Non-invasive positive pressure ventilation (NIV) has been shown to be safe and effective as first line treatment in patients with acute hypercapnic respiratory failure and acute cardiogenic pulmonary oedema. Despite some data suggest NIV may also avoid intubation in heterogeneous categories of patients with hypoxemic acute respiratory failure (HARF), its safety and efficacy in such a context is still debated, given the high failure rate and the possible detrimental effect on the clinical outcome.
As patients’ comfort is crucial for NIV success, over the last years a great effort has been made to optimize NIV tolerability. Different interfaces are available for noninvasive ventilation: in spite of face masks being more commonly used, helmet has been shown to improve patients’ comfort, allowing patients’ interaction, speech, feeding and not limiting cough. Nonetheless, skin necrosis, gastric distension, or eye irritation are seldom observed during helmet NIV, while may be consequences of long-term treatments with face masks.
Moreover, differently from face masks, helmets permit longer-term treatments and allow the setting of higher levels of PEEP without causing air leaks or patient-ventilator asynchrony; this aspect may be crucial when treating severely hypoxemic patients with acute respiratory failure and the acute respiratory distress syndrome (ARDS). Interestingly, higher PEEP during fully controlled mechanical ventilation in the early phase of the disease improves mortality in ARDS patients and raising evidence indicates that it may exert beneficial effects also if spontaneous breathing is maintained. In this sense, a recent randomized controlled trial comparing continuous NIV delivered with helmet or face-mask in patients with ARDS showed a lower intubation rate and a lower 90-day mortality in patients in the helmet group who, accordingly, underwent treatments with higher PEEP and lower FiO2. In this study, however, pressure support NIV and low-flow-continuous positive airway pressure (CPAP) were indifferently used in patients randomized to helmet group, despite their mechanisms of action, efficacy and potential harmful effects are profoundly different, especially given the high relevance of the driving pressure in such a context.
No study has ever clarified whether first-line treatment with helmet NIV as compared to other interfaces or techniques may yield a significant benefit to critically ill patients with respiratory failure. In order to establish whether the application of NIV in hypoxemic patients through the helmet might be beneficial without arm in comparison to other interfaces further randomized controlled studies are needed
