the practical guide for NIV part 3


Continuous positive airway pressure (CPAP):
  • CPAP is a  fixed positive pressure throughout the respiratory cycle.
  • CPAP appears to be more effective in reducing the need for tracheal intubation and possibly mortality in patients presenting with with acute cardiogenic pulmonary oedema (ACPE).
Bi-level positive airway pressure (BiPAP):
  • BiPAP is when the ventilator delivers different levels of pressure during inspiration (IPAP) and expiration (EPAP).
  • BiPAP ventilation appears to be more effective in reducing mortality and the need for tracheal intubation in patients with an acute decompensation of COPD.

Driving Pressure in ARDS: A new concept!

Driving Pressure and Survival in the Acute Respiratory Distress Syndrome Marcelo B.P. Amato, M.D., Maureen O. Meade, M.D., Arthur S. Slutsky, M.D., Laurent Brochard, M.D., Eduardo L.V. Costa, M.D., David A. Schoenfeld, Ph.D., Thomas E. Stewart, M.D., Matthias Briel, M.D., Daniel Talmor, M.D., M.P.H., Alain Mercat, M.D., Jean-Christophe M. Richard, M.D., Carlos R.R. Carvalho, M.D., and Roy G. Brower, M.D. N Engl J Med 2015; 372:747-755 February 19, 2015 DOI: 10.1056/NEJMsa1410639 BACKGROUND Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (V T ), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress syndrome (ARDS), but the relative importance of each of these components is uncertain. Because respiratory-system compliance (C RS ) is strongly related to the volume of aerated remaining functional lung during disease (termed functional lung size)...
