oxygen delivery devices and flow rates chart
Oxygen Delivery Devices Delivery Device Minimum to Maximum Liter Flow Range Adults Approximate O2 Delivered Notes RT assistance recommended for liter flows of 6 litersminute or more. A flow rate of 2 liters per minute increases the FiO2 from 21 percent room air to.

High-flow warmed and humidified nasal oxygen For patients who need higher concentrations of oxygen at flow rates of 10-40 liters per minute.
. 2 to 15 Lmin. Nasal Cannula 1-6 litersminute 25-50 Humidifier recommended for all flow rates 4 litersminute High Flow Nasal Cannula 1-15 litersminute 25-50 High. The percentage of oxygen delivery depends on the flow rate and the delivery device.
Low flow device Most common device used for mild hypoxia Can be set between 1 and 6 LPM 24 to 40 FiO2 FiO2 increases approximately 4 with each liter of O2 KorupoluR GJ Needham DMContemporary CriticalCare. The flow rate is how many liters of oxygen per minute your device delivers. Hudson Nonrebreather Teleflex Medical 1012 80100.
Nasal cannulae Teleflex Medica 1. These devices deliver a variable inspired oxygen concentration to the patient which depends on the PIFR. Only goes up to 60 FIo2 so not for patients who have significantly high oxygen demands bulky.
Prompt clinical assessment is required if oxygen therapy needs to be initiated or increased due to a falling saturation level. Per minute will deliver approximately 24. The nasal cannula is a device that has two prongs that are placed in the patients nostrils and deliver oxygen at flow rates of 1 to 6 liters per minute.
Reduce the work of breathing. Lmin 1 Resultant oxygen concentration. Hudson mask Teleflex Medical 56.
Can delivery precise and dependable FiO2. Oxygen delivery device Oxygen flow rate. Deliver 24-30 O2 this is an FiO2 of 024-03 Flow rate maximum 4Lmin.
4 rows Oxygen flow through a TTOC ranges between 05 and 4 Lmin 1. Both high-flow and low-flow oxygen delivery systems are capable of administering a wide range of FiO 2However the terms high and low do not reflect the delivered FiO 2. 22 to 60 oxygen with appropriate oxygen flow rates of 05 to 2 Lminute.
2 A simple face mask is a low-flow oxygen device. Oxygen saturation and delivery system including flow rate should be recorded on the patients monitoring chart. Ensure adequate clearance of secretions and limit the adverse events of hypothermia and insensible water loss by use of optimal humidification dependent on mode of oxygen.
Give oxygen therapy in a way which prevents excessive CO 2 accumulation - ie. In fact it refers to the flow of gas delivered to the systemLow-flow systems are used in more critically stable patients. Oxygen delivery by TTOC.
A minimum of 6 Lminute of oxygen flow is needed 2to prevent rebreathing of exhaled carbon dioxide. Depending on a patients inspiratory effort tidal volume speed of inspiration and respiratory rate the PIFR can often exceed the flow rate at which oxygen or an oxygenair mixture is supplied by the device meaning that at the time of PIFR. 200969111 Bailey P Thomsen GE Spuhler VJ et alCrit Care MedJan2007351139145.
Oxygen delivery devices and flow rates should be adjusted to keep the oxygen saturation in the target range. For example patients commonly use a flow rate of 2 liters per minute but the flow rate varies by each patients needs. They deliver oxygen at flow rates below the patients respiratory requirements.
Selection of the appropriate flow rate and delivery device. Different devices tolerate different flow rates from 0-15Lmin and this flow rate can be set on the wall tap. The main type of oxygen deliver device are outlined below.
Reservoir cannula As mentioned previously reservoir cannulas improve the efficiency of oxygen delivery saving two to four times the oxygen delivered via continuous flow. 1L 24 2L 28 3L 32 4L 36 5L 40 6L 44. A simple face mask can deliver 35 to 60 oxygen with an appropriate flow rate of 6 to 10 Lminute.
1 to 6 liters. Adapters deliver set amounts of FiO2 at 24 to 60.
