Study Notes

Intensive Care Unit (ICU) Department

The ICU is a specialized department within a hospital
Provides critical care to patients with severe or life-threatening illnesses and injuries
Staffed by trained healthcare professionals
Equipped with advanced medical technology
Monitors and treats patients requiring close observation and intensive medical care

Role of the ICU Department

Monitors vital signs such as heart rate, blood pressure, and oxygen levels
Uses advanced monitoring equipment to quickly detect changes in a patient's condition
Employs advanced treatments and technologies (e.g., ventilators, IV medications, dialysis)
Provides support to families of patients during difficult times

Multidisciplinary Care

ICU teams consist of critical care physicians, nurses, respiratory therapists, pharmacists, and other specialists
Working together to develop and implement a comprehensive care plan for each patient

Services Provided by the ICU Department

Ventilator Support (mechanical ventilation for patients who cannot breathe on their own)
Medication Management (administration of sedatives, pain relief, and antibiotics)
Nutritional Support (specialized nutrition through IV feeding or feeding tubes)
Rehabilitation Services (assistance with recovery and regaining strength)

Departments of the ICU

Medical ICU (MICU) : Focuses on patients with severe medical conditions
Surgical ICU (SICU): Cares for patients recovering from major surgeries
Neonatal ICU (NICU): Specialized care for premature and critically ill newborns
Cardiac ICU (CICU): Focuses on patients with severe cardiac conditions
Trauma ICU: Focuses on patients who have sustained severe injuries

Increased Mortality Rates and Delayed Treatment Due to Lack of Reliable ICU Services

Critical conditions can worsen rapidly without immediate access to specialized care
Many critically ill patients may not survive if access to ICU services isn't timely

ICU Vital Signs Monitoring Equipment

Heart Rate Monitors: Measures the number of heartbeats per minute.
ECG or EKG: Records electrical activity of the heart, providing information about heart rhythm and function.
Pulse Oximeters: Non-invasive devices that measure heart rate and blood oxygen levels.
Wearable Monitors: Allow for continuous heart rate monitoring.
Blood Pressure Monitors: Measure the force of blood against artery walls.
- Manual: Require stethoscope and sphygmomanometer
- Digital: Automatically inflate the cuff and produce readings
Oxygen Saturation Monitors (Pulse Oximeters): Measures the percentage of hemoglobin saturated with oxygen.
Calibration: Ensures that monitoring devices provide accurate and reliable readings.
Maintenance: Keeping equipment free of dust, checking batteries, and ensuring software is current.

Understanding Cardiac Monitoring Devices: ECG Machines and Telemetry

ECG Machine: Records electrical activity of the heart.
- Electrodes: Small adhesive pads on the skin to record electrical signals.
- Lead Wires: Connect electrodes to the ECG machine.
- Display Screen: Shows ECG waveforms of the heart.
- Printer: Creates a hard copy of ECG readings.
ECG Waveforms:
- P wave: atrial depolarization (contraction of the atria)
- QRS complex: ventricular depolarization (contraction of the ventricles)
- T wave: ventricular repolarization (relaxation or recharging phase of ventricles)
Types of ECGs: Stress Test ECG (monitors heart during physical activity), Holter Monitor (portable ECG for 24/48 hours)

Understanding Ventilators: Modes, Settings, and Techniques

Assist-Control Ventilation (AC): Ventilator delivers pre-set number of breaths, patient can trigger additional breaths.
Continuous Positive Airway Pressure (CPAP): Maintains constant pressure in the airway throughout the breathing cycle.
Bilevel Positive Airway Pressure (BiPAP): Provides two different levels of pressure (IPAP for inhalation, EPAP for exhalation).

Understanding Oxygen Delivery Systems

Nasal Cannula: Delivers low to moderate concentrations of oxygen.
Simple Face Mask: Delivers higher concentrations of oxygen.
Non-Rebreather Mask: Delivers high concentrations of oxygen.
Venturi Mask: Delivers precise oxygen concentrations.
High-Flow Nasal Cannula (HFNC): Delivers heated and humidified oxygen at high flow rates.

Understanding IV Pumps and Infusion Devices

Gravity Pumps: Use gravity to deliver fluids.
Electronic Infusion Devices (EIDs): Provide more controlled and precise fluid delivery.
Programming and Safety Checks: Essential to ensure patient safety.
- Sets flow rate (in mL/hr)
- Tracks the total volume infused
Types of IV Fluids:
- Crystalloids: Small molecules that pass through membranes.
  - Isotonic: Same osmolarity as blood plasma (e.g., Normal Saline)
  - Hypotonic: Lower osmolarity (e.g., 0.45% NaCl)
  - Hypertonic: Higher osmolarity (e.g., 3% NaCl)
- Colloids: Larger molecules that remain in the blood vessels longer (e.g., Dextran, Hydroxyethyl Starch)

Understanding Blood Transfusion Equipment and Protocols

Blood Warmers: Heat blood products before transfusion to prevent hypothermia.
Infusion Devices: Control and regulate blood flow during transfusions.
- Gravity Infusion Sets: Basic devices.
- Electronic Infusion Pumps: Provide precise control over flow rate
Safety Protocols: Double-checking medication orders, monitoring insertion sites, constantly monitoring the patient for adverse reactions.

Understanding Dialysis and Renal Replacement Therapy

Hemodialysis: A procedure that uses a machine to filter waste, salts, and fluid from the blood.
Continuous Renal Replacement Therapy (CRRT): A form of dialysis used for critically ill patients who require continuous treatment.

Monitoring Neurological Function Understanding ICP and EEG in the ICU

Intracranial Pressure (ICP): Measures pressure within the skull.
- Types of ICP Monitors: Invasive methods (e.g., ventriculostomy, subarachnoid bolts) and non-invasive methods (e.g., transcranial Doppler).
Electroencephalography (EEG): Records electrical activity in the brain.
Uses for Monitoring: Diagnosing and managing various neurological conditions, such as seizures, sleep disorders, and encephalopathy.
