Acute Cardiogenic Pulmonary Oedema • Acute pulmonary edema represents nearly 20% of acute heart failure cases. • The diagnostic criteria of this syndrome have not been universally established. • Sudden onset of severe dyspnoea /the presence of typical signs on physical examination /alveolar oedema on chest radiograph / and acute respiratory failure • Common - 15-20,000 hospital admissions per annum in UK • Deadly - 15-20% in-hospital mortality • Costly - 6.5 million hospital days per annum in USA Eur Heart J. 2008;29:2388-442

When to start NIV in CPE • Patients with pH <7.25 or • systolic blood pressure less than 180 mmHg associated with hypercapnia should be promptly considered for NIV. With this strategy about 40% of the patients would be initially treated with this technique, which would involve nearly 90% of the patients that require intubation. Masip J, et al. Riskfactorsforintubationas a guidefornoninvasiveventilationinpatientswithsevereacutecardiogenicpulmonaryedema. IntensiveCareMed 2003;29:1921-1928
NIV failure in CPE: decide early • Worsening encephalopathy/agitation • Inability to clear secretion • Inability to accept any interface • Hemodynamic instability • Worsening oxygenation • Progressive respiratory acidosis (pH<7.2) • Persistent tachypnea-tachycardia

3-CPO In patients with acute cardiogenic pulmonary oedema, non-invasive ventilation: • Produces more rapid resolution of metabolic abnormalities and respiratory distress • Has no major effect on 7-day or 30-day mortality • Is beneficial irrespective of the mode (CPAP or NIPPV) of delivery Gray et al NEJM 2008; 359:142-51

Early vs late CPAP in the out-of-hospital environment • Conclusion:When compared to usual medical care, immediate application of CPAP alone in out-of-hospital treatment of ACPO is significantly better improving physiological variables and symptoms and significantly reduces tracheal intubation incidence and in-hospital mortality.

Πνευμονικό οίδημα και NIV • To οξύ πνευμονικό οίδημα αποτελεί προνομιακό πεδίο εφαρμογής του ΝΙV • Τόσο η CPAP όσο και ο NIPPV μειώνουν στον ίδιο βαθμό την ανάγκη για διασωλήνωση και βελτιώνουν τη δύσπνοια και τις φυσιολογικές παραμέτρους • Ο ΝΙV δεν φαίνεται να επηρεάζει τη θνητότητα
Πνευμονικό οίδημα και NIV • Αποτελεσματικότερος στους ασθενείς με υπερκαπνία- Ο NIPPV δεν φαίνεται να υπερτερείτης CPAP • Δεν φαίνεται να σχετίζεται με επιπλοκές όπως το OEM • H προνοσοκομειακή χρήση του συνδυάζεται με θετικά αποτελέσματα.
