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
