heat (redirected from On heat)

heat (hēt)

1. the sensation of an increase in temperature.

2. the energy producing such a sensation; it exists in the form of molecular or atomic vibration and may be transferred, as a result of a gradient in temperature. Symbol Q or q.

3. to become, or to cause to become, warmer or hotter.

conductive heat  heat transmitted by direct contact, as with a hot water bottle.

convective heat  heat conveyed by currents of a warm medium, such as air or water.

conversive heat  heat developed in tissues by resistance to passage of high-energy radiations.

prickly heat  miliaria rubra.

heat (ht)

n.

1. A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.

2. The sensation or perception of such energy as warmth or hotness.

3. An abnormally high bodily temperature, as from a fever.

4. Estrus.

heat/cold application,

a nursing intervention from the Nursing Interventions Classification (NIC) defined as stimulation of the skin and underlying tissues with heat or cold for the purpose of decreasing pain, muscle spasms, or inflammation. See also Nursing Interventions Classification.

heat,

n the state of a body or of matter that is perceived as being opposite of cold and is characterized by elevation of temperature.

heat, applied,

n the therapeutic application of wet or dry heat to increase circulation and produce hyperemia, accelerate the dissolution of infection and inflammation, increase absorption from tissue spaces, relieve pain, relieve muscle spasm and associated pain, and increase metabolism.

heat, applied, and cold,

n the most commonly employed physical agents in dental practice; they modify the physiologic processes and have both a systemic and a local effect. The principal effect on the tissues is mediated by the alteration in the circulatory mechanisms. Properly used, they have a salutary therapeutic result; improperly used, they may produce serious pathologic consequences.

heat, applied, contraindications,

n.pl the conditions that preclude the use of heat application: peripheral neuropathy, conditions in which maximum vasodilation and inflammation are already present, acute inflammatory conditions in which more swelling will cause acute pain and pulpitis, septicemia, and malignancies.

heat, applied, general physiologic effects,

n.pl the physiologic effects of generally applied wet or dry heat; increase in body temperature, generalized vasodilation, rise in metabolism, decrease in blood pressure, increase in pulse rate and circulation, and increase in depth and rate of respiration.

heat, applied, local physiologic effects,

n.pl the physiologic effects of locally applied wet or dry heat to the intraoral or extraoral tissues: increase in caliber and number of capillaries, increased absorption resulting from capillary dilation, increased lymph formation and flow, relief of pain, relief of spasm, increase of phagocytes, and a rise in local metabolism.

heat loss, metabolic causes,

n.pl the biologic factors that influence heat loss: redistribution of blood vasodilation and vasoconstriction, variations in blood volume, tendency of fat to insulate the body, and evaporation.

Patient discussion about On heat.

Q. Depression related. How can one prevent another from acting in the heat of the moment? I've known a friend who has struggled with personal depression most of his life, and every once in a while it really gets to him (yesterday, for example). Usually he can try to brush it off by occupying himself with something else, but other times he can't, and ends up seriously considering things that he normally wouldn't; suicide being the most serious. I talked to him today, and he told me he felt fine, but I'm concerned that one day he might actually act on his feelings.

A. My suggestion is to keep frequent contact with your friend and keep them talking and sharing their problems and worries. Someone who may often think about suicide should not be left alone if that is possible, especially when there are those really dark days.

Someone needs to followup and make sure they take their medication. Its so easy to lapse on that. My wife keeps up with me, but sometimes, we both miss it. I have resorted to programming the appoinment calendar on my cell phone PDA to alert me twice a day at medicine time. That only works if I remember to turn the phone on.
My doctor provided me with additioanl medication for those bad days which really works. It usually makes me sleepy and soon I forget about the whole thing that seemed to be bothering me. Thise bad days pass and soon all is back on track. Its just soemthing I have learned to live with for many many years. There's not going to be a cure for me. I just do the best I can and let the chips fall where they may.

Q. i suffer from upper and lower back pain , and i use this heating pills and it does not do a thing !!! i paid a 50$ bucks for those and my back still hurts like hell ! what can i do to make it go away , or at least ease the pain by a bit ????

A. Low back pain is very very common. The best solution is to combine mellow physical activity (streching, walking, swimming) on a daily basis, with creams that have anti pain ingredients during extreme pain. If the pain is continuous you should see a doctor for some further evaluation.

Q. Is ligament heating better than an arthroscopic surgery? I have a partial tear in my left knee (acl) and they wanna operate on me. I heard heating it can solve the problem. is it true?

A. i never heard of "ligament heating" from what i know- ligament has limited ability to regenerate. if partially torn it may need only physiotherapy and care. but if it's torn more then it can heal by itself- you need surgery. this is why there's orthopedics- to evaluate the situation, give you a diagnosis and the recommended treatment. it's always good to second guess because they are only human. you can ask other orthopedics and see what they say.
