Yes but not always . Recent developments in in 2013 in America, Japan and Australia have meant that clinically dead people from 1 to 3 hours have been resurrected after cardiac arrest using mechanical CPR combined with ECMO treatment( extracorporeal membrane oxygenation - an artificial lung hat keeps oxygen and blood flowing to the brain and vital organs) . A new machine called "Äuto Pulse" uses a band that wraps around and squuezes the entire chest providing precise and consistent compressions.

Brain death is a different matter. Once someone has no activity in the brain stem or brain they are technically dead .However you can revive the body and keep it alive on a life support system BUT the person is considered dead. Keeping a body alive is occassionally done in order to be able to harvest organs or in unusual circumstances to keep a viable environment for a fetus to allow it to continue to develop until it is ready to be born when the mother has died.

Generally while health care professionals will do their best to revive someone, even then the success rate is low. Typically they'll perform CPR as long as needed or until a doctor call the time of death. But during CPR the brain is still being deprived of oxygen so if the person does survive they often have varying levels of brain damage.

The determination of death has always been a problem. In times prior to the 19th century a "'wake" was conducted for the dead. A wake is a period of lasting from 3 to 14 days so that people could observe the body to see if the victim was really dead rather than comatose. This was more than enough time for decomposition to set in which is absolute proof of death. Once decomposition begins ressurection is impossible.

Early morticians would often perform "tests" on the apparent cadavers, either something painful that might cause a response, or some act that would make sure the subject was truly dead.

In the 1980's the call on death was no EKG and flat EEG, or cessation of breathing for over 9 minutes or so. However, this wasn't always reliable either.

Sudden immersion in ice-water sometimes causes "diving reflex" to activate and victims can in rare instances be revived after appearing clinically dead . This is thought to be akin to the reflexive reaction marine mammals experience when they dive deeply and remain submerged for as much as an hour or more. During this time, blood transfuses, body processes decline sharply, breathing stops, and pulse can drop as low as 3 beats per minute, or less. In humans, the likelihood of diving reflex kicking in is dramatically improved with the coldness of the water, the youth of the victim, and the face being immersed.

You cannot voluntarily activate your spit glands. When you put food in your mouth, they automatically begin to produce saliva to aid in the digestion of food. Sometimes just thinking about eating food can allow them to produce saliva.

Yes it can. It depends on the amount of voltage that you got shocked with.

Electric shock can put the heart into asystole (absence of heart contractions). The heart will often resume its rhythm, but the accomanying respiratory arrest lasts longer, and can then lead to a second cardiac arrest due to lack of oxygen.

Also, all electrical burns are considered to be worse than look externally (they can burn internally as well).

Alcohol is quite volatile, and will evaporate very easily -- far moreso than water. So if the alcohol packing is in any way compromised, even microscopically, you'll find dry pads in the pack. And this is a frequent occurrance.

However, maintained in sealed stated, I don't see a way that alcohol can decompose -- so no.

Low-adherence dressings (e.g. Mepitel®, Jelonet®) are used as interface layers and secondary absorbent dressings. They vary from impregnated cotton or viscose fibres to fenestrated silicone dressings, and help to make dressing changes less painful.Vapour-permeable films and membranes (e.g. Opsite®, Tegaderm®) allow the passage of water vapour and oxygen, but not water or microorganisms. They are commonly used to cover acute surgical wounds, but are not suitable for heavily exuding wounds.Odour-absorbent dressings (e.g. Carboflex®, Lyofoam C®) contain activated charcoal to neutralise odours. They are used mainly in the chronic setting for malodorous infected or fungating wounds.Hope this helps!

Rib fractures are not very common but not unheard of either. As they are surrounded by lots of strong muscle, it takes quite a force to abuse them. A rib fracture/crack can be caused by a fall, getting hit by a car, or from extremely forceful coughing (i.e. due to pneumonia).

Complications can occur when the fracture breaks apart completely in half. The sharp surface is likely to protrude the surrounding organs, namely the lungs.

Some signs and symptoms of a fractured/cracked ribs include:

1. Severe sharp pain in the chest area worsened by taking a breath in.

2. History of recent trauma to the area.

3. Swelling and tenderness around the rib are (this may include that back).

4. Deviation/asymmetry of the chest area, especially when taking a breath in.

5. Crepitus (grinding and crunching sound due to the bone ends making contact)

6. Nausea and Vomiting.

7. Shortness of Breath.

8. Coughing up blood.

9. Chest wall deformity.

10. Severe pain on movement.

The treatment for a rib fracture follows the general rules for treating fractures. Immobilise the patient by telling him/her to limit movement.

Call for an ambulance or have the patient dispatched to hospital immediately in case any complications arise.

Lean the patient towards the side of the injury so that any fluid can drain and not affect the surrounding area.

Continue to reassure the patient and advise her of what you are doing and how it will help.

In rare cases, the fractured rib may protrude completely and break the surface of the skin. In this instance, control any external bleeding by applying a sterile dressing around the protrusion and padding over the bone.

Provided you are qualified, a pre-hospital analgesic may be used. Effective analgesics in this case include entonox (nitrous oxide), methoxyflurane or morphine.

Always assume that complications are present and have the patient checked by medical professionals.

You can find the pulse on the body either on the wrist or the neck. When checking for the pulse on the wrist you make sure you are checking on the side of the thumb using your pointer finger and middle finger. When you are checking on the neck (using the pointer finger and middle finger as well) take you fingers and go from the ear towards your chin. You will feel a little indenct on the neck but under the jaw. You should be able to feel the pulse in that area.

Abrasion is caused by friction or rubbing of the skin with a rough surface. Rug burns and board burns are also examples of abrasion, because they are caused by friction.

Depending on the severity, the bone would need to be placed back in it's original position. It would then have to be set in a cast, hard or soft. Making sure that the bones are in a comfortable position, helps the them heal quicker and gentler.

Probably somewhere easily accessible- for instance, if you live in a multilevel house, I would keep mine on the main or lower level. This way, in case of a fire, you wouldn't have to rush up any staircases, which can be dangerous. If it is a very large fire, I would let the medics take care of that.It also depends on where you live. I would contact a local first aid specialist if you want specifically pertaining information.

The average healthy person has approximately 6 litres / 12 pints of blood - loss of one third, (1/3), of the total blood volume is fatal. Therefore I would say that a loss of about a litre / 2 pints would render a healthy person unconscious.

There is no true antidote for gasoline ingestion. The first thing you should do is call 911. Once 911 has dispatched an ambulance, call Poison Control (in the US, 1-800-222-1222) and follow their instructions.

The treatment is mainly supportive in nature as you have to wait for the hydrocarbons to clear your system.

Ammonium nitrate crystals and water. When you pop the water pack, the two undergo an endothermic reaction, forming ammonium and nitrate ions (NH4+ & NO3-). Water breaks the two parts of NH4NO3 into the positive and negative parts, and it takes heat energy from the surrounding area to make the separation. When it dries it recombines and releases that heat (not observed because water gets colder when it evaporates). So if you CAREFULLY cut that bag open and dry it, it will do the same thing again. I wouldn't want to eat the crystals or the end liquid. plant fertilizers don't make good food.
