Another factor that decided the balance in favor of NIMV was the extraordinary clinical tolerance of hypoxemia shown by these patients – this indicating dichotomization between the clinical picture and the blood gas and radiological findings. Despite the severe hypoxemia produced by the diffuse infiltrates in several lung fields, the patients showed clinical tolerance of the condition far greater than that seen in patients with the same degree of hypoxemia but produced by pneumonia or ARDS, since subjects with processes of this kind tend to suffer markedly labored breathing.</p><p id="par0150" class="elsevierStylePara elsevierViewall">Finally, the absence of evident signs of muscle fatigue led us to use continuous positive airway pressure (CPAP) systems instead of noninvasive devices with two pressure levels (except in 2 cases). Through the production of supra-atmospheric pressure along the respiratory cycle, the CPAP systems increase residual functional capacity and displace the fluid filling the alveoli towards the periphery, thereby increasing the surface for gas exchange – which in turn results in a reduction of the hypoxemia. Although CPAP is not in truth a NIMV system, it is usually viewed as such because it offers most of the properties of NIMV.</p><p id="par0155" class="elsevierStylePara elsevierViewall">The use of NIMV as first therapeutic option is in contraposition to the literature,<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1,2,10–12</span></a> where the percentage of patients ventilated with NIMV is relatively small (6–33%), and involves a failure rate of over 85%.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> This disparity of results may be due to the greater number of failed organs in these patients at the start of NIMV, in contrast to the situation of almost exclusive respiratory failure found in our patients at the time of starting noninvasive support (measured with the SOFA scale), together with the fact that they were referred directly from the Emergency Department, with immediate initiation of NIMV.</p><p id="par0160" class="elsevierStylePara elsevierViewall">Although some articles have reported satisfactory results with NIMV in hypoxemic patients,<a class="elsevierStyleCrossRefs" href="#bib0020"><span class="elsevierStyleSup">4–6</span></a> and even in patients with ARDS, the poor results obtained as a consequence of experience gained with NIMV in both Canada<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> and the United States have generated skepticism towards the use of NIMV, and this is presently reflected in the recommendations relating to ventilatory support.<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">13</span></a> The other factor influencing the rejection of NIMV is the added risk of viral spread through the microdroplets and contagion of the healthcare personnel,<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">13</span></a> as occurred in the 2003 epidemic registered in Canada, where 72% of the healthcare personnel members became infected.

Taking into consideration that prolonged ventilation was expected in hypoxemic patients, and the fact that there were no evident signs of labored breathing or hypercapnia, we decided to use these devices, which moreover were found to be effective. The main inconvenience of the helmet system using CPAP is carbon dioxide retention,<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> though this problem was not observed in any of our patients, since high air-oxygen flows were used.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> On the other hand, the complications rate was low – the main problem being the noise produced by the CPAP continuous flow system.</p><p id="par0170" class="elsevierStylePara elsevierViewall">Is NIMV a panacea?

This is an issue for debate.</p><p id="par0175" class="elsevierStylePara elsevierViewall">In what patients would we consider noninvasive support from the start? Perhaps in conscious and cooperative patients, without situations of shock and with almost exclusive respiratory failure, without evident signs of labored breathing (which may require immediate orotracheal intubation) or presenting metabolic lactic acidosis which would be indicative of tissue hypoperfusion. The time we should wait before considering intubation in a patient failing to show clear blood gas improvements has not been clearly established, though a delay in intubation has been shown to increase mortality.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">18</span></a> As predictive factors of NIMV failure, Antonelli et al.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">6</span></a> established the presence of increased patient severity (SAPS II<span class="elsevierStyleHsp" style=""></span>><span class="elsevierStyleHsp" style=""></span>34) and the absence of improvement of the pO<span class="elsevierStyleInf">2</span>/FiO<span class="elsevierStyleInf">2</span> ratio to >175 1<span class="elsevierStyleHsp" style=""></span>h after starting NIMV.
