Brief Summary

Non-invasive ventilation (NIV) has become now a widely used treatment modality in ICU and emergency services to deal with respiratory failure.1 NIV has the potential to improve ventilatory assistance while avoiding endotracheal intubation and its complications. Since the first publications of Meduri2 and Brochard3 the number of studies on the NIV has been growing and developing and this technique becomes one of the major progress in the field of respiratory assistance. Decompensation of chronic obstructive pulmonary disease (COPD) is certainly the least questionable indication of the NIV. However, indication of the NIV is inexorably spreading to other types of acute respiratory insufficiency, including acute cardiogenic pulmonary edema (CPE).4 Continuous positive airway pressure (CPAP) is the most currently used non-invasive ventilation usually performed without the use of a ventilator. NIV using pressure support (NIPSV) combined pressure support (inspiratory aid) and positive expiratory pressure as in CPAP. Based on physiological ground, NIPSV would be more performant than CPAP to improve ventilatory parameters and reduce the work breathing in APE. However, this issue is not settled yet. Number of meta-analysis over the last 2 years were devoted to the comparison of CPAP and NISPV,5 so that the scientific evidence is still far from established. In addition, it is not sur that patients enrolled in these studies are representative of all patients with APE. The fact that they were included solely on the basis of clinical criteria, the risk of overlap with other diagnoses is not negligible. Thus the use of markers of heart failure as the BNP (brain natriuretic peptide) would be very useful. On the other hand, the possible deleterious effect of NIPSV on myocardial perfusion is a problem that has not been definitively resolved. Objectives of the study:

  1. 1.Compare the efficacy and safety of the NIPSV with those of CPAP in patients presenting to the emergency department with CPE.
  2. 2.Compare the two procedures in subgroups of patients with hypercapnia and high BNP concentration.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • All patients aged \>18 years and having acute respiratory failure caused by CPE.
  • The origin of cardiogenic pulmonary edema is defined according to the history and clinical presentation, the chest X-ray and / or data of echocardiography when they are available with a serum BNP\> 100pg/ml.
  • The acute respiratory failure is defined by the existence of clinical signs and / or arterial gas parameters:
  • sweats and / or agitation and / or signs of struggle and /or drowsiness
  • dyspnea with respiratory rate \> 35/min,
  • a blood oxygen saturation ≤ 90% by air.

You may not qualify if:

  • Instability of the hemodynamic state (severe rhythm disturbances, hypotension with systolic arterial pressure \<50 mmHg, need for inotropic drugs).
  • The need for immediate endotracheal intubation.
  • Contraindications to the use of a facial or nasal mask (or facial skin lesion).
  • History of recent gastrointestinal surgery or pseudo obstruction.
  • Refusal of participation or non-cooperation of the patient.
