Aspiration pneumonia, a lung infection caused by pulmonary aspiration; Aspiration thrombectomy, embolectomy where a thrombus is removed by suction; Bone marrow ...
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents.In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages and East Asian languages, the difference is contrastive.
The voiceless glottal fricative, sometimes called voiceless glottal transition or the aspirate, [1] [2] is a type of sound used in some spoken languages that patterns like a fricative or approximant consonant phonologically, but often lacks the usual phonetic characteristics of a consonant.
Preaspiration is comparatively uncommon across languages of the world, [4] and is claimed by some to not be phonemically contrastive in any language. [5] Ladefoged & Maddieson (1996) note that, at least in the case of Icelandic, preaspirated stops have a longer duration of aspiration than normally aspirated (post-aspirated) stops, comparable to clusters of [h] +consonant in languages with such ...
Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
Aspiration pneumonia most often develops due to micro-aspiration of saliva, or bacteria carried on food and liquids, in combination with impaired host immune function. [30] Chronic inflammation of the lungs is a key feature in aspiration pneumonia in elderly nursing home residents and presents as a sporadic fever (one day per week for several ...
Pharyngeal aspiration is widely used to study the toxicity of a wide variety of substances, including nanomaterials such as carbon nanotubes. [2] Pharyngeal aspiration has benefits over the alternative methods of inhalation and intratracheal instillation, the introduction of the substance directly into the trachea. Inhalation studies have the ...
