time

 [tīm]
a measure of duration. See under adjectives for specific times, such as bleeding time.
activated partial thromboplastin time (APTT, aPTT) the period required for clot formation in recalcified blood plasma after contact activation and the addition of platelet substitutes such as brain cephalins or similar phospholipids; used to assess the coagulation pathways. A prolonged aPTT can indicate a deficiency of any of various coagulation factors, including factors XII, XI, IX, VIII, X, V, and II, and fibrinogen.
AEC minimal response time the shortest duration at which x-ray exposure can be terminated by automatic exposure control.
atrioventricular sequential time a fixed nonprogrammable interval that extends from the atrial stimulus to the ventricular stimulus.
bleeding time the time required for a standardized wound to stop bleeding; used as a test for platelet disorders; see also bleeding time.
circulation time the time required for blood to flow between two given points; see also circulation time.
clotting time (coagulation time) the time required for blood to clot in a glass tube; see also clotting.
cold ischemia time the time between the placement of a traumatically amputated body part in ice and the time of surgical replantation.
inertia time the time required to overcome the inertia of a muscle after reception of a stimulus.
ischemia time the total time between traumatic amputation of a limb or portion of a limb and its surgical reimplantation; it is the sum of warm and cold ischemia times.
minimal response time in radiology, the shortest possible exposure time for an x-ray film to be exposed automatically.
one-stage prothrombin time prothrombin time.
prothrombin time see prothrombin time.
real time a term used to describe a recording device that shows events simultaneously to their occurrence.
thrombin time the time required for plasma fibrinogen to form thrombin; see also thrombin time.
warm ischemia time the time interval between traumatic amputation of a limb or part and its placement on ice.

time

(tīm) a measure of duration. Symbol t.
activated partial thromboplastin time  (APTT) (aPTT) (PTT) the period required for clot formation in recalcified blood plasma after contact activation and the addition of platelet substitutes; used to address the intrinsic and common pathways of coagulation.
bleeding time  the duration of bleeding after controlled, standardized puncture of the earlobe or forearm; a relatively inconsistent measure of capillary and platelet function.
circulation time  the time required for blood to flow between two given points.
clotting time , coagulation time the time required for blood to clot in a glass tube.
inertia time  the time required to overcome the inertia of a muscle after reception of a stimulus from a nerve.
one-stage prothrombin time  prothrombin t.
prothrombin time  (PT) the rate at which prothrombin is converted to thrombin in citrated blood with added calcium; used to assess the extrinsic coagulation system of the blood.
reaction time  the time elapsing between the application of a stimulus and the resulting reaction.
stimulus-response time  reaction t.
thrombin time  (TT) the time required for plasma fibrinogen to form thrombin, measured as the time for clot formation after exogenous thrombin is added to citrated plasma.

time chart
a graph on which the values of a variable are plotted on one axis and time on the other.
time cluster
a cluster of cases at particular points along a time axis.
developing time
for an x-ray film is about 3 to 5 minutes, but automatic processors complete the task in 90 seconds.
time gain compensation (TGC)
in ultrasonography, electronic amplification of returning sound waves, which are weaker because they come through deeper structures, is necessary so there is an even image density through the field. This is usually represented graphically by a TGC curve on most machines.
time graph

time horizon
the period until which the economic analysis under consideration applies.
time series
a distribution of data according to occurrence.
time-space series
a distribution of data according to the time and the place of occurrence.
time value

Patient discussion about time

Q. what are the chances for a one time epileptic seizure? I had an epileptic seizure a few years ago and after all the tests it appeared to be a one time seizure. I know having one indicates my tendency for this kind of seizures so should I be afraid now to do things that might bring it up again- like alcohol, drugs, being exposed to flashing lights or having lack of sleep? what are the chances of it to come back after 5 years? any help will be very appreciated....thanks!

A. After 5 years with no recurrence of seizures after a one time episode, tha chances of having another one are low, almost exact to the general population. I would not advise you to start heavily drinking alcohol and doing drugs, because these things can certainly have an effect, however you need not be afraid.

Q. i get headaces all the time what do i need to do?

A. Is this new? Are these headaches worsened after lying down? What side of the body are they?

Constant headache in young female may be migraine or pseudotumor cerebri, both have treatments that necessitate prescription by a doctor.

Q. my legs hurt all the time, what is wrong with them? they ach in the joints and sometimes I get burning needle point pain and the muscles feel like sandpaper

A. There can be a lot of reasons for leg or joint pain, and usually there are not specific problems you can deal with medically. Are you exercising too much? Sometimes stress fractures from running can cause the kind of pain you are describing. Either way you should see someone about this if it is bothering you, either an orthopedic surgeon or a neurologist.

But even if- imagining a man quite exempt from all influences, examining only his momentary action in the present, unevoked by any cause- we were to admit so infinitely small a remainder of inevitability as equaled zero, we should even then not have arrived at the conception of complete freedom in man, for a being uninfluenced by the external world, standing outside of time and independent of cause, is no longer a man.
