IJOA 16-00229 Appendix Supplementary Figure 1: Heart rate (beats/min) ranges used to define on obstetric early warning charts. Each vertical line ‘normality’ represents a single vital signs chart, ordered on basis of the lowest heart rate value in the chart’s normal range. Beats/min Charts 1-120  Supplementary Figure 2: Respiratory rate (breaths/min) ranges used to define on obstetric early warning charts. Each vertical line ‘normality’ represents a single vital signs chart, ordered on basis of the lowest respiratory rate value in the chart’s normal range. Breaths/min Charts 1-120  Supplementary Figure 3: Systolic blood pressure (mmHg) ranges used to define on obstetric early warning charts. Each vertical ‘normality’ line represents a single vital signs chart, ordered on basis of the lowest systolic blood pressure value in the chart’s normal range. mmHg Charts 1-120  Supplementary Figure 4: Diastolic blood pressure (mmHg) ranges used to define on obstetric early warning charts. Each vertical ‘normality’ line represents a single vital signs chart, ordered on basis of the lowest diastolic blood pressure value in the chart’s normal range. mmHg
