Comparison Physiological Effects According to Preoxygenation Method Using EIT (PreoxyEIT)
Acute Hypoxemic Respiratory Failure
About this trial
This is an interventional treatment trial for Acute Hypoxemic Respiratory Failure focused on measuring electrical impedence tomography, preoxygenation, intubation
Eligibility Criteria
Inclusion Criteria: Adult patients aged 18 or older Acute respiratory failure is defined as follows: Tachypnea over 30 breaths/minute / Symptoms or signs of respiratory failure / PaO2/FiO2 less than 300 When there is an indication for endotracheal intubation for mechanical ventilation When sufficient information and a consent form for the study are obtained from the patient or the patient's guardian Exclusion Criteria: Coma with Glasgow score < 8 Endotracheal intubation during CPR Contraindications for NIV: poor patient cooperation, recurrent vomiting, GI bleeding, severe craniofacial injury, upper airway obstruction, etc. Contraindications for RSI: complete upper airway obstruction, severe trauma obscuring cervical structures, etc. Implanted electronic medical devices (defibrillator, pacemaker or spinal cord stimulator) Skin damage or inadequate electrode contact due to wound dressing at the electrode site BMI > 50 Polydipsia Unmeasurable SpO2 Pregnancy or lactation
