Which of the following might help break a laryngospasm?

A soothing voice and airway maintenance are effective methods for breaking a laryngospasm because these strategies help to reduce patient anxiety and stimulate relaxation, which can alleviate the muscle spasm of the vocal cords. During a laryngospasm, the airway is constricted, making it difficult for air to pass and possibly leading to distress for the patient. By utilizing a calming approach, healthcare providers can create a more comfortable environment that facilitates the natural relaxation of the airway structures. Additionally, maintaining the airway through careful positioning or gentle maneuvering can assist in reopening the airway and relieving the spasm.

Other approaches, while they may be helpful in emergency situations, do not directly address the underlying issue of laryngospasm in the same manner. For example, bilateral lung auscultation, while essential in assessing respiratory function, does not provide immediate relief from the spasm. Increased oxygen delivered through nasal cannula may help support oxygenation but would not resolve the spasm itself. Rapid intubation, though a potential solution for severe airway compromise, is an invasive procedure that may not be necessary if less aggressive measures, such as soothing communication, are effective in addressing laryngospasm.
