artificial airway

Etymology: L, artificiosum, skillfully made
a plastic or rubber device that can be inserted into the upper or lower respiratory tract to facilitate ventilation or the removal of secretions.

airway

1. the passage by which air enters and leaves the lungs.
2. a mechanical device used for securing unobstructed respiration during general anesthesia or other occasions in which the patient is not ventilating or exchanging gases properly. Includes an endotracheal tube and a tracheostomy tube.

artificial airway
endotracheal or tracheostomy tubes.
airway obstruction
in the unanesthetized animal is usually caused by vomitus or laryngeal spasm due to foreign material in the larynx. In the nonintubated anesthetized animal, it is caused by caudal displacement of the tongue and epiglottis, accumulation of mucus, saliva and blood in the pharynx or laryngeal spasm resulting from that accumulation. In the intubated animal, faulty placement or functioning of the endotracheal tube or kinking of it can cause obstruction of the airway. The signs of obstruction are deep, asphyxial respirations, struggling and great agitation in the conscious animal. Deeply anesthetized animals simply show a decline in respiratory efficiency.
airway reflexes
aid in the removal of secretions and foreign material. See also cough, sneeze.
airway resistance
the resistance to airflow through the respiratory tree and any addition to the airway, such as the endotracheal tube and connectors in a closed circuit anesthetic machine.

We know that patients with artificial airways and patients who are unconscious are at risk for barotrauma and its complications following HBOT, but there is still a necessity to identify new risk groups in order to lower complication rates.
Other factors, including RLD, immobility, and the complications secondary to the presence of an artificial airway, increase those risks.
Wolf et al treated 30 patients who had an abrupt onset of symptoms (including stridor and dyspnea) who were not given an artificial airway, and all 30 patients fared well.
This requires the caregiver to disconnect the circuit from the patient, interrupting ventilation, disturbing the artificial airway, exposing themselves to infectious ventilator gases, and potentially contaminating the circuit interior.
In the presence of increased resistance of the artificial airway due to obstruction, this driving pressure can be unexpectedly high.
In other words, there are situations in which the artificial airway is a major barrier, and situations in which it is not.
Measuring cardiac output non-invasively with NICO2(TM) requires only the attachment of a single patient use rebreathing circuit to an artificial airway already in place for ventilated patients.
Use your eyes and hands to inspect the artificial airway for signs of compromise or excessive dermal pressure on the surrounding tissue.
The patient may still require ventilatory support and but not require an artificial airway and the associated complications.
This makes the Limb-O circuit markedly lighter than common dual tube circuits thus exerting less "drag" on the patient's artificial airway.
Invasive ventilation has a myriad of complications associated with it--the artificial airway itself; ventilator-associated pneumonia, barotrauma, biotrauma, and airway trauma to name a few.
Even though an x-ray confirms this condition, a patient experiencing respiratory failure must receive an artificial airway immediately.
