I've worked in hospitals and have always been taught that the nasal cannula should curve downwards. Cant give much justification as to why though..sorry!
Wear a cannula so that it causes a minimum of discomfort. The nasal cannula is a small piece of plastic tubing that is attached to a larger tube which, in turn, connects to the oxygen container. The cannula has two small prongs that are inserted into the nostrils. If the prongs are curved, they should point downward inside the nostrils.
Kookie, it is a type of building that is curved on the sides and pointed on the top.
It's pretty straightforward. Most cannulas have tips that are inserted into the nostrils, and the tips are normally shorter than 1/4 an inch. Here's a pic of what they look like:http://www.vitalitymedical.com/isroot/Stores/VitalityMedical/picxl/BAX001311.jpgThen you just wrap the tubing around your ears and it will hold in place.
The more pointed a mountain, the newer it is. Thus, the flatter the mountain, the more erosion it's been exposed to, thats how plateau mountins form
Curved tail, pointed ears, usually brown or black with some white, blue eyes.

A horn is a hard permanent outgrowth, often curved and pointed, found in pairs on the heads of cattle, sheep, goats, and giraffes.
The solid that has one flat face, one curved face, one edge, and one vertex is a cone. The flat face is the circular base, the curved face is the conical surface, the edge is the circular boundary where the base meets the curved surface, and the vertex is the pointed tip of the cone.
All of them should offer curved couches. I've never been to a furniture store that didn't have curved couches.
A rectangle with pointed ends is called a "gothic arch." This architectural element is commonly found in Gothic architecture, characterized by its pointed shape at the top. Gothic arches are known for their structural integrity and ability to support heavy loads due to the way forces are distributed along the curved lines of the arch.

Assuming you're doing this for someone else:1) pull the plastic slide down so that the cannula will definitely be large enough to fit the patient2) hold the cannula with both hands so that the prongs are facing away from you and curving down3) put the prongs into the patient's nostrils4) pull the tubes over and behind both of the patient's ears at the same time5) adjust the plastic slide back up so that the cannula isn't tight enough to bother the patient yet the cannula won't slide off.
