Study Notes
ICU Study Notes
Patient Monitoring
- Vital Signs: Continuous monitoring of heart rate, blood pressure, respiratory rate, and temperature.
- Cardiac Monitoring: Use of ECG to detect arrhythmias and ischemia.
- Oxygen Saturation: Pulse oximetry to assess oxygenation levels.
- Neurological Status: Glasgow Coma Scale (GCS) for assessing consciousness.
- Laboratory Tests: Regular blood gas analysis, electrolytes, renal function tests.
Ventilator Management
- Ventilator Settings: Adjust tidal volume, respiratory rate, PEEP, and FiO2 based on patient needs.
-
Modes of Ventilation:
- Assist-Control (AC)
- Synchronized Intermittent Mandatory Ventilation (SIMV)
- Continuous Positive Airway Pressure (CPAP)
- Weaning Protocols: Gradual reduction of ventilatory support; assess readiness based on spontaneous breathing trials.
- Complications: Monitor for barotrauma, volutrauma, and ventilator-associated pneumonia (VAP).
Hemodynamic Assessment
- Monitoring Devices: Use of arterial lines for continuous blood pressure monitoring and central venous catheters for assessing central venous pressure (CVP).
- Cardiac Output: Measurement via thermodilution or echocardiography; assess stroke volume and heart rate.
- Fluid Status: Evaluate using urine output, weight changes, and physical exam findings (e.g., edema).
- Shock Identification: Differentiate types of shock (hypovolemic, cardiogenic, distributive, obstructive) based on hemodynamic parameters.
Nursing Care Protocols
- Daily Assessments: Comprehensive head-to-toe assessments, focusing on changes in condition.
- Infection Control: Strict adherence to hand hygiene and protocols to prevent hospital-acquired infections.
- Sedation and Analgesia: Regular assessment of pain and sedation levels; adjust medications per protocols.
- Positioning: Implement optimal positioning to enhance lung function and prevent pressure ulcers.
- Communication: Provide regular updates to family members regarding patient status.
Critical Care Pharmacology
- Sedatives and Analgesics: Use of drugs like propofol, fentanyl, and midazolam for sedation and pain management.
- Vasoactive Medications: Dopamine, norepinephrine, and dobutamine for managing hemodynamic instability.
- Antibiotics: Administer based on infection type and sensitivities; monitor for efficacy and side effects.
- Blood Products: Criteria for transfusions; monitor for reactions and transfusion-related complications.
- Thromboprophylaxis: Use of anticoagulants to prevent venous thromboembolism (VTE) in critically ill patients.
Patient Monitoring
- Continuous monitoring of vital signs: heart rate, blood pressure, respiratory rate, and temperature.
- Cardiac monitoring utilizes ECG to detect arrhythmias and ischemia.
- Oxygen saturation is assessed with pulse oximetry to monitor oxygenation levels.
- Neurological status is evaluated using the Glasgow Coma Scale (GCS) to determine consciousness levels.
- Regular laboratory tests include blood gas analysis, electrolytes, and renal function tests.
Ventilator Management
- Adjust ventilator settings: tidal volume, respiratory rate, PEEP, and FiO2 according to patient needs.
- Common modes of ventilation include Assist-Control (AC), Synchronized Intermittent Mandatory Ventilation (SIMV), and Continuous Positive Airway Pressure (CPAP).
- Weaning protocols involve gradual reduction of ventilatory support; assess readiness through spontaneous breathing trials.
- Monitor for potential complications such as barotrauma, volutrauma, and ventilator-associated pneumonia (VAP).
Hemodynamic Assessment
- Arterial lines enable continuous blood pressure monitoring; central venous catheters assess central venous pressure (CVP).
- Cardiac output can be measured via thermodilution or echocardiography, evaluating stroke volume and heart rate.
- Fluid status is determined by monitoring urine output, weight changes, and physical exam findings like edema.
- Shock types (hypovolemic, cardiogenic, distributive, obstructive) can be identified based on hemodynamic parameters.
Nursing Care Protocols
- Conduct daily comprehensive head-to-toe assessments, focusing on changes in patient's condition.
- Strict adherence to infection control practices, including hand hygiene, to prevent hospital-acquired infections.
- Regular assessments of pain and sedation levels to adjust medications as per established protocols.
- Implement optimal patient positioning to enhance lung function and reduce the risk of pressure ulcers.
- Maintain clear communication with family members, providing updates on the patient's status.
Critical Care Pharmacology
- Sedatives and analgesics like propofol, fentanyl, and midazolam are used for sedation and pain management.
- Vasoactive medications, including dopamine, norepinephrine, and dobutamine, help manage hemodynamic instability.
- Antibiotic administration is based on infection type and sensitivities, with close monitoring for efficacy and side effects.
- Blood products transfusion criteria are established; monitor for reactions and transfusion-related complications.
- Thromboprophylaxis involves the use of anticoagulants to prevent venous thromboembolism (VTE) in critically ill patients.
