    00:00 Hi, welcome to our respiratory video series. Now on this one, we're going to talk about high-flow oxygen delivery methods. That includes a Venturi mask, a trach collar, CPAP, and BiPAP. Okay now we're going to talk about everything a nurse needs to know to have a basic understanding of each of these methods. Now we're going to start with trach collar because it's a little unique. What does a patient have to have to get the benefit from a trach collar? Right, a trach. Now a tracheostomy is a surgical procedure. The surgeon will make an incision in the neck. Remember your windpipe or your tracheas, it's in front of your esophagus, they will insert a trach tube. Now a trach tube generally has an outer cannula and an inner cannula.

    00:49 That inner cannula can be removed for cleaning or thrown away. But in order to use a trach collar, the patient has to have a tracheostomy. So this won't be one that you use very often unless you're in a specialized kind of unit. So tracheostomy collar will fit right over the trach, it's a high-flow device, it provides oxygen or humidified room air to a tracheostomy. Now the oxygen settings are similar to what we would use for a Venturi mask. How about some trivia? What does an air entrainment mean in oxygen therapy? That's an odd word and you probably haven't heard it before. So let's break it down. Air entrainment is the movement of room air into the chamber of a jet nebulizer used to treat respiratory diseases. Okay, so a Venturi mask is also known as an air entrainment mask. Now we hook that up to oxygen, but it's a high-flow device. Sometimes we use this for patients with COPD but need a very precise oxygen measurement.

    01:54 So that's why these are beneficial because we can more precisely measure the amount of oxygen that's going in to the patient through the mask than we could with say a low-flow device like a nasal cannula. So, we work with COPD patients, they're predominantly who you'll see this on, but they can be used on a variety of patients, helps us with that precise oxygen measurement.

    02:16 Well, how many times can one person use the phrase precise oxygen measurement in a sentence? I know it kind of overkilled on that one, but that's the benefit of a Venturi mask so I want to repeat it over and over again to be sure you're clear on that point. Now it comes with a set of ports or jets, they're all color coated and that's kind of fun or have an attachment that rotates like a little dial to set the FiO₂. So let me give you an example of the kind that comes with different colored ports. So, one Venturi mask may come with like 5 different-sized ports.

    02:53 Now how these ports work is depending on which port you put on that determines the amount of the FiO₂. It's going to range from 24%-60% with a Venturi mask. So the blue one will deliver 2-4 liters, the white one 4-6, and on and on and on. So depending on what you're shooting for with your patient, that will determine the color of the port or adaptor you put on the Venturi mask. Now we have those situated where they have the big end on the bottom and the tiny end on the top. The wider end is the one that will attach to the mask, the smaller end is what the oxygen tubing attaches to.
