Capnography, the graphic display of the exhaled and inhaled carbon dioxide concentration plotted against time, is used to monitor ventilation. This video reviews the principles of capnography and explains how to interpret the information it provides.

INDICATIONS Administration of agents into the central vasculature Central circulation and intracardiac access Maintenance of venous access Hemodialysis and plasmapheresis

Atrial flutter is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast. When the chambers in the top of your heart (atria) beat faster than the bottom ones (ventricles), it complicates your heart rhythm

Rhinoplasty, sometimes referred to as a "nose job" or "nose reshaping" by patients, enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. What surgical rhinoplasty can treat Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide or upturned Nasal asymmetry If you desire a more symmetrical nose, keep in mind that everyone's face is asymmetric to some degree. Results may not be completely symmetric, although the goal is to create facial balance and correct proportion. Rhinoplasty to correct a deviated septum Nose surgery that's done to improve an obstructed airway requires careful evaluation of the nasal structure as it relates to airflow and breathing. Correction of a deviated septum, one of the most common causes of breathing impairment, is achieved by adjusting the nasal structure to produce better alignment.

If the artery were severed, blood would flow out unimpeded, although the artery wall would contract in an effort to stop the bleeding. After losing >30% of one's blood volume blood pressure would start dropping, and with less pressure the rate of bleeding would go down. At this stage if the blood loss wasn't replaced the person could die. Losing halve to two thirds of one's blood volume is considered to be fatal even if later on blood transfusion is attempted. One's total blood volume at 70ml/kg is estimated to be between 5 to 7 liters, so that makes a blood loss of between 2,5 to 4,7 L.

Shut the front door: Scientists have finally found the perfect breasts. No, they weren't hiding in the Amazon or roving solo across the Sahara (although we have no doubt there are women in both the Amazon and the Sahara who have magnificent mammaries); it turns out these perfect breasts were hiding in a plastic surgeon's office this whole time! Now, before you get all worked up, the American Society of Plastic Surgeons (ASPS) would like you to know that the super-fake looking plastic breasts of yore are not actually what people think are most attractive now. According to a study published in the Journal of Plastic and Reconstructive Surgery—which involved asking over 1,300 people to look at pictures of naked boobies and rank them by hotness (stop laughing, this is serious research!)—people preferred a more "real" and "normal" look from their silicone, with the ideal breast shape having a 45:55 ratio. People said the best chests have 45 percent of the fullness above the nipple line and 55 percent of the fullness below, in a slightly teardrop shape. Researchers noted this preference remained consistent across gender, racial, and ethnic groups with the 45:55 ratio favored by 87 percent of women in their 30s, 90 percent of men, and 94 percent of plastic surgeons.

Debridement is the removal of necrotic tissue, foreign debris, bacterial growth, callus, wound edge, and wound bed tissue from chronic wounds in order to stimulate the wound healing process. Stimulation of wound healing mediated by debridement is thought to occur by the conversion of a chronic non-healing wound environment to an acute healing environment through the removal of cells that are not responsive to endogenous healing stimuli. Debridement is used commonly in standard wound treatment of diabetic foot ulcers (DFUs). Methods of debridement include surgery (sharp debridement), chemical debridement (antiseptics, polysaccharide beads, pastes), autolytic (hydrogels, hydrocolloids and transparent films), biosurgery (maggots), mechanical (hydrodebridement), and biochemical debridement (enzyme preparations). Callus is a buildup of keratinized skin formed under conditions of repeated pressure or friction and may contribute to ulcer formation by creating focal areas of high plantar pressure. The debridement of callus has been proposed to be relevant for both treatment and prevention of DFU. The purpose of this report is to retrieve and review existing evidence of comparative clinical effectiveness of different methods of debridement for the treatment of DFUs. Additionally examined in this report is the clinical effectiveness for treatment and prevention of DFU using callus debridement. Cost-effectiveness, and existing debridement guidelines for the treatment of DFUs will also be reviewed.

For blunt trauma patients lying supine, drains should be placed anteriorly in the chest. This pevents a tension pneumothorax developing if the chest tube is blocked by dependent lung tissue. Normal movement of the lungs will allow drainage of a basal haemothorax through an anterior chest tube

Massive bone defects (>8 cm) will not unite without an additional intervention. They require a predictable, durable, and efficient method to regrow bone. The Ilizarov method of tension stress, or distraction osteogenesis, first involves a low-energy osteotomy1 - 5. The bone segments are then pulled apart, most often using an external device at a specific rate and rhythm (distraction phase), after which the newly formed bone (the regenerate) requires time for consolidation. The consolidation phase is variable and usually requires a substantially greater amount of time before the external device can be removed. Our technique of tibial bone transport over an intramedullary nail using cable and pulleys combines internal and external fixation, allowing the external fixator to be removed at the end of the distraction phase. This increases the efficiency of limb reconstruction and decreases the external-fixator-associated complications.

In patients with advanced congestive heart failure due to cardiomyopathy or ischemia, right ventricle shortening is the only significant independent associate of survival by multivariate analysis (as opposed to other parameters including left ventricular ejection fraction, cardiac index, and pulmonary resistance).

Beta-blockers, also known as beta antagonists, beta-adrenergic blocking agents, or beta-adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, ...Jul 27, 2015

3D scans show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension. It's natural to be really excited by the prospect of your first scan. But some mums find the standard 2D scans disappointing when all they see is a grey, blurry outline.

Open heart (coronary artery bypass, or CABG) surgery is performed in order to reroute, or "bypass," blood around blocked arteries, thereby improving the supply of oxygen-rich blood to the heart. Surgeons usually use an artery from the chest wall to construct the "detour" around the blocked part of the artery. Veins from the legs are also used.

As the liver becomes more severely damaged, more obvious and serious symptoms can develop, such as: yellowing of the skin and whites of the eyes (jaundice) swelling in the legs, ankles and feet, due to a build-up of fluid (oedema)

Kegel exercises strengthen the pelvic floor muscles, which support the uterus, bladder, small intestine and rectum. You can do Kegel exercises, also known as pelvic floor muscle training, just about anytime. Start by understanding what Kegel exercises can do for you — then follow step-by-step instructions for contracting and relaxing your pelvic floor muscles.

ACE Inhibitor Mechanisms. Angiotensin converting enzyme (ACE) inhibitors are agents used to relax blood vessels and lower blood pressure. They prevent an enzyme from producing angiotensin II, which narrows blood vessels and raises blood pressure, meaning the heart has to work harder to pump blood around the body.
