One important difference between RSI and routine tracheal intubation is that the practitioner does not manually assist the ventilation of the lungs after the onset of general anesthesia and cessation of breathing, until the trachea has been intubated and the cuff has been inflated.
Treatment varies depending on the cause of respiratory arrest. In many cases, it is necessary to establish an alternate airway and providing artificial ventilation that can include modes of mechanical ventilation. There are many ways to provide an airway and to deliver breathing support. The list below includes several options.
The patient's natural breathing may be inadequate during the procedure and intervention is often necessary to protect the airway. [ 5 ] Various drugs are used to achieve unconsciousness , amnesia , analgesia , loss of reflexes of the autonomic nervous system , and in some cases paralysis of skeletal muscles .
Tracheal intubation, often simply referred to as intubation, is the placement of a flexible plastic or rubber endotracheal tube (ETT) into the trachea to maintain an open airway, allow for effective ventilation, protect the airway from aspiration (when a cuffed ETT is used), and to serve as a conduit through which to administer inhaled anesthetics.
In anaesthesia and advanced airway management, rapid sequence induction (RSI) – also referred to as rapid sequence intubation or as rapid sequence induction and intubation (RSII) or as crash induction [1] – is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration.
A RSBI score of less than 65 [3] indicating a relatively low respiratory rate compared to tidal volume is generally considered as an indication of weaning readiness. A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure. [4]
In addition, it plays an important role in facilitating mechanical ventilation in patients with poor lung function. Patients are still aware of pain even after full conduction block has occurred; hence, general anesthetics and/or analgesics must also be given to prevent anesthesia awareness .
Return of spontaneous circulation (ROSC) is the resumption of a sustained heart rhythm that perfuses the body after cardiac arrest. It is commonly associated with significant respiratory effort. Signs of return of spontaneous circulation include breathing, coughing, or movement and a palpable pulse or a measurable blood pressure.
