safe‚ how to live with one day-to-day‚ and how to care for a PICC line. What is a PICC Line? A PICC line stands for Peripherally Inserted Central Catheter (Treatments & Procedures‚ 2015). What this means is that a PICC line is tubing running into a vein that is in your arm. This tubing is called cannula; it is flexible‚ soft‚ small in diameter and thin. It may be uncomfortable when first inserted‚ but once it is in place‚ it should not be painful. That patient will just have to be careful with it

by the force of the blood following up on the dividers of the veins or blood vessels. Two components decide the span of this power. One is the volume of blood being pumped through the vessel. The other is the extent of the vessels. Changes in blood pressure can be brought about by either an adjustment in the measure of blood being pumped or by an adjustment in the span of the blood pressure. Body mechanisms modify heart rate and vein enlargement to keep up blood pressure at proper levels. High or

Control of blood pressure The blood pressure measures the force created by the heart beat (blood) on the walls of blood vessels. The blood pressure can show an increase with age due to lack of elasticity and narrowing of arteries. The regulatory centers of cardiac and vasomotor controls the sympathetic neuron to increase the blood pressure with regard to increase in blood volume. These regulating centers are located in the medulla oblongata show vasoconstriction while increasing heart rate. When

is one of the bodies’ most vital organs‚ without it the body would not receive oxygen and could not survive. The heart is comprised of 4 chambers‚ a left and right atrium and left and right ventricle. The deoxygenated blood enters the heart via a vein into the right atrium where it moves into the right ventricle before being transported to lungs via the pulmonary artery for oxygenation before returning to the heart into the left atrium. From the left atrium the now oxygenated blood

of the umbilical arteries and‚ as follows‚ decreased venous return to the right atrium. The vascular resistance in the lungs drops and all cardiac output flows through the pulmonary vessels now. Increased return to the heart through the pulmonary veins causes the raised pressure in the left atrium. As result of the changes described above foramen ovale is closed because the pressure in the left atrium becomes higher than in the right atrium. So‚ the blood cannot move from the right atrium to the

frequently can be useful. DO NOT use adhesive dressings‚ apply fat‚ ointment or lotions‚ break a blister or touch a burn. NOSEBLEEDS To take care of a nosebleed Sit upright and lean forward. By remaining upright‚ you reduce blood pressure in the veins of your nose. This discourages further bleeding. Sitting forward will help you avoid swallowing blood‚ which can irritate your stomach. Pinch your nose. Use your thumb and index finger to pinch your nostrils shut. Breathe through your mouth. Continue

our lungs. The heart rate is measured in beats/ minute and a “beat” is when the lower chambers are (two ventricles) contract. This process pushes the blood into high pressure arteries to the low pressure veins. Heart rate is most easily measured by counting the pulse of the blood in artery vein in your neck. Motivation/Purpose: It is good to measure heart rate constantly. People are constantly developing heart conditions that aren’t known until it’s too late. Asthma is constantly being developed

areas such as your brain. Veins must work hard to get blood back to your heart. As a person reclines‚ the heart does not have to pump as hard to reach the same areas‚ decreasing the blood pressure. Also‚ a person is usually more relaxed in a reclining position‚ which slows breathing and heart rate. Less oxygen is needed to support the body. It differs because your heart has to work harder when standing. the blood that reaches your legs has to travel back up through veins in your legs as gravity
