The goal of this analytical experimental study is to evaluate whether high-flow tracheal oxygen therapy at flow rates above 60 L/min increases end-expiratory lung impedance in tracheostomized patients in the intensive care unit. The main question it aims to answer is whether high-flow tracheal oxygen therapy improves end-expiratory lung impedance in tracheostomized patients. This study will be conducted in the Intensive Care Unit of Sanatorio Parque in Rosario, Santa Fe, Argentina, between December 1, 2024, and March 31, 2025. The participant population consists of adult ICU patients (≥18 years old) who are tracheostomized, have undergone at least 10 days of mechanical ventilation, and can tolerate spontaneous breathing for at least 12 hours. By analyzing the effects of high-flow tracheal oxygen therapy on lung function, this study aims to generate valuable insights into its physiological impact, potentially influencing clinical management strategies for tracheostomized patients in intensive care settings.

High-Flow Tracheal Oxygen is the use of high oxygen flows in tracheostomized patients. Unlike conventional oxygen therapy which is performed through siliconized nasal prongs, this is done through a connector directly on the tracheostomy tube.

End-Expiratory Lung Impedance
End-Expiratory Lung Impedance refers to the electrical impedance of lung tissue measured at the end of expiration, serving as a non-invasive indicator of end-expiratory lung volume (EELV). In the context of high-flow oxygen therapy, changes in EELI reflect variations in lung aeration and recruitment in tracheostomized patients.
Time frame: From enrollment to the end of treatment at 120 minutes for each patient
Respiratory rate
Respiratory rate refers to the number of breaths a person takes per minute.
Time frame: From enrollment to the end of treatment at 120 minutes for each patient
Arterial oxygen saturation
Arterial oxygen saturation refers to the percentage of hemoglobin in the arterial blood that is bound to oxygen. It is a key indicator of oxygenation efficiency and respiratory function
Time frame: From enrollment to the end of treatment at 120 minutes for each patient
