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 ...
Ventilator-associated pneumonia (VAP) is a sub-type of hospital-acquired pneumonia (HAP) which occurs in people who are receiving mechanical ventilation. VAP is not characterized by the causative agents; rather, as its name implies, definition of VAP is restricted to patients undergoing mechanical ventilation while in a hospital.
Laryngospasm is a primitive protective airway reflex that functions to protect against aspiration. However, it may be detrimental if there is sustained closure of the glottis resulting in blockage of respiration that hinders the free flow of air.
The endotracheal tube is a guaranteed mechanism to secure a compromised airway, limit aspiration, and bring about mechanical ventilation in comatose patients. The endotracheal tube is a great method for patients who are comatose, have an obstructed airway, or need mechanical ventilation.
The pre-hospital setting provides unique challenges to management of the airway including tight spaces, neck immobilization, poor lighting, and often the added complexity of attempting procedures during transport. When possible, basic airway management should be prioritized including head-tilt-chin-lift maneuvers, and bag-valve masking.
Suctioning can prevent pulmonary aspiration, which can lead to lung infections. In pulmonary hygiene, suction is used to remove fluids from the airways, [1] to facilitate breathing and prevent growth of microorganisms. Small suction-providing devices are often called aspirators.
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 ...
Droplet precautions are intended to prevent transmission of pathogens spread through close respiratory or mucous membrane contact with respiratory secretions. Preventative measures such as personal protective equipment can be worn to prevent direct contact with mucous membrane and respiratory secretion.
