The effect of antipyretic medication on the relationship between heart rate, respiratory rate and temperature in acutely admitted medical patients: A retrospective study

Original Articles, Volume 23, Issue 4, Pages 169– 208 (2024)

Research has shown an association between body temperature, heart rate and respiratory rate. We speculated that antipyretics could influence this. We performed this study with the aim of clarifying the association.We included 1,612 acutely admitted medically ill patients and registered their use of antipyretics. We performed crude and adjusted linear regression analyses. In adjusted analysis,...

Fever increases heart rate and respiratory rate; a prospective observational study of acutely admitted medical patients

Original Articles, Volume 18, Issue 3, Pages 137 – 204 (2019)

Background: The relationship between increase in body temperature, heart rate, and respiratory rate has only been studied in young, healthy subjects.

Aim: To show the changes in heart and respiratory rate associated with fever in acutely admitted medical patients.

Design: A prospective observational cohort study

Methods: Vital parameters from 4,493 patients were retrospectively extracted. Linear and multiple variable regression analysis was used to calculate the change in heart and temperature rate for every degree rise in temperature (i.e. ΔHR/°C and ΔRR/°C) in the entire study group and in those with low (<36.1°C), normal (36.1-38°C) and high (>38°C) body temperatures.

Results: The ΔHR/°C and ΔRR/°C was 7.2±0.4 beats per minute (bpm) and 1.4 ±0.1 (1.2 to 1.62) breaths per minute (bpm). Adjusting for age, oxygen saturation and mean blood pressure, the results were 6.4±0.4 (5.7 to 7.1) bpm and 1.2±0.1 (1.0 to 1.4) bpm. In low, normal and high body temperature the ΔHR/°C were 2.7±1.9, 6.9±1.9 and 7.4±0.9 bpm, respectively; for ΔRR/°C the values were -0.5±0.5, 1.5±0.5 and 2.3±0.3 bpm, respectively.

Conclusions: We only found a modest association between fever and changes in heart rate and respiratory rate.

How well are heart rates measured by pulse oximeters and electronic sphygmomanometers? Practice-based evidence from an observational study of acutely ill medical patients during hospital admission

Original Articles, Volume 18, Issue 3, Pages 137 – 204 (2019)

Background: heart rates generated by pulse oximeters and electronic sphygmomanometers in acutely ill patients may not be the same as those recorded by ECG

Methods: heart rates recorded by an oximeter and an electronic sphygmomanometer were compared with electrocardiogram (ECG) heart rates measured on acutely ill medical patients.

Results: 1010 ECGs were performed on 217 patients while they were in the hospital. The bias between the oximeter and the ECG measured heart rate was -1.37 beats per minute (limits of agreement -22.6 to 19.9 beats per minute), and the bias between the sphygmomanometer and the ECG measured heart rate was -0.14 beats per minute (limits of agreement -22.2 to 21.9 beats per minute). Both devices failed to identify more than half the ECG recordings that awarded 3 NEWS points for heart rate.

Conclusion: Heart rates of acutely ill patients are not reliably measured by pulse oximeter or electronic sphygmomanometers.
