Air Embolism

 Venous air embolism is the formation of air bubbles in the veins, causing a blood clot. It is  most common amongst divers or personnels which operate in regions of high pressures. Functionally, it is similar to pulmonary embolism, a venous blood clot, but the clot is an air bubble instead. The severity largely depends on the area clot. For example, the coronary arteries can fall victim to air embolism, which may cause a heart attack or an abnormal heart rhythm. 



Signs and symptoms of an air embolism include: joint or muscle pain, blurred vision, breathlessness or fast breathing and an irregular heartbeat. 


If a patient develops air embolism, the only effective treatment is immediate recompression treatment in a special pressurised room called the hyperbaric chamber. It involves breathing a mixture of gases and oxygen under pressure.After recompression, pressure is gradually reduced to allow the air to leave the body without worsening the situation.


Prevention measures include reducing the depth and duration of your dives, refrain from partaking in dives with a cold, cough or chest infection.

Parkinson's Disease

Parkinson’s disease is a progressive nervous system disorder that affects one’s movements. Parkinson’s disease signs and symptoms are different for every individual and may go unnoticed in the early stage. Symptoms typically start on one side of the body and remain worse on that side even after the symptoms begin appearing in both sides of the body.  Generally, the symptoms of Parkinson’s disease include tremors, slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements such as blinking or swinging of arms when walking, and speech and writing changes.  Parkinson’s disease occurs when neurons in an area of the brain that controls movement becomes impaired or dies. These neurons normally produce dopamine. As more neurons become impaired or die, the amount of dopamine produced in the body is reduced significantly, causing the movement problems associated with Parkinson’s disease.  People with Parkinson’s also lose the nerve endings that produc...

Osteoporosis

Osteoporosis is a bone disease that occurs when there is too little bone or when the body produces too little bone. The word is derived from the terms ‘osteo’ which means ‘bone’ and ‘porosis’ which means porous. Compared to normal bones, the spongy bone has more holes or pores, weakening the structural integrity of the skeleton. Bone cels called Osteoclasts, break down bone tissue and Osteoblasts build bone using minerals such as Calcium and Phosphate. Hormones such as oestrogen and testosterone help to keep the number and activity of Osteoblast high.  There are 2 types of osteoporosis. Primary Osteoporosis is due to old age when Osteoclasts remove more bone than Osteoblast make. This usually happens after the age of 30 when adults reach their ‘peak bone mass’. Secondary Osteoporosis affects both children and adults and mainly stem from cancer, hormonal imbalances or certain use of medications. In severe cases, bones may become too weak to support the rest of the human body and is ...
