A Detailed Review of Critical Care Considerations for the Pregnant Cardiac Patient
2021, Canadian Journal of CardiologyCitation Excerpt :Difficult airway algorithms exist specific to obstetrical patients.23 Maternal O2 consumption and CO2 production are 20%-35% higher compared with the nonpregnant state.17,24,25 Maternal minute ventilation is increased by approximately 40%, due to the stimulant effect of the increased CO2 production and elevated progesterone levels.26

2014, Best Practice and Research: Clinical Obstetrics and GynaecologyCitation Excerpt :Specific airway management protocols for pregnant women are beyond the scope of this chapter; however, excellent resources are available [50,52]. During pregnancy, functional residual capacity reduces and oxygen consumption increases, which results in a reduction in oxygen reserve [46,53–55]. Reduced oxygen reserve contributes to the rapid desaturation seen during pregnancy.
Longitudinal metabolic changes in the hippocampus and thalamus of the maternal brain revealed by proton magnetic resonance spectroscopy
2013, Neuroscience LettersCitation Excerpt :Hyperventilation may cause an increase in the Lac concentration [8]. Therefore, increased Lac levels in the thalamus might be related to hyperventilation during pregnancy due to high levels of oxygen consumption [22]. One limitation to the current study is the lack of absolute concentration measurements.
