• trachea
  • These cartilages control airflow into and out of the trachea (windpipe) during breathing. (msu.edu)
  • During swallowing, normal laryngeal function protects the airway by closing the opening to the trachea and preventing aspiration of food or water. (msu.edu)
  • Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. (wikipedia.org)
  • this is referred to as extubation of the trachea (or decannulation, in the case of a surgical airway such as a cricothyrotomy or a tracheotomy). (wikipedia.org)
  • Although it is not the only means to maintain a patent airway during general anesthesia, intubation of the trachea provides the most reliable means of oxygenation and ventilation and the greatest degree of protection against regurgitation and pulmonary aspiration. (wikipedia.org)
  • supraglottic
  • The present invention relates generally to a class of medical devices commonly referred to as oral airways and supraglottic airways which are inserted through a patient's mouth and into the patient's pharynx while the patient is undergoing general anesthesia or is undergoing respiratory treatment such as is carried out with cardiopulmonary resuscitation. (google.com)
  • oral airway
  • An oral airway consists of an elongate tubular member having a leading distal end and a proximal end, the leading distal end leading the elongate tubular member as it is inserted into the mouth and pharynx of a patient. (google.de)
  • A flexible tip portion extends distally beyond the opening to aid in insertion of the oral airway into the mouth and pharynx of a patient. (google.de)
  • 3. The oral airway of claim 2 wherein the housing is configured to flex toward the opening about the distal end of the elongate tubular member as the tip abuts tissue as it is inserted into the mouth and pharynx of a patient. (google.de)
  • 4. The oral airway of claim 3 wherein the housing further comprises a pair of spaced ribs extending between an inner surface of a posterior wall and the posterior portion of the distal end of the elongate tubular member, the spaced ribs deflecting to receive the posterior portion of the distal end of the elongate tubular member as the housing is flexed toward the opening. (google.de)
  • 5. The oral airway of claim 3 wherein the housing defines a housing opening corresponding to the tubular member opening, the housing having a plurality of flexible bars covering the housing opening, the flexible bars deflecting as the housing member is flexed toward the opening. (google.de)
  • 6. The oral airway of claim 2 further comprising an elbow attached to the distal end of the elongate tubular member, the elbow defining the opening. (google.de)
  • For most patients, mask ventilation is carried out successfully by insertion of an oral airway and by a variety of physical adjustments, such as extension of the patient's head and elevation of the patient's jaw. (google.com)
  • posterior
  • The main objective of the procedure being enlarging the airway, it has become an alternative to tracheotomy, as here the airway is enlarged by making a wedge shaped resection in the posterior vocal cord and retracting the tissue after freeing the vocal ligament and the vocal muscle from the vocal processes. (wikipedia.org)
  • Anatomy
  • Because of this, the potential for difficulty or complications due to the presence of unusual airway anatomy or other uncontrolled variables is carefully evaluated before undertaking tracheal intubation. (wikipedia.org)
  • anesthesia
  • Oral airways were introduced into the practice of anesthesia and cardiopulmonary resuscitation several decades ago for two basic purposes. (google.com)
  • In this type of thyroplasty, a rectangular portion of the thyroid cartilage is mobilized and pushed towards the medial side using a piece of silastic block of proper shape under local anesthesia. (wikipedia.org)
  • intubation
  • Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for airway support is anticipated. (wikipedia.org)
  • Tracheal intubation can be associated with minor complications such as broken teeth or lacerations of the tissues of the upper airway. (wikipedia.org)
  • Tracheal intubation is indicated in a variety of situations when illness or a medical procedure prevents a person from maintaining a clear airway, breathing, and oxygenating the blood. (wikipedia.org)
  • patient's mouth
  • and C. an airway tube extending from the backplate to a proximal end, the proximal end of the airway tube being disposed outside the patient's mouth when the cuff is at the inserted location, a continuous airway extending from the proximal end of the airway tube to the central aperture of the cuff. (google.es)
  • tissues
  • It is often worse when the infant is on his or her back, because the floppy tissues can fall over the airway opening more easily in this position. (wikipedia.org)
  • lungs
  • When this becomes severe to the point of stupor or coma (defined as a score on the Glasgow Coma Scale of less than 8), dynamic collapse of the extrinsic muscles of the airway can obstruct the airway, impeding the free flow of air into the lungs. (wikipedia.org)
  • Tube
  • More recently, some oral airways have been developed to facilitate blind (not visually directed) placement of an endotracheal tube. (google.com)
  • surgical
  • Also at that time, advances in endoscopic instrumentation had improved to such a degree that direct laryngoscopy had become a viable means to secure the airway by the non-surgical orotracheal route. (wikipedia.org)
  • incomplete
  • This mechanism may be incomplete or delayed in patients complaining of dysphagia and may lead to "penetration" of bolus material into the airway. (springer.com)
  • This leads to inadequate ventilation during exercise and during thermoregulatory panting as well as incomplete protection of the airway during swallowing. (wikipedia.org)
  • cases
  • Kashima Operation should be avoided in cases when a tumour is diffused throughout the thyroid cartilage, because operating in such cases may damage the tumour which may lead to its metastasis. (wikipedia.org)
  • claim
  • 4. A device according to claim 3 , further including bite plate, the bite plate being connected to the airway and drainage tubes, the bite plate being disposed between the patient's teeth when the cuff is at the inserted location. (google.es)
