Study Notes

Respiratory Distress and Airway Obstruction in Medical Emergencies

General terms related to respiratory distress include anoxia, apnea, dyspnea, hyperpnea, hyperventilation, hypoxia, orthopnea, and tachypnea.
Airway obstruction in medical emergencies can result from a mechanical obstruction, such as the tongue falling into the hypopharynx due to loss of muscle tone, and can lead to unconsciousness.
Hyperventilation, vasodepressor syncope, asthma, heart failure, and hypoglycemia are common causes of respiratory distress.
Clinical manifestations of respiratory distress vary based on the degree of difficulty breathing and can include acute anxiety in patients who are awake.
The pathophysiology of respiratory distress syndromes can involve different parts of the airway, with the level of obstruction determining severity and management.
Management of respiratory distress involves recognizing signs such as wheezing, coughing, abnormal breathing, and providing basic life support while monitoring vitals and managing anxiety.
Foreign body airway obstruction (FBAO) can be critical, particularly in the elderly, children, and sedated patients, and small objects can lead to life-threatening situations.
Prevention of FBAO involves techniques such as using a rubber dam, oral packing, proper patient positioning, and the use of dental instruments and tools.
Management of FBAO includes retrieving visible objects, using radiographs to locate non-visible objects, and addressing aspirated foreign bodies through procedures like fiberoptic bronchoscopy or thoracotomy.
Recognition of acute airway obstruction, whether complete or partial, is crucial, with different phases and signs indicating the urgency of intervention.
Basic airway maneuvers like head tilt-chin lift and jaw thrust are essential for establishing an emergency airway in patients with airway obstruction.
Hyperventilation is characterized by excessive ventilation, leading to symptoms such as faintness, lightheadedness, and increased blood pressure and respiratory rate, with management aimed at correcting the respiratory problem and reducing anxiety levels.
