Transcatheter closure of patent foramen ovale using the Amplatzer septal occluder to prevent recurrence of neurological decompression illness in divers. (1/538)
OBJECTIVE: Large flap valve patent foramens may cause paradoxical thromboembolism and neurological decompression illness in divers. The ability of a self expanding Nitinol wire mesh device (Amplatzer septal occluder) to produce complete closure of the patent foramen ovale was assessed. PATIENTS: Seven adults, aged 18-60 years, who had experienced neurological decompression illness related to diving. Six appeared to have a normal atrial septum on transthoracic echocardiography, while one was found to have an aneurysm of the interatrial septum. METHODS: Right atrial angiography was performed to delineate the morphology of the right to left shunt. The defects were sized bidirectionally with a precalibrated balloon filled with dilute contrast. The largest balloon diameter that could be repeatedly passed across the septum was used to select the occlusion device diameter. Devices were introduced through 7 F long sheaths. All patients underwent transthoracic contrast echocardiography one month after the implant. RESULTS: Device placement was successful in all patients. Device sizes ranged from 9-14 mm. The patient with an aneurysm of the interatrial septum had three defects, which were closed with two devices. Right atrial angiography showed complete immediate closure in all patients. Median (range) fluoroscopy time was 13.7 (6-35) minutes. Follow up contrast echocardiography showed no right to left shunting in six of seven patients and the passage of a few bubbles in one patient. All patients have been allowed to return to diving. CONCLUSION: The Amplatzer septal occluder can close the large flap valve patent foramen ovale in divers who have experienced neurological decompression illness. Interatrial septal aneurysms with multiple defects may require more than one device. (+info)Experiment of nitrox saturation diving with trimix excursion. (2/538)
Depth limitations to diving operation with air as the breathing gas are well known: air density, oxygen toxicity, nitrogen narcosis and requirement for decompression. The main objectives of our experiment were to assess the decompression, counterdiffusion and performance aspect of helium-nitrogen-oxygen excursions from nitrox saturation. The experiment was carried out in a wet diving stimulator with "igloo" attached to a 2-lock living chamber. Four subjects of two teams of 2 divers were saturated at 25 msw simulated depth in a nitrogen oxygen chamber environment for 8 days, during which period they performed 32 divers-excursions to 60 or 80 msw pressure. Excursion gas mix was trimix of 14.6% oxygen, 50% helium and 35.4% nitrogen, which gave a bottom oxygen partial pressure of 1.0 bars at 60 msw and 1.3 at 80 msw. Excursions were for 70 min at 60 msw with three 10-min work periods and 40 min at 80 msw with two 10-min work periods. Work was on a bicycle ergometer at a moderate level. We calculated the excursion decompression with M-Values based on methods of Hamilton (Hamilton et al., 1990). Staged decompression took 70 min for the 60 msw excursion and 98 min for 80 msw, with stops beginning at 34 or 43 msw respectively. After the second dive day bubbles were heard mainly in one diver but in three divers overall, to Spencer Grade III some times. No symptoms were reported. Saturation decompression using the Repex procedures began at 40 msw and was uneventful: Grade II and sometimes III bubbles persisted in 2 of the four divers until 24 hr after surfacing. We conclude that excursions with mixture rich in helium can be performed effectively to as deep as 80 msw using these procedures. (+info)Development of diving capacity in emperor penguins. (3/538)
To compare the diving capacities of juvenile and adult emperor penguins Aptenodytes forsteri, and to determine the physiological variables underlying the diving ability of juveniles, we monitored diving activity in juvenile penguins fitted with satellite-linked time/depth recorders and examined developmental changes in body mass (Mb), hemoglobin concentration, myoglobin (Mb) content and muscle citrate synthase and lactate dehydrogenase activities. Diving depth, diving duration and time-at-depth histograms were obtained from two fledged juveniles during the first 2.5 months after their depature from the Cape Washingon colony in the Ross Sea, Antarctica. During this period, values of all three diving variables increased progressively. After 8-10 weeks at sea, 24-41 % of transmitted maximum diving depths were between 80 and 200 m. Although most dives lasted less than 2 min during the 2 month period, 8-25 % of transmitted dives in the last 2 weeks lasted 2-4 min. These values are lower than those previously recorded in adults during foraging trips. Of the physiological variables examined during chick and juvenile development, only Mb and Mb content did not approach adult values. In both near-fledge chicks and juveniles, Mb was 50-60 % of adult values and Mb content was 24-31 % of adult values. This suggests that the increase in diving capacity of juveniles at sea will be most dependent on changes in these factors. (+info)Heart rate and behavior of fur seals: implications for measurement of field energetics. (4/538)
