Introduction
Carbon monoxide (CO) is a tasteless, odorless, and colorless toxic gas that is produced primarily as a result of incomplete combustion of carbon material. Due to humans inability to perceive this gas CO it is commonly referred to as ‘silent killer.’ Inhalation of CO is the leading cause of accidental deaths in the United States. Excluding deaths caused by fires, there are around 2,700 deaths as a result of carbon monoxide poisoning annually. The Center for Disease Control and Prevention (CDC) reports that around 450 deaths are caused by accidental CO toxicity every year. While the total number of deaths seems low, an estimated 50,000 people in America visit the emergency hospital departments showing signs of CO poisoning. Exposure to CO results

It causes death by the CO binding rapidly to the haemoglobin (Hb) resulting in the carboxyhemoglobin (COHb) formation. As a result, the blood’s oxygen carrying capacity is reduced leading to tissue hypoxia (Chand-Meena, 2014). The presence of COHb changes the Hb’s oxygen affinity by altering oxyhemoglobin dissociation reducing the oxygen delivered to the tissues, leading to tissue hypoxia. More importantly, other oxygen-carrying hemeproteins such as cytochrome P-450, myoglobin, and cytochrome c oxidase also compete with oxygen for binding sites (Caughey, 1970). It has been demonstrated that cytochrome oxidase oxygen affinity causes impairment of mitochondrial respiration. Even though the level of COHb is a vital clinical measure of carbon monoxide exposure, the most crucial mechanism by which carbon monoxide causes toxicity is its combination with cytochrome oxidase. In addition, carbon monoxide may produce toxicity by binding to myoglobin causing impairment of the cardiac output and leading to cerebral ischemia. The dissociation of carboxymyoglobin is slower compared to COHb because of CO’s increased affinity for myoglobin (Myers, Linberg, & Cowley,
Because the PCO2 levels are too high the body is not getting the adequate amount of oxygen. This means the oxygen-carrying hemoglobin is not working properly do to the excessive amounts carbon dioxide causing respiratory acidosis.
Carbon monoxide is a potentially deadly gas emitted by gas burning appliances. Considering it is colorless, odorless and tasteless if a leak occurs only a carbon monoxide detector can alert you and your family to its presence in your home. Install the detectors near the bedrooms and at least one on each floor.

The book The Expressiveness of the Body and the Divergence of Greek and Chinese Medicine by Shigehisa Kuriyama overall felt like it was about perceptions of ancient medicine between the east and west. The author goes back and forth comparing and contrasting the different approaches of the Greek and Chinese, where even though both cultures have different approaches there actually are some similarities, which was believed due to, “the movements of people” (page 204). The book is separated into three parts: styles of touching, styles of seeing and styles of being.
a. P) Carbon monoxide molecules happen to be just the right size and shape, and happen to have just the right chemical properties, to fit neatly into cavities within hemoglobin molecules in blood that are normally reserved for oxygen molecules.
The following quote supports this theme because the discovery of that carbon monoxide cannot be absorbed by a body after death led to innovations in forensic science in the courtroom. Ever since forensic sciences had started, they were not really taken seriously as evidence in the courtroom. Often forensic toxicologists were forced to prove themselves to jurors by poisoning cats or swaying flasks of chloroform in front of them to prove their work. Now, they would be taken seriously with a testimony and statistics. Through experiments with deceased people and carbon monoxide Gettler proved that “soaking in carbon monoxide for hours after death had no effect at all…without breath, carbon monoxide was just another gas aimlessly swirling in the air” (144). This connects to biology because you need to be able to inhale carbon monoxide for it to have an effect on you. Once breathed in, carbon monoxide bonds to the transport protein hemoglobin, muscling oxygen out of its path. The result is carboxyhemoglobin, which is transported to your cells through the bloodstream. You soon die because your cells are staved of
The Bodies Exhibition at the South Street Seaport in New York City is one of several exhibitions of its kind around the world that was first displayed on August 20, 2005 in Tampa, Florida. Similar exhibitions are showing in Vienna, Madrid, Buenos Aires, Barcelona, Cincinnati, Santiago, Prague, Branson, Pittsburgh, San Diego, Las Vegas, Fort Lauderdale, Hartford, and Washington D.C. The exhibit is unique, consisting of real human bodies in various forms of disembowelment. Each body system was addressed in its own individual exhibit, starting with the skeletal system and progressing through the muscular, nervous, circulatory, digestive, respiratory, urinary, and reproductive systems plus an exhibit on fetal development. Healthy and diseased
Upon reading, I noticed the thesis had 2 arguments even though and I understood that this essay pertained to how social media caused body image issues for teens. One of the topics consisted of how social media causes teens to have "excessive concern[s] on looking perfect," and another subject matter on how phones allowed for photographs to occur anywhere. Therefore, I find it unnecessary to include the phrase - "with their phones it is easier to to take pictures everywhere." Aside from that and a couple grammatical errors, the thesis is well-written with a clear standpoint, which holds social media as the culprit in this
It has recently been brought to my attention that our school is looking to adopt a sustainable menu into our meal program and I would like to give my viewpoint on the matter. As one many students here at Oxford Academy this change will affect me directly. Although people may at first oppose this conversion I think if we are able to overcome the first obstacles, this change would bring a great positive impact to the environment and the health of our students.

