Sleep-related breathing disorders have been associated with increased perioperative morbidity and mortality. The respective patients are at risk during two independent periods. Besides an early period, characterised by the influence of anaesthetics, patients are at risk also during a late period, which is characterised by nocturnal desaturation and disturbances of the cardiovascular system, caused by interference with the sleep architecture, especially of the REM sleep. To assure a safe perioperative management, a close monitoring (O2 saturation and pCO2) and the option for non-invasive ventilation have to be guaranteed.

The initiation of and weaning from mechanical ventilation with extubation cause significant changes in intrathoracic pressures and have profound consequences for the cardiovascular function. However, in spite of the known pathophysiological relationships, frequently little attention is paid to the cardiovascular situation during the weaning period. The currently available guidelines concerning weaning and extubation/reintubation are based on only limited evidence and are thus rather general. ⋯ On the contrary, many intensive care patients have subclinical or undiagnosed cardiac disease, and cardiovascular compensation mechanisms are frequently hampered by the underlying critical illness. Therefore, in a significant proportion of patients, weaning and extubation attempts fail due to the patient's limited cardiovascular reserves. This review summarises the relevant information for a successful weaning and extubation with special respect to the cardiovascular function.

Palliative care should be part of respiratory medicine for two reasons: first, many respiratory diseases--besides thoracic tumours--need palliative care in the late stages of the disease. Second, dyspnoea is a common symptom in advanced, primary extrapulmonary diseases and the knowledge of respiratory specialists can be beneficial in the treatment of this symptom. In this paper we describe frequent symptoms of advanced pulmonary diseases and their treatment. Moreover, we focus on the structure of palliative care in Germany.
