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 ...
Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. [4] [5] LPR causes respiratory symptoms such as cough and wheezing [6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. [7]
Airway management is commonly divided into two categories: basic and advanced. Basic techniques are generally non-invasive and do not require specialized medical equipment or advanced training. Techniques might include head and neck maneuvers to optimize ventilation, abdominal thrusts , and back blows.
Pharyngeal aspiration introduces a substance into the pharynx for aspiration into the lungs. It is less technically difficult than intratracheal instillation the pharynx is higher in the respiratory system than the trachea. Pharyngeal aspiration is the introduction of a substance into the pharynx and its subsequent aspiration into the lungs
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
The tube is then marked at this level to ensure that the tube has been inserted far enough into the patient's stomach. Many commercially available stomach and duodenal tubes have several standard depth markings, for example 46 cm (18 in), 56 cm (22 in), 66 cm (26 in) and 76 cm (30 in) from distal end; infant feeding tubes often come with 1 cm ...
Air rushes into the lungs in order to equalise the pressure. The glottis closes (muscles innervated by recurrent laryngeal nerve ) and the vocal cords contract to shut the larynx. The abdominal muscles contract to accentuate the action of the relaxing diaphragm; simultaneously, the other expiratory muscles contract.
Throat swab. Differentiating a viral and a bacterial cause of a sore throat based on symptoms alone is difficult. [29] Thus, a throat swab often is done to rule out a bacterial cause. [30] The modified Centor criteria may be used to determine the management of people with pharyngitis. Based on five clinical criteria, it indicates the ...
