In the emergency resuscitation steps, ensuring breathing and heart rate is one of the first factors that determine the patient's survival. Currently, at Vinmec Phu Quoc Hospital, continuous positive airway pressure has been applied in many clinical cases to support the recovery of respiratory capacity for patients with a success rate of up to 95%.

Continuous positive airway pressure (CPAP) in the treatment of acute respiratory failure in children who are still able to breathe on their own but still cannot provide enough oxygen for the body, by creating a continuous positive pressure throughout the breathing cycle.

Continuous positive airway pressure or CPAP is a treatment support method commonly used for children with respiratory failure who are still able to breathe on their own at current medical facilities. Indications for CPAP for children are very diverse but all aim to reduce the risk of mechanical ventilation and provide non-invasive respiratory support for children.

Hyaline membrane disease is a common disease in premature infants, when the lungs are not yet fully developed, leading to severe respiratory failure. This is one of the leading causes of death in premature infants. The incidence is about 1% of all newborns and 5 - 10% of premature infants.

Respiratory failure is a condition in which the respiratory system is unable to maintain gas exchange according to the body's needs. Ensuring the body's oxygen supply is an important factor in determining the patient's life. Continuous positive airway pressure in the treatment of respiratory failure helps reduce symptoms of respiratory failure and restore respiratory function. Thanks to this method, the use of invasive methods is limited, thereby limiting the risk of complications.

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.

signs of sleep apnea usually maintain airway patency when awake but when deep sleep is obstructed, leading to deep sleep being interrupted by increasing respiratory obstruction and stimulating the patient to wake up to enter light sleep. This awakening helps the patient's airway to re-establish a normal state and is often accompanied by a long inspiration to compensate for the lack of oxygen.
