What happens to peak inspiratory pressure during acute bronchospasm?

• A. It remains constant
• B. It decreases significantly
• C. It rises due to increased airway resistance
• D. It can lead to hypoventilation if unmanaged

Answer: (C)

During acute bronchospasm, peak inspiratory pressure rises due to increased airway resistance. This condition occurs when the airways constrict and become narrowed, making it more difficult for air to flow in and out of the lungs. As a result, the ventilator must exert more pressure to deliver the same volume of air, leading to an increase in peak inspiratory pressure. This is a critical consideration in managing patients with bronchospasm, as elevated pressures can indicate worsening airway obstruction and may require interventions such as bronchodilator administration to alleviate the spasm and reduce airway resistance.

Understanding this relationship is essential for healthcare providers, as it highlights the importance of monitoring ventilatory parameters in patients experiencing bronchospasm, ensuring appropriate treatment is applied to prevent complications such as hypoventilation or respiratory failure.
