Summary
Paradoxical vocal fold motion disorder (PVFMD) causes sudden upper airway obstruction. This review clarifies emergency department evaluation and management for this rare condition.
Area of Science:
- Emergency Medicine
- Otolaryngology
- Pulmonology
Background:
- Paradoxical vocal fold motion disorder (PVFMD), or vocal cord dysfunction, is a poorly understood cause of acute upper airway obstruction.
- Patients often present to the emergency department (ED) with respiratory distress and stridor, mimicking other acute conditions.
- Misdiagnosis or delayed diagnosis of PVFMD can lead to unnecessary interventions like intubation or surgical airways.
Purpose of the Study:
- To summarize the emergency department presentation of PVFMD.
- To outline the acute evaluation and management strategies for PVFMD.
Main Methods:
- Literature review focusing on ED presentation and acute management of PVFMD.
- Synthesis of current understanding regarding diagnostic challenges and therapeutic approaches.
Main Results:
- PVFMD is an underrecognized cause of acute respiratory distress in the ED.
- Familiarity with PVFMD presentation is crucial to avoid misdiagnosis and inappropriate procedures.
- Specific diagnostic clues and initial management steps are essential for timely care.
Conclusions:
- PVFMD requires prompt recognition and appropriate management in the emergency setting.
- Further research into acute PVFMD is needed to improve patient outcomes.
- Education for emergency physicians on PVFMD is critical for reducing diagnostic errors.

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