Archival data loggers were used to collect information about depth, swimming speed, and heart rate in 23 free-ranging antarctic fur seals. Deployments averaged 9.6 +/- 5.6 days (SD) and totaled 191 days of recording. Heart rate averaged 108.7 +/- 17.7 beats/min (SD) but varied from 83 to 145 beats/min among animals. Morphometrics explained most variations in heart rate among animals. These interacted with diving activity and swimming speed to produce a complex relationship between heart rate and activity patterns. Heart rate was also correlated with behavior over time lags of several hours. There was significant (P < 0.05) variation among animals in the degree of diving bradycardia. On average, heart rate declined from 100-130 beats/min before the dive to 70-100 beats/min during submersion. On the basis of the relationship between heart rate and rate of oxygen consumption, the overall metabolic rate was 5.46 +/- 1.61 W/kg (SD). Energy expenditure appears to be allocated to different activities within the metabolic scope of individual animals. This highlights the possibility that some activities can be mutually exclusive of one another. (+info)Convective oxygen transport and tissue oxygen consumption in Weddell seals during aerobic dives. (5/538)
Unlike their terrestrial counterparts, marine mammals stop breathing and reduce their convective oxygen transport while performing activities (e.g. foraging, courtship, aggressive interactions, predator avoidance and migration) that require sustained power output during submergence. Since most voluntary dives are believed to remain aerobic, the goal of this study was to examine the potential importance of the dive response in optimizing the use of blood and muscle oxygen stores during dives involving different levels of muscular exertion. To accomplish this, we designed a numerical model based on Fick's principle that integrated cardiac output (Vb), regional blood flow, convective oxygen transport (Q(O2)), muscle oxymyoglobin desaturation and regional rates of oxygen consumption (VO2). The model quantified how the optimal matching or mismatching of QO2 to VO2 affected the aerobic dive limit (ADL). We chose an adult Weddell seal Leptonycotes weddellii on which to base our model because of available data on the diving physiology and metabolism of this species. The results show that the use of blood and muscle oxygen stores must be completed at the same time to maximize the ADL for each level of VO2. This is achieved by adjusting Vb (range 19-94 % of resting levels) and muscle QO2 according to the rate of muscle oxygen consumption (VMO2). At higher values of VMO2, Vb and muscle perfusion must increase to maintain an appropriate QO2/VO2 ratio so that available blood and muscle oxygen stores are depleted at the same time. Although the dive response does not sequester blood oxygen exclusively for brain and heart metabolism during aerobic dives, as it does during forced submersion, a reduction in Vb and muscle perfusion below resting levels is necessary to maximize the ADL over the range of diving VO2 (approximately 2-9 ml O2 min-1 kg-1). Despite the reduction in Vb, convective oxygen transport is adequate to maintain aerobic metabolism and normal function in the splanchnic organs, kidneys and other peripheral tissues. As a result, physiological homeostasis is maintained throughout the dive. The model shows that the cardiovascular adjustments known as the dive response enable the diving seal to balance the conflicting metabolic demands of (1) optimizing the distribution and use of blood and muscle oxygen stores to maximize the ADL over the normal range of diving VO2 and (2) ensuring that active muscle receives adequate oxygen as VMO2 increases. (+info)Diving and the risk of barotrauma. (6/538)
STUDY OBJECTIVES: Pulmonary barotrauma (PBT) of ascent is a feared complication in compressed air diving. Although certain respiratory conditions are thought to increase the risk of suffering PBT and thus should preclude diving, in most cases of PBT, risk factors are described as not being present. The purpose of our study was to evaluate factors that possibly cause PBT. DESIGN: We analyzed 15 consecutive cases of PBT with respect to dive factors, clinical and radiologic features, and lung function. They were compared with 15 cases of decompression sickness without PBT, which appeared in the same period. RESULTS: Clinical features of PBT were arterial gas embolism (n = 13), mediastinal emphysema (n = 1), and pneumothorax (n = 1). CT of the chest (performed in 12 cases) revealed subpleural emphysematous blebs in 5 cases that were not detected in preinjury and postinjury chest radiographs. A comparison of predive lung function between groups showed significantly lower midexpiratory flow rates at 50% and 25% of vital capacity in PBT patients (p < 0.05 and p < 0.02, respectively). CONCLUSIONS: These results indicate that divers with preexisting small lung cysts and/or end-expiratory flow limitation may be at risk of PBT. (+info)High aerobic capacities in the skeletal muscles of pinnipeds: adaptations to diving hypoxia. (7/538)
