What issue occurs with breath stacking during ventilation?

• A. Patient receives fewer breaths
• B. Increased pressures in the chest
• C. Improved synchronization of breaths
• D. Lower risk of respiratory muscle atrophy

Answer: (B)

Breath stacking during ventilation refers to a situation where more than one breath is delivered before the previous breath is exhaled. This can happen in patients who are on mechanical ventilation, especially if the ventilator settings allow for rapid successive breaths or if the patient is attempting to initiate their own breaths while still connected to the ventilator. When breath stacking occurs, it results in increased pressures in the chest. This is due to the accumulation of air within the lungs without sufficient time for full exhalation. As more breaths are delivered, the intrathoracic pressure rises, which can lead to complications such as barotrauma, overdistension of the lungs, and impaired hemodynamics. Understanding this phenomenon is critical for those involved in ventilation management, as it underscores the importance of monitoring patient-ventilator synchronization and the adequate timing of breath delivery to prevent increased intrathoracic pressures and their associated risks.
