Final answer:
The question concerns emergency medical techniques, specifically using an airway adjunct and BVM to assist ventilation in individuals incapable of breathing adequately on their own. Medical advancements have improved the survival rates for conditions like RDS, and interventions include resuscitation, intubation, CPAP, and mechanical ventilation.
Step-by-step explanation:
The question relates to emergency medical procedures to assist breathing, which include the use of an airway adjunct and a bag-valve-mask (BVM). Medical knowledge and advances, such as the introduction of pulmonary surfactant therapy, have significantly reduced mortality associated with respiratory distress syndrome (RDS) in infants. Treatments may involve measures like resuscitation, intubation, CPAP (continuous positive airway pressure), and mechanical ventilation to support patients until they can breathe adequately on their own.
In the adult scenario presented by the question, inserting an airway adjunct is done to keep the airway open, and using a BVM assists in ventilating a person who is not breathing or is breathing inadequately. When an object obstructs the airway, procedures like the Heimlich maneuver or intubation are critical to restore air flow to the lungs. In a setting outside immediate clinical care, such as ambulance crews, these measures are crucial for patient survival.
