Study findings do not support routine use of oxygen therapy in all patients with heart attack symptoms Oxygen is a blood vessel constrictor or vasoconstrictor. As blood vessels are constricted, circulation in the peripheral blood vessels is significantly reduced, an effect that was previously thought to increase the risk of stroke.
Making the world better, one answer at a time. The magnets in speakers work to absorb the sounds running through the coils. Think of it as a big dust collector and the dust in the sound coming through.n speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm.
Inside the scanner are coils of metallic wire. When electricity passes through the coils, a magnetic field is created and the coils vibrate. The sound the MRI makes is the metal coils vibrating and banging together inside the machine, creating a very strong magnetic field.The sound may reach up to 100 Decibels, so patients are required to use ear protection. We also have a sound system so the patient may enjoy music through headphones while being scanned.he sound the MRI makes is the metal coils vibrating and banging together inside the machine, creating a very strong magnetic field.
