Introduction: Pulmonary fluid shifts can occur while scuba diving. Such shifts, generally thought to be rare, may result in a life-threatening phenomenon known as immersion pulmonary edema (IPE). This study aims to better classify the normal physiology of diving using ultrasound (US) to determine if these fluid shifts occur routinely during commercial diving work at the NASA Neutral Buoyancy Laboratory (NBL). Methods: Chest US was performed on commercial divers prospectively pre- and post-dive to evaluate the presence of B-lines in a total of 12 intercostal points on the anterior, posterior, and lateral chest wall...

BACKGROUND: Scuba diving activities expose divers to serious accidents, which can require early hospitalization. Helicopters are used for early evacuation. On the French Mediterranean coast, rescue is made offshore mainly by a French Navy Dauphin or at a landing zone by an emergency unit EC 135 helicopter. METHODS: We retrospectively analyzed diving accidents evacuated by helicopter on the French Mediterranean coast from 1 September 2014 to 31 August 2016. We gathered data at the Center for Hyperbaric Medicine and Diving Expertise (SMHEP) of the Sainte-Anne Military Hospital (Toulon, France), the 35 F squadron at Hyres (France) Naval Air Station, and the SAMU 83 emergency unit (Toulon, France)...

Drowning is "the process of experiencing respiratory impairment from submersion or immersion in liquid". According to WHO, drowning claim the lives of more than 40 people every hour of every day. Drowning involves some physiological principles and medical interventions that are unique. It occurs in a deceptively hostile environment that involves an underestimation of the dangers or an overestimation of water competency. It has been estimated that more than 90% are preventable. When water is aspirated into the airways, coughing is the initial reflex response...

INTRODUCTION: Cold-induced vasodilation (CIVD) is seen in the extremities during exposure to cold. A strong vasodilation response has been associated with a decreased risk of cold injury. Increasing CIVD might further decrease this risk. The calcium-channel blocker nifedipine causes vasodilation and is used to treat Raynaud's syndrome and chilblains. Nifedipine is also used for high altitude pulmonary edema and could potentially serve a dual purpose in preventing frostbite. The effects of nifedipine on CIVD have not been studied...

Swimming-induced pulmonary edema (SIPE), also called immersion pulmonary edema (IPE), is a medical condition seen in various water-based activities such as scuba diving, swimming, aqua jogging, triathlete competition and snorkeling. It occurs when transcapillary filtration of low protein fluid collects in the lungs, in the absence of water aspiration during an aquatic activity, causing acute dyspnea, cough and/or hemoptysis. The hallmark of this entity is the complete resolution of symptoms within 48 hours...

Immersion pulmonary edema (IPE) is a rare condition observed in divers. We report a case of a 66-year-old man on maintenance dialysis who developed acute dyspnea and blood-tinged sputum after scuba diving. Vital signs on admission were significant for elevated blood pressure at 209/63 mmHg and hypoxia with an oxygen requirement of 6 L/min. Physical examination was remarkable for bilateral coarse crackles and systolic ejection murmur. Chest radiography revealed bilateral pulmonary edema. Echocardiography showed aortic stenosis and diffuse hypokinesis of left ventricular wall motion...

Background: Immersion can cause immersion pulmonary edema (IPE) in previously healthy subjects. We performed a case-control study to better identify IPE risk factors. Methods: We prospectively included recreational scuba divers who had presented signs of IPE and control divers who were randomly chosen among diving members of the French Underwater Federation. We sent an anonymous questionnaire to each diver, with questions on individual characteristics, as well as the conditions of the most recent dive (controls) or the dive during which IPE occurred...

COMMENT

Immersion pulmonary (IPE, also known as swimming-induced pulmonary edema, SIPE) is a condition in which pulmonary edema develops rapidly during a dive or vigorous swim. Symptoms include dyspnea and hemoptysis. Physical exam reveals typical signs of bilateral pulmonary edema, which can be confirmed radiographically or with bedside ultrasound.

Fran de Asís Fernández, Lara Rodríguez-Zamora, Erika Schagatay
To facilitate recovery from hypoxia, many freedivers use a breathing method called "hook breathing" (HB) after diving, involving an interrupted exhale to build up intrapulmonary pressure. Some divers experience a delay in recovery of arterial oxygen saturation (SaO2 ) after diving, interpreted as symptoms of mild pulmonary edema, and facilitated recovery may be especially important in this group to avoid hypoxic "blackout." We examined the influence of HB on recovery of SaO2 in freedivers with slow recovery (SR) and fast recovery (FR) of SaO2 after deep "free immersion" (FIM) apnea dives to 30 m depth...

IMPORTANCE: Immersion pulmonary edema (IPE) is a rare but important complication associated with surface swimming and underwater diving. It tends to reoccur and can be fatal. It is not very well-known to clinicians involved in the care of individuals participating in aquatic activities. We performed a systematic review of immersion pulmonary edema to describe the condition and provide guidelines for its management. EVIDENCE REVIEW: We searched PubMed to identify case reports and studies using the MeSH terms "immersion," "pulmonary edema," "cold-induced," "exercise," "hemodynamics," "water immersion,'' "cardiovascular response," alone and in combinations...

With the growing popularity of water-based sports, cases of swimming-induced pulmonary edema (SIPE) are becoming increasingly recognized. SIPE, a potentially life-threatening condition, is an acute cause of breathlessness in athletes. It has been described frequently in scuba divers, swimmers, and triathletes and is characterized by symptoms and signs of pulmonary edema following water immersion. It is important to recognize that athletes' symptoms can present with a spectrum of severity from mild breathlessness to severe dyspnea, hemoptysis, and hypoxia...

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...
