Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask or nasal mask. Learn more about NIV in this presentation by Dr Somnath Longani, consultant Anaesthesiologist & Intensivist, Midland Healthcare & Research Center, lucknow

New Ventilator Modes: Do They Help?
1. New Ventilator Modes Do They Help? Dean Hess PhD RRT Assistant Director of Respiratory Care Massachusetts General Hospital Associate Professor of Anesthesia Harvard Medical School Editor in Chief Respiratory Care
7. volume from ventilator = set tidal volume calculate new pressure limit pressure limit based on V T Trigger patient or ventilator Time = set inspiratory time cycle off yes yes no no same pressure limit PRVC, VC+, autoflow, APV (pressure-controlled breath) (first breath problem)
8. volume from ventilator = set tidal volume calculate new pressure limit pressure limit based on V T Trigger Pressure or Flow flow = % of peak flow cycle off yes yes no no same pressure limit Volume Support (pressure support breath) (first breath problem)
9. Adaptive Control: PRVC, AutoFlow, VC+ Effect of compliance increase (or effort increase) Branson, Respir Care 2005;50:187 Effect of compliance decrease (or effort decrease) The ventilator can take away support if patient effort increases! Tidal volume limitation is not guaranteed.
10. Tidal Volume with PRVC, AutoFlow, VC+, and VS Branson, Respir Care 2005;50:187
14. Adaptive Support Ventilation apnea Over-distention (pressure limit) auto-PEEP rapid-shallow breathing (4.4 mL/kg) Safety Box Determined by IBW -
15. Adaptive Support Ventilation ↓ P, ↑ rate ↓ P, ↓ rate ↑ P, ↑ rate ↑ P, ↓ rate Correct IBW setting important May overshoot tidal volume Role in complicated cases?
16. Proportional Assist Ventilation: Positive Feedback Control P = V/C + V R . ( proportion of assist adjustable) respiratory drive end-inspiratory and expiratory pause maneuvers of 300 ms every 4 to 10 s to estimate of R and C With neuromuscular disease, drive may not translate into flow
17. P AW = V E + V R . Support adjusted to normalize WoB . WoB = ∫ P × Vdt
30. The Evidence for New Ventilator Modes … It’s not the ventilator mode that makes a difference … … It’s the skills of the clinician that makes the difference. Any ventilator mode has the potential to do harm! High level evidence is lacking that any new ventilator mode improves patient outcomes compared to existing lung-protective ventilation strategies.
