Immersion Pulmonary Oedema (IPO), also known as Immersion Pulmonary Edema (IPE) or Swimming-Induced Pulmonary Edema (SIPE), is a condition where fluid accumulates in the lungs during immersion in water, making breathing difficult and potentially leading to drowning. It can affect divers and swimmers, even those who are fit and experienced. IPO is triggered by factors such as cold water, exertion, high blood pressure, and increased breathing resistance. Symptoms include shortness of breath, coughing (sometimes with frothy or blood-tinged sputum), and chest discomfort. Prompt recognition, ending the dive safely, and seeking medical help are crucial for managing IPO and preventing serious complications.

Diving after IPO?

In short, no.

Due to the risks related to a previous IPO, compressed gas diving is not advisable.  More details are available in the 2024 Joint Position Statement on IPO and Diving.

If you have had IPO while diving, seek the advice of a diving medical specialist.
