Continuous Positive Airways Pressure (CPAP) In Left Ventricular Dysfunction Acute Pulmonary Oedema


CPAP General Facts:
  • Continuous positive airways pressure (CPAP).
  • May be useful in the management of acute pulmonary oedema related to left ventricular failure.
  • CPAP has both cardiac and pulmonary benefits.
CPAP Cardiac Benefits:
  • Reduction in left ventricular (LV) preload.
  • Reduction in mitral regurgitation.
  • Improved ejection fraction.
CPAP Pulmonary Benefits:
  • Increases functional residual capacity.
  • Leading to an effective increase in alveolar surface area.
  • Leading to improved oxygenation.
  • Leading to reduced work of breathing.
CPAP Cautions:
  • Hyperinflated chest
  • Restrictive chest wall disease
