Damage to the sinuses usually resulting in pain, and often burst blood vessels and nosebleed. [33] Obstruction to the sinus ducts leading to pressure differences between the interior of the sinus and the external pressure. [33] Do not dive with conditions such as the common cold or allergies that cause nasal congestion. [33]
Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
During inspiration, the high positive pressures in the pulmonary blood vessels pushing out are met by negative pressures distending the blood vessel and placing increased stress on the walls. Studies in vitro show that significant disruption of the pulmonary capillaries occurs at pressures of approximately 80 mmHg.
Furthermore, she adds, “foods like pomegranate seeds and beets increase a compound in the blood called nitric oxide, which dilates blood vessels to allow more blood flow,” Dr. Denniston says.
"Lipid-rich plaques build up over time and can decrease blood flow through the blood vessel, or the plaque can rupture, causing a blood clot which shuts down the blood vessel and restricts blood ...
Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. [1] Bleeding can occur internally , or externally either through a natural opening such as the mouth , nose , ear , urethra , vagina or anus , or through a puncture in the skin .
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the ...
Blast lung refers to severe pulmonary contusion, bleeding or swelling with damage to alveoli and blood vessels, or a combination of these. [6] It is the most common cause of death among people who initially survive an explosion.
