What resting SpO2 level typically prompts referral before starting PT?

• A. SpO2 <92%.
• B. SpO2 >98%.
• C. SpO2 94-96% without issues.
• D. SpO2 90% is normal.

Answer: (A)

Resting SpO2 is used as a safety screen before starting physical therapy. When the reading is below 92%, it signals potential hypoxemia that could worsen with activity, so medical clearance or referral is typically needed before proceeding with PT. Normal resting oxygen saturation in healthy individuals is about 95–100%, and values in the mid‑90s without symptoms are generally acceptable to start therapy, but falling below 92% raises enough risk to warrant further evaluation and possible oxygen assessment or alternative plans. In patients with known chronic lung disease who have a different baseline, decisions are guided by their usual saturation, but the common referral threshold remains SpO2 <92%.
