, ranging from general to specialized.
Common equipment in ICUs can be grouped into specific categories:

Respiratory Therapies

High Flow Nasal Cannula: Delivers high oxygen concentrations comfortably, used for independent therapy or during breaks from tighter masks.
Non-Invasive Ventilation (NIV): Supports breathing without tubes; uses a tight mask over the nose and mouth connected to a machine providing oxygen or assistance with each breath, improving oxygen levels and reducing carbon dioxide levels.
Endotracheal Tube (ET): A tube inserted through the mouth into the windpipe, for patients with breathing difficulties due to lung problems or those unconscious. Connected to a ventilator.
The Ventilator: Supports breathing with adjustable settings based on patient needs.
Tracheostomy: A surgical procedure creating a hole in the neck and inserting a tube into the windpipe for long-term ventilation or specific patient requirements.
Arterial line: A line inserted into an artery to allow continuous blood pressure monitoring and blood sampling. Connected to the cardiac monitor.
Cardiac Monitor: Displays heart rate, blood pressure, and breathing; alerts should be reported immediately.
Infusion Pumps: Control the amount and rate of medication or fluids administered to patients.
Central Line: Inserted into a large blood vessel in the neck or groin, allowing multiple medications at once and stronger medications.
Nasogastric Tube (NG): Inserts through the nose into the stomach, allowing for feeding when a patient is unable to eat or drink.
Nasogastric (NG) Feed Pump: Delivers feed at a set rate per hour, typically for continuous feeding.

Other Therapies

Total Parenteral Nutrition (TPN): Intravenous nutrition solution, administered by a pump, fulfilling a patient's nutritional needs.
Thrombo-Embolic Deterrent Stockings (TEDS): Long green socks worn to prevent blood clots in the legs.
Intermittent Pneumatic Compression Machine ('flowtrons'): Moves blood to prevent clots forming.
Pressure Relieving Mattress ('Air mattress'): Helps prevent pressure injuries, also known as 'bed sores.'
Urinary Catheter: Placed for monitoring hourly urine output, aiding in assessing fluid balance.
