- PBR is calculated by dividing pulse rate by breathing rate. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- The relationship between PBR and each adverse outcome follows a statistically significant U-shaped nonlinear curve, with risk lowest at intermediate values. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- PBR uses pulse rate rather than heart rate as the numerator because pulse rate represents effective cardiac output reaching the distal limbs, not merely the electrical impulse. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- For mortality, the lowest-risk PBR range is 4.6–6.2; risk rises progressively outside this band in either direction. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- Modern research confirms that a normal PBR falls in the range of approximately 4–5. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- A pre-intervention PBR retains predictive value for downstream outcomes regardless of whether vital signs normalise after treatment. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- PBR simultaneously reflects cardiopulmonary function, blood perfusion, and autonomic nervous system regulation, acting as a composite indicator of heart-lung-brain coordination. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
- The ancient Chinese text Pulse Classic described a ratio-based pulse-breath framework that anticipates modern PBR norms, including recognising 1–2 beats per breath as signalling critical illness. — The use of the raw pulse/breathing rate ratio (PBR) as a predictor of mortality and criticality in the emergency department: a retrospective study
