The No-Panic Syndromes in Underwater Diving
The Physician and Sportsmedicine
|January 3, 2018
Summary
No-panic syndromes cause most breath-hold diving fatalities. These syndromes lead to sudden underwater blackout without warning, emphasizing the need to identify causes for proper diver treatment and prevention.
Area of Science:
- Physiology
- Diving Medicine
- Emergency Medicine
Background:
- No-panic syndromes are the leading cause of death in breath-hold diving.
- These syndromes are characterized by sudden loss of consciousness underwater, termed blackout.
- Blackout occurs without preceding panic or struggle for air.
Purpose of the Study:
- To review the pathophysiology of underwater blackout.
- To identify and list the various etiologies of no-panic syndromes.
- To underscore the importance of diagnosing blackout causes for diver treatment.
Main Methods:
- Literature review on breath-hold diving physiology and incidents.
- Analysis of reported cases of underwater blackout.
- Compilation of known causes contributing to no-panic syndromes.
Main Results:
- No-panic syndromes are the primary cause of breath-hold diving fatalities.
- Underwater blackout is defined by rapid loss of consciousness.
- Over a dozen distinct etiologies contribute to these syndromes.
Conclusions:
- Identifying the specific cause of each underwater blackout is crucial.
- Proper diagnosis enables targeted treatment and prevention strategies for divers.
- Understanding blackout pathophysiology can improve diver safety and reduce mortality.

01:27Panic Disorder
839
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

01:24Nephrotic Syndrome I : Introduction
702
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

1.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

1.2K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

595
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
