Ear Barotrauma

Ear barotrauma During the exams how to become a PADI Dive Instructor there are some questions about barotrauma. What is it and what does it mean? First of a all you can spilt the word in 2 words: baro and trauma. Baro means pressure. Trauma means injury. So the word barotrauma means pressure related injury. During your PADI courses you should know that you have a lot of airspaces during diving: * Sinus * Ears * lungs * Mask A barotrauma can occur in all these air spaces. But today Oceans 5 dive resort is talking about the Ear Barotrauma. How does an ear looks like? ear-anatomy Ear barotrauma is discomfort and possible damage in the ear due to pressure differences between the inside and outside of the eardrum. Causes The air pressure in the middle ear is usually the same as the air pressure outside of the body. The eustachian tube is a connection between the middle ear and the back of the nose and upper throat. Swallowing or yawning opens the eustachian tube and allows air to flow into or out of the middle ear, keeping the air pressure on both sides of the eardrum equal. If the eustachian tube is blocked, the air pressure in the middle ear is different than the pressure on the outside of the eardrum. This can cause barotrauma. Many people experience barotrauma at some time. Barotrauma commonly occurs with altitude changes, such as flying, scuba diving, or driving in the mountains. If you have a congested nose from allergies, colds, or an upper respiratory infection, you are more likely to develop barotrauma. Blockage of the eustachian tube could also be present before birth (congenital), or it may occur because of swelling in the throat. Symptoms • Dizziness • Ear discomfort or pain in one or both ears • Hearing loss (slight) • Sensation of fullness or stuffiness in the ears If the condition is severe or prolonged: • Ear pain • Feeling of pressure in the ears (as if underwater) • Moderate to severe hearing loss • Nosebleed Exams and Tests During an inspection of the ear, the health care provider may see a slight outward bulge or inward pull of the eardrum. If the condition is severe, there may be blood or bruising behind the eardrum. Severe barotrauma may be difficult to tell apart from an ear infection. Treatment To relieve ear pain or discomfort, first try to open the eustachian tube and relieve the pressure. • Chew gum • Inhale, and then gently exhale while holding the nostrils closed and the mouth shut • Suck on candy • Yawn When flying, do not sleep during the descent. Use these measures frequently to open the eustachian tube. Allow infants and children to nurse or sip a drink during descent. Divers should descend and ascend slowly. Diving while you have allergies or a respiratory infection is dangerous, because barotrauma may be severe. If self-care attempts do not relieve your discomfort within a few hours, or if the barotrauma is severe, you may need medical intervention. Medications recommended may include: • Antihistamines • Decongestants taken by mouth or by a nose spray • Steroids These medications may relieve nasal congestion and allow the eustachian tube to open. Antibiotics may prevent ear infection if barotrauma is severe. If the tube will not open with other treatments, surgery may be necessary. A surgical cut is made in the eardrum to allow pressure to become equal and fluid to drain (myringotomy). However, surgery is rarely necessary. If you must make frequent altitude changes or you are susceptible to barotrauma, you may have tubes surgically placed in the eardrum. This is not an option for scuba diving. Outlook (Prognosis) Barotrauma is usually noncancerous (benign) and responds to self-care. Hearing loss is almost always temporary. Possible Complications • Acute ear infection • Hearing loss • Ruptured or perforated eardrum • Vertigo When to Contact a Medical Professional Try home care measures first. If you cannot relieve the discomfort of barotrauma in a few hours, call for an appointment with your health care provider. Call your provider if you have barotrauma and new symptoms develop, especially: • Drainage or bleeding from the ear • Fever • Severe ear pain Prevention You can use nasal decongestants or antihistamines before altitude changes. Try to avoid altitude changes while you have an upper respiratory infection or allergy attack. Talk to your doctor about using decongestants if you plan to scuba dive.

During the IDC the PADI Course Director will test the candidates on their dive knowledge. There are 5 topics in this exam: 1) Physics 2) Physiology 3) Equipment 4) Skills and Environment 5) Decompression Theory and The RDP The Course Directors at Oceans 5 dive resort will have in the IDC preparation days lecture days to brush the candidates knowledge. In one of the topic, Physiology, is a question about Bradycardia. But what is it? [caption id="attachment_2009" align="alignnone" width="300"]IDC Gili Islands with IDC dive resort Oceans 5 Gili Air IDC Gili Islands with IDC dive resort Oceans 5 Gili Air[/caption] strong>Bradycardia (Slow Heart Rate) What is bradycardia? Having bradycardia means that your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy. Or it could be a sign of a problem with the hearts electrical system camera. For some people, a slow heart rate does not cause any problems. It can be a sign of being very fit. Healthy young adults and athletes often have heart rates of less than 60 beats a minute. In other people, bradycardia is a sign of a problem with the heartss electrical system. It means that the heart's natural pacemaker is not working right or that the electrical pathways of the heart are disrupted. In severe forms of bradycardia, the heart beats so slowly that it does not pump enough blood to meet the body's needs. This can cause symptoms and can be life-threatening. Men and women age 65 and older are most likely to develop a slow heart rate that needs treatment. As a person ages, the electrical system of the heart often does not function normally. What causes bradycardia? Bradycardia can be caused by: * Changes in the heart that are the result of aging. * Diseases that damage the heart's electrical system. These include coronary artery disease, heart attack, and infections such as endocarditis and myocarditis. * Conditions that can slow electrical impulses through the heart. Examples include having a low thyroid level (hypothyroidism) or an electrolyte imbalance, such as too much potassium in the blood. * Some medicines for treating heart problems or high blood pressure, such as beta-blockers, antiarrhythmics, and digoxin. What are the symptoms? very slow heart rate may cause you to: * Feel dizzy or lightheaded. * Feel short of breath and find it harder to exercise. * Feel tired. * Have chest pain or a feeling that your heart is pounding or fluttering (palpitations). * Feel confused or have trouble concentrating. * Faint, if a slow heart rate causes a drop in blood pressure. Some people don't have symptoms, or their symptoms are so mild that they think they are just part of getting older.
