An attempt at intubating should not exceed:

Mrs. Miller is orotracheally intubated with a size 7.5 mm ETT. It has been determined that Mrs. Miller’s ETT needs to be replaced. The physician has instructed you to change the tube with a tube exchanger. According to the CXR, Mrs. Miller’s ETT is 3 cm above the carina. Refer to the image below to answer the following question. Using the ETT placement at the corner of the mouth as your landmark, the safest minimal to maximal depths to insert and maintain the tube exchanger during the exchange is: ET tube position.png 

While monitoring capnography during mechanical ventilation, you note the PetCO2 has increased from 20 mmHg to 40 mmHg. All the following are potential causes except:

This equipment is used when performing NT intubation via direct visualization:

A patient in the ICU is on mechanical ventilation, has continuous capnography monitoring and a pulmonary artery catheter in place. The patient’s PaCO2 is 41 mmHg and the PetCO2 has been averaging 34 mmHg. You respond to the ventilator alarming “Low EtCO2” and find the PetCO2 has suddenly decreased from 34 mmHg to 18 mmHg. The most likely cause of this is:
