Non-invasive ventilation (NIV) refers to the technique of providing mechanical ventilation that does not require definitive airway clearance using an endotracheal tube or tracheostomy. Since its early development in the 1980s, the use of NIV has become increasingly popular in the last three decades. However, its usage on COVID-19 related respiratory failure still lacked guidelines, although several recent studies have shown its benefits. Many aspects, ranging from indications or patient selection, timing to start, understanding the predictor factors of failure, and choosing suitable interfaces, are keys of success for NIV. In principle, each patient has a different condition and should be treated case by case. NIV is not an absolute solution, and intubation can still be the first choice if NIV is deemed less beneficial for the patient.

BACKGROUND Community-Acquired Pneumonia (CAP) is defined as “an acute infection of the pulmonary parenchyma. The most important complication of CAP is Acute Respiratory Failure (ARF) and some of them may require Invasive Mechanical Ventilation (IMV) to manage hypoxia and hypoventilation along with appropriate antibiotic therapy. A number of studies, however, indicate that IMV is associated with high rates of serious complications and mortality in patients with ARF. For this reason Non-Invasive Ventilation (NIV) has been used for ARF of diverse aetiologies.The most important rationale for using NIV in early stages of respiratory failure is to decrease the workload on respiratory muscles and improve ventilation by applying positive airway pressure. This may help to overcome an episode of severe ARF without the need for MV. In this study we evaluated the efficacy of NIV in patients with ARF and compare the outcome of using NIV in CAP with ARF patients with and without comorbidities. METHODS This prospective observational study was done on 150 CAP patients in acute respiratory failure who received NIV. It was conducted in the Department of Respiratory Medicine in Gandhi Hospital, Secunderabad, for a period of one year and six months. A comparative analysis of the outcome of using NIV in CAP with ARF patients with and without co-morbidities was carried out. RESULTS In the current study 150 CAP patients with ARF who needed NIV, were treated initially with NIV, antibiotic therapy and other supportive measures as per the American Thoracic Society (ATS) guidelines 32. 95 (63.3 %) of 150 patients were continuously treated with NIV. Apart from these, 55 (36.7 %) patients required MV. In patients with continued NIV, 93 (98 %) recovered, remaining 2 died with sudden cardiac arrest. In patients who were gone for MV, 12 (22 %) survived. CONCLUSIONS Early intervention by NIV in CAP patients suffering from acute respiratory failure secondary to community acquired pneumonia was found to be successful in avoiding mechanical ventilation and its attendant morbidity and mortality31. Early intervention with NIV, identifying risk factors for NIV failure, addressing associated co-morbid conditions will go in a long way in effectively managing these patients by significantly minimizing the ICU and hospital stay. Patients with co-morbidities have more chances of NIV failures. Patients with co morbidities on NIV stayed significantly more number of days in the hospital than patients without co-morbidities. The current study suggests that co morbid patients require more monitoring as compared to patients without co morbidities on NIV.

Background: Despite the increasing use of high flow nasal cannula oxygenation systems (HFNC) in clinical practice, little is known about its role in all cause respiratory failure as compared to traditional non-invasive ventilation (BiPAP). Furthermore, the effect of HFNC on mortality is unknown. Methods: We conducted a retrospective analysis of 49,853 patients with respiratory failure treated with non-invasive respiratory support (HFNC or BiPAP) and/or invasive mechanical ventilation (IMV) between 2017 and 2018. Results: Patients initially treated with HFNC who underwent subsequent intubation and IMV had a higher mortality rate as compared to patients who were initially treated with BiPAP and underwent subsequent intubation and IMV (34.8% vs 26.3%, p < 0.0001, OR 1.49, 95% CI 1.26,1.76). Patients first treated with HFNC who underwent subsequent intubation and IMV had a significantly increased mortality compared to patients who underwent immediate intubation and IMV (34.8% vs. 21.5%, p ≤ 0.0001, OR 1.94, 95% CI 1.67, 2.27). Stratified based on ICD-10 diagnosis, patients with a diagnosis of COPD exacerbation or heart failure treated with HFNC and subsequent intubation and IMV had higher mortality as compared to those treated with immediate IMV alone. This trend did not hold true for patients with a diagnosis of pneumonia. Conclusion: In a real-world retrospective analysis, use of HFNC was associated with increased mortality as compared to BiPAP and IMV alone. Further study is needed to confirm these associations.

