  3. Define Weaning • It Is: Removal from Assisted Positive Pressure Ventilation to: • CPAP • T-tube or Trach Mask • Face Mask, Face Tent or Nasal Oxygen • It Is Not: Extubation or Removal of Tubes From the Trachea: • ET Tube • Tracheostomy Tube

  4. Keys to Early Weaning • Therapist Driven Ventilator Management and Weaning Protocols • Rules for Assessing Weaning Readiness • Rules for Selecting Weaning Mode • Rules for Failure to Wean • Rules to Reduce Support During Weaning • Removing Patient From Sedation ASAP • Mobilizing Patient • Separate Extubation Rules and Process

  5. Example of Rules that Trigger a Weaning Assessment • FiO2 <= 0.5 • PEEP <= 10 • Hemodynamically Stable (Off Vasopressors) • Patient Not Paralyzed and Able to Trigger Ventilator • Meets Agreed Upon Timing Rules

  6. NIH-ARDSnet Rules

  7. Example of Weaning Assessment • During Spontaneous Breathing Record • VR, Vt, f/Vt, MIP, VC • If VR < 27 and Vt > 5 ml/kg PBW Give a Trial of Spontaneous breathing • If VR is 28-37 and Vt is > 4 ml/kg go to PS Weaning • If VR >37 or Vt is < 4 ml/kg wait 4-6 hours and recheck

  8. Example of Weaning Failure Rules • Need to Increase FiO2 to > 0.6 to keep SpO2 > 90% • Need to Increase PEEP to > 12 to keep SpO2 > 90% • VR > 37 Breathing Spontaneously • VR > 37 on PS > 20 cm H2O • Vt < 4 ml/kg PBW • Change in Mental Status • pH < 7.25

  9. Example of Rules to Reduce PS During Weaning • Every 2 hours Reduce PS by 2 cm H2O • If VR > 30 Increase PS by 2 cm H20 • If SpO2 < 90% of FiO2 >= 0.6, Increase PS by 5 cm H2O • If PS is > 20 return to A/C • If PS is = 5 Go to CPAP or T-tube

  10. NIH-ARDSnet Rules

  11. NIH-ARDSnet Rules

  12. NIH-ARDSnet Rules

  13. How to Do This Safely • Script the Rules (they do not have to be perfect just acceptable for a starting point) • Have Front Line Test the Rules on One Patient Under Supervision using Rapid Cycle Testing • Find and Correct the Problems with Rules

  14. How to Do This Safely • Retest on Another Patient and Repeat Until the Rules Are • safe • effective • doable in the local environment • acceptable to local clinicians • Spread To Other Patients
