Final answer:
The companion document does not detail the relationship between blood glucometry and cardiac arrests, but it discusses cardiac arrest as a severe condition that stops effective blood pumping and references treatment options for arrhythmias.
Step-by-step explanation:
Based on the information provided, the companion document does not specifically address the relationship between blood glucometry and cardiac arrests. However, it is known that cardiac arrest occurs when the heart can no longer pump blood effectively, leading to a severe medical emergency. Those with symptomatic arrhythmias may require urgent treatment such as cardioversion or defibrillation to prevent such outcomes. Furthermore, having a very low blood pressure, as demonstrated by the reading of 70/45, can result in confusion and thirst due to the inadequate circulation of blood. While this can relate to blood sugar levels, the provided reference does not give explicit details concerning glucometry in the context of cardiac arrest.
