Absoluetely yes. Have done this routinely for years. It used to be my fall-back technique, but then I elevated it to routine use. It will save you time in the long run, and is importantly particularly if the IV line needs to be left in for an length of time.
1. choose the right size cuff for the size of the limb.
2. consider inverting the cuff so the cuff tubespoint away from the puncture site.
3. take a blood pressure reading as normally done. then inflate the cuff to a level between systolic pressure and diastolic pressure. For faster results, start with initial pressure half way between the two pressures, after two minutes, decrease pressure to a level 10-20 mm above diastolic.
4. wait about 4 minutes and you will see reative hyperemia (arm starts to turn a bit red). This will be more likely to happen if the initial pressure was set higher as noted above. The hyperemia is due to the blood vessels all dilating because the blood flow was decreased to the limb.
5. during this process, keep checking the pressure on the cuff manometer since many cuffs tend to have a slow leak and need continuous pumping.
6. after 4-5 minutes, you can now palpate the limb for suitable venous candidates.
7. if only small veins are available, and if the line is not to be left in place, you can puncture the small vein in reverse.Why does this work? It works because you are not occluding the inflow to the vein while doing the puncture.

Starting with t what is the medical term for a blood pressure cuff?

no
What is the Medical term meaning blood pressure cuff?
The medical term for a blood pressure cuff is a sphygmomanometer.
What is a sphygmomanometer used for?
A sphygmomanometer is used to measure blood pressure. It consists of an inflatable cuff to restrict blood flow, a pressure gauge to measure the pressure in the cuff, and a stethoscope to detect the sounds of blood flowing through an artery.
How does the spygnomanometer work?
A sphymomanometer is used to measure blood pressure. It consists of an inflatable cuff to restrict blood flow, a pressure gauge to measure cuff pressure, and a stethoscope to listen to the blood flow sounds. By inflating the cuff and gradually releasing the pressure, the systolic and diastolic blood pressure readings can be obtained.
What is a sphygmomsnometer?
A device to check your blood pressure manually. (Blood pressure cuff)
How do you pronounce the technical name for a blood pressure cuff?
sfig-moh-mə-nom-i-tər A sphygmomanometer or blood pressure meter is a device used to measure blood pressure, composed of an inflatable cuff to restrict blood flow, and mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. They are also used in conjunction with a stethoscope to ensure accuracy.
When a blood pressure cuff is used as a tourniquet how will inflation of the of the cuff to a pressure above the patients systolic pressure affect blood flow?
Run the pressure up until the bleeding is controlled or there's no detectable pulse in the extremity distal to the cuff. -- no more. The exact number depends on the location of the wound you're trying to control and -- of course -- your patient. Note that tournuquettes are the last line of defense in controlling bleeding, and are dangerous to use in that they increase chances of sepsis and may sacrifice the limb. With arms, I think it's almost always possible to control bleeding with direct pressure.
How do you Explain the underlying cause of the Korotkoff Sounds that you detected with the Cardio Microphone as the cuff pressure was decreased?
When the blood pressure cuff is inflated, the blood flow is stopped. Slowly the cuff is decreased. When the technician starts to hear the blood flow, these are called Korotkoff Sounds. This pressure point defines the systolic pressure.
Why can you not hear a sound when the pressure of the cuff is below the diastolic blood pressure?
The pressure in the cuff drops further, the sounds change in quality, then become muted, then disappear altogether. As the pressure in the cuff drops below the diastolic blood pressure, the cuff no longer provides any restriction to blood flow allowing the blood flow to become smooth again with no turbulence and thus produce no further audible sound.
What other uses are there for a sphygmomanometer?
You can use it as a tourniquet for scientific experiments or for engorging veins for blood drawing. Also can be used in blood clotting studies where a constant pressure is required for the test to be accurate, where a small cut is made in the skin and the time taken for the blood to clot is measured.
What is the name of the device to monitor your blood pressure?
The real name for a blood pressure cuff is sphygmomanometer.
