the rapid cycling specifier refers to an individual with bipolar disorder who experiences at least
Bipolar disorder Most people who meet criteria for bipolar disorder experience a number of episodes, on average 0.4 to 0.7 per year, lasting three to six months.[89] Rapid cycling, however, is a course specifier that may be applied to any of the above subtypes. It is defined as having four or more mood disturbance episodes within a one-year span and is found in a significant proportion of individuals with bipolar disorder.[24] These episodes are separated from each other by a remission (partial or full) for at least two months or a switch in mood polarity (i.e., from a depressive episode to a manic episode or vice versa).[11] The definition of rapid cycling most frequently cited in the literature (including the DSM) is that of Dunner and Fieve: at least four major depressive, manic, hypomanic or mixed episodes are required to have occurred during a 12-month period.[90] Ultra-rapid (days) and ultra-ultra rapid or ultradian (within a day) cycling have also been described.[91] The literature examining the pharmacological treatment of rapid cycling is sparse and there is no clear consensus with respect to its optimal pharmacological management.[92]
Rapid response team (medicine) A rapid response team (RRT), also known as a medical emergency team (MET) and high acuity response team (HART), is a team of health care providers that responds to hospitalized patients with early signs of deterioration on non-intensive care units to prevent respiratory or cardiac arrest. The health care providers are trained in early resuscitation interventions and advanced life support and may include a physician, nurse, or respiratory therapist. The RRT, medical emergency team (MET), critical care outreach team (CCOT), and rover team are all different forms of the outgoing component of the rapid response system. The team responds to calls placed by clinicians or families at the bedside who have detected deterioration.[1][2][3] Some teams may also provide care during transport between hospitals, acting as a critical care transport team.[4]
