BACKGROUND: Immersion pulmonary edema is potentially a catastrophic condition; however, the pathophysiological mechanisms are ill-defined. This study assessed the individual and combined effects of exertion and negative pressure breathing on the cardiovascular system during the development of pulmonary edema in SCUBA divers. METHODS: Sixteen male professional SCUBA divers performed four SCUBA dives in a freshwater pool at 1 m depth while breathing air at either a positive or negative pressure both at rest or with exercise...

BACKGROUND: The risk factors of pulmonary edema induced by diving in healthy subjects are not well known. The aim of the present study was to assess the parameters contributing to the increase in extravascular lung water after diving. METHODS: This study was carried out in a professional diving institute. All divers participating in the teaching program from June 2012 to June 2014 were included in the study. Extravascular lung water was assessed using the detection of ultrasound lung comets (ULC) by chest ultrasonography...

Immersion pulmonary edema may occur during scuba diving, snorke-ling or swimming. It is a rare and often recurrent disease, mainly affecting individuals aged over 50 with high blood pressure. However it also occurs in young individuals with a healthy heart. The main symptoms are dyspnea, cough and hemoptysis. The outcome is often favorable under oxygen treatment but deaths are reported. A cardiac and pulmonary assessment is necessary to evaluate the risk of recurrence and possible contraindications to immersion...

Immersion Pulmonary Edema (IPE) reduces the transport of gases over the respiratory membrane due to edema in the interstitium and respiratory zones. IPE has previously been described in both swimmers and divers, with a few known fatal cases. We have reviewed 42 SCUBA and snorkeling-related drowning deaths, and through a thorough analysis of each case, including both diving physiology and forensic pathology, we present IPE as a differential diagnosis to drowning in four cases. Our findings propose that; absence of watery content in the stomach and conducting airways, and liquid filled lungs without hyperexpansion, may be compatible with IPE...

Swimming-induced pulmonary edema (SIPE) occurs during swimming and scuba diving, usually in cold water, in susceptible healthy individuals, especially military recruits and triathletes. We have previously demonstrated that pulmonary artery (PA) pressure and PA wedge pressure are higher during immersed exercise in SIPE-susceptible individuals versus controls, confirming that SIPE is a form of hemodynamic pulmonary edema. Oral sildenafil 50 mg 1 h before immersed exercise reduced PA pressure and PA wedge pressure, suggesting that sildenafil may prevent SIPE...

Although the lungs are a critical component of exercise performance, their response to exercise and other environmental stresses is often overlooked when evaluating pulmonary performance during high workloads. Exercise can produce capillary leakage, particularly when left atrial pressure increases related to left ventricular (LV) systolic or diastolic failure. Diastolic LV dysfunction that results in elevated left atrial pressure during exercise is particularly likely to result in pulmonary edema and capillary hemorrhage...

Immersion pulmonary edema (IPE) is a misdiagnosed environmental illness caused by water immersion, cold, and exertion. IPE occurs typically during SCUBA diving, snorkeling, and swimming. IPE is sometimes associated with myocardial injury and/or loss of consciousness in water, which may be fatal. IPE is thought to involve hemodynamic and cardiovascular disturbances, but its pathophysiology remains largely unclear, which makes IPE prevention difficult. This observational study aimed to document IPE pathogenesis and improve diagnostic reliability, including distinguishing in some conditions IPE from decompression sickness (DCS), another diving-related disorder...

Water covers over 70% of the earth, has varying depths and temperatures and contains much of the earth's resources. Head-out water immersion (HOWI) or submersion at various depths (diving) in water of thermoneutral (TN) temperature elicits profound cardiorespiratory, endocrine, and renal responses. The translocation of blood into the thorax and elevation of plasma volume by autotransfusion of fluid from cells to the vascular compartment lead to increased cardiac stroke volume and output and there is a hyperperfusion of some tissues...

The cardiac effects of aquatic sports have increased in interest with the experience of cardiac responses to swimming and diving. The syndrome of swimming-induced pulmonary edema is likely caused by a combination of central blood shifts, sudden onset of high exercise demands, and impaired diastolic relaxation of the left ventricle. Divers also develop venous gas emboli caused by nitrogen supersaturation in blood and tissues during ascent from depth. The physiology and physics of water immersion and diving are unique...

