High flow nasal cannula improves lung aeration and enhances CO2 removal in hypoxemic critically ill patients

چکیده
Methods We performed a prospective randomized cross-over study on hypoxemic (PaO2/FiO2 ≤300 mmHg) non-intubated patients admitted to Intensive Care Unit of San Gerardo Hospital. We delivered the same air/oxygen mix by HFNC (40 L/min) and facial mask for 20 minutes by random order. Continuous recordings of lung aeration and minute ventilation by Electrical Impedance Tomography (EIT) and of inspiratory effort by esophageal pressure swings (ΔPes) were obtained.

Description of the Clinical Course and Severity Score Progression in Critically Ill Children with Acute Bronchiolitis on High-Flow Nasal Cannula Support
Background and Objective: Bronchiolitis is one of the main causes of morbidity and mortality in children. High-flow nasal cannulas (HFNCs) are an alternative for managing moderate to severe cases. Our aim was to describe the outcomes in critically ill children with bronchiolitis who receive HFNC support. Materials and Methods: This was a retrospective cohort study of critically ill children wh...
متن کاملHigh-flow nasal cannula oxygen in critically ill adults: do the nose or lungs know there's a difference?
Intra-nasal oxygen was introduced by Arbuthnot Lane in 1907, using rubber nasal catheters. This approach was advocated by Adrian Stokes for use in critically ill victims of phosgene gas warfare during World War I.1 However, placement of rubber catheters into the nasal cavity (and often removal) was quite uncomfortable and required some skill (it makes our eyes water just thinking about the proc...
متن کاملHigh-Flow Nasal Cannula Oxygen Therapy in Adults: Physiological Benefits, Indication, Clinical Benefits, and Adverse Effects.
High-flow nasal cannula (HFNC) oxygen therapy is carried out using an air/oxygen blender, active humidifier, single heated tube, and nasal cannula. Able to deliver adequately heated and humidified medical gas at flows up to 60 L/min, it is considered to have a number of physiological advantages compared with other standard oxygen therapies, including reduced anatomical dead space, PEEP, constan...
متن کاملWhat every intensivist should know about using high-flow nasal oxygen for critically ill patients
The most conventional forms of oxygen delivery rely on facemasks, a nasal cannula or nasal prongs. However, the use of these methods is limited by certain drawbacks, including the need for a flow of oxygen higher than 15L/min in case of severe hypoxemia or the dilution of administered oxygen by entrained room air in cases of high inspiratory flow. An alternative to conventional oxygen therapy h...
متن کاملHigh-Flow Nasal Cannula Versus Bag-Valve-Mask for Preoxygenation Before Intubation in Subjects With Hypoxemic Respiratory Failure.
BACKGROUND Critically ill patients with respiratory failure undergoing intubation have an increased risk of hypoxemia-related complications. Delivering oxygen via a high-flow nasal cannula (HFNC) has theoretical advantages and is increasingly used. This study was conducted to compare HFNC with bag-valve-mask (BVM) for preoxygenation and to assess oxygenation during intubation in subjects with h...
