Unconsciousness should occur pretty quickly with a GSW to the pulmonary artery, but death certainly wouldn't be instantaneous.
Despite what you see in movies, on TV and in Video Games, even a GSW to the noggin (head) doesn't cause instant death. The person may drop and never make a purposeful movement again, but the dying process isn't like flipping a light switch. Its more like flipping 40-50 light switches over a few minutes.
They may cause death if they block a major artery, such as the large pulmonary artery that runs through the lungs. They also may cause tissue to die if they prevent blood flow to the area.
The pulmonary artery is the one which carries blood from the right ventricle to the lungs. It is the only artery in the body that carries deoxygenated blood. The blood is carried at a pressure, usually less than 30mmHg. So, if the pulmonary artery was to be cut and bleed, the person would die when blood volume fell below the minimum necessary. This wouldn't take long, either. Between actual blood loss, and the sudden decrease in pressure such an injury would cause death in approximately 2 minutes
Death
A Pulmonary Infarction is the death of a small area of lung resulting from pulmonary embolism. It occurs in a small, dead-end pulmonary artery and often causes pain in the back or chest.PI is an an infrequent consequence of Pulmonary Edema(< 10% of cases). It is sometimes due to thrombosis in situ of the pulmonary arteries as might occur in congenital heart disease associated with severe pulmonary hypertension or in hematologic disorders (eg, sickle cell anemia).
There is no guaranteed instant death if a person gets shot in the head. The severity and location of the injury, as well as immediate medical intervention, can significantly impact the outcome. In some cases, a gunshot to the head can be fatal, but in others, individuals may survive with varying degrees of injury.
I believe flying directly into the sun would cause instant death.
Any severed vein or artery can cause you to bleed to death
a gunshot
There are quite a few toxins that can cause instant death such as gephyrotoxin. Histrionicotoxin is another very toxic chemical.
