Is high-flow safer than low-flow nasal oxygenation for procedural sedation?

Airway management: High flow nasal oxygenation

Minitracheostomy for effective pulmonary toilet was performed on day 5. However, he maintained a saturation of 94%, PaO2 of 64 mmHg and respiratory rate of 35–40 on ventimask. He was advised HFNC oxygenation with a peak inspiratory flow of 50 L/min and FiO2 of 60% initially by device (AIRVO 2 ® Fisher Packel, Auckland, New Zealand). Initially, the patient showed improved saturation to 100% with...

High-Flow Nasal Interface Improves Oxygenation in Patients Undergoing Bronchoscopy

During bronchoscopy hypoxemia is commonly found and oxygen supply can be delivered by interfaces fed with high gas flows. Recently, the high-flow nasal cannula (HFNC) has been introduced for oxygen therapy in adults, but they have not been used so far during bronchoscopy in adults. Forty-five patients were randomly assigned to 3 groups receiving oxygen: 40 L/min through a Venturi mask (V40, N =...

Nasal high-flow therapy delivers low level positive airway pressure

BACKGROUND The aim of this prospective study was to determine whether a level of positive airway pressure was generated in participants receiving nasal high flow (NHF) delivered by the Optiflow system (Fisher and Paykel Healthcare Ltd, Auckland, New Zealand) in a cardiothoracic and vascular intensive care unit (ICU). METHODS Nasopharyngeal airway pressure was measured in 15 postoperative card...

High Flow Nasal Cannula oxygenation for adult patients in the ICU: a literature review.

Oxygenation using High Flow Nasal Cannula (HFNC) was initially described in neonatal medicine, but, gradually, its use has extended to adult patients. The efficacy of the device has been linked to higher flows of oxygen delivered to the patients, air tract humidification, alveolar recruitment through a positive end-expiratory pressure (PEEP) effect, prevention of nasopharyngeal collapse, and de...
