Pulmonary Artery Catheterization
Pulmonary Artery Catheterization samer kareem 1,650 Views • 3 years ago

Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.

Chicken Pox
Chicken Pox samer kareem 1,648 Views • 3 years ago

Chickenpox (varicella) is a viral infection that causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who haven't had the disease or been vaccinated against it. Before routine chickenpox vaccination, virtually all people had been infected by the time they reached adulthood, sometimes with serious complications. Today, the number of cases and hospitalizations is down dramatically. For most people, chickenpox is a mild disease. Still, it's better to get vaccinated. The chickenpox vaccine is a safe, effective way to prevent chickenpox and its possible complications.

Deviated nasal septum
Deviated nasal septum samer kareem 1,647 Views • 3 years ago

A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is displaced — or deviated — making one nasal passage smaller. When a deviated septum is severe, it can block one side of your nose and reduce airflow, causing difficulty breathing. The additional exposure of a deviated septum to the drying effect of airflow through the nose may sometimes contribute to crusting or bleeding in certain individuals. Nasal obstruction can occur from a deviated nasal septum, from swelling of the tissues lining the nose, or from both. Treatment of nasal obstruction may include medications to reduce the swelling or nasal dilators that help open the nasal passages. To correct a deviated septum, surgery is necessary.

Blood Transfusion
Blood Transfusion samer kareem 1,642 Views • 3 years ago

A blood transfusion is a routine medical procedure that can be lifesaving. During a blood transfusion, donated blood is added to your own blood. A blood transfusion may also be done to supplement various components of your blood with donated blood products. In some cases, a blood transfusion is done with blood that you've donated ahead of time before you undergo elective surgery. During a typical blood transfusion, certain parts of blood are delivered through an intravenous (IV) line that's placed in one of the veins in your arm. A blood transfusion usually takes one to four hours, though in an emergency it can be done much faster.

Reactive Arthritis Causes
Reactive Arthritis Causes samer kareem 1,641 Views • 3 years ago

Reactive arthritis is a painful form of inflammatory arthritis (joint disease due to inflammation). It occurs in reaction to an infection by certain bacteria. Most often, these bacteria are in the genitals (Chlamydia trachomatis) or the bowel (Campylobacter, Salmonella, Shigella and Yersinia). Chlamydia most often transmits by sex. It often has no symptoms, but can cause a pus-like or watery discharge from the genitals. The bowel bacteria can cause diarrhea. If you develop arthritis within one month of diarrhea or a genital infection – especially with a discharge – see a health care provider. You may have reactive arthritis. - See more at: https://www.rheumatology.org/i-am-a/patient-caregiver/diseases-conditions/reactive-arthritis#sthash.PukaaQhj.dpuf

http://how-to-get-pregnant.info-pro.co ----- How To Get Pregnant, Ways To Get Pregnant, Best Days To Get Pregnant, Easiest Way To Get Pregnant. Signs of Infertility. What exactly is infertility? The problems with either conceiving a child, or with carrying out the pregnancy to its eventual fruitful end, fall under the definition of infertility. Infertility is the incapability of an individual to become pregnant, in case of females, or the incapability to induce pregnancy, in case of the males. The inability of an individual to carry out a pregnancy to its full term is also dubbed infertility. How does one recognize infertility? What are the signs of infertility? Signs of infertility are not always evident. Most people go through life without knowing there is a problem with their reproductive systems, attributing failed pregnancies to providence. In fact, miscarriages are the most common indicator of infertility. Signs of infertility in women: In women, the signs of infertility are more readily recognized as compared to men. Endometriosis causes the lining of the uterus to grow outside the uterus. Bacterial infections may begin around the uterus and spread to other reproductive organs, resulting in infertility. Fibroids in the uterus are indicative of infertility. Tumors in the cervix often cause stenosis, or narrowing of the cervix, which is a common indicator of infertility. Ovulating before the tenth day and after the twentieth day of one's monthly cycle, pre-menstrual spotting, menopausal symptoms, etc. are indicative of luteal phase defect, and thus in turn are signs too.

Ischemic Colitis
Ischemic Colitis samer kareem 1,637 Views • 3 years ago

Ischemic colitis occurs when blood flow to part of the large intestine (colon) is reduced, usually due to narrowed or blocked blood vessels (arteries). The diminished blood flow doesn't provide enough oxygen for the cells in your digestive system. Ischemic colitis can cause pain and may damage your colon. Any part of the colon can be affected, but ischemic colitis usually causes pain on the left side of the belly area (abdomen). The condition can be misdiagnosed because it can easily be confused with other digestive problems. Ischemic colitis may heal on its own. But you may need medication to treat ischemic colitis or prevent infection, or you may need surgery if your colon has been damaged.
