High Level Design:
A catheter based device to detect the abnormal/diseased atrial tissue substrate. This substrate is usually responsible for maintaining and initiation of atrial fibrillation. The device can comprise of an elongated tube to be placed inside the atria with a detector for detecting the disrupted electrical impulses. This detector could be a sensing electrode with a transducer as a sensor which converts the activity of the tissue substrate into an electric potential which can be easily detected by the ECG. Apart from this there is also the requirement of a signal processor that processes the acquired electrophysiological signal data to identify location of the diseased tissue sites that are responsible for

An additional contrast feature to assess fibrosis which is a substrate for arrhythmias can be added. The depth of the lesions can be obtained by collecting diffusely scattered light. Substrate maps can be used to correlate images with the 3D voltage maps. Tracking dynamics can be used to identify pools of blood with the help of a catheter over it to target lesions. A catheter with OCT can be used to get visual spectra and to deliver energy for the burning of tissue once identified correctly.
Major Scientific and Technological Risks:
Scientific risks:
• As with any catheter based device there are the usual risks of infection at the insertion site. Sometimes even bleeding and pain can occur.
• There are chances that the catheter might damage the blood vessels by poking or scraping them.
• It might be problematic for the detector/sensor to be placed at one point and might cause it to move around.
• Inadequate number of lesions poses a problem for the catheter ablation technique.
• There is inadequate understanding of atrial fibrillation causes and treatment which poses a problem to find a cure for it.
• Because this a detection device there are chances of false-positive or false-negative results which needs to be double checked before proceeding with either treatment or non-treatment.
Technological risks:
• Cost: The cost of this device can range from economical to
It can also occur during blood transfusion or during dressing change. The insertion of central catheters can occur in the Interventional Radiology or sometimes at the bedside. Regardless of the where the insertion process occur, a sterile field must always be maintained and sterile techniques must always be employed to prevent any organisms from being introduced to the central line into the patient. According to The Joint Commission (2013), many organizations such as Michigan Keystone Intensive Care Unit Project and Institute for Healthcare Improvement are actually adhering to insertion bundles to reduce the CLABSI rates. The bundles include hand hygiene, maximal barrier precautions, chlorhexidine skin preparation, avoidance of femoral vein, and prompt removal of central catheter. Furuya et al. (2011) studied the effectiveness of the insertion bundle and how it impacts the bloodstream infections for patients in the Intensive Care Unit. As a result, lesser infection have occurred when the compliance is high. As mentioned, the site of the catheter also needs to be considered in the insertion process. Avoiding areas such as the groin to access the femoral artery is recommended because this area can be easily contaminated with urine or feces. In addition, after the insertion of a new central line, all the used IV tubing
4) Significance: This research shows that there is a gap in the evidence, but that the primary concern for nursing staff is to ensure that catheters are removed as soon as it is possible to do so.
Only when it is absolutely necessary should a catheter be inserted into a patient. Every patient is assessed for the need for a Foley catheter. If the Foley is inserted, assessments are also then done daily to see if the need is still valid. If the reason is not justifiable the catheter must be removed from the patient (Joint Commission releases new NPSG for CAUTI, 2011). Nurses must follow guidelines while inserting indwelling catheters as well. Aseptic technique is critical to maintain during this process. The use of sterile equipment and a sterile procedure helps to reduce the risk of CAUTI. If in any way the catheter becomes contaminated during the process of insertion, the nurse should discard of the entire catheter and start with a new, sterile kit. Proper hand hygiene is very important before and after contact with indwelling catheters to decrease risk of infection. Maintenance of a close drainage is system is also important that way bacteria are not able to get in and cause infection (Revello & Gallo, 2013). Decreasing the number of times Foleys are inserted and how long they stay in for can help reduce the risk of CAUTI since the longer a Foley stays in, the higher the risk of infection becomes. Nurses must keep the catheter line patent, with no kinks to allow urine to flow freely through into the collection bag. When a urine sample must be obtained it must be done in a sterile
Also another serious complication of CAUTI is BSI (Blood stream infections) that can be fatal if not caught and treated promptly. “The Clinical Performance of Quality Health Care, along with Joint Commission” offers standards and objectives for facilities to assess measure and improve their standards at the lowest cost possible. The database covers nursing care and education, along with guidelines on prevention. Moreover the JCAHO regulatory standards for catheterized patients are explained and the documentation that is expected when JCAHO inspections are rendered in a facility. The source “Stop orders to reduce inappropriate urinary catheterization in hospitalized patients” states that by following standard precautions with every patient these infections can be prevented. . Also the source explored whether catheters should be used at all in an effort to decrease the incidence of CAUTI’s. Intermittent catheterizations along with supra-pubic were explored with a decreased incidence of bacteria being present in the bladder afterwards. The source “Strategies to prevent catheter-associated urinary tract infections in acute care hospitals” offered ways of cleansing and disinfecting the skin before insertion to reduce the risk of infection. Many CAUTI’s are linked to bacteria harboring in or around the site at insertion. By using not only aseptic technique but also cleansing the skin with chlorhexadine can decrease he incidence of infection
