Is stridor an upper airway obstruction?

Stridor is a sign of upper airway obstruction. Generally, an inspiratory stridor suggests airway obstruction above the glottis while an expiratory stridor is indicative of obstruction in the lower trachea. A biphasic stridor suggests a glottic or subglottic lesion. Laryngeal lesions often result in voice changes.

What is the difference between a wheeze and stridor?

What causes crackling?

Crackles (rales) are caused by excessive fluid (secretions) in the airways. It is caused by either an exudate or a transudate. Exudate is due to lung infection e.g pneumonia while transudate such as congestive heart failure. Crackles are high-pitched and discontinuous.

What are the abnormal breath sounds?

Adventitious breath sounds are abnormal sounds that are heard over a patient's lungs and airways. These sounds include abnormal sounds such as fine and coarse crackles (crackles are also called rales), wheezes (sometimes called rhonchi), pleural rubs and stridor.

1. Objects stuck in the airway may be removed with special instruments.
2. A tube may be inserted into the airway (endotracheal tube) to help with breathing.
3. Sometimes an opening is made through the neck into the airway (tracheostomy or cricothyrotomy).
