Final answer:
Intubation is indicated for asthma patients experiencing severe respiratory distress, signs of impending respiratory failure, and a poor response to bronchodilator therapy during an acute exacerbation.
Step-by-step explanation:
Indications for Intubating Asthma Patients with Acute Exacerbations
Indications for intubating patients with acute asthma exacerbations are severe in nature and may include life-threatening respiratory distress such as rapid worsening of shortness of breath, inability to speak due to dyspnea, cyanosis of lips or face, altered mental status including confusion and drowsiness, a rapid pulse, sweating, and severe anxiety. Additionally, signs of impending respiratory failure, such as silent chest (absence of wheezing on auscultation due to very limited airflow), paradoxical chest or abdominal movement (indicates respiratory muscle fatigue), and a poor response to initial bronchodilator therapy, are clear indications. Intubation in asthma patients allows for mechanical ventilation to support breathing and protect the airway, especially when there is an impending risk of respiratory arrest.
