From Birth to Age One Physical Milestones

o 0-4 months: 50-300 ml/day urine productiono 0-7 years: PMI (point of maximum impulse of heart) located at 3rd or 4th

intercostal space, just left of midclavicular line o 0-2 years: respiration rate 24 to 34 respirations per minute o 0-1 years: pulse rate 135 ± 3.1 o 0-1 years: blood pressure 90 ± 25 systolic, 61 ± 19 diastolic o 0-1 years: pulse 70-180, respiration 30-40 o 0-1 years: temperature : 99.6F rectal, 98.6F oral, 97.4F axillary o 0-1 years: PaO2 85-100, PaCO2 35-45 o 0-15 months: eliminates urine & feces automatically; may need up to 30 diapers a
