The normal arterial oxygen partial pressure (PaO2) for a 70-year-old man typically ranges from 75 to 100 mmHg. However, this value can vary based on individual health status, altitude, and respiratory conditions. It's important to consider that older adults may have slightly lower PaO2 levels due to age-related changes in lung function. Always consult healthcare professionals for accurate assessments based on individual circumstances.
