Supraglottic Airway Devices

What is the King LT airway primarily used for?

• To provide positive pressure ventilation to apneic patients.

• To administer medications.

• To measure oxygen saturation.

• To monitor heart rate.

What is the difference in oxygen and carbon dioxide movement across the alveolar membrane due to?

• The difference in gas solubility in the blood.

• The size of the alveoli.

• The patient's age.

• The type of ventilator used.

What is the function of the distal cuff when the King LT airway is properly placed?

• Seals the trachea

• Seals the esophagus

• Seals the oropharynx

• Seals the nasal cavity

Which of the following is an indication for using the King LT airway?

• Patients with known esophageal disease

• Patients with a caustic substance ingestion

• Failed intubation attempt

• Patients with an intact gag reflex

What is a potential complication of the King LT airway?

• Increased airway pressure

• Laryngospasm

• Enhanced ventilation

• Reduced risk of aspiration

What is the primary purpose of the laryngeal mask airway (LMA)?

• To provide a conduit from the glottic opening to the ventilation device

• To replace the need for bag-mask ventilation

• To serve as a permanent airway solution

• To be used exclusively in emergency situations

What should be done first when inserting a King LT airway?

• Preoxygenate the patient with a bag-mask device and 100% oxygen

• Take standard precautions

• Gather your equipment

• Place the patient's head in a neutral position

What should you do if you meet resistance while advancing the tip of the King LT Airway beyond the base of the tongue?

• Use excessive force to push the device further.

• Change your angle and advance it again.

• Inflate the cuffs with the maximum amount of air.

• Stop the procedure immediately.

In which patients should we avoid use of the LMA?

• Patients in cardiac arrest

• Patients with morbid obesity.

• Patients with COPD.

• Patients with heart failure.

What is one advantage of the LMA compared to ET intubation?

• It requires laryngoscopy.

• It provides better ventilation than a bag-mask device.

• It is more effective for patients with high pulmonary pressures.

• It is easier because it does not require laryngoscopy.
