Final answer:
Secondary methods to confirm SGA placement include auscultation, capnography, and chest rise.
Step-by-step explanation:
Secondary methods to confirm SGA (Supraglottic Airway) placement include Auscultation, which involves listening for breath sounds over the chest and abdomen using a stethoscope. Correct placement of SGA can be confirmed by the presence of bilateral breath sounds.
Another method is Capnography, which measures the amount of carbon dioxide (CO2) in exhaled breath. Proper SGA placement should result in a normal capnography waveform.
Chest rise is another method to confirm SGA placement. When the SGA is correctly placed, the chest should rise and fall with each breath.
