Invasive mechanical ventilation is a method of partially or completely supporting a patient's breathing. This is a traditional technique, ventilation through endotracheal intubation or tracheostomy for the patient.

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.

Standard ventilators are used in intensive care units to provide optimal ventilation of the lungs. However, they are not suitable for transporting patients requiring mechanical ventilation. In this case, portable ventilators are the perfect choice for patients requiring mechanical ventilation.

Acute respiratory failure is defined as an acute reduction in the ventilatory function of the respiratory system and/or the gas exchange function of the lungs.
