Case Study Scenario 1: Early Childhood (0-5 years) ********** (
Weaning and Extubation of a Mechanically Ventilated Patient Patient Information: • Name: John Doe • Age: 60 years old • Gender: Male • Height: 5 feet 10 inches (178 cm) • Weight: 75 kg (165 lbs) • Medical History: Chronic Obstructive Pulmonary Disease (COPD), hypertension, and type 2 diabetes mellitus. • Current Diagnosis: Acute exacerbation of COPD • Duration on Mechanical Ventilation: 7 days • High-Risk Patient: for respiratory failure after extubation • Sedation: • paralytic is weaned off, • PRN MSO4 for pain and agitation Current Ventilator Settings: • Mode: Assist-Control (A/C) • FiO2: 40% • Tidal Volume (VT): 450 mL • Respiratory Rate: 10 breaths/min. Total rate 22 • PEEP: 5 cmH2O Recent Clinical Observations: • Blood Pressure: 120/80 mmHg • Heart Rate: 85 bpm • SpO2: 95% on current settings • ABG Results: pH 7.40, PaCO2 45 mmHg, PaO2 85 mmHg, HCO3- 24 mEq/L Assignment: Answer the following 15 questions; I am expecting detailed explanations. Initial Assessment 1. What clinical signs and parameters suggest John Doe may be ready for weaning? 2. List the parameters for each below that can indicate a patient is ready to be weaned toward extubation • Tidal Volume (VT) • Respiratory Rate (RR) • Minute Ventilation (VE) • Rapid Shallow Breathing Index (RSBI) • Maximal Inspiratory Pressure (MIP) • Vital Capacity (VC) Should be more negative than -20 cmH2O 3. Describe the procedure for conducting a Spontaneous Breathing Trial (SBT). 4. What criteria must be met before starting the SBT? 5. Describe the methods preferred for conducting an SBT (e.g., T-piece trial, pressure support ventilation). 6. What are you monitoring on the patient during the SBT? 7. Identify some signs of a successful SBT. 8. Name and explain some factors associated with the failure to wean off the ventilator Criteria for Extubation 9. List the general criteria for extubation a) Airway b) Oxygenation c) Hemodynamics d) Mental status Assessing the patient’s readiness for extubation The patient has been on an SBT for 30 minutes • RSBI 80 • RR 28 • VE 12.6 L/min • MIP-40 • Spo2 94% • HR 98 • Alert and oriented, following commands 10. Does John Doe meet the criteria for extubation? Provide a detailed explanation. 11. What additional assessments or precautions should be taken before proceeding with extubation? Post-Extubation Care 12. List the immediate steps to be taken after extubation. 13. What interventions might be necessary to support John Doe post-extubation? 14. Name a device and settings that could help John Doe transition from extubation without having to be reintubated again 15. List potential complications following extubation and the corresponding interventions.
