Chronic Bronchitis

Is quite common for cats to present to veterinary clinics with a chronic cough or wheeze. The problem may be constant or just recur from time to time, and can range from mild to severe. Clinically the disease may resemble human asthma, but the term feline asthma can be misleading as there are a number of different possible causes. Here we look at what those underlying causes can be, and the different forms of treatment available to affected cats. Wink

To return to the comparison with human asthma, when trying to understand the underlying causes it is important to differentiate between asthma (constriction of the bronchi), chronic bronchitis (oversecretion of mucus with a chronic cough) and COPD (chronic obstructive pulmonary disease). Asthma is reversible bronchial constriction caused by eosinophil cells, whereas COPD ellis university bronchial constriction involving neutrophil cells.

Spacer Devices

A spacer device consists of a chamber into which the aerosol drug is released at one end, with a mask at the other end which fits snugly over the cats mouth and nose. Human baby spacer devices (e.g. Babyhaler) can be easily adapted for cats. Alternatively, veterinary spacers specifically designed for cats are now on the market (e.g. Aerokat). The spacer should be held over the cats nose and mouth for about 30 seconds to ensure complete delivery of the drugs. It should be remembered that aerosol steroid therapy can take up to 2 weeks to reach full effect, and if the cat has been on oral steroids previously, these should be phased out slowly during these initial 2 weeks. Some of the matter found here that is pertaining to Bronchitis seems to be quite obvious. You may be surprised how come you never knew about it before!

Pulmonary Edema

Often due to severe heart disease.Infectious bronchitis. This can be due to bacteria, viruses or parasites.Pleural disease. Filling of the space between the lung and the chest wall with air or an effusion.Cancer. This can be a primary lung tumor or metastatic spread.Potassium bromide induced respiratory disease. A side effect from an anti-epileptic drug.Idiopathic pulmonary fibrosis. Responds poorly to treatment.Pulmonary thromboembolus. Lodging of a clot in a respiratory blood vessel causing sudden onset breathing difficulty.Pulmonary hypertension. Usually secondary to other heart or respiratory disease. Self-praise is no praise. So we don't want to praise ourselves on the effort put in writing on Bronchitis. instead, we would like to hear your praise after reading it!

Cats usually present with one or all the following signs: CoughingWheezingDifficulty breathing A minority of cases will have the classic human status asthmaticus, rapid onset breathing difficulty due to severe narrowing of the bronchi. Cats tend to be middle aged or older, and Siamese cats may be more prone than other breeds.


The Seretide Evohaler is useful for cats requiring know the signs of a bronchial cough therapy. It contains salbutamol and fluticasone, a combination allowing minimal dosing frequency. The presentation of an article on Bronchitis plays an important role in getting the reader interested in reading it. This is the reason for this presentation, which has gotten you interested in reading it! Very Happy.


Lung Biopsy

This is an invasive procedure that carries a significant risk to the patient. It is only indicated where diffuse cancer or extensive fibrosis is suspected, or in severe disease that responds poorly to treatment. We find great potential in Infectious Bronchitis. This is the reason we have used this opportunity to let you learn the potential that ways to detect persistent bronchitis.

Remove or Avoid Airway Irritants

The most obvious one is ensuring the cat has no contact with cigarette smoke, and purchasing dust free cat litter. It is always better to have compositions with as little corrections in it as possible. This is why we have written this composition on Bronchitis with no corrections for the reader to be more interested in reading it.

Bronchodilator drugs used in inhalers include Salbutamol and Salmeterol. Salbutamol is very fast acting and therefore useful in a crisis caused by spasm of the bronchi. However, it only lasts for about 30 minutes and is therefore unsuitable for chronic therapy as frequent dosing is required. Salmeterol on the other hand is longer acting, and lasts for about 12 hours so twice daily dosing is possible. Salmeterol is better for long term control of mild to moderate asthma while Salbutamol is better for relief of acute bronchospasm. We did not write too elaborate an article on Infectious Bronchitis as it would be then difficult for the common man to read it. We have written this article in such a way that everyone will be able to read and understand it!

Aerosol therapy has the advantage that the maximum concentration of drug is delivered to the target site. This means that lower overall doses can be used, and the cat is less likely to suffer the negative side effects of steroids. Various inhalers can be used in both cats and dogs, but they tend to be designed for humans. As a result, higher doses are given compared with human medicine, as humans can be instructed to breathe deeply whereas cats will breathe normally at best. It is rather interesting to note that people like reading about Bronchitis if they are presented in an easy and clear way. The presentation of an article too is important for one to entice people to read it!

Glucocorticoid drugs (steroids) used in inhalers include Beclometasone, Fluticasone and Budesonide. Beclometasone is cheap, but is rapidly absorbed into the bloodstream when you want it to hang around in the area where it applied. Fluticasone is more expensive, but tends to stay where you want it to. Budesonide is relatively inexpensive and though it is easily absorbed into the bloodstream, it tends to be removed the first time it goes through the liver. Reading all this about Bronchitis is sure to help you get a better understanding of Bronchitis. So make full use of the information we have provided here.



  • Radiography The next test performed is usually thoracic radiography.
  • This is best performed under general anesthetic so there is lee chance for motion blur, though in acute situations this is not possible.
  • This is where the most meaningful information can be gained.
  • Do not judge a book by its cover; so don't just scan through this matter on Bronchitis. read it thoroughly to judge its value and importance.



The Differentials

There are a large number of possible diagnoses when a cat first presents with coughing or breathing difficulty. Here are some of the more important ones: Thinking of what to do upon reading this article on Chronic Bronchitis? Well you can very well use the information constructively by imparting it to others. Surprised.

  • Treatment The aims of treatment are as follows. 1.
  • Eliminate any suspected infectious agents.
  • This may be a sufficiently long course of antibiotics if bacterial infection is suspected, or a wormer such as fenbendazole if lungworm is suspected.
  • Responsibility is what makes a person.
  • So we felt it our responsibility to elaborate more on Infectious Bronchitis so that not only us, but everyone knew more about it!



Removal or Avoidance of Potential Allergens

House dust mite allergy must be excluded by spraying the house with an acaricidal product. 4. Chronic therapy for the underlying condition. For long term treatment of cats with feline asthma, a combination of steroids and bronchodilators are a popular choice. Steroids reduce the inflammation and lower mucus production, and can limit long term consequences such as fibrosis. Bronchodilators are most useful when there is airway spasm. Traditionally, medication has been given orally via tablets, but over the last few years, metered dose inhalers such as the ones used for human asthma have come on the market. We were actually wondering how to get about to writing about Infectious Bronchitis. However once we started writing, the words just seemed to flow continuously! Rolling Eyes

Diagnosis 1. Clinical examination The first step in the diagnostic protocol is a thorough clinical examination by a veterinarian. This should localize the origin of the disease to the upper airways, lower airways or pleural space. If the cat is found to have pleural disease, a needle may be inserted straight away to remove either air or a sample of the effusion for both diagnosis and short term treatment bronchitis respiratory therapy. Failure is the stepping stone to success. So if you do fail to understand this article on Infectious Bronchitis, don't fret. Read it again a few times, and you are sure to finally get its meaning.

Treatment Lifelong?

Generally yes. Doses can often be reduced gradually once clinical remission has been achieved. As with many chronic conditions, complete control might not always be possible and an acceptable quality of life is the main aim of the treatment.
