Arterial blood gas (ABG) analysis, a core component of critical care monitoring, provides immediate information on the status of the patient’s respiratory system and whether a state of acidosis or…
An imbalance of oxygen delivery and demand with resultant organ dysfunction is the hallmark of critical illness. Measuring oxygen delivery, recognizing tissue hypoperfusion, and monitoring the response to therapeutic interventions…
Acute kidney injury (AKI) is a syndrome that is frequently and commonly observed among hospitalized and especially critically ill patients. The incidence of AKI varies based on the criteria used…
The aim of this chapter is to review the evidence surrounding the use of renal replacement therapy (RRT) in the intensive care unit (ICU) setting. It examines the conventional indications…
Acute kidney injury (AKI) is common in the intensive care unit (ICU) and is associated with poor outcomes. There is evidence that even minor short-term changes in serum creatinine (i.e.,…
In 1616, William Harvey described the relationship of the right ventricle (RV) to the pulmonary circulation. For many years after that, this cardiac chamber has been underappreciated. Indeed, in 1943,…
Supraventricular arrhythmias are the most common rhythm disturbance encountered in postsurgical patients. The incidence of postoperative atrial fibrillation may be as high as 50% after cardiac surgery, 40% after pneumonectomy,…
Systemic hypertension remains a global priority because it is common and serious. Hypertension affects approximately 1 billion people worldwide and is responsible for over 9 million deaths each year. It…
The term autonomic dysfunction is frequently associated with the syndrome of critical illness. Numerous studies have reported a striking association among depressed autonomic activity (usually measured as reduced heart rate…
Organ dysfunction is a hallmark of sepsis. Scientific investigation has focused on identifying potential causes and therapeutic targets of this component of the syndrome. Although various pathways and cellular systems…
