Figure 1From: Effect of external airflow resistive load on postural and exercise-associated cardiovascular and pulmonary responses in pregnancy: a case control studyMean values for measured cardiovascular variables of pregnant controls (PREG-CON) and trials (PREG-EARL) and non-pregnant controls (NPREG-CON) and trials (NPREG-EARL). Values are mean (n=32; 16 pregnant and 16 non-pregnant subjects). (A) SBP = systolic blood pressure, (B) DBP = diastolic blood pressure, (C) MAP = mean arterial pressure, (D) HR = heart rate, (E) SV = stroke volume, (F) CO = cardiac output.Back to article page
