1. Fixed performance devices. These devices deliver a fixed inspired oxygen concentration to the patient, independent of the PIFR. Even at the time of PIFR no random entrainment of room air will occur to unpredictably alter the FiO2 with this equipment. Devices in this group include: Venturi mask

One of the primary treatment modalities that is used as a Respiratory Therapist is oxygen therapy. Therefore, it is important to understand how much \(FiO_2\) we are giving our patients depending on what delivery system we are using. An oxygen delivery system is a device used to administer, regulate, and supplement oxygen to a patient in order to increase the arterial oxygenation.

Ubbo F. Wiersema, in Cardiothoracic Critical Care, 2007. Venturi Mask. With the Venturi mask system, oxygen inflow is connected to a specific color-coded entrainment device at the base of the mask that provides a set F I o 2 at a set oxygen inflow rate. Various entrainment devices can provide an F I o 2 of 0.24 to 0.5, with an oxygen inflow of 4 to 15 l/min and a total flow delivered to the ...

B Oxygen Delivery Systems. With the exception of anesthetic breathing circuits, virtually all O 2 delivery systems are nonrebreathing. In nonrebreathing circuits, the inspiratory gas is not made up in any part by the exhaled tidal volume (V T), and the only CO 2 inhaled is that in any entrained room air. To avoid rebreathing, exhaled gases must be sequestered by one-way valves, and inspired ...

The % of oxygen delivery depends on the flow rate and the delivery device. Delivery devices include: Nasal cannula Delivers 24-30%. Comfortable. Flow rate 1-4L/min. Use for non-acute ward use, or if mildly hypoxic. Hudson mask Delivers 30-40%. Flow rate 5-10L/min. Step up from nasal cannula but doesn’t deliver specific % of oxygen like venturi.

Controlling the velocity of pure oxygen flow into the Venturi device determines the amount of atmospheric air mixed with oxygen inside these devices. This controlled mixing helps to deliver a predetermined fraction of oxygen in inhaled air (FiO 2) to the patient. Venturi devices are usually available in the following FiO2 delivery options: 24% ...

Jul 15, 2017 · With respiratory distress, a patient’s inspiratory flow rate can range from 30 – 120 L/min which far exceeds the flow rate provided by some oxygen delivery devices. Only more advanced oxygen delivery systems (Venturi mask, high flow nasal cannula) allow fine tune control over the delivered FiO 2.