The objective was to assess the aerobic capacity of skeletal muscles in pinnipeds. Samples of swimming and nonswimming muscles were collected from Steller sea lions (Eumetopias jubatus, n = 27), Northern fur seals (Callorhinus ursinus, n = 5), and harbor seals (Phoca vitulina, n = 37) by using a needle biopsy technique. Samples were either immediately fixed in 2% glutaraldehyde or frozen in liquid nitrogen. The volume density of mitochondria, myoglobin concentration, citrate synthase activity, and beta-hydroxyacyl-CoA dehydrogenase was determined for all samples. The swimming muscles of seals had an average total mitochondrial volume density per volume of fiber of 9.7%. The swimming muscles of sea lions and fur seals had average mitochondrial volume densities of 6.2 and 8.8%, respectively. These values were 1.7- to 2.0-fold greater than in the nonswimming muscles. Myoglobin concentration, citrate synthase activity, and beta-hydroxyacyl-CoA dehydrogenase were 1.1- to 2. 3-fold greater in the swimming vs. nonswimming muscles. The swimming muscles of pinnipeds appear to be adapted for aerobic lipid metabolism under the hypoxic conditions that occur during diving. (+info)Functional and high-resolution computed tomographic studies of divers' lungs. (8/538)
OBJECTIVES: Several cross-sectional studies have described a decrease in the expiratory flow rates of divers. The objective of this study was to determine whether the combined application of high-resolution computed tomography (HRCT) and lung function testing supports the reported development of small airway obstruction in divers. METHODS: Thirty-two navy divers, 27 commercial divers, and 48 referents matched for age and smoking history underwent pulmonary function testing and HRCT of the lungs supplemented by a limited number of expiratory scans. The commercial divers were older and dived longer than the navy divers. Multivariate regression analysis was used to assess the relevant correlations of age, height, pack-years of cigarette smoking, and indices of diving exposure with lung function parameters. RESULTS: The inspiratory vital capacity and forced vital capacity (FVC) were greater, while the FEV% [(100 x FEV10)FVC] and maximum expiratory flow (MEF) at 25% (MEF25) of the FVC were lower for the navy divers than for the referents. The lung volumes and expiratory airflow pattern did not differ between the commercial divers and the corresponding referents. The forced expiratory volume in 1 second (FEV10), FEV%, MEF75, and MEF25 correlated negatively with the years of diving experience. This association was independent of age, height, and pack-years of cigarette smoking. For the majority of the divers and referents the expiratory HRCT revealed minor lobular air trapping without any difference between the groups. The HRCT did not show relevant morphologic abnormalities of small or large airways. CONCLUSIONS: The data confirm that diving may affect pulmonary function. However, there is no radiologic evidence for the development of small airway disease in these 2 subgroups of divers. (+info)Decompression sickness, also known as "the bends," is a medical condition that occurs when a person experiences a rapid decrease in atmospheric pressure, typically during scuba diving or high-altitude activities. The condition occurs when nitrogen gas dissolved in the blood and tissues of the body comes out of solution and forms bubbles, which can cause a range of symptoms and complications. The symptoms of decompression sickness can vary depending on the severity of the condition and the affected body. Common symptoms include joint pain and swelling, muscle cramps, fatigue, dizziness, and tingling or numbness in the extremities. In severe cases, decompression sickness can cause more serious complications, such as neurological problems, paralysis, and even death. Decompression sickness is typically treated with recompression therapy, which involves breathing pure oxygen in a pressurized chamber to allow the nitrogen bubbles to dissolve back into the bloodstream and tissues. Other treatments may include medication to relieve symptoms and physical therapy to help with joint pain and mobility.
In the medical field, decompression refers to the process of reducing or eliminating pressure on a body part or organ that has been subjected to increased pressure. This can occur in a variety of medical conditions, including: 1. Decompression sickness (also known as "the bends"): This occurs when a person breathes compressed air at high altitudes or during scuba diving, which can cause nitrogen bubbles to form in the body's tissues. Decompression sickness can cause symptoms such as joint pain, numbness, and paralysis, and requires immediate medical attention. 2. Decompression therapy: This is a treatment for decompression sickness that involves breathing pure oxygen to help the body eliminate the nitrogen bubbles that have formed. 3. Decompression illness: This is a broader term that encompasses both decompression sickness and arterial gas embolism, which occurs when air or other gases enter the bloodstream and travel to the lungs or other organs, causing damage. 4. Decompression surgery: This is a surgical procedure that is sometimes used to treat conditions such as spinal stenosis, where the spinal canal is narrowed and puts pressure on the spinal cord. The surgery involves removing a portion of the bone or other tissue that is compressing the spinal cord. Overall, decompression is an important process in the medical field that can help prevent or treat a variety of conditions related to increased pressure on the body.