According to a study conducted in 2011 by the government, approximately 80% of urinary tract infections associated with indwelling catheters, increase the hospital length of stay by one to three days, and according to the Centers for Medicare & Medicaid Services (CMS), have an annual cost of
Getting an infection from improper care during or after insertion of a central line is the last thing you want to get while in the hospital. This paper will discuss Kaiser Permanente’s policy on central venous catheter, also known as a central line, care and dressing change, and whether it follows the current evidence-based practice on preventing bloodstream infection in patients who have them inserted. I will explain about what a central line is, why evidence-based practice is important in the clinical setting, what Kaiser Permanente’s policy about central line care and dressing change is, if Kaiser is currently following evidence-based practice based on current articles about preventing central line associated bloodstream infections (CLABSIs), and what my role in using evidence-based practice is as a future registered nurse.
Most physicians and people who acquired the problem usually know it as A-FIB, a shorter term for atrial fibrillation. Atrial fibrillation deals with the cardiovascular system, in particular, the heart in the body. It is defined as, “the electrical signals that control this system are off-kilter. Instead of working together the atria do their own thing, causing fast fluttering heartbeat, also known as arrhythmia” (WEBMD). In a normal pumping blood of the heart the atria would squeeze first, followed by the ventricles of the heart. A-fib can be a serious issue if not treated, due to the inadequate pumping of the blood, causing a higher chance of heart failure. It is also a higher chance in getting a stroke, because improper flow of the blood can cause clots in the
Until recently it was not uncommon for patients admitted to an acute care facility to have an indwelling catheter anchored for unnecessary reasons. Patients that came in thru the emergency department typically were sent to the units with unnecessary indwelling catheters in place and it was not unusual for a surgery patient to have an indwelling catheter anchored before or during a procedure. Once a patient was admitted and was transported to the units nursing would also anchor indwelling catheters for multiple unnecessary reasons. These Catheters could be
Furthermore, the other important pathogenic determinants of CLABSI are the material of which the device is made, the host factors consisting of protein adhesions such as fibrin and fibronectin which form a sheath around the catheter and the intrinsic virulence factors of the infecting organism, including the extracellular polymeric substance (EPS) produced by the adherent organisms. Catheters made of surface irregularities materials are especially vulnerable to microbial colonization and subsequent infection. This association has led to emphasis on preventing catheter-related thrombus as an additional mechanism for reducing CLABSIs.

A coronary angiography provides information about the hearts blood pressure and functioning. This procedure can identify whether the coronary arteries are blocked or narrowing. A tube/camera is passed through an artery in the groin or arm; it is guided using x-rays up to the heart. A coronary angiogram is a safe procedure, but there are some small side affect. You may feel a slightly strange sensation when the dye is put down the catheter, a small amount of bleeding when the catheter is removed, a bruise in your groin or arm.
Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal strip, one can clearly identify a P wave before every QRS complex, which is then followed by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P
Do not pull on the midline catheter or tubing. This can dislodge the midline catheter from the vein. If the midline catheter is dislodged, the IV fluids or medication you are getting can leak into the surrounding tissue.
Today millions of Americans live or have lived with Atrial fibrillation. The main concern with this health issue is that many people who lived with it sometimes are not aware of it. Atrial fibrillation is defined by Mayo Clinic (2012) as “an irregular and often rapid heart rate that commonly causes poor blood flow to the body”. It occurs when the four chambers of the heart have a disrupted rhythm. The abnormal functionality of health may lead to a stroke because of the possible blood clot that will be formed. The Atrial fibrillation or Afib put the body in a situation without oxygen and nutrients because the body is not well supplied by a heart that is became weak. In general, only few people will feel change in their heartbeat. They may verbalize
Brusch says, “Once a indwelling catheter is placed, the daily incidence of bacteriuria can be between 3-10%.” Another large problem that results CAUTI’s is that at times, catheters are left in a patient longer than necessary. Prolonged use of
