💬In plain words
What the trial is, and whether it could suit you
This randomized clinical trial studies how well non-invasive ventilation works in reducing the need for intubation, or placement of a tube in the windpipe, in patients with cancer and respiratory failure. Respiratory failure is a condition in which not enough oxygen passes from the lungs to the blood, and is a common cause of admission to the emergency room in patients with hematological and solid tumor patients. Non-invasive positive pressure ventilation (NIPPV) is a method of delivering oxygen using a mask. It is not yet known whether NIPPV is better at improving the amount of oxygen in the blood, reducing shortness of breath, and the need for intubation than standard high flow oxygen (a tube with 2 prongs placed in the nostrils) in patients with cancer and respiratory failure.

📋 Eligibility rules (as published)
Inclusion Criteria:
* Partial pressure of arterial oxygen (PaO2):fraction of inspired oxygen (FiO2) ratio =\< 300 mmHg OR a peripheral capillary oxygen saturation (SaO2):FiO2 =\< 357
* Have a diagnosed malignancy
* Chest radiograph or computed tomography (CT) scan within =\< 3 months prior to study enrollment rules out primary or metastatic malignancy in the lungs or pleural space as a significant cause of respiratory insufficiency
* Probability of survival is at least 6 months
Exclusion Criteria:
* Presence of do not resuscitate (DNR)/do not intubate (DNI) orders at study entry
* Clinical evidence of left heart failure as the main etiology for respiratory compromise
* Evidence of active intrathoracic malignancy (primary or metastatic) in the lungs or pleural space that is a significant cause of respiratory insufficiency
* Patients with acute chronic obstructive disease exacerbation as the primary etiology for respiratory failure
* Evidence of accessory respiratory muscle use with breathing
* Shock (need for vasopressor therapy or mean arterial pressure \[MAP\] \< 60 despite fluid administration)
* Oliguric acute renal failure (urine output \< 500 ml/day) unless already on hemodialysis
* Patient already on NIPPV at the time of screening
* pH \< 7.30 or partial pressure of carbon dioxide (pCO2) \> 50 (if available)
* Fixed upper airway obstruction
* Airway or facial trauma that would hinder the use of a NIPPV mask
* Uncontrolled tachy or bradyarrhythmia or active myocardial ischemia defined as either: atrial fibrillation with rapid ventricular response (heart rate \[HR\] \> 120 beats per minute \[bpm\]), ventricular tachycardia or nonsustained ventricular tachycardia (any rate), supraventricular tachycardia (any rate), third degree heart block (any rate), heart rate less than 40 beats per minute (regardless of the rhythm)
* Active myocardial ischemia defined as a clinical presentation at the time of screening consistent with acute coronary syndrome which includes unstable angina and electrocardiogram (EKG) changes suggestive of an either an acute ST elevation myocardial infarction (new ST elevations or new left bundle branch block) or acute non-ST elevation myocardial infarction (new ST depressions, new T wave inversions)
* Glasgow Coma Scale (GCS) \< 8 or inadequate airway protective reflexes
