Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
both treatment groups(1and 2) received the standard medical treatment in addition to NIV .The NIV were delivered through a full-face mask by a Respironics Synchrony ventilator (Model RTX Inodes, 10 Downage RespiCare, Drager, London). In the CPAP group(group1) a continuous pressure of 10 cmH2O was generated. Patients in Bi-PAP group(group 2) received IPAP (15 cmH2O) and EPAP (5 cmH2O)
. All patients received their assigned treatment for 1 hour. After NIV mask remove the patients continued to receive standardO2 face mask.

Criteria for termination of noninvasive ventilation therapy include inability to tolerate the tightness of the mask or pressure, abundant secretion or met the criteria for intubation according to Brochard et al. 1995. In those who were unable to tolerate the NIV, it was stopped and standard face mask O2 applied.After study period(90 minutes), the patients were transferred to medical ward or admitted to an intensive care unit(ICU) if they require intubation or did not improve.

Treatment: Devices
Comparator / control treatment
Patients were helped to assume a semi-recumbent position. patients of control group ( group 3 ) received the standard medical treatment only , according to the emergency department protocol, at the National Heart Institute. These included:1)supplementary oxygen therapy was supplied at a rate of up to 15 liters per minute via a reservoir mask to maintain oxygen saturation greater than or equal to90%; 2), nitroglycerine 0.4 mg sublingual if systolic BPgreater than100 mmHg-excluding patients receiving potential drug interaction preparations, doses can be repeated every 5 minutes;3) frusemide IV starts with 40 mg and in incremental doses if required; 4)morphine sulfate 2 mg IV, may be repeated once. If BP less than 100mmHg dopamine is given starting at 2.5 mcg/Kg/min intravenous and increase dose every 10 minutes if BP remains low .

Inclusion criteria were: severe dyspnea, bilateral rales on auscultation, and typical findings of congestion on chest radiography without evidence of pulmonary aspiration or pneumonia. In addition, respiratory rate of geater than or equal to 30 breaths per minute, hypoxemia (PaO2 less than80mmHg) with a fraction of inspired oxygen (Fio2) of 60% via a Venturi mask, and PaCO2 less than or equal to 45mmHg[ Nouira et.al 2011 and Ferrari et.al 2009].

Can healthy volunteers participate?
No
Key exclusion criteria
The patients were excluded from this study if they required a lifesaving or emergency intervention, such as primary percutaneous coronary intervention, or if they had chronic obstructive pulmonary diseases, hemodynamic instability (systolic BP less than or equal to 90mmHg), or life threatening arrthymia, acute myocardial infarction and/ or unstable angina, recent facial trauma, and esophageal/gastric surgery, gastrointestinal bleeding, or pregnant [Ferrari et.al 2007and Bellone et.al 2005].

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization was performed using an opaque envelope, which was then further concealed within another. Once enrolled within the study it was impossible to mask treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation). .

Efficacy
Statistical methods / analysis
Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 21.0. Continuous variables were presented as mean and standard deviation while categorical variables were described by frequency and percentage. A one way repeated measure analysis of variance (ANOVA), with the Scheffe test for repeated comparison was used to identify specific differences within and between groups at each time point.Variables without normal distribution and homogeneous variance were analyzed with the Kruskal-Wallis test. All statistical analysis was two-tailed with statistical significant differences was assumed at p =0.05.
The sample size was estimated to be 60 patients in all groups and would be increased to 69 for possible dropout. This sample size was estimated to detect 5terro (0.7PKa) difference in PaCO2 between groups, with the probability level was set at 0.05 and power of 80% [Mehta et al. 1997
