First&#44; it is possible that ventilation strategies have changed over recent years&#46; Lower tidal volumes are increasingly used&#44; and V<span class="elsevierStyleInf">T</span> reduction can result in lower oxygen levels&#44;

Third&#44; hyperoxemia could be more difficult to achieve in patients with COVID&#8211;19 ARDS&#44; due to extensive pulmonary infiltrates or sometimes the presence of pulmonary embolism&#46;</p><p id="para0037" class="elsevierStylePara elsevierViewall">One important finding of our study is that outcomes were not different between hyperoxemic versus normoxemic patients&#46; However&#44; this may not be too surprising since the differences in oxygen levels between the two patient groups were not as large as in the initial investigations that studied the effects of hyperoxemia in critically ill patients&#8211;&#8211;of note&#44; this was also the case in the recent randomized clinical trials that all showed no benefit of a low oxygen versus a high oxygen strategy&#46;<a class="elsevierStyleCrossRefs" href="#bib0008"><span class="elsevierStyleSup">8-11</span></a> However&#44;

PEEP&#44; however&#44; was consistently higher in the hyperoxemic patients&#44; even after matching&#46; This may not be unexpected&#44; as higher PEEP can result in more lung recruitment and thus improve oxygenation&#44; as for instance also seen in patients in one study that was performed before just before the COVID&#8211;19 pandemic&#46;<a class="elsevierStyleCrossRef" href="#bib0032"><span class="elsevierStyleSup">32</span></a> Alike in patients with ARDS due to another cause&#44; PEEP can also reaerate consolidated regions of the lungs in COVID&#8211;19 patients&#44;<a class="elsevierStyleCrossRef" href="#bib0033"><span class="elsevierStyleSup">33</span></a> thereby improving oxygenation&#46;<a class="elsevierStyleCrossRef" href="#bib0034"><span class="elsevierStyleSup">34</span></a> However&#44; we do not suggest that high PEEP should be applied in all COVID&#8211;19 patients to improve oxygenation&#44; as improved oxygenation does not automatically result in better outcome and non&#8211;recruitable patients are at high risk of overdistension and hemodynamic impairment&#46;<a class="elsevierStyleCrossRef" href="#bib0032"><span class="elsevierStyleSup">32</span></a> Interestingly&#44;

However&#44; only 13&#46;6&#37; of all the observed time&#8211;points showed excessive use of oxygen&#44; which at least suggests that clinicians responded adequately to hyperoxemia with a reduction in FiO<span class="elsevierStyleInf">2</span>&#46;

the LOESS curve demonstrated increasing mortality with increasing levels of FiO<span class="elsevierStyleInf">2</span> regardless of the presence of hyperoxemia&#44; and although this is partially linked to severity of disease&#44; it could also represent the deleterious effects that high levels of FiO<span class="elsevierStyleInf">2</span> can have on lung tissue&#46;<a class="elsevierStyleCrossRef" href="#bib0036"><span class="elsevierStyleSup">36</span></a></p><p id="para0040" class="elsevierStylePara elsevierViewall">Limitations of this analysis are as follows&#46; We restricted the analysis to the first two days of oxygenation&#44; and therefore cannot be sure whether dysoxemia at later time points had detrimental effects&#46; The definitions of hyperoxemia and excessive oxygen were arbitrary&#44; as there are no definitive targets for PaO<span class="elsevierStyleInf">2</span> or FiO<span class="elsevierStyleInf">2</span>&#46; Higher cut-offs for PaO<span class="elsevierStyleInf">2</span> and FiO<span class="elsevierStyleInf">2</span> could have resulted in other prevalences of hyperoxemia and excessive oxygen use&#44; and maybe even associations of dysoxemia with outcome&#46; Due to the low number of hypoxemic patients in this cohort&#44; we were not able to compare outcomes in these patients&#46; However&#44; the sensitivity analysis in which we excluded hypoxemic patients showed that there were no differences in clinical outcomes&#46; We were not able to collect data to gain insight in oxygen management per se&#44; and we did also not collect the protocols in place at the participating centres&#46; Unfortunately&#44; we did not acquire ventilation data before intubation and therefore were not able to calculate the ROX index in patients previously on high flow nasal oxygen &#40;HFNO&#41;&#46; This index &#40;ratio of SpO<span class="elsevierStyleInf">2</span>&#47;FiO<span class="elsevierStyleInf">2</span> to respiratory rate &#40;RR&#41;&#41; predicts whether patients on HFNO will be in need of intubation&#44; and it would have been interesting to see whether hyperoxemic patients had a lower chance of HFNO failure based on the ROX index&#46;</p></span><span id="sec0017" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cesectitle0023">Conclusions</span><p id="para0041" class="elsevierStylePara elsevierViewall">In this cohort of COVID&#8211;19 ARDS patients&#44;
