Appropriate Use of Oxygen Delivery Devices

Abstract

Abstract:Oxygen supplementation is one of the commonest drugs required for a patient in hospital. Appropriate oxygen supplementation as per the requirement of the patient is essential. This requires optimal oxygen delivery device from the vast armamentarium. This requires understanding basics of oxygen delivery devices and its appropriate selection. This review describes various commonly available devices. The author would also propose a chart for aiding oxygen delivery devices based on the existing literature.

High-Flow Therapy by Nasal Cannulae Versus High-Flow Face Mask in Severe Hypoxemia After Cardiac Surgery: A Single-Center Randomized Controlled Study—The HEART FLOW Study

“…The face mask was positioned to ensure a good fit and set to 15 L/min assuming this gas flow corresponded to an F I O 2 of 100%. [13][14][15] There was no continuous positive airway pressure valve on the face mask. As previously described in the authors' pilot study, 12 the F I O 2 (in HFNC group) or gas flow (in HFFM group) was adjusted according to the SpO 2 .…”

“…The co-primary endpoints were PaO 2 /F I O 2 at 1 and 24 hours. The F I O 2 was determined as follows: the F I O 2 set on the device for HFNC or on the ventilator for NIV, F I O 2 of 100% for HFFM 15L/min, [13][14][15] the F I O 2 specified on the manufacturer datasheet for Venturi mask, or corresponding to the oxygen flow for nasal prongs delivering low-flow oxygen. 16 Fig 1.…”

“…In addition to that, its indication will depend on the patient's need and its target saturation defined, on the severity of hypoxemia, on the need for the inspired O 2 concentration control degree, and on the patient's tolerance to the device in use. For example, high-flow devices such as Venturi masks, should be carefully evaluated for patients at risk of carbon dioxide retention [18][19][20][21] .…”

Approach to Optimal Oxygen Therapy in the Management of COVID-19 Patients during Pandemic: An Indian Perspective

“…Venturi-mask (VM) and high-flow nasal cannula (HFNC) are high-flow fixed performance devices. [31][32][33][34][35] High-flow delivery device unlike low-flow system ensures that the entire oxygen requirement of the patient is met by the device irrespective of his/her inspiratory effort and is not necessarily defined by flow rates. Any of these devices should be introduced at a particular level depending on the respiratory status of the COVID-19 patient and is usually decelerated from HFNC to SFM/ NC in a step-wise manner (Table 2, Flowchart 1).…”

“…Venturi masks (FiO 2 0.24-0.28) are best suited for COVID-19 patients with carbon dioxide retention among COPD patients, wherein overzealous oxygen therapy can worsen hypercapnia. 22,[32][33][34]…”
