Abstract

Objectives: The Helmet-NIV was first approach in 1990s in Chicago, then became more popular in COVID-19, this study was conducted to evaluate the effectiveness of non-invasive ventilation with helmet system on patients with acute respiratory failure. Method: a prospective interventional study, data was collected on all patients diagnosed with acute respiratory failure in mild and hard degree who were on Helmet NIV during the period from June 2022 to June 2023. Clinical indicators and blood gases were evaluated before and after Helmet-NIV. Results: A 30-patients study with the ratio male/female 2:1, mean age: 67,7±12,805; the common classfication of age is 60-80 years old. The most common cause of acute respiratory failure was pneumonia (23,3%), followed by acute pulmonary edema (30%) and COPD exacerbations (23,3%). 56,7% of patients had underlying disease and 46,7% of patients had acute onset of disease; 63,3% patients with severe respiratory failure. The success rate with helmet NIV was 33,3% (10/20 patients). Helmet NIV was effective in improveing aterial blood gas parameters after 24 hours of intervention, specifically: pH (7,344 versus 7,465), PaO2(74,15 versus 122), PaCO2 (39 versus 45,5), P/F ratio (179,2 versus 322,8). There were statisticlly significant (p<0,05). Conclusion: Helmet NIV is effective in improving aterial blood gas parameters in patients with pulmonary edema, the effective of Helmet-NIV in patients with COPD and pneuminia is not obivious
