Vitals Statistics

See how a reading can be “normal” on the surface yet still signal risk, like masked hypertension affecting 10 to 15% of people and pulse pressure over 60 mmHg raising CVD events risk by 1.6 times. This Vitals page ties blood pressure and oxygen numbers to action ready thresholds such as MAP 65 to 110 for ICU care and fever and SpO2 cutoffs that help you spot when home trends should become urgent.

Statistics that fail independent corroboration are excluded.

Vitals statistics don’t just classify health they reveal patterns that show up as blood pressure shifts, oxygen dips, and breathing rates that change outcomes fast. For example, pulse pressure above 60 predicts cardiovascular events with a relative risk of 1.6, while non dipping blood pressure can double CVD risk. Let’s map the “normal” ranges alongside the thresholds that trigger urgent clinical decisions across the full dataset.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
