Severe bronchial asthma complicated with respiratory failure, a common critical illness in respiratory medicine, may be life-threatening. High-flow nasal cannula (HFNC) is a novel oxygen therapy technique developed in recent years. HFNC was applied in this study for treating adult patients with severe bronchial asthma complicated with respiratory failure. Its efficacy was analyzed comparatively to conventional oxygen therapy (COT). HFNC and COT were randomly performed based on conventional treatment. The HFNC group was similar to COT-treated patients in terms of response rate, with no significant difference in efficacy between the two groups. In patients with bronchial asthma, effectively increased PO2 and reduced PCO2 were observed after treatment in both groups. However, HFNC was more efficient than COT in elevating PO2 in patients with severe bronchial asthma complicated with respiratory failure, while no statistically significant difference in PCO2 reduction was found between the two groups. Heart rate (HR) and respiratory rate (RR) between the two groups on admission (0 h) and at 2, 8, 24, and 48 h after admission were compared. Both indicators significantly decreased with time. No significant differences in HR and RR were found between the groups at 0, 2, and 8 h after admission. However, these indicators were significantly lower in the HFNC group compared with the COT group at 24 and 48 h after admission. HFNC could significantly elevate PO2 and reduce HR and RR. Thus, it is a promising option for patients with severe bronchial asthma complicated with respiratory failure.

Hypoxic Respiratory Failure

The novel corona virus (SARS-CoV-2) continuous to spread around the globe causing high mortality, tremendous stress on healthcare systems and an unprecedented disruption of everyday life with unpredictable socioeconomic ramifications. The diseaseis typically affecting the respiratory system and some patients will develop refractory hypoxemic respiratory insufficiency requiring mechanical ventilation. The role of non-invasive ventilation (NIV), high flow nasal cannula (HFNC) or continuous positive airway pressure devices (C-PAP) in the treatment of the 2019 corona virus disease (COVID-19) is not yet clear. We hereby report a case of a 44-year-old COVID-19 positive male patient suffering from hypoxic respiratory failure that was successfully treated with high flow nasal cannula oxygen therapy in a negative pressure intensive care room. Although specific criteria for the use of high flow nasal canula devices COVID-19 are not available at this time, clinicians could use this non-invasive modality as analternative method of respiratory support in selected patients presenting with respiratory failure.

Conventional oxygen therapy (COT) and noninvasive ventilation (NIV) have been considered for decades as frontline treatment for acute or chronic respiratory failure. However, COT can be insufficient in severe hypoxaemia whereas NIV, although highly effective, is poorly tolerated by patients and its use requires a specific expertise. High-flow nasal cannula (HFNC) is an emerging technique, designed to provide oxygen at high flows with an optimal degree of heat and humidification, which is well tolerated and easy to use in all clinical settings. Physiologically, HFNC reduces the anatomical dead space and improves carbon dioxide wash-out, reduces the work of breathing, and generates a positive end-expiratory pressure and a constant fraction of inspired oxygen. Clinically, HFNC effectively reduces dyspnoea and improves oxygenation in respiratory failure from a variety of aetiologies, thus avoiding escalation to more invasive supports. In recent years it has been adopted to treat de novo hypoxaemic respiratory failure, exacerbation of chronic obstructive pulmonary disease (COPD), postintubation hypoxaemia and used for palliative respiratory care. While the use of HFNC in acute respiratory failure is now routine as an alternative to COT and sometimes NIV, new potential applications in patients with chronic respiratory diseases (e.g. domiciliary treatment of patients with stable COPD), are currently under evaluation and will become a topic of great interest in the coming years.

KEY FINDINGSVery low-quality evidence suggests lower mortality (based on five observational studies) but higher failurerate of respiratory support (based on two observational studies) in COVID-19 patients given high-flow nasalcannula (HFNC) oxygen compared with noninvasive ventilation (NIV) and conventional oxygenation therapy.Randomized controlled trials (RCT) are urgently needed in this area.• Respiratory failure accounts for about half of deaths in patients with COVID-19.• High-flow nasal cannula (HFNC) oxygen therapy reduces the need for escalating respiratory support and improvespatient comfort compared with conventional oxygen therapy among those with acute respiratory failure.• Mortality was consistently lower in COVID-19 patients who received HFNC rather than NIV or conventionaloxygen therapy (COT) across 5 very low-quality retrospective observational studies from China.• Several international guidelines recommend the use of HFNC oxygen therapy in COVID-19 patients whodevelop acute hypoxemic respiratory failure. However, local guidelines from the Philippine Society forMicrobiology and Infectious Diseases (PSMID) and the Philippine College of Chest Physicians (PCCP) recommendagainst HFNC due to risks of transmission and paucity of direct evidence for efficacy.• Additional infection control precautions, i.e. wearing a surgical mask over the cannula, and locating in a negativepressure room, are recommended whenever using HFNC or NIV.• There are at least two ongoing trials due to be completed by the second quarter of 2021 comparingHFNC oxygenation with NIV or COT in COVID-19 patients.

