If the bicuspid valve does not close completely, blood can flow backwards into the heart. This is regurgitation, also called aortic valve insufficiency. The heart then must pump that same blood out again, causing strain on the heart's lower left chamber, the left ventricle.
Answer:
An audiometry that assesses the airway and nerve at the same time.
When a person has hearing impairment, will be seen a fall in the audiometric graph both at the level of the bone or neurological pathway above 30 decibels and 250 hertz.
Ice can cause hypothermia.
Ice can cause vasoconstriction
Ice can reduce blood flow to the burned area.
<h3>What are the reasons to avoid use of ice on burned body parts ?</h3>
Ice can result in hypothermia, which reduces blood flow to the burned area and causes the burned part to cool excessively. Ice has the potential to shrink the blood vessels supplying injured skin, resulting in a reduction in the amount of blood and oxygen delivered to the area.
- Applying ice does not stop further tissue damage; instead, it reduces blood flow, delaying the healing of the wound. Ice actually reduces blood flow owing to vasoconstriction, rather than increasing it, to the burned area.
