Difficult Direct Laryngoscopy Quiz

Asthma, COPD, and adult respiratory distress syndrome (ARDS) are strong predictors.

Obesity leads to redundant upper airway tissues and increases chest wall weight, which can obstruct the airway.

A high Mallampati classification indicates a greater risk for difficult bag-mask ventilation.

The ability to visualize the vocal cords using a direct laryngoscope, essential for successful intubation.

A grading system used to assess the view of the vocal cords during direct laryngoscopy (DL). Grades I and II indicate good visualization, while III and IV indicate poor visualization.

Factors that may predict difficult direct laryngoscopy (DL), making intubation more challenging.

A technique that uses a camera-equipped laryngoscope to visualize the airway, offering a more comprehensive view.

A mnemonic used to screen for potential difficult intubation, helping to predict airway challenges.

The first step in the LEMON assessment, evaluating external factors that might indicate difficult intubation, like facial injuries or a stiff neck.

The second step in the LEMON assessment, evaluating the patient's airway geometry using a simple measurement system to predict suitability for direct laryngoscopy (DL).

A measurement of the distance between the thyroid notch (Adam's apple) and the tip of the chin, used to assess the adequacy of the airway.

Resistance to ventilation caused by lung conditions like asthma, COPD, or ARDS, prior radiation to the head and neck, or a history of difficult intubation.

Conditions like airway obstruction, obesity, or obstructive sleep apnea can make mask ventilation hard due to anatomical challenges.

A higher Mallampati score, poor mask fit, and male gender increase the likelihood of challenges with mask ventilation.

Patients older than 55 years are more likely to experience difficult BMV.

The absence of teeth makes mask ventilation challenging due to poor mask seal.

A method to assess difficult intubation based on finger measurements. It involves placing fingers between the incisors, along the mandible, and from the laryngeal prominence to the chin.

A scale to assess oral access and predict difficulty with intubation. It categorizes the visibility of the soft palate, tonsils, and uvula.

The presence of any obstruction or blockage in the upper airway. It can interfere with visualization of the glottis and intubation.

The range of motion of the patient's neck, specifically the ability to flex and extend the head. It's crucial for positioning during intubation.

The ability of the provider to ventilate the patient with a bag-valve mask without resistance. Factors like obesity, facial anatomy, and airway obstruction can make it difficult.

A mnemonic used to recognize factors that might make intubation challenging. It stands for: L - Look externally (thyromental distance), E - Evaluate (Mallampati score), M - Mallampati score, O - Obstruction, N - Neck mobility.

A mnemonic used to evaluate difficult bag-valve mask ventilation. It stands for: R - Radiation or resistance to ventilation, O - Obstruction, obesity, and obstructive sleep apnea, M - Mallampati, male, mask seal, A - Age, N - No teeth.

The use of external visual aids like a laryngoscope to visualize the larynx during intubation. It's a common technique for securing an airway.

A method of inserting a tube into the trachea for airway management. This procedure requires a clear view of the larynx to successfully place the tube.

A breathing technique where a tube is inserted into the trachea to provide an airway. It's often used when the patient cannot breathe on their own.

A device used for ventilation that provides an artificial airway for breathing. It's especially useful when the patient cannot breathe independently.

The procedure of providing artificial respiration using a bag-valve mask device. It's used to provide positive pressure ventilation and oxygen to the patient.

A quick medical procedure involving the administration of medications followed by intubation to ensure control of the airway.

A type of airway device placed above the vocal cords. It provides an alternative airway when conventional intubation is difficult or impossible.

A mnemonic used to evaluate difficult extraglottic device placement. It stands for: R - Restricted mouth opening or resistance to ventilation, O - Obstruction, obesity, or obstructive sleep apnea, D - Distorted anatomy, S - Short thyromental distance.
