The tongue is the most common cause of upper airway obstruction, a situation seen most often in patients who are comatose or who have suffered cardiopulmonary arrest. Other common causes of upper airway obstruction include edema of the oropharynx and larynx, trauma, foreign body, and infection.
What are some common causes of airway obstruction in the dental office?
Causes: Airway obstruction in the dental office is usually caused by foreign objects dropped into the Oropharynx. In the unconscious patient, obstruction is usually caused by the tongue falling back against the posterior wall of the pharynx.
What are the common causes of upper airway obstruction pals?
The three most common causes of upper airway obstruction are infection (croup, epiglottitis, RSV, etc…), airway swelling (anaphylaxis), and foreign body airway obstruction (FBAO). Other factors can affect upper airway patency as well.
What is a cause of intrinsic airway obstruction?
Intrinsic causes of airway obstruction include laryngeal cysts, webs, and atresia. The spectrum of disease due to intrinsic compression has been called congenital high airway obstruction syndrome (CHAOS) (Hedrick et al., 1994; Lim et al., 2003). Airway obstruction may be fatal in utero.What is the most common cause of acute respiratory obstruction in children?
The most common cause of infective upper airway obstruction in children is viral laryngotracheobronchitis, or croup, which is usually a mild and self-limiting illness, but management with corticosteroids may still be necessary.
What is the most common airway obstruction in an infant?
Croup is the most common cause of airway obstruction in young children (11).
How do you manage hypoglycemia in the dental office?
Every dental office should have a protocol for managing hypoglycemia in conscious and unconscious patients. Having snack foods or oral glucose tablets or gels available, especially in practices where a large number of surgical procedures are performed, is also prudent.
What is a mechanical airway obstruction?
One of the most common airway obstructions is the one that results from an extrinsic cause to the airway–food, blood or vomit. Any solid object can work as a foreign body and cause an airway obstruction–mechanical obstruction. Evaluation and control of the airway are carried out through quick and simple procedures.What causes bronchial obstruction?
The cause of the obstruction may lie wholly within the lumen of a bronchus, as in the case of an intrabronchial foreign body; it may originate within the bronchial wall, as in the case of a bronchogenic carcinoma, or it may lie entirely outside the wall of the bronchus in the peribronchial or adjacent tissue, as in the …
What causes narrowing of airways?Airway stenosis (airway narrowing) is a narrowing of the airway caused by malignant and benign tumors, congenital abnormalities, airway injury, endotracheal intubation, tracheostomy, or autoimmune diseases – though sometimes there’s no obvious cause.
Article first time published onIs asthma an upper airway obstruction?
Asthma and chronic obstructive pulmonary disease (COPD) are diseases characterised by lower airway obstruction, with breathlessness as a frequent symptom.
When does stridor occur?
Less musical sounding than a wheeze, stridor is a high-pitched, turbulent sound that can happen when a child inhales or exhales. Stridor usually indicates an obstruction or narrowing in the upper airway, outside of the chest cavity.
Which of the following conditions is considered an airway emergency and can cause acute airway obstruction?
Acute airway obstruction occurs when there is a blockage in the airway, which can partially or totally prevent air from reaching the lungs. Swallowing or inhaling a foreign object, an allergic reaction, asthma and even certain types of infections can cause the airway to become obstructed.
Can infection cause airway obstruction?
Fortunately, these are mostly due to self-limiting viral laryngotracheobronchitis (LTB), but there is also a group of bacterial infections (e.g., epiglottitis, bacterial tracheitis, diphtheria, retropharyngeal abscess, and peritonsillar abscess) that can occasionally cause significant obstruction.
Can a tooth infection make your blood sugar go up?
An infection such as periodontitis may also cause your blood sugar level to rise, which in turn makes your diabetes more difficult to control. Preventing and treating periodontitis with regular dental cleanings can help improve blood sugar control.
What are the steps for treating a patient experiencing hypoglycemia symptoms?
If you have symptoms of hypoglycemia, do the following: Eat or drink 15 to 20 grams of fast-acting carbohydrates. These are sugary foods without protein or fat that are easily converted to sugar in the body. Try glucose tablets or gel, fruit juice, regular — not diet — soft drinks, honey, and sugary candy.
How often should a diabetic see a dentist?
Because of the increased risk of oral health problems, people with diabetes should visit their dentists more regularly. Instead of visiting dentists twice per year, people who have diabetes should visit a dentist once every three months.
What causes an airway obstruction in a newborn?
Children born with congenital craniofacial, pharyngeal, or laryngeal abnormalities are at an increased risk for severe upper airway obstruction (UAO). Severe UAO can be caused by a variety of disease processes, including Pierre Robin Sequence (PRS), laryngomalacia, and vocal cord (VC) paralysis.
Which anatomic feature may cause more frequent airway obstruction in infants and children than in adults?
Retroglossal obstruction occurs in approximately half of obstructions in infants, compared with adults where the vast majority of intrinsic airway obstruction occurs at the level of the soft palate [4,5]. Larger tonsils and adenoids — Children more commonly have larger tonsils and adenoids than adults.
What are signs of upper airway obstruction in a child?
- choking or gagging.
- sudden violent coughing.
- vomiting.
- noisy breathing or wheezing.
- struggling to breathe.
- turning blue.
What causes airway obstruction in COPD?
Causes of airway obstruction include: Emphysema. This lung disease causes destruction of the fragile walls and elastic fibers of the alveoli. Small airways collapse when you exhale, impairing airflow out of your lungs.
How does airway obstruction affect breathing?
Airway obstruction causes increased resistance to airflow and decreased expiratory flow rates. These changes lead to a decreased ability to expel air and may result in hyperinflation.
What are the main signs of a complete airway obstruction?
- Can’t cry, talk, breathe, or cough.
- May grasp throat.
- May become severely anxious or agitated.
- May turn blue or dusky in colour.
- May pass out.
How do I widen my airway?
Laryngotracheal (luh-ring-go-TRAY-key-ul) reconstruction surgery widens your windpipe (trachea) to make breathing easier. Laryngotracheal reconstruction involves inserting a small piece of cartilage — stiff connective tissue found in many areas of your body — into the narrowed section of the windpipe to make it wider.

Can pneumonia cause airway obstruction?
Infections such as the flu and pneumonia are major contributors to airway obstructions, especially in the elderly and children under the age of 4. When a person has a second medical condition, such as asthma or COPD, infections pose a more urgent risk to the airway.
What causes upper airway wheeze?
Expiratory wheezing caused by the narrowing of a person’s trachea and, possibly, mainstem bronchi. As expiratory air rushes out through the narrowed trachea or mainstem bronchi, the wheezing sound is created.
What is the difference between wheezing and stridor?
Stridor is a higher-pitched noisy that occurs with obstruction in or just below the voice box. Determination of whether stridor occurs during inspiration, expiration, or both helps to define the level of obstruction. Wheezing is a high-pitched noise that occurs during expiration.
What disease causes stridor?
With infants, stridor usually indicates a congenital disorder (problem that your child is born with), including laryngomalacia, vocal cord paralysis or subglottic stenosis. If your toddler or older child develops stridor, it may occur as a result of an infection such as croup or papillomatosis.
Is stridor on inhale or exhale?
Stridor is a high-pitched sound heard best when your child is breathing in (inhaling). It can also be heard when your child is breathing out (exhaling). Noisy breathing, or stridor, is most often a symptom of a throat or airway problem.
