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!
The nasal cannula is designed to sit with the prongs facing downward. The two prongs should be inserted into the nostrils to deliver oxygen effectively. The curved part of the cannula should rest comfortably under the chin, ensuring a secure fit.
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 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.
Carnivores have long, pointed, and curved canines to effectively grasp and hold onto their prey. These adaptations allow them to puncture flesh and deliver a lethal bite, facilitating the capture and immobilization of animals they hunt. Additionally, the shape and structure of the canines help in tearing meat, which is essential for their diet. Overall, these features are crucial for their survival and hunting efficiency.
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.
All of them should offer curved couches. I've never been to a furniture store that didn't have curved couches.
