Barotrauma

synthetic and natural surfactants have shown that synthetic surfactants with their slower response might be supported for prophylaxis use, whereas natural surfactants with their fast response might be more suitable for very sick infants at danger of barotraumas and pulmonary air leaks (Richard A et al,2014). A meta-analysis comparing the effectiveness of prophylactic vs. selective exogenous surfactant administration, carried out by Rojas-Reyes et al., 2012 showed that prophylactic administration reduces

non-existent temperature does not affect the atmosphere however provides obtainable heat energy from the sun. Outer space’s environment is also exposed to strong radiation and micrometeoroids. Conveying a human to a different atmosphere inflicts barotrauma which is the inability to equalise pressure within the body cavities. Boyle’s law explains as pressure increases on our bodies the volume of our body cavities decrease and as pressure decreases the volume is increased. A changing pressure between

Deep Ocean: The truth of the Twenty Thousand Leagues under the Sea Everyone might have once imagined dark environments and scary creatures which live in the deep sea. These childlike dreams are visualized in the popular novel, Twenty Thousand Leagues under the Sea. In the novel, the main character, Pierre Aronnax, searches for a mysterious sea monster while fighting with scary undersea creatures. Although many undersea creatures have been depicted in the novel, one of the striking deep sea creatures

Sepsis is the number one cause of death in intensive care units in the U.S. More than 750,000 cases of sepsis occur each year and about one third of those patients die from it (McKinney, 2014; Ulloa, 2011). Sepsis is a serious condition that is a result of an inflammatory response to infection that can damage organs if left untreated. Severe sepsis occurs when the infection leads to organ dysfunction. Septic shock is when multiple organ failure occurs due to infection and is worse than sepsis and

We live in a world that is frantically searching for alternative energy sources to reduce our dependence on fossil fuels and offset our negative environmental impacts. In recent years, wind production has presented a very appealing argument in favor of renewable energy. Wind energy is not associated with the typical negative environmental impacts that stem from our traditional energy sources such as air pollution, water pollution, mercury emissions, and climate change (NWCC 1). Wind power’s promise

Space Exploration: What Are the Effects of Spaceflight on the Human Body? The accomplishment of space travel on 12 April 1961 marked the dawn of a new space era. Since then, humans have advanced in technology and acquired immense knowledge through space exploration. We watch video clips of astronauts enjoying a gravity-free environment, however, there are challenges in space, the greatest threat being the lack of oxygen and pressure. Furthermore, spaceflight has a significant impact on the human

A sedated 72-year old male was admitted to the emergency department of a county hospital. The patient was complaining of chest pain and shortness of breath. This patient has a history of COPD, type-two diabetes and has quit smoking for nearly seven years. In the emergency department, the patient had labored breathing and a SpO2 of 72% on room air. This patient was then placed on BiPAP. His weight is 117kg and temperature of 99.1. Blood pressure was 61/41 on arrival to the emergency department and

The Effects of Different Ventilation Modes on Sleep Quality in Critically Ill Patients Who require Mechanical Ventilation Introduction: Sleep is a physiological process essential to the human body to rest and maintain overall health1. One complication of acute illness is sleep deprivation seen as ineffective nocturnal sleep, reduced (NREM) and (REM) sleep, and an increase in the waking hours within the circadian rhythms2. Recent studies suggest that invasive mechanical ventilation influences the

this is also another system of Environmental control system. Purpose and importance: Cabin pressurization is also an important aspect, as beyond the altitude of 3000 meters the low pressure thin air can cause diseases like altitude sickness, barotraumas, hypoxia and decompression sickness. Among them hypoxia can lead to sluggish thinking of brain followed by loss of
