Clinical Workflows Supported by Patient Care Device Data
Published in John R. Zaleski, Clinical Surveillance, 2020
Systolic blood pressure, BPsys, referenced in Equation 5.14 may be obtained through a non-invasive blood pressure cuff measurement. Pulse or heart rate can also be obtained through normal bedside measurements such as pulse oximetry monitoring. In both of these instances, the physiological variables represent standard patient care device parameters that can be communicated directly from the bedside to end-point electronic medical record systems or other types of clinical information systems. Studies have also shown that sudden onset cardiac arrest and unexpected (unplanned) transfers from lower acuity in-hospital settings to the intensive care unit have been preceded by instabilities reflected through physiologic measurements [120].

In arrhythmia the heartbeats or rhythms become abnormal. Arrhythmia arises mainly owing to the heart related electrical impulses. If the electrical impulses do not work properly, the heart will become unable to coordinate its beats resulting in irregular rhythms. These impulses can be too fast, too slow, or too erratic causing the heart not to pump blood systematically (About Arrhythmia, 2016). If the heart does not pump blood effectively, the organs might be damaged or completely shut down. Arrhythmias have various types, e.g., tachycardia, bradycardia, and a trial fibrillation. The average heart rate is normally between 60 to 100 beats per minute under normal physical state (All About Heart Rate (Pulse), 2015). Tachycardia refers to a heart rate which is much faster, at or faster than 100 bpm (beats per minute), than the average heart rate (Tachycardia: Fast Heart Rate, 2016). Bradycardia refers to heart rate that is slower that 60 bpm (Bradycardia: Slow Heart Rate, 2016). Atrial fibrillation, also called AFib or AF, is a heartbeat which is irregular/flutters (Atrial Fibrillation, 2016). Arrhythmia occurs if the heart’s natural pacemaker develops an abnormal rhythm or rate, the conduction pathway is disrupted, or if another part takes on the role as the pacemaker.

After being dried, the baby should be placed in a clean dry warm towel under a radiant heater. the heart rate should be determined by listening to the heart with a stethoscope. If the baby is not breathing, the breathing is irregular, the heart rate is less than 100 or begins to slow, active resuscitation with mask ventilation should be started immediand the paediatrician called.

To our knowledge, this is the first study to suggest that the changes in symptoms and QoL after EC, are correlated with hemodynamic changes in CO and RR variability. In this study, patients who maintained SR experienced an average increase in CO by 23%. Furthermore, the CABANA trial demonstrated that catheter ablation of AF, compared to drug therapy, resulted in improved QoL as measured by AFEQT [25]. Interestingly, we only found mild correlations between symptom improvement and changes in HR and BP in this relatively small study and the strongest physiological correlates were CO and RR variability. Frykman et al. demonstrated that AF episodes that caused patients to seek care had a higher ventricular rate [26], but in contrast, Clark et al. have shown that rhythm irregularity in itself, regardless of heart rate, causes adverse hemodynamic consequences [27].

Height and weight were measured with a stadiometer and scale (Satorius Corp., Bohemia, NY, USA). Urine-specific gravity was measured using a handheld refractometer (Atago, Bellevue, WA). Nude body weight was measured pre- and post-exercise after towel drying. Heart rate was measured using a standard heart rate monitor (Polar Electro, Bethpage, NY, USA). Approximately 90 minutes prior to experimental testing, each subject swallowed a telemetry pill (HQ Inc., Palmetto, FL, USA) for the measurement of core temperature. This approach provides a valid measure of core temperature, particularly when drinking is prohibited [29]. Mean skin temperature was measured as the weighted average of four thermochron iButtons (Maxim Integrated, San Jose, CA, USA) using the following equation: 0.3 · (chest + triceps) + 0.2 · (quadriceps + calf) [30].

As with all real-world studies, this study is not without limitations. The research presented relied on a single sample of doctors in their first postgraduate training year at a large UK teaching hospital, which may have implications for the generalisability of the findings. However, participants were selected at random and few of the doctors approached declined to participate so the effects of sampling bias were minimized as far as possible. In addition, heart rate is not a perfect correlate of psychological stress and will be affected by other factors, most notably physical activity. While metabolic changes in heart rate were controlled for by continuously recording and accounting for the effects of physical activity during analysis, some variation in heart rate will inevitably reflect non-stress processes. In future studies, it would be preferable to supplement such physiological measures with self-reports of perceived stress.
