Positive pressure ventilation helps reduce hospital-acquired infections, especially pneumonia; patients are comfortable, able to communicate, eat orally, maintain personal activities, or can breathe at home.

As millions of people across the United States and around the world battle COVID-19, many patients are having difficulty breathing, and ventilators have become a top priority for healthcare workers to help patients survive. Now, the shortage of ventilators is becoming more and more severe.

Ventilators have become a symbol of the COVID-19 pandemic, the last hope for survival for patients who cannot breathe on their own. However, when they need a ventilator, their condition is at its most serious.

Non-invasive ventilation has proven to be effective in the treatment of acute respiratory failure, especially in patients with chronic obstructive pulmonary disease. Non-invasive ventilation equipment should be available 24 hours a day in the hospital for treatment.
