Emphysema. Collateral ventilation is a back-up system of alveolar ventilation that can bypass the normal route of airflow when airways are restricted or obstructed. The pathways involved include those between adjacent alveoli (pores of Kohn), between bronchioles and alveoli (canals of Lambert), and those between bronchioles (channels of Martin).
The spirometry test is performed using a device called a spirometer, [2] which comes in several different varieties. Most spirometers display the following graphs, called spirograms: a volume-time curve, showing volume (litres) along the Y-axis and time (seconds) along the X-axis
Airway obstruction is a blockage of respiration in the airway that hinders the free flow of air. Airway obstructions can occur either in the upper airway or lower airway. The upper airway consists of the nose, throat, and larynx. The lower airway comprises the trachea, bronchi, and bronchioles. [1] [page needed]
This can lead to parts of the lung having a honeycomb-like appearance. The extrinsic causes result in lung restriction, impaired ventilatory function, and even respiratory failure due to the diseases that effect the lungs ability to create a change in lung volumes during respiration due to the diseases of the systems stated above.

Since not all dogs do well with the normal pain meds (like aspirin, meloxicam, etc.), you can try CBD oil. You will have to get it from the internet and follow the dosing schedule suggested by the ...
Measuring pulmonary mechanics assesses the ability of the lungs to move huge volumes of air quickly through the airways to identify airway obstruction. [ citation needed ] The measurements taken by the spirometry device are used to generate a pneumotachograph that can help to assess lung conditions such as: asthma, pulmonary fibrosis, cystic ...
Oftentimes, when dogs undergo a surgery, there is one person who will take care of the dog, help the dog get up, take the dog out on leashed walks, provide mental enrichment, etc.
