NettetRespiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration, by which the R-R interval on an ECG is shortened during inspiration and prolonged … 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.

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.

Positive End-Expiratory Pressure (PEEP) is the maintenance of positive pressure (above atmospheric) at the airway opening at the end of expiration. PEEP acts to distend distal alveoli, assuming there is no airway obstruction.
