However, it is important how significant the increased blood pressure is and whether there are already collateral effects caused by hypertension (a condition known as ‘hypertensive heart disease’). Another important aspect is anti-hypertensive drug therapy. Since in most cases an increased blood pressure requires treatment with medication with possible significant side effects, it’s necessary to evaluate whether these medications are compatible with recreational diving (with a focus on the beta-blocker class).[/vc_column_text][/vc_column][/vc_row]

Respuesta de los expertos de DAN:

De acuerdo con las directrices de la Sociedad Suiza de Medicina Subacuática e Hiperbárica (SUHMS), un buceador con FOP de grado 2 y 3 puede bucear siguiendo las «recomendaciones para el buceo con pocas burbujas»:

• • Realiza primero la fase profunda de la inmersión y evita las inmersiones en yo-yo (evita entrar repetidamente en la zona de 0-10 metros).
  • Reduzca la velocidad de superficie a 5 metros por minuto en los 10 metros superiores.
  • Realice una parada de seguridad a una profundidad de entre 3 y 5 metros durante al menos 5-10 minutos.
  • No llegue al límite de una inmersión sin descompresión. No realice inmersiones con obligación de parada de descompresión.
  • Intervalo en superficie de al menos 4 horas antes de la siguiente inmersión.
  • Máximo dos inmersiones al día.
  • Evite el calentamiento intenso de la piel después de la inmersión (por ejemplo: tomar el sol, duchas calientes, sauna).
  • Prefiero el buceo con Nitrox, utilizando tablas de descompresión con aire o ajustes en el ordenador, prestando atención a la toxicidad del oxígeno.
  • Los ordenadores de buceo especiales o el software pueden reducir el riesgo.

No obstante, la cirugía será eficaz y, tras una recuperación completa, podrá volver a bucear.

I know I can undergo surgery and have it closed with an umbrella device. Would the surgery be a resolution? Can I dive regularly after it?

Answer from DAN experts:

In accordance with the Swiss Underwater and Hyperbaric Medical Society (SUHMS) guidelines, a diver with 2nd and 3rd Grade PFO can dive according to “low bubble diving recommendations”:

• Perform the deep phase of the dive first and avoid yo-yo dives (avoid repetitive entry into the 0-10 meter zone)
• Reduce surfacing speed to 5 meters per minute in the upper 10 meters
• Perform a safety stop at 3-5 meters depth for at least 5-10 minutes
• Don’t go to the limit of a no-decompression dive – Don’t perform dives with a decompression stop obligation
• Surface interval of at least 4 hours before the next dive
• Maximum of two dives a day
• Avoid intense skin warming after the dive (e.g.: sunbathing, hot shower, sauna)
• Prefer Nitrox Diving, using air decompression tables or computer setting, paying attention to oxygen toxicity
• Special dive computers or software may reduce the risk
• Moreover, to decrease the risk of bubbles transfer into the arterial blood stream:a) avoid strenuous physical efforts during the last 10 metres of ascent, such as swimming against current at the end of the dive.

  b) avoid exhausting physical activity during two hours following the dive

  c) It is absolutely contraindicated to dive when having a cold. Coughing and forced Valsalva maneuver facilitate bubble transfer into the arterial blood stream.

  Nonetheless, the surgery will be effective and after a complete healing you can go back to diving again.
