Which of the following is false as physiological change in pregnancy?
In Pregnancy, diaphragm pushed upwards by enlarged Uterus thus reducing Residual volume of lungs. Diaphragm is elevated by around 4cm subcostal angle increases from 68o to 104o. Transverse diameterof chest increases by 2 cm Changes in Respiratory System Parameters Non pregnant Pregnancy near term Change Respiratory rate/min 15 15 unaffected Vital capacity (mL) 3200 3300 Almost unaltered Tidal volume (mL) 500 700 + 40% Residual volume (mL) 965 765 - 20% Inspiration capacity (IC) 2500 2650 + 10% Minute ventilation 7.5 L/min 10.5 L/min + 40% Total lung capacity (mL) 4200 4000 - 5%( almost unchanged)
Increase cardiac output
Increase total protein
Increase residual volume
Increase GFR