Drowning is a leading cause of accidental death worldwide and its diagnosis is an important part of forensic investigation. It is generally acknowledged that hypoxia due to airway obstruction by fluid is the primary mechanism of death in drowning. Drowned individuals are usually found dead in the water or show severe clinical signs once out of the water. However, sudden death due to drowning after a short period of recovery following immersion/submersion has rarely been reported. A case of a 40-year-old man who died suddenly due to severe pulmonary edema about 40 min after he was recovered from an episode of immersion is reported...

PURPOSE: Immersion pulmonary edema (IPE) occurs in swimmers (especially triathletes) and scuba divers. Its pathophysiology and risk factors are incompletely understood. This study was designed to establish the prevalence of preexisting comorbidities in individuals who experience IPE. METHODS: From 2008 to May 2010, individuals who had experienced IPE were identified via recruitment for a physiological study. Past medical history and subject characteristics were compared with those available in the current body of literature...

Immersion pulmonary oedema (IPE) is being increasingly recognized in swimmers, snorkellers and scuba divers presenting with acute symptoms of respiratory distress following immersion, but fatal case reports are uncommon. We report two fatal cases of probable IPE in middle-aged women, one whilst snorkelling and the other associated with a scuba dive. In the snorkeller's case, an episode of exercise-related chest tightness and shortness of breath that occurred 10 months previously was investigated but this proved negative, and she was on no medications...

BACKGROUND: High-altitude pulmonary edema (HAPE) and immersion pulmonary edema (IPE) are potentially life-threatening conditions that affect athletes, including high-altitude climbers, long-distance swimmers, and underwater divers. The objectives of this study were to measure lung density (before and after exercise) and quantify the pulmonary lymphatic network in individuals susceptible and resistant to HAPE/IPE. METHODS: Eighteen male (N = 10) and female (N = 8) subjects were recruited...

It is well known that immersion pulmonary edema can be life-threatening for divers using a self-contained underwater breathing apparatus (scuba). Swimming-induced pulmonary edema in otherwise healthy individuals is not an object of dispute but its real severity is not well known and is probably underestimated. We report two cases of life-threatening acute respiratory distress while swimming and snorkeling, one of which is well documented for swimming-induced pulmonary edema. The interest of these case reports lies in the suddenness of these life-threatening events...

INTRODUCTION: Aquagenic palmoplantar keratoderma (APK) is a cutaneous phenomenon marked by the formation of edematous, translucent papules and plaques on the palms after water immersion. It can be observed in healthy subjects, but while this dermatosis is little known by practitioners treating these patients, most cases of APK have been described in patients with cystic fibrosis (CF). The primary objective of this study was to evaluate the frequency of APK in a population of children with CF...

Recreational scuba diving is a popular leisure activity with the number of divers reaching several millions worldwide. Scuba diving represents a huge challenge for integrative physiology. In mammalian evolution, physiological reflexes developed to deal with lack of oxygen, rather than with an excess, which makes adaptations to scuba diving more difficult to describe and understand than those associated with breath-hold diving. The underwater environment significantly limits the use of equipment to register the organism's functions, so, in most instances, scientific theories are built on experiments that model real diving to some extent, like hyperbaric exposures, dive reflexes or water immersion...

Assessment of lung growth is a critical component of the perinatal autopsy. Increased lung liquid content may lead to overestimation of lung growth based on (wet) lung weight. In contrast, lung volume is not influenced by intraalveolar lung liquid. Our aim was to establish age-specific reference values for postmortem lung volume/BW in preterm and term infants. We performed a retrospective analysis of fetuses/infants (16-41 weeks' gestation) without (N = 134) or with (N = 79) risk factors for pulmonary hypoplasia...

Immersion pulmonary edema in scuba divers is a rare disorder that tends to recur and can be potentially fatal, even in the absence of underlying cardiac disease. Anecdotal cases of reversible myocardial dysfunction have been described in this setting, but little is known of its pathogenesis. The purpose of the present study was to determine the clinical outcomes and the determinants associated with this condition. The data from 54 consecutive divers admitted for acute immersion pulmonary edema during a 5.5-year period were retrospectively studied...
