TYPE OF RESPIRATION

• When respiratory muscles and the diaphragm are involved in respiratory movements it is called costoabdominal respiration which noticed in both dog and cat
• Pendulous respiration occurs in diaphargmatic rupture occurs here bulging of the abdomen is absent due to loss of diaphargams function and also the there is decrease in abdominal circumference
• Pseudopendulous occurs in severe dyspnea here it is a forced inspiration as little air is drawn and flattening of diapragm is absent.
• At the end of expiration when abdominal pressure is exerted on diaphragm it is abdominal type of respiration.
• Inspiration is active and expiration is passive.
• Inspiratory dyspnea occurs when there is n arrowing in the respiratory passages cranial to the thoracic inlet showing costal type of respiration (Watch video)
• Expiratory dyspnea occur when there is l oss of elasticity of the lungs as well as loss of flexibility of the thorax which is assisted by abdominal pressure which inturn displaces the diaphragm resulting in slow incomplete expiration