Adequate Oxygenation

Critically ill patients admitted to hospital following SARS-CoV-2 infection often experience hypoxic respiratory failure and a proportion require invasive mechanical ventilation to maintain adequate oxygenation. The combination of prone positioning and non-invasive ventilation in conscious patients may have a role in improving oxygenation. The purpose of this study was to assess the effect of prone positioning in spontaneously ventilating patients receiving non-invasive ventilation admitted to the intensive care.  Clinical data of 81 patients admitted with COVID 19 pneumonia and acute hypoxic respiratory failure were retrieved from electronic medical records and examined. Patients who had received prone positioning in combination with non-invasive ventilation were identified. A total of 20 patients received prone positioning in conjunction with non-invasive ventilation. This resulted in improved oxygenation as measured by a change in PaO2/FiO2 (P/F) ratio of 28.7 mmHg while prone, without significant change in heart rate or respiratory rate. Patients on average underwent 5 cycles with a median duration of 3 hours. There were no reported deaths, 7 of the 20 patients (35%) failed non-invasive ventilation and subsequently required intubation and mechanical ventilation. In our cohort of 20 COVID-19 patients with moderate acute hypoxic respiratory failure, prone positioning with non-invasive ventilation resulted in improved oxygenation. Prone positioning with non-invasive ventilation may be considered as an early therapeutic intervention in COVID-19 patients with moderate acute hypoxic respiratory failure.

Abstract Background The most common cause of respiratory failure in premature infants is respiratory distress syndrome. Historically, respiratory distress syndrome has been treated by intratracheal surfactant injection followed by mechanical ventilation. In view of the risk of pulmonary injury associated with mechanical ventilation and subsequent chronic pulmonary lung disease, less invasive treatment modalities have been suggested to reduce pulmonary complications. Methods 148 neonates (with gestational age of 28 to 34 weeks) with respiratory distress syndrome admitted to Imam Khomeini Hospital in Ahwaz in 2018 were enrolled in this clinical trial study. 74 neonates were assigned to duo positive airway pressure (NDUOPAP) group and 74 neonates to nasal continuous positive airway pressure (NCPAP) group. The primary outcome in this study was failure of N-DUOPAP and NCPAP treatments within the first 72 h after birth and secondary outcomes included treatment complications. Results there was not significant difference between DUOPAP (4.1 %) and NCPAP (8.1 %) in treatment failure at the first 72 h of birth (p = 0.494), but non-invasive ventilation time was less in the DUOPAP group (p = 0.004). There were not significant differences in the frequency of patent ductus arteriosus (PDA), pneumothorax, intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD), apnea and mortality between the two groups. Need for repeated doses of surfactant (p = 0.042) in the NDUOPAP group was significantly lower than that of the NCPAP group. The duration of oxygen therapy in the NDUOPAP group was significantly lower than that of the NCPAP group (p = 0.034). Also, the duration of hospitalization in the NDUOPAP group was shorter than that of the NCPAP group (p = 0.002). Conclusions In the present study, DUOPAP compared to NCPAP did not reduce the need for mechanical ventilation during the first 72 h of birth, but the duration of non-invasive ventilation and oxygen demand, the need for multiple doses of surfactant and length of stay in the DUOPAP group were less than those in the CPAP group.

IntroductionA palliative approach to intensive care unit (ICU) patients with acute respiratory failure and a do-not-intubate order corresponds to a poorly evaluated target for non-invasive oxygenation treatments. Survival alone should not be the only target; it also matters to avoid discomfort and to restore the patient’s quality of life. We aim to conduct a prospective multicentre observational study to analyse clinical practices and their impact on outcomes of palliative high-flow nasal oxygen therapy (HFOT) and non-invasive ventilation (NIV) in ICU patients with do-not-intubate orders.Methods and analysisThis is an investigator-initiated, multicentre prospective observational cohort study comparing the three following strategies of oxygenation: HFOT alone, NIV alternating with HFOT and NIV alternating with standard oxygen in patients admitted in the ICU for acute respiratory failure with a do-not-intubate order. The primary outcome is the hospital survival within 14 days after ICU admission in patients weaned from NIV and HFOT. The sample size was estimated at a minimum of 330 patients divided into three groups according to the oxygenation strategy applied. The analysis takes into account confounding factors by modelling a propensity score.Ethics and disseminationThe study has been approved by the ethics committee and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals.Trial registration numberNCT03673631
