PURPOSE: Examine changes in oxygen saturation well neonates at altitudes from 4498 to 8150 feet with serial measurements 12 24 hours of age, 36 48 hours, and, if still hospitalized, 60 72 hours. SUBJECTS: Convenience sample newborn infants meeting inclusion criteria normal cardiopulmonary status (centrally pink adequate perfusion) and no respiratory distress (absence grunting, retracting, nasal flaring, or tachypnea-respiration ≤60/minute). DESIGN: Nonexperimental, longitudinal, descriptive study. METHODS: Using Masimo Radical SET monitors the SpO2 values were recorded infant's right upper extremity obtain a preductal measurement then left lower for postductal study intervals. OUTCOME MEASURE: values. RESULTS: The neonates' birth weights ranged 1835 2805 g, 94.3% classified as term 5.7% preterm. At data collection intervals based on life, mean readings 95% 96.67%, 6800 93.91% 95.36%, 7851 91.80% 94.37%, 7890 93.44% 96.10%, 93.69% 96.25%. sites above significantly than those feet. No significant differences noted sleep state season. Significant first second between preterm neonates, higher readings. CONCLUSIONS: Mean levels born are Neonates exhibit "normal" 91% 96% rather expected 97% found sea level. These reference varying can guide clinicians avoid hypoxemia hyperoxia. If routine screening detection critical congenital heart defects is implemented, these results will provide specific additional altitudes, thus preventing unnecessary interventions when 97%.
