Abstract
In recent years, there have been increasing opportunities for dental clinics to examine medically compromised or/and very elderly patients, and the importance of systemic management is increasing in order to realise safe dental treatment. It may be misunderstood that advanced knowledge and skills are required to manage the general condition of patients, but in fact what is essential in the general management of patients undergoing dental treatment is the basic knowledge required to understand the condition of patients undergoing dental treatment, to recognise and respond to changes and abnormalities in their general condition, and to share this knowledge with all staff involved in dental care. Biological information such as vital signs (blood pressure, pulse, respiration, temperature) and arterial blood oxygen saturation (SpO2) are essential for understanding the patient's general condition. The early detection and responding to abnormalities based on this biological information may lead to safe dental care. In addition, the incidence of systemic complications during dental treatment is expected to increase in a super-aged society. Appropriate responses to systemic contingencies such as the vasovagal reflex and hyperventilation syndrome, which may occur during dental treatment, are also essential for safe dental treatment. This article describes the normal values and correct measurement methods of vital signs and other biological information essential for understanding the patient's general condition, and also describes the typical systemic contingencies that occur during dental treatment and how to deal with them.
