The type of decompression sickness associated with pulmonary issues is referred to as Type 2 decompression sickness. This form occurs when nitrogen bubbles form in the body's tissues and potentially affect the lungs, leading to significant respiratory complications.

In Type 2 decompression sickness, the nitrogen bubbles can obstruct blood vessels and lead to symptoms such as chest pain, difficulty breathing, and other pulmonary symptoms due to the impact on lung function. This condition can be life-threatening and requires immediate medical intervention, often through hyperbaric oxygen therapy.

Understanding the different types of decompression sickness is crucial for aviation and diving professionals, as Type 1 typically affects only the skin and joints, while Type 3 and Type 4 classifications do not relate to pulmonary involvement. This distinction helps prioritize treatments and responses that address the specific symptoms and risks associated with each type.
