Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Continuous postive airway pressure (CPAP) at 10 cm H20 with face mask will be used for patients in acute respiratory distress with clnical diagnosis of acute cardiogenic pulmonary oedema) ACPO. The duration of the treatment will be time transported and treated by paramedics. All other treatments will be cosistant between groups (Glycerine trinitrate (GTN) spray incremental doses every 5 min of 400 mcg up to 1600 mcg sublingual with repreated 1600 mcg every 5 min as long as BP >100 systolic, Frusemide dose 40 mg increments every 20 min to max 80 mg intravenous)

Treatment: Devices
Comparator / control treatment
inspired positive pressure ventilation (IPPV) with bag valve mask will be used for patients in acute respiratory distress with clnical diagnosis of acute cardiogenic pulmonary oedema) ACPO. The duration of the treatment will be time transported and treated by paramedics. All other treatments will be cosistant between groups (GTN, Frusemide)
