My understanding was that the risk of air entering the esophagus and stomach lied around the 18 cmH2O mark, so moderate amounts of positive pressure support could lead to issues, even in the act of spontaneous breathing.

I opened a sim lab in Canada that was supposed to be an off shoot from an aviation training model. In aviation, there are several levels of fidelity, any of which can be applied to the skill being assessed. Very low fidelity models are used for the most basic tasks and you work your way up...

It doesn't hurt to read JEMS or EMS World as both have decent content while advertising emerging technologies. However if you want a research based publication, Prehospital Emergency Care has more empirical evidence geared towards practice. Keep in mind that what is studied in some regions may...

As an aside for apneic oxygenation, when assessing brain death in the hospital, one of the tools is an apnea test. In this test, you remove mechanical ventilation and perform a series of ABG's to see the rise in PCO2 (obviously if there are registered breaths during the test, the patient is not...

Any particular topic?

If you need routine questions answered, I would suggest setting up something up on surveymonkey.com and request feedback from people? I see this all the time on other forums.

The theory behind nasal cannula being limited to 6 Lpm is based on the natural reservoir created by the naso-oropharynx. It is felt that as you increase litre flow, more and more of this cavity will be filled with oxygen, creating a bolus of oxygen. Beyond 6 Lpm, however, the cavity is filled...

Sorry all, stepped away for a bit...yes, this setup is an armful of respiratory pieces that can fit together...so here's what they did to provide humidification for nasal cannula (starting at the oxygen outlet): hook up a high humidity nebulizer made to attach to wide bore tubing, which goes to...

Regarding the quote from a textbook, I have to caution that we shouldn't take things from texts unless they are referenced. Anyone can write a text and use "experts" to fill in the blanks. As we know, the death knell for quality is doing something because "we've always done it this way and it...

Pocket masks were designed to be used by the lay person and now that they recommend compressions only for one person CPR, they should still be carried in the event that two people are there and want to do something for the patient. For the skilled medic, BVM's are far superior for their...

First, consider the role of the pressure generated by CPAP and not the flow used to create it, because these are often confused. Consider individual alveoli as being bunches of balloons. We all know from personal experience that the hardest part of the balloon is getting them open at the very...

Actually, silicon is the natural element, silicone is the synthetic commercial product from which many things are made.

I've used the Crossvent extensively for long, LONG fixed wing transports (like, days). A durable and very capable machine that had few issues. That being said, the service that I was with looked at 4-5 different devices when looking to upgrade the fleet and found the Crossvent to be lacking in...
