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.
After determining the scene is safe, approach the patient and attempt to converse with him or her. If the patient responds verbally, you have established that there is at least a partially patent airway and that the patient is breathing (therefore not currently in respiratory arrest).
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 .
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 .
Close monitoring by the anesthesia provider will sometimes be provided, to help keep the patient comfortable during a medical procedure, along with other drugs to help relax the body. It can also help control breathing, blood pressure, blood flow, and heart rate and rhythm, when needed. [1] There are four levels of sedation by anesthesia.
Intubation with a cuffed tube is thought to provide the best protection against aspiration. Downside of tracheal tubes is the pain and coughing that follows. Therefore, unless a patient is unconscious or anesthetized, sedative drugs are usually given to provide tolerance of the tube.
Normal breathing rates are between 12 and 20 breaths per minute, [14] and if a patient is breathing below the minimum rate, then in current ILCOR basic life support protocols, CPR should be considered, although professional rescuers may have their own protocols to follow, such as artificial respiration.
Signs and symptoms vary based on the location and severity of the injury; they commonly include dyspnea (difficulty breathing), dysphonia (a condition where the voice can be hoarse, weak, or excessively breathy), coughing, and abnormal breath sounds. In the emergency setting, tracheal intubation can be used to ensure that the airway remains ...
