Brief Summary:
This study objectively held to compare the physiological outcomes in the non-invasive (NIV) treatment of Acute Cardiogenic Pulmonary Oedema (ACPE) patients in the Emergency Department (ED) delivered by Helmet CPAP (hCPAP) and HFNC.Patients will be randomized to receive either hCPAP or HFNC.

Condition or disease Intervention/treatment Phase
Cardiogenic Pulmonary Edema Device: hCPAP versus HFNC Not Applicable

Detailed Description:

Non-invasive ventilation(NIV) has different types of interfaces that had been used in acute hypoxaemic and hypercapnic respiratory failure. The appropriate interface is necessary to provide comfort and lead to the success of NIV.

Helmet continuous positive airway pressure (hCPAP) is an NIV interface that allows the provision of high airway pressures with a minimal leak.

HFNC which delivers heated humidified high flow oxygen provides a good alternative to the conventional NIV in terms of comfort

Arm Intervention/treatment
Active Comparator: Helmet Continuous Positive Airway Pressure(hCPAP)
Helmet CPAP produce a better physiological outcomes after 1-hour intervention
Device: hCPAP versus HFNC
The patient presented with Acute Cardiogenic Pulmonary Edema will be randomized into either helmet CPAP or HFNC.

Active Comparator: High Flow Nasal Cannula(HFNC)
HFNC produce a better physiological outcomes after 1-hour intervention
Device: hCPAP versus HFNC
The patient presented with Acute Cardiogenic Pulmonary Edema will be randomized into either helmet CPAP or HFNC.

Primary Outcome Measures :
  1. Respiratory Rate [ Time Frame: 1 hour ]
    Respiratory rate reduction post intervention

Secondary Outcome Measures :
  1. Heart Rate [ Time Frame: 1 hour ]
    Heart rate reduction post intervention

  2. Partial Pressure Of Arterial Oxygen Level [ Time Frame: 1 hour ]
    Partial arterial oxygen level post intervention

  3. Ratio Of Partial Pressure Arterial Oxygen And Fraction Of Oxygen [ Time Frame: 1 hour ]
    Partial arterial oxygen/fraction of oxygen ratio improvement post intervention

  4. Dyspnoea Scale [ Time Frame: 1 hour ]
    Dyspnoea scale improvement post intervention.Dyspnea scale measured using an unmarked 10cm VAS card that had mark with "I can breathe normally", at one end correspond to patients' normal baseline breathing which score "0" and on the other end "I can't breathe at all", which score "10" represent the worst difficulty perceived by patients.

  5. Heart Rate,Acidosis (pH), Consciousness (GCS), Oxygenation (PF ratio) And Respiratory Rate(HACOR) Score [ Time Frame: 1 hour ]
    Heart rate,Acidosis (pH), Consciousness (GCS), Oxygenation (PF ratio) and Respiratory rate(HACOR) Score improvement post intervention.HACOR is an acronym for heart rate, acidosis (pH), consciousness (GCS), oxygenation (PF ratio) and respiratory rate in which each parameter is an independent predictor for NIV failure. HACOR score is out of 25 with differential weighting of each parameter.

  6. Rate Of Intubation [ Time Frame: 1 hour ]
    Intubation rate post intervention

  7. 28-Days Mortality In Acute Cardiogenic Pulmonary Edema [ Time Frame: 28 days ]
    Mortality due to Acute Cardiogenic Pulmonary Edema
