NettetPulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure and pulse wave amplitude during inspiration.The normal fall in pressure is less than 10 mmHg.When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus. Pulsus paradoxus is not related to … NettetTidal volume (TV) is the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters.Expiratory reserve volume (ERV) is the amount of air you can forcefully exhale past a normal tidal expiration, up to 1200 milliliters for men.Inspiratory reserve volume (IRV) is produced by a deep inhalation, past a tidal inspiration.

A split S2 is a finding upon auscultation of the S2 heart sound. It is caused when the closure of the aortic valve (A2) and the closure of the pulmonary valve (P2) are not synchronized during inspiration. The second heart sound (S2) is caused by the closure of the aortic and pulmonic valves, which causes vibration of the valve leaflets and the adjacent structures. The aortic v… NettetDuring inspiration: The second sound (S2) is made of two component sounds: Aortic valve closure (A2) which happens first. Pulmonic valve closure (P2) which happens second. A2 is heard widely all over the chest. So when you hear 'S2' at the mitral area, you are really hearing A2. Normally, P2 is soft and only heard at the pulmonic region (left ...

Nettet18. aug. 2016 · During inspiration, an increased volume of blood returns to the heart, reducing vagal tone and increasing sinus rate. During expiration, venous return decreases, vagal tone increases, and sinus rate slows. Conditions unrelated to respiration may also produce sinus arrhythmia.
