Still, these symptoms of COVID-19 are not conclusive. Newer studies are revealing more symptoms and newer risk factors. However, certain symptoms are more alarming and require emergency medical attention, these include: confusion, troubled breathing, pain in the chest, loss of focus, hypersomnia, and bluish lips/nails [9].
Healthcare as Complex, Entropic and Ethical

In popular culture, the emergency department (ED) has become a symbol of healthcare. It is for this reason that we chose to depict an ED as the opening vignette to this book. Based on a compilation of verbatim reflections of physicians, this vignette is intended to indicate something of the multitude of complex relationships that make the provision healthcare challenging.

At every point in the provision of emergency care, a triage system should be established to ensure the most critical patients are recognised and managed in a timely manner. In addition, management plans should be developed for all potential scenarios, which could involve a large unexpected influx of patients, including mass casualty incidents. A number of different triage and mass casualty systems are in operation and should be contextualised based on the resources available (see Chapter 8.2).

Urgent care continues to be a growing healthcare need across the U.S. and is also helpful in reducing inappropriate use of hospital emergency departments. According to the Urgent Care Association, 400–500 urgent care facilities open annually in the U.S. (Grand View Research 2023). In addition to this growth, demand for virtual urgent care (VUC) grew considerably due to COVID-19 (Figure 5). VUC is convenient and can be safer than sitting in a waiting room, possibly spreading germs and being exposed to other illnesses. VUC also helps reach those in rural areas. In 2018, we started our VUC program, which offers real-time audio video and phone visits, asynchronous messaging, texting, and image uploading. Popular treatment options include COVID-19, flu, cold, ear infection, urinary tract, and skin issues.
AMI in (bi)ventricular pacing – do not discard the ECG

Chest pain is one of the most common symptoms among patients in the emergency department. The diagnosis of AMI relies initially on the patient’s medical history and risk factors, the anamnesis and the 12-lead ECG. However, in the presence of a pacemaker rhythm, the electrocardiographic diagnosis becomes difficult, but not impossible. There is a growing body of literature that suggests that Smith-modified Sgarbossa criteria can be applied for the diagnosis of STEMI in patients with paced rhythms. The Sgarbossa criteria were originally developed for the interpretation of ECGs in chest pain patients with a LBBB, but have been expanded to paced ECGs and optimized by Smith to increase sensitivity and specificity (Figure 1). We present three cases of chest pain patients with, respectively, right ventricular and biventricular pacing and delayed STEMI diagnosis.
Emergency response plan for methane and chlorine with dispersion modelling using CAMEO

An emergency is a condition that is caused by an incident that can cause serious injury, loss of life or extensive damage to plants and property. Emergency conditions arise by powers that are either man-made or naturally occurring [14]. The wastewater is collected at the sewage treatment plant (STP) and transferred to a treatment facility where contaminants are reduced prior to discharge. There is a reduced risk to public health and the environment when these systems operate as intended. However, there may be increased risks in the event of an emergency, as hazardous and flammable gases are stored and used in the plant [15,16]. Domestic sewage contains various sludge. This is digested by a sludge digester, which produces methane (CH4), carbon dioxide (CO2), hydrogen sulphide (H2S), etc. The produced gases are stored in a gas holder. The composition of wastewater digester gas varies, though the primary constituents are methane and carbon dioxide. Trace amounts of nitrogen (N2), oxygen (O2), and hydrogen sulphide may also be present. While the gas compensation will fluctuate depending on temperatures and the process itself, the methane-rich gas (∼60–70% methane) becomes an attractive energy source. A major emergency is created due to the leakage of the stored gas. Since methane has the highest composition (60–75%) compared to all other gases, it is taken for further analysis.