Barotrauma is a medical condition that occurs when there is a difference in air pressure between the inside and outside of the body, causing damage to the body's tissues. It can occur when a person experiences a rapid change in altitude, such as during air travel or scuba diving, or when a person is exposed to high pressure in a confined space, such as in a pressurized aircraft or a hyperbaric chamber. Barotrauma can affect different parts of the body depending on the location of the pressure differential. For example, barotrauma of the ear is known as barotitis media and can cause pain, hearing loss, and balance problems. Barotrauma of the lungs is known as barotitis pulmonalis and can cause shortness of breath, chest pain, and coughing. Barotrauma of the sinuses is known as sinus barotrauma and can cause facial pain, headache, and congestion. Treatment for barotrauma depends on the severity of the condition and the affected area of the body. In some cases, the symptoms may resolve on their own, while in other cases, medical intervention may be necessary.
An embolism is a blockage in a blood vessel caused by a foreign substance, such as an air bubble, blood clot, or fat globule. An air embolism occurs when air enters the bloodstream and travels to a smaller blood vessel, where it can block blood flow and cause damage to the tissue or organ it is supplying. Air embolisms can occur in a variety of ways, including during medical procedures that involve the introduction of air into the bloodstream, such as an air injection or a chest tube insertion, or as a result of trauma to the body. Symptoms of an air embolism can include shortness of breath, chest pain, dizziness, and loss of consciousness. Treatment for an air embolism may involve medications to dissolve the air bubble or surgery to remove it.
In the medical field, the term "birds" typically refers to a class of warm-blooded vertebrates characterized by feathers, wings, and beaks. There are over 10,000 species of birds, and they can be found in a wide range of habitats, from forests and grasslands to deserts and oceans. In medicine, birds are sometimes studied as models for human diseases, particularly those related to infectious diseases. For example, some bird species, such as chickens and ducks, can carry and transmit viruses that are similar to those that affect humans, such as avian influenza. Birds are also used in medical research to study the effects of environmental pollutants on wildlife. For example, studies have shown that exposure to certain chemicals, such as pesticides and heavy metals, can have negative effects on bird populations. In addition, birds are sometimes used in medical treatments, such as in the field of avian therapy. Avian therapy involves the use of trained birds, such as parrots, to provide emotional support and companionship to people with a variety of conditions, including depression, anxiety, and dementia.
In the medical field, clothing refers to the garments worn by patients for various reasons, including comfort, hygiene, and protection. Clothing can also be used as a diagnostic tool to identify certain medical conditions or to monitor a patient's health status. For example, hospital gowns are commonly used in medical settings to provide patients with easy access to their bodies for medical procedures or to prevent the spread of infection. Wound dressings and compression stockings are also examples of medical clothing that are used to treat specific medical conditions. In some cases, clothing may also be used to manage symptoms of certain medical conditions, such as heat rash or eczema. For example, loose-fitting clothing made from breathable materials may be recommended for patients with heat rash, while patients with eczema may be advised to wear moisture-wicking clothing to prevent skin irritation. Overall, clothing plays an important role in the medical field, both in terms of patient care and in the diagnosis and treatment of medical conditions.
Drug hypersensitivity syndrome (DHS) is a severe and potentially life-threatening adverse reaction to certain medications. It is characterized by a combination of symptoms that can include fever, rash, lymphadenopathy (swelling of the lymph nodes), and internal organ involvement, such as liver or kidney damage. DHS is a type of immune-mediated reaction, meaning that the body's immune system mistakenly attacks the medication as if it were a foreign invader. This can lead to inflammation and damage to various organs and tissues throughout the body. DHS can occur with a wide range of medications, including antibiotics, anticonvulsants, and nonsteroidal anti-inflammatory drugs (NSAIDs). The onset of symptoms can occur anywhere from a few days to several weeks after starting the medication. Treatment for DHS typically involves discontinuing the medication that triggered the reaction and providing supportive care to manage symptoms and prevent complications. In severe cases, hospitalization and intensive care may be necessary.
