I can start with the instruction of the humidifier of the bubbler okay this will add a little bit more moisture some people love it some people can't stand it but I'd like to actually just have this available for anybody who needs and wants to use it there's if you look closely there is a minimum and a maximum level of water I would suggest that you actually just go right above the minimums I've actually had it where people fill this to the top I go to visit them they say oh my gosh Eric I'm feeling wonderful and they're having water running out of their nose as I'm talking with them and that's not that's something that I really don't want you guys to have to go through distill the water is ideal to use when using this but I have had clients use bottled water if necessary back with the distilled water inside the bubbler so actually put this in here it's very basic now when you're working with this right here you're gonna want to make sure that everything is tight enough and if you're gonna be using the bubbler when troubleshooting I've had people call me and say Eric I just haven't felt the machine like I'm getting oxygen and what's going on I'll show up and they'll have the the humidifier or bubbler connected but it will be loose and it won't be bubbling so if you're using this you have to make sure that you actually see these bubbles because if it's a little loose let's let's say if it's a little loose in some areas sometimes and sometimes it's up here that's on really tight okay so if this is a little bit loose there's no bubbles you know it looks like it's everything's working fine and you don't want to crank this down but it just needs to be snug and when you see this you're good as gold so you connect this to the back piece here it straps on then you will connect to this right here okay and I'll actually show you again the nose cannula right here there you go and that's using the humidifier bubbler piece another thing that if you're going to use this you want to make sure that it's not kinked the tubing here and then it's all nice and flowing so it's not like you know a garden hose where you know there's like kinkajou like this would be you know you don't want that so and that is how you use it [Applause] [Applause]
