-Parenchymal disease produces crackles at the end respiration. Differenial diagnoses include cardiogenic pulmonary oedema, [[Pneumonia|pneumonia]], contusions (post-trauma), [[PIE|pulmonary eosinophilic infiltration (PIE)]] and neoplasia.

 '''1) Pleural Effusion'''
-[[Pleural Cavity and Membranes - Pathology|Pleural effusion]] produces muffles heart and lung sounds ventrally. The cat will normally have a short, shallow respiratory pattern. The presence of fluid can be rapidly confirmed using ultrasound.

 '''2) Heart Disease'''
-A cardiac murmur (with or without a gallop) and diffuse crackles across the thorax should be auscultated. An echocardiogram and radiography can be used to confirm the diagnosis of heart disease, however in a very unstable case with cardiac signs it is best to use frusemide as a trial therapy and monitor the response to therapy for diagnosis. Only once the cat has stabilised, or if it is responding poorly to treatment should radiography or echocardiography be performed to confirm the diagnosis.

 '''3) Feline Allergic Airway Disease (Feline Asthma)'''
-A cough, diffuse harsh sounding lung sounds and an expiratory wheeze may be auscultated. The diagnosis of [[Feline Asthma Syndrome|FAAD]] can be confirmed by radiography, which may show a flattened diaphragm, air trapping, rib fractures and a bronchial pattern. However you as a clinician should consider the risk-benefit of this before performing the procedure as the cat may no be able to deal with the procedure with its low oxygen reserve.

-Before steroids are administered it is best '''rule out [[Lymphoma|lymphoma]]''' as the cause of the dyspnoea. The reasons behind this are; that steroids may mask the signs of the neoplasia and, since chemotherapy protocols include steroids, the effectiveness of the chemotherapy is reduced if the cat has been already treated with steroids. In addition, if the respiratory disease is infectious in origin clinical signs may worsen with steroid administration.

 If the cat appears to be going into respiratory arrest then a '''general anaesthetic''' can be used to stabilise the animal, however this should be avoided if possible.

-Whist the cat is in an oxygen cage, a '''thorough history''' should be taken, including the '''duration and progression of the dyspnoea''', any '''previous/current medical problems and medications''', '''husbandry''', '''appetite and thirst''' of the cat and whether they may be a history of '''trauma'''.

 A physical exam should then be performed to establish the location of the respiratory signs:

-Oxygen reserve is generally very low in dyspnoeic cats and you should avoid stressing them if at all possible. This is achieved by '''gentle handling, minimal procedures, and the use of a quiet, dimly-lit room'''.

-On presentation the cat should immediately be placed in an '''oxygen cage'''. This increases the animals oxygen reserve and allows it to relax following the journey to the practise. If an oxygen cage is not available then 'flow-by' oxygen should be supplied in a stress-free manner.
