If a driver pinned in an MVC has tension pneumothorax diagnosed, what should be the next step after improving SpO₂ with a needle decompression?

After performing a needle decompression to relieve tension pneumothorax and subsequently improving the patient's SpO₂ levels, the next essential step is to monitor the patient and prepare for transport to a trauma center. This is crucial because while needle decompression is an immediate intervention that alleviates the life-threatening situation of tension pneumothorax, the patient still requires further evaluation and management by a higher level of care.

Post-decompression, monitoring the patient's vital signs and response is vital to ensure that the intervention has effectively resolved the critical condition. Transporting the patient to a trauma center facilitates access to advanced imaging and surgical interventions if necessary. It also ensures that the patient is managed by a team experienced in trauma care, enhancing their chances of recovery.

While applying a chest seal can be a part of managing an open pneumothorax, it follows the immediate needle decompression, which has already been addressed. Placing a second needle could be considered in cases where the first decompression did not succeed, but in this scenario, it's more focused on transporting the patient for comprehensive care. Rapid Sequence Intubation (RSI) is typically not indicated unless the patient's airway is compromised beyond the immediate impacts of the tension pneumothorax, thus monitoring and
