Expiratory carbon dioxide (CO(2)) monitoring is a valuable tool in the prehospital setting. Recent reports of misplaced endotracheal tubes in the prehospital setting make it important to ensure that tube placement is verified by CO(2) monitoring. ⋯ This article covers the terminology, physiology, technology and clinical applications of CO(2) monitoring. Monitoring of cardiac output and the efficiency of cardiopulmonary resuscitation are described and the article also highlights the importance of CO(2) monitoring in patients with severe head trauma as well as restrictive and obstructive pulmonary disorders.

Due to demographic changes in the population of industrial nations the number of elderly patients undergoing elective or emergency procedures will rise significantly in the coming years. Anesthesia for geriatric patients is challenging for the anesthesiologist in many ways: with increasing age numerous physiological changes occur which all lead to a subsequent reduction of physical performance and compensatory capacity of the organism, in many cases additionally aggravated by chronic illness. ⋯ Part 1 of this continuous education article covers the influence of age on organ functions and describes typical comorbidities which are of high relevance for the perioperative care of geriatric patients. The special features of anesthetic agents and anesthesia management in the elderly will be presented in part 2.

[Nutrition and fluid management in palliative medicine: do food and drink keep body and soul together?].
Induction, implementation and continuation of an invasive nutrition or fluid administration in patients with advanced, life-limiting illnesses is an often controversial but also very emotionally discussed topic. This article summarizes the current state of knowledge based mainly on the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines and is intended as a simple guide for clinical practice. ⋯ Patients in the final stage of a disease rarely suffer from hunger or thirst. In this phase of the disease other things, such as monitoring of patients and relatives play a much more important role.

An increase in ethical conflicts is being observed in the modern intensive care setting, as more complex therapeutic strategies are available and the treatment of old and very old patients is integrated into the clinical routine due to changes in medical options and social epidemiology. Physicians, nurses and families need ethical support to come to a decision about medical treatment when value conflicts are involved. ⋯ The increase of the incidence of ethical conflicts in the intensive care setting may impact ethics consultations which help the integration of ethical principles into the clinical practice.

Obstructive sleep apnea (OSA) can affect all ages from infants to adults. The clinical pathology is initially age-dependent and symptoms first become comparable to those in adults during adolescence. ⋯ Crucial for anesthesia is a presumptive diagnosis in order to consider OSA for the forthcoming strategy. Safety aspects in the treatment of OSA children are especially related to the perioperative securing of the airway and a sufficiently long monitoring of respiratory functions.
