A case of a 55-year-old woman with iatrogenic vocal cord trauma and sleep-related symptoms is reported. In particular, this case highlights sleep-disordered breathing as a delayed complication after iatrogenic vocal cord trauma. The patient developed acute stridor from a contralateral vocal cord hematoma following vocal fold injection for right vocal cord paralysis. Acute respiratory symptoms resolved with oxygen, steroids, and nebulized therapy, but nocturnal symptoms persisted and polysomnography revealed sleep-related hypoventilation and mild obstructive sleep apnea. Positive pressure therapy was successfully used to ameliorate her symptoms and treat sleep-disordered breathing until her hematoma resolved. In addition to the typically acute respiratory symptoms that may result from vocal cord dysfunction, sleep-disordered breathing may also present as a significant subacute or chronic problem. Management of the acute respiratory symptoms is relatively well established, but clinicians should be alert for more subtle nocturnal symptoms that may require further study with polysomnography.

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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...

Alterations in Respiration II01:30

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Endotracheal Tube Extubation01:24

Endotracheal Tube Extubation

Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
