Respiratory failure occurs more often in premature babies, the earlier the baby is born, the higher the risk of the disease. To comprehensively assess the child's condition, it is necessary to combine methods from understanding the medical history, the severity of the disease, and paraclinical tests.

Oxygen therapy for patients with chronic obstructive pulmonary disease (COPD) is effective in treating acute exacerbations as well as long-term treatment at home. So what are the specific roles and benefits of this therapy?

Currently, oxygen therapy is widely used in the treatment of respiratory failure. Depending on the cause of hypoxia, the doctor will prescribe oxygen therapy to suit the patient's condition.

High-flow oxygen therapy via nasal cannula provides positive pressure support to the oropharynx, creating positive end-expiratory pressure in the lower airway. This effect is similar to that of continuous positive airway pressure ventilation, which exerts a force to keep the alveolar airways from collapsing due to increased surface tension during expiration.

High-flow oxygen therapy via nasal cannula is applied in cases of patients with acute hypoxemic respiratory failure, postoperative respiratory failure, acute pulmonary edema, acute heart failure, sleep apnea... with good results. However, this therapy also has many limitations.

High-flow nasal cannula oxygen therapy can significantly reduce both mortality and intubation rates in immunocompromised patients with acute respiratory failure, improving dyspnea and comfort in patients presenting to the emergency department with dyspnea and/or hypoxemia.

Oxygen therapy is indicated for patients with signs of hypoxia such as low oxygen concentration or low arterial blood oxygen saturation. Nasal and tracheostomy tubes provide oxygen to patients with the aim of reducing shortness of breath, preventing and treating hypoxia.

Oxygen therapy using spectacles is often performed for patients who need oxygen. The purpose of this technique is to provide a high oxygen content of inhaled air for the patient to breathe easily, meeting the body's metabolic needs.