Inert gas narcosis is a condition that occurs when a person is exposed to high concentrations of inert gases, such as nitrogen or helium, for an extended period of time. These gases can accumulate in the bloodstream and the body's tissues, leading to a variety of symptoms, including dizziness, confusion, disorientation, and loss of consciousness. Inert gas narcosis is most commonly associated with diving, as it can occur when a person breathes compressed air that contains high levels of nitrogen. The condition can also occur in people who work in enclosed spaces that are filled with inert gases, such as in the aerospace industry. Inert gas narcosis is a serious medical condition that can be life-threatening if not treated promptly. Treatment typically involves removing the person from the source of the inert gas and providing supportive care to manage the symptoms. In some cases, hyperbaric oxygen therapy may be used to help the body eliminate the excess inert gases from the bloodstream.
Drug eruptions refer to adverse reactions that occur on the skin or mucous membranes as a result of taking medication. These eruptions can range from mild rashes to severe, life-threatening reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Drug eruptions can be caused by a variety of medications, including antibiotics, anticonvulsants, nonsteroidal anti-inflammatory drugs (NSAIDs), and many others. It is important for healthcare providers to be aware of the potential for drug eruptions when prescribing medications and to monitor patients for any signs of an adverse reaction. If a drug eruption occurs, the medication should be discontinued and appropriate treatment should be provided to manage the symptoms and prevent complications.
Eosinophilia is a medical condition characterized by an increase in the number of eosinophils, a type of white blood cell, in the blood. Eosinophils are a type of granulocyte, which are immune cells that play a role in fighting off infections and parasites. Eosinophilia can be caused by a variety of factors, including allergies, parasitic infections, autoimmune disorders, and certain types of cancer. It can also be a side effect of certain medications, such as corticosteroids and some chemotherapy drugs. Eosinophilia can be classified as either absolute eosinophilia, which is an increase in the number of eosinophils in the blood regardless of the total number of white blood cells, or relative eosinophilia, which is an increase in the proportion of eosinophils to other types of white blood cells. Eosinophilia can be a sign of an underlying medical condition, and it is important to identify and treat the underlying cause in order to manage the symptoms and prevent complications. Treatment may involve medications to reduce inflammation or to target the underlying cause of the eosinophilia, as well as supportive care to manage symptoms.
Breath holding is a behavior in which an individual voluntarily stops breathing for a period of time. It is a common behavior in infants and young children, and is often a normal part of their development. However, in some cases, breath holding can be a symptom of a medical condition or a response to stress or anxiety. In medical terms, breath holding is classified as either primary or secondary. Primary breath holding is a normal behavior that occurs in infants and young children as they learn to control their breathing. Secondary breath holding, on the other hand, is a response to a specific stimulus or situation, such as pain, fear, or frustration. Breath holding can also be a symptom of certain medical conditions, such as epilepsy, autism spectrum disorder, and Prader-Willi syndrome. In these cases, breath holding may be more frequent or prolonged than is typical for a healthy individual. If you are concerned about breath holding in yourself or a loved one, it is important to speak with a healthcare provider. They can help determine the underlying cause of the breath holding and recommend appropriate treatment.
High Pressure Neurological Syndrome (HPNS) is a condition that occurs when the pressure inside the skull becomes too high, leading to damage to the brain. This can happen when the pressure inside the skull increases rapidly, such as during a rapid increase in altitude, or when the pressure inside the skull remains high for an extended period of time, such as in cases of head injury or brain tumor. Symptoms of HPNS can include headache, nausea, vomiting, dizziness, confusion, and loss of consciousness. In severe cases, HPNS can lead to permanent brain damage or death. Treatment for HPNS typically involves reducing the pressure inside the skull, either by administering medication or by performing surgery to relieve the pressure. In some cases, treatment may also involve oxygen therapy or other supportive measures to help the body cope with the effects of high altitude.
Apnea is a medical term that refers to a temporary cessation of breathing. It can occur in both children and adults and can be caused by a variety of factors, including sleep disorders, respiratory problems, and neurological conditions. In medical settings, apnea is typically diagnosed through a sleep study, which involves monitoring a person's breathing patterns while they sleep. There are different types of apnea, including obstructive sleep apnea, central sleep apnea, and mixed sleep apnea. Obstructive sleep apnea occurs when the airway becomes blocked during sleep, preventing air from flowing in and out of the lungs. Central sleep apnea occurs when the brain fails to send signals to the muscles that control breathing, leading to pauses in breathing. Mixed sleep apnea is a combination of both obstructive and central sleep apnea. Untreated sleep apnea can lead to a range of health problems, including high blood pressure, heart disease, stroke, and diabetes. Treatment options for sleep apnea may include lifestyle changes, such as weight loss and quitting smoking, as well as the use of continuous positive airway pressure (CPAP) machines or other medical devices to help keep the airway open during sleep.
