you want the tip of ET tube where in body

A

3-4 cm above carina

35
Q

Where is the tip for a straight blade laryngoscope

just below epilottis

36
Q

What do you do tog verifty ET tube placement

A

look for symmetrical rise and equal breath sounds b/l over epigastrum
secure tube to skin
do CXR to confirm correct placement
monitor rep valuse and confirm proper function
