Preceding studies showed that as much as 20 of individuals want hospital admission [3], with an in-hospital mortality ranging from 16 to 78 [1,two,4,5]. Sufferers with respiratory failure often encounter hypoxemia, elevated respiratory rate and inspiratory effort [6]. Moreover, differently from standard ARDS, the pathophysiology of COVID-19-related ARDS is characterized by different degrees of micro/macro-thrombosis and by regional dysregulation of lung blood flow [7], which contribute for the ventilation-perfusion mismatch and increased shunt fraction [8,9]. Respiratory help ought to decrease the inspiratory effort and also the pulmonary pressure (i.e., patient self-inflicted lung injury) [102]. Based around the severity of acute respiratory failure, the respiratory assistance can contain high flow oxygen therapy, continuous optimistic airway pressure (CPAP), noninvasive (NIV) and invasive mechanical ventilation (IMV) [6]. Early European consensus statements for the management of non-critically ill COVID-19 patients with acute respiratory failure advised Helmet CPAP as 1st option, the mask CPAP as the second choice and NIV applied with face mask as final alternative [3,13,14]. Alternatively, the Italian Society of Anti-Infective Therapy and Italian Respiratory Society suggested that Helmet CPAP needs to be the first line of respiratory assistance with a PEEP titrated not exceeding 12 cm H2 O based on a patient’s demands, tolerability and adverse events [15,16]. Conversely, the Surviving Sepsis Campaign did not make any recommendations regarding the usage of CPAP, offering only a weak recommendation for NIV [17]. The proportion of sufferers treated with noninvasive respiratory supports could differ from 62 in China to 20 and 11 in North America and Italy, respectively [18,19]. Mortality price will not differ in patients initially treated with a noninvasive respiratory assistance and subsequently intubated in comparison with these straight away treated with IMV when admitted to hospital [2]. However, the majority from the studies have been performed in intensive care units and only several data are readily available for patients treated with CPAP and/or NIV outside the intensive care units [196]. Inside the latter case, helmet CPAP is generally prescribed [19,21], having a failure price ranging from 27 to 44 plus a mortality price from 25 to 30 [191,26]. CPAP failure (i.e., persistent serious hypoxemia or high respiratory rate and inspiratory effort) might be followed in selected circumstances by a NIV trial just before implementing IMV [27]. On the other hand, noninvasive respiratory assistance in patients with extremely severe respiratory failure may perhaps favor a delayed intubation, escalating mortality [28]. IMV must be promptly offered within the case of deterioration on the clinical situations [29]. A large Italian retrospective study lately showed that sufferers treated with helmet CPAP or NIV had comparable outcomes [20]; nonetheless, patients failing CPAP have been directly intubated without a NIV trial. The aim with the present study was to retrospectively assess the intubation rate of a noninvasive respiratory approach based mainly around the prescription of helmet CPAP and.
