When a non-rebreathing mask is intolerable for the patient. Patients with physical injuries, chronic airway obstruction, cluster headaches, and smoke inhalation use non-rebreather masks.
<h3>When is it appropriate to employ a nasopharyngeal airway?</h3>
A patient's nostril is entered with a thin, transparent, flexible tube called a nasopharyngeal airway (NPA). Bypassing upper airway congestion at the level of the nose, nasopharynx, or base of the tongue is the goal of the NPA. In order to avoid obstruction, it also prevents the tongue from falling backward against the pharyngeal wall.
<h3>Which of the following patients can be treated with nasopharyngeal airways?</h3>
For patients with an intact cough and gag reflex, NPAs can be used in patients who are aware, semiconscious, or unconscious, unlike oral airways.

These solids, diamond and graphite are first naturally occurring inorganic substances and have an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.
<h3>Standard temperature and pressure of diamond and graphite</h3>
At standard temperature and pressure, the two minerals; diamond and graphite which are both composed of carbon atoms are Allotropes of Carbon. Additionally, peculiar difference between them exists in the delocalization of electrons in one as opposed to the other.
- Similarly, these solids are minerals and are naturally occurring inorganic element or compound having unique structures.

Answer:
d. Latin America, Asia, and Africa
Answer:
9/5
Explanation:
original fraction : x/y
new fraction = .9x/(.5y)
= 9x/5y
(9x/5y) / (x/y)
= 9x/5y * y/x
= 9/5
= 1.8
so it increased by 80%
e.g suppose we had 100/200 or 1/2
new fraction = 90/100 or 9/10
new ratio = (9/10) / (1/2)
= 9/5
