NON-INVASIVE RESPIRATORY SUPPORT BY OXYGENATION HELMET IN ACUTE RESPIRATORY FAILURE: A SCOPING REVIEW

Abstract

Noninvasive ventilation (NIV) has shown promise in the context of acute respiratory failure, as it inhibits the progression of mild to moderate clinical conditions, sometimes sparing the need for invasive ventilation. One of the prominent interfaces, widely used in the scenario of the covid-19 pandemic, was the helmet device – a helmet made of transparent material that surrounds the patient's head like an air reservoir. Despite its wide use, the medical literature is little explored regarding the advantages and clinical indications for the use of this device. For these reasons, the present scoping review aims to elucidate, based on current clinical-scientific evidence, the main concepts, advantages, and challenges involved in NIV, focusing on the helmet device. According to the guidelines of the Joanna Briggs Institute, the search was carried out in the MEDLINE/PubMed database. After applying the eligibility criteria, supported by the PRISMA methodology, 33 articles were included and independently summarized and contemplated by peers. In this review, it was verified that NIV, through the helmet device, with the possibility of using positive pressure in the airways, is safe and can reduce the need for invasive ventilation, composing an important oxygen therapy option, in addition to being viable for use even outside the intensive care environment. There is still a discussion about which patients would benefit from this device, as well as the appropriate clinical moment to indicate this ventilatory support, demonstrating an important theme to be explored in future clinical trials.
