Vocal resonation. Vocal resonance may be defined as "the process by which the basic product of phonation is enhanced in timbre and/or intensity by the air-filled cavities through which it passes on its way to the outside air." [1] Throughout the vocal literature, various terms related to resonation are used, including: amplification, filtering ...
93.93. MeSH. D012121. [ edit on Wikidata] Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration in which a rescuer presses their mouth against that of the victim and blows air into the person's lungs. [1] [2] Artificial respiration takes many forms, but generally entails providing air ...
Nasopharyngeal airway. In medicine, a nasopharyngeal airway, also known as an NPA, nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl [ de] in 1958. [1]
The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen ...
A surgical mask serves as a mechanical barrier that interferes with direct airflow in and out of respiratory orifices (i.e. nose and mouth).Most commonly used surgical masks are designed to only trap respiratory droplets, and therefore do not filter or block fine airborne particles that are smaller than the designed filtration ratings, which may be transmitted by coughs, sneezes, unintentional ...
Continuous positive airway pressure ( CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person. The application of positive pressure may be intended to prevent upper airway collapse, as occurs in ...
Facies. Facial abnormalities associated with Crouzon syndrome. Specialty. Medical genetics. In medical contexts, a facies is a distinctive facial expression or appearance associated with a specific medical condition. [1] The term comes from Latin for "face".

Respirator. White, disposable Standard N95 filtering facepiece respirator. A half-face elastomeric air-purifying respirator. This kind of respirator is reusable, with the filters being replaced periodically. Lab worker wearing a powered air-purifying respirator.

Dust mask. A dust mask is a flexible paper pad held over the nose and mouth by elastic or rubber straps for personal comfort against non-toxic nuisance dusts. They are not intended to provide protection from toxic airborne hazards. [1] [2] The European FFP1 mask, the lowest-grade mechanical filter respirator available in the jurisdiction, is ...
Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. [1] The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones and sphenoid bone in ...
