2 Acute Cardiogenic Pulmonary Oedema
Common ,000 hospital admissions per annum in UK Deadly % in-hospital mortality Costly million hospital days per annum in USA 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 Eur Heart J. 2008;29:

12 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. Risk factors for intubation as a guide for noninvasive ventilation in patients with severe acute cardiogenic pulmonary edema. Intensive Care Med 2003;29:

13 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

35 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.

37 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

38 Πνευμονικό οίδημα και NIV
Αποτελεσματικότερος στους ασθενείς με υπερκαπνία- Ο NIPPV δεν φαίνεται να υπερτερεί της CPAP Δεν φαίνεται να σχετίζεται με επιπλοκές όπως το OEM H προνοσοκομειακή χρήση του συνδυάζεται με θετικά αποτελέσματα.
