What is the difference between standard and flare-tip cannulas?

,
In short, flare-tip cannulas more easily trigger a pulse from the EDS pulse-demand oxygen system. As you know EDS stands for our Electronic Delivery System (Pulse-Demand™). The triggering of the system depends on the EDS unit sensing…

If my oxygen system has more than one oxygen cylinder and they share a common manifold what will the pressure read? Why does the pressure drop a little sometime after the fill?

,
Regardless of the size of, or number of oxygen bottles in your aircraft if they share the same manifold the system will always read whatever the final pressure is. During an oxygen transfill the tank being filled will heat up. This causes the…

,
It doesn't need one. The standard passenger constant-flow mask primarily has the bag so that the FAA requirement of flow indication can be satisfied. It is not needed on the ALPS face mask because the EDS provides a positive indication of…

How does a standard aviator’s oxygen mask work and why does it have a bag hanging at the bottom?

,
The standard passenger constant-flow mask primarily has the bag so that the FAA requirement of flow indication can be satisfied. Additionally, the standard aviators oxygen mask that we know of today has evolved from a medical mask where knowing…

Does Breathing Deeper Help Oxygen Saturation While Flying?

,
Q: I fly cross country a lot just below class 'A' airspace with my EDS and recently got a portable pulse oxymeter. I’ve noticed that my saturation rate frequently falls below 90% at altitudes around 16K to 18K ft. However, if I breathe a few…
