Conditions
Interventions
Participants are allocated to groups based on their type of acute respiratory failure:

Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| 1. Days of hospitalisation is measured using patient records at number of discharge 2. Number of endotrachael intubation is measured using patient records at number of intubated patients and their percentage at discharge 3. Death is measured using patient records at time of death | — |
Primary
| Measure | Time frame |
|---|---|
| 1. Use of NIV is measured using patient records at discharge from hospital 2. Aterial blood gas is measured using an arterial blood gas test (blood test) at baseline, one, 12 and 24 hours of NIV use 3. Severity of disease is measured using the APACHE II (Acute Physiology and Chronic Health Evaluation (APACHE II ) score at range (0-71 points) 4. Blood pressure (mm/Hg) is measured using a blood pressure cuff 5. Heart rate is measured using pulse monitors 6. Respiratory rate is measured using the amount of breaths over one minute. 7. Tidal volume (mL) programmed AVAPs is measured using patient records. 8. Levels of IPAP (cmH2O) are measured using patient records 9. Level of EPAP (cmH2O) are measured using patient records 10. Inspiratory time (mseg) is measured using patient records 11. Tidal volume patients (mL) is measured using patient records 12. Radiographic changes are measured at number quadrant divided into four according to the affection 13. Complications (excessive discomfort, nasal ulcer, gastric distension and claustrophobia) are measured using patient records | — |
