Cuff Bead Bracelet
The tension or pressure (BP) is the force that blood prints driven by the heart on the artery walls and allowing the circulation throughout the arterial tree overcoming peripheral resistance. It is an indirect measurement of the degree of resistance offered by the arteries as the heart pumps blood through the body. The pressure is determined by the strength and volume of blood pumped and the size and sensitivity of the arteries. Blood pressure depends primarily on cardiac output and peripheral vascular resistance. The relationship is summarized in the following equation:. Systolic pressure: The heart contracts as it pumps the blood into the arteries. When the heart is contracting, the pressure is systolic. It is the largest. Diastolic pressure: As the heart relaxes between contractions, the pressure decreases. This is called diastolic. Is lower. Bracelet or cuff: a compression device is surrounded by a wrought iron fabric that serves to apply tension in the artery to be used. Must be tailored to patient characteristics, corresponding to a width equal to two thirds the length of the arm, and a length sufficient to cover two thirds of its circumference. Gauge: Usually mercury with a graduated scale from 0 to 300 mmHg, we can measure blood pressure values. Should always be calibrated, ie, the pointer must be set to 0 before any measurement. Rubber Roads: They can be rubber or rubber, which is responsible for guiding the air to the air pressure in the system. Bell (2): This is what is responsible for receptor function and sound transmission through the tracks. To maintain control or tracking is important that the person is taking blood pressure regularly, since a single measurement does not necessarily mean it is hypertensive or hypotensive. Hypertension: It is when the patient's blood pressure is higher than normal limits, both in relation to their age and health status. This condition increases the risk of heart failure, heart attacks (myocardial infarction), stroke and kidney failure. Hypotension: This is when the patient's blood pressure is below normal. This condition can be caused by blood volume deficit, either by extracorporeal losses, such as bleeding or diarrhea. Arm: The place of first choice. Place the cuff bead bracelet on the arm trying to make it over the brachial artery or humoral. The stethoscope is placed over the artery at the level of humoral elbow. Preferably the pressure is taken in the left arm, although this is currently not a standard. Thighs: Place the cuff bead bracelet on the thigh so that it is on the popliteal artery, the artery is located behind the knee. Is most useful when it is not possible as the brachial artery. Close the air valve and breathe rapidly until no pulse (180mmHg or more if the patient is hypertensive. , About 20 to 30 mmHg above the pressure required to note the disappearance of the pulse). Open the air valve and let the cuff bead bracelet is deflated slowly, watching the scale of the gauge and listening to the reappearance of heartbeats with a stethoscope:. We must always take into account whether the patient is familiar with the procedure, as states of anxiety or fear can vary the results. The patient may be sitting or lying, but making sure the arm is at heart level. Be sure to check that there are no obstacles (eg, clothes that fit). . . .
