HFOT: Unlocking the Benefits of High-Flow Oxygen Therapy in UVENT-S ICU Ventilators (VIDEO)

High-Flow Oxygen Therapy (HFOT) is a medical treatment that involves the delivery of a high flow of heated and humidified oxygen to a patient through a nasal cannula (HFNC). It is commonly used in the management of respiratory conditions such as acute respiratory failure, pneumonia (1), and chronic obstructive pulmonary disease. (2) HFOT is designed to provide a higher flow rate of oxygen compared to traditional oxygen therapy (3), which can improve oxygenation and reduce the work of breathing (4).

That’s why we paid special attention to the implementation of HFOT in our ventilators. We were aimed at the patient’s comfort and safety during respiratory support, as well as on possible improvements in therapy. So high flow oxygen therapy special mode in UVENT-S ICU ventilators has a number of advantages.

Advantages of HFOT in UVENT-S ventilators

• Wide range of flow rate setting (up to 80 l/pm) to facilitate the setup to increase FRC and effectively compensate early signs of respiratory failure.
• Automatic oxygenation therapy based on SpO2 feedback with timely control and maintenance of minimum-effective inspired oxygen concentration.
• High-quality humidification and heating of the breathing mixture for optimal breathing comfort.
• Compatible with high-flow O2 cannulas.
• The mode is already included in the basic configuration of the UVENT-S.

HFOT clinical applications

Acute Respiratory Failure: HFOT is commonly employed in the management of patients with acute respiratory failure, whether due to conditions like pneumonia, acute respiratory distress syndrome (ARDS), or other respiratory illnesses (1).

Chronic Obstructive Pulmonary Disease (COPD): It may be used in exacerbations of COPD to provide respiratory support and improve oxygenation. (2)

Hypoxemic Respiratory Failure: HFOT may be considered for patients with hypoxemic respiratory failure who require a higher level of oxygen support. (3)

Post-Operative Care: HFOT can be utilized in the post-operative period, especially for patients recovering from thoracic or upper abdominal surgeries. (5)

Preventing Intubation: Among patients with acute hypoxaemic respiratory failure, HFNC was proven to avoid intubation compared to conventional oxygen devices. (6,7)

This list is not a recommendation or direct instruction for action by physicians. It does not replace the clinical judgment of a physician and is not to be used for clinical decision making purpose. Also, the list does not claim to be complete description of the range of clinical applications.

So, essentially the therapy aims to enhance oxygenation, reduce the work of breathing, and improve respiratory comfort for patients with respiratory distress. While HFOT is a valuable tool in respiratory care, its appropriateness and effectiveness depend on the specific clinical context and the patient’s condition. Medical professionals assess and prescribe HFOT based on individual patient needs and the underlying respiratory pathology.