You’ll have an unfilial son like you,” mother said. “At least I won’t saddle him with a “$6,000 debt,” Tosh said. “And I’ll send him to high school and college. You people are upside down. The parents should owe the children, not the children the parents. Look at the haoles. Obligation is to the children.
For decades, a substance known to cause burns, hospitalizations, and deaths has been found throughout the world. 3.41 million people die every year from issues related to this chemical, including over 200 children every hour. Approximately 80% of all diseases are either caused by the chemical or are somehow related to it. More substances dissolve into this substance than any other substance on earth, which is helpful for another usage of the chemical in nuclear power generators. Inhaling this substance causes suffocation, and eating too much of its solid form or drinking too much of its liquid form can cause intoxication and death. The name of this substance is Dihydrogen Monoxide, and despite its known dangers and prevalence across the United
The first phase occurs within 24 hours. It is caused by thermal damage and inflammation to the upper airway. Intubation should be considered early because of swelling and possible loss of airway. When mechanical ventilation is initiated it is important that burn victims have a higher than normal minute ventilation because they require a higher metabolic rate. The tidal volume should be at 6-8 kilograms per ideal body weight and respiratory rate should be 14 -16 breathes per minute. In the early phase, we also worry about carbon monoxide poisoning. Normal carbon monoxide levels in a healthy, non-smoking adult is usually around 5%, When CO levels are higher symptoms of headaches, dizziness, dyspnea weakness, impaired judgement, convulsions, coma, tachypnea, tachycardia, and hypotension may be present. This is caused by CO taking the site of oxygen on the red blood cell. This shifts the O2- HB curve to the left. To diagnose carbon monoxide poisoning a coximeter is needed. Treatment for CO poisoning is 100% FIO2 until CO level return to 5-10%. (There was not a carboxyhemoglobin reading for this patient all I could find was a pending reading. This would have been an easy noninvasive test that could have been perform quickly in the
to a chronic Carbon Monoxide (CO) poisoning at lower concentrations from airplane’s fuel emissions. The amount of CO she inhaled on a daily basis was equivalent of smoking 100-800 cigarettes. Plaintiff suffered from migraine-like headaches, chest pain, blurring of vision and irregular heartbeat, she was tired and disoriented all the time. All symptoms indicate that CO presence in her blood was close to 50% and very close to a deadly level (Exhibit 2)
Throughout today’s society, media contributes to almost everyone’s daily life. From informative news channels to comical television shows, media proves to be effective in advertisement, releasing messages and informing the audience. Although media proves to be wildly effective in advertising, releasing messages and informing the audience, periodically destructive and misleading messages are provided to the audience and directly influencing women. Cultural critics widely agree that media tends to negatively influence women and all the critics point to research which supports the belief that women are portrayed as subordinate to men, having no
