What is stertor?
Stertor. Stertor is the noise that results from vibration of the pharyngeal tissues (nasopharynx, oropharynx, soft palate) due to significant upper respiratory obstruction and subsequent turbulent airflow downstream in the upper airway. This is a noise heard only on inspiration. This is an “above the clavicle” problem and so ventilation may be...

Unusually loud breathing sounds are often the result of air passing through abnormally narrowed passageways, meeting resistance to airflow because of partial blockage of these regions.

How to help a dog with a partial airway collapse?
Keep your dog cool, quiet, and calm. Anxiety, exertion, and pain can lead to increased movement of air into and out of the lungs, potentially worsening the airflow. Low levels of oxygen in the blood and tissues, and decreased movement of air into and out of the lungs occur with prolonged, severe blockage to airflow; supplemental oxygen is not always critical for sustaining patients with partial airway collapse. In addition closely monitor the effects of sedatives that have been prescribed, as sedatives are known for relaxing the upper airway muscles and worsening the blockage to airflow. Be prepared for emergency treatment if complete obstruction occurs.
What is a strudor in breathing?
Stridor is high-pitched, noisy breathing. The higher-pitched sounds result when relatively rigid tissues vibrate with the passage of air. It often occurs as the result of partial or complete blockage of the nasal passages or voice box (larynx), or collapse of the upper part of the windpipe (known as cervical tracheal collapse).
Why does my dog make a loud noise when he opens his mouth?

What is a stertor in dogs?
The second most common clinical sign associated with upper respiratory disease in dogs, stertor refers to intermittent, yet persistent or continuous snorting, also called stertorous breathing. Paroxysms of stertor, typically called "Reverse Sneezing", characterize rapid, consecutive inspiratory bursts through the nose.

- Your dog's breathing rate and effort will need to be monitored closely. Complete blockage or obstruction could occur after an apparently stable patient is taken home or if continual observation is not feasible. Even with surgical treatment, some degree of obstruction may remain for 7 to 10 days due to postoperative swelling. Care will need to be taken during this time to prot…
