Acute Respiratory FailureIn Heart Failure
It is due to:
•Hypoxemia (intrapulmonary shunt)•Increased work of breathing•Augmented O2 consumption•and ultimately leads to muscle fatigue
IEMCC Istanbul 2013Dr A. Khoury 7
• Reduced work of breathing from improved pulmonary compliance
• Increased cardiac output from reduced pre-load and after-load
• Reduced mitral regurgitation
• Unloads the respiratory muscles

There were important methodological limitations in many of the trials, such as lack of blinding and inclusion of only a proportion of patients who presented with ACPE, which restricts the generalizability of these results to all patients with ACPE.
It remains to be determined in the current era of ACPE therapy whether CPAP or NIV confer a mortality benefit. At this time we cannot conclude that NIV offers any advantages over CPAP.

• The internal volume of the masks had no apparent short-term:
• dead space effect on gas exchange• minute ventilation • patient’s effort
• So with the exception of mouthpiece, interfaces may be interchangeable provided adjustment of the ventilatory device parameters are performed.
