Decompression Sickness

Decompression sickness, also known as the bends, is a condition that can occur when scuba divers ascend too quickly from a dive, causing gas bubbles to form in the bloodstream and tissues. These bubbles can cause a range of symptoms, including joint pain, muscle weakness, and skin rashes. In severe cases, decompression sickness can lead to neurological symptoms such as numbness, tingling, and even paralysis.

While decompression sickness is not a lung problem per se, it can affect the lungs by causing difficulty breathing and shortness of breath. This is because the gas bubbles that form in the bloodstream can block small blood vessels in the lungs, making it difficult for oxygen to reach the body’s tissues.

The risk of decompression sickness is highest in divers who make rapid ascents, such as those who do not follow proper decompression procedures or ascend too quickly after a dive. Divers who have a history of lung problems, such as asthma or chronic obstructive pulmonary disease (COPD), may also be at increased risk for decompression sickness.

It is important for scuba divers to be aware of the risks of decompression sickness and to take steps to prevent it. This includes following proper decompression procedures, avoiding rapid ascents, and avoiding diving if you have a history of lung problems. If you experience symptoms of decompression sickness, such as joint pain or difficulty breathing, it is important to seek medical attention immediately.

Pulmonary Barotrauma

Pulmonary barotrauma is a serious and potentially life-threatening condition that can occur during scuba diving. It is caused by a rapid change in pressure that results in damage to the lungs. There are two main types of pulmonary barotrauma:

  1. Barotraumas:
    • Sinus barotrauma: This type of barotrauma occurs when the pressure in the sinuses is greater than the pressure in the surrounding tissue, causing the sinuses to rupture and blood to fill the surrounding tissue.
    • Pneumothorax: This type of barotrauma occurs when the pressure in the lungs is greater than the pressure in the surrounding tissue, causing the lungs to collapse and air to fill the space between the lungs and the chest wall.
  2. Mesothorax: This type of barotrauma occurs when the pressure in the chest is greater than the pressure in the surrounding tissue, causing the mediastinal tissue to shift and compress the lungs.

Both types of pulmonary barotrauma can occur during ascent from a dive, when the pressure outside the body is less than the pressure inside the body. The severity of the condition depends on the depth and duration of the dive, as well as the rate at which the diver ascends. Symptoms of pulmonary barotrauma can include chest pain, difficulty breathing, coughing, and blood in the mucus.
