Residual Volume

Also written as RV.

Tidal volume rises about 40% and minute ventilation about 40%; residual volume falls; vital capacity and FEV1 are unchanged.

What our notes say

• Tidal volume rises about 40% and minute ventilation about 40%; residual volume falls; vital capacity and FEV1 are unchanged. (Physiological changes in pregnancy)
• after a maximal inspiration, and (2) residual volume (RV), defined as alveolar pressure minus pleural pressure) is\n25 (Harrisons Pulmonary and Critical Care Medicine)
• Left ventricular failure may mimic the\nincreased airway resistance and may show increased total wheezing of asthma, but basilar crackles are present in\nlung capacity and residual volume. (Harrisons Pulmonary and Critical Care Medicine)
• Progressive reduction in carbon monoxide diffusing capacity, vital capacity and total lung capacity, with normal residual volume.\nCompliance is decreased and lung recoil pressure increased (8.OCCUPATIONAL AND ENVIRONMENTAL LUNG DISEASES MBCHB 2019-2-1)
• Residual volume and total lung capacity need body plethysmography or gas dilution. (Internal Medicine Respiratory CAT 1: 30 MCQs and 5 short answer questions)