Abstract Objectives: To investigate the indications of high-flow nasal cannula (HFNC) oxygen therapy among patients with mild hypercapnia and to explore the predictors of intubation when HFNC fails.Methods: This retrospective study was conducted based on the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Adult patients with mild hypercapnia (45<PaCO2≤60 mmHg) received either HFNC or noninvasive ventilation (NIV) oxygen therapy. Propensity score matching (PSM) was implemented to increase between-group comparability. The Kaplan-Meier method was used to estimate overall survival and cumulative intubation rates, while 28-day mortality, 48-hour and 28-day intubation rates were compared using the Chi-square test. The predictive performances of HR/SpO2 and the ROX index (the ratio of SpO2/FiO2 to respiratory rate) at 4 hours were assessed regarding HFNC failure, which was determined if intubation was given within 48 hours after the initiation of oxygen therapy. The area under the receiver operating characteristic curve (AUC) for HR/SpO2 and the ROX index were calculated and compared.Results: A total of 524,520 inpatient hospitalization records were screened, 106 patients in HFNC group and 106 patients in NIV group were successfully matched. No significant difference in 48-hour intubation rate between the HFNC group and the NIV group (14.2% vs. 8.5%, P=0.278); patients receiving HFNC had higher 28-day intubation rate (26.4% vs. 14.2%, P=0.029), higher 28-day mortality (17.9% vs. 8.5%, P=0.043), longer ICU length of stay (4.4 vs. 3.3 days, P=0.019), compared to those of NIV group. The AUC of HR/SpO2 at 4 hours after the initiation of HFNC yielded around 0.660 for predicting 48-hour intubation, greater than that of the ROX index with an AUC of 0.589 (P<0.01).Conclusions: HFNC therapy cannot completely replace NIV for patients with mild hypercapnia. As opposed to the ROX index, a modest, yet improved predictive performance is demonstrated using HR/SpO2 in predicting the failure of HFNC among these patients.

Abstract Background: The aim of the present study was to evaluate the therapeutic effect of high-flow nasal cannula (HFNC) oxygen therapy on patients with aspiration pneumonia accompanied by respiratory failure in the post-stroke sequelae stage, with the goal of providing more effective oxygen therapy and improving patient prognosis. Methods: Retrospective analysis was conducted on 103 elderly patients with post-stroke aspiration pneumonia and moderate respiratory failure (oxygenation index: 100–200 mmHg) that had been admitted. The patients were divided into two groups according to the mode of oxygen therapy that was used: the Venturi mask group and the HFNC treatment group. The two groups were analyzed and compared in terms of the changes in the blood gas indices measured at different points in time (4, 8, 12, 24, 48, and 72 h), the proportion of patients that required transition to invasive auxiliary ventilation, and the 28-day mortality rate. Results: A total of 103 patients were retrospectively analyzed; 16 cases were excluded, and 87 patients were included in the final patient group (42 in the HFNC group and 45 in the Venturi group). There was a statistically significant difference in the oxygenation indices of the HFNC group and the Venturi group (F = 546.811, P < 0.05). There was a statistically significant interaction between the monitored oxygenation indices and the mode of oxygen therapy (F = 70.961, P < 0.05), and there was a statistically significant difference in the oxygenation indices for the two modes of oxygen therapy (F = 256.977, P < 0.05). HFNC therapy contributed to the improvement of the oxygenation indices at a rate of 75.1%. The Venturi and HFNC groups also differed significantly in terms of the proportion of patients that required transition to invasive auxiliary ventilation within 72 h (P < 0.05). The HFNC group’s risk for invasive ventilation was 0.406 times that of the Venturi group (P < 0.05). There was no statistical difference in the 28-day mortality rate of the two groups (P > 0.05). Conclusion: HFNC could significantly improve the oxygenation state of patients with post-stroke aspiration pneumonia and respiratory failure, and it may reduce the incidence of invasive ventilation.
