Endotracheal intubation

(ETI) to maintain an open airway and channel to administer medications if necessary. The ETA is passed through the mouth and vocal cords and into the trachea. Clinical signs -- such as mist in the ETA, chest rise with each breath, and breath sounds from air movement in both lungs -- indicate successful intubation. In emergency or critical situations, such as during cardiac arrest, rapid sequence induction (RSI) of anesthesia and intubation may be employed. RSI is performed by inducing unconsciousness and muscle relaxation with various medications.
Iff other methods of management have been unsuccessful or are not recommended in a particular situation, surgical intervention for airway management may be required.
Cricothyrotomy is a surgical method in which an incision is made in the cricothyroid membrane, which connects the thyroid and cricoid cartilages of the larynx in critical situations. A tracheostomy tube is then inserted into the incision to achieve a functioning airway. This can be confirmed through breath sounds in the lungs as well as through observation of rise and fall of the chest.
Tracheotomy is another surgical procedure in which an incision in the neck is made to insert a breathing tube into the trachea, used in situations where mechanical ventilation may be required for extended periods of time.
