The Aqua-Lung

Fleuss, adds to the first workable, independent diving ring that used compacted oxygen. In this model of shut circuit scuba, which is the precursor of present day shut circuit scuba units utilized by military jumpers, carbon dioxide is consumed by rope absorbed scathing potash, so that breathed out air can be re-inhaled . Despite the fact that profundities are constrained, the contraption takes into consideration moderately long base times, up to three hours. In 1880 Fleuss' contraption is utilized by the popular English jumper Alexander Lambert to enter an overwhelmed passage and seal a portal entryway; the portal is 60 ft down and 1000 ft once more into the

This experiment was conducted to show the importance of a surfactant using common household items and demonstrating how surface tension works in the respiratory system. Surface tension, according to Marieb and Hoehn, is when water molecules in the alveoli lining are attracted to each other and draw each other to a smaller dimension (Marieb & Hoehn, pg. 715). This means that this type of attraction can pull the lungs inward and cause them to collapse due to the attraction of molecules, but other opposing forces prevent them from staying that way, such as the lung’s ability to produce a fluid that reduces

Good morning everyone! Signing on, India Hornsby with ASAP Health. I will be reporting live inside Mrs. Frizzle. She has been under the weather for about two days now. A bacterium is invading the lower lobe of her right lung. It’s my job to pilot the invasion and do a live report on what I see. I will enter from the right femoral vein and follow a path to the lower lobe of the right lung via the right pulmonary artery. I will be describing the structures that I pass by and through. Once I have reached the lung, I will describe the structures that I see and discuss how the body fights against

The water in the walls of the alveoli help the alveolar walls come together during exhalation (when the oxygen leaves the alveoli), so that they stick together and allow the alveoli to reach their smallest size. The surfactant that is secreted aids the walls to be able to come together, but not with the attraction of their potential because it’s too strong. If they came together with their normal attraction, the walls would stick together and their strong surface tension would not allow them to unstick. A collapsed alveola will have to be completely re-inflated during each inspiration, which takes a lot of energy to do. With the surfactant, during inhalation the incoming gas is able to split the walls open because their attraction is not as strong. This way, the walls are able to come apart easier and make more space for the oxygen that fills up the alveoli. If our alveolar cells did not produce surfactant whatsoever, breathing would be very hard. Each inhalation would not have the easy flow it has now; it would take a lot of energy and not to mention be tougher.

Oxygen breathing lungs are a universal trait of class reptilia. As such, it would have been necessary

The inflatable vest releases rapid burst of air onto the chest cavity and helps loosen the mucus in the lungs. The inflatable vest is extremely effective at breaking up the mucus and allowing the user to breathe with ease. The inflatable vest has two parts a vest and an automatic air pump. When the vest inflates the rapid burst of air cause the body to vibrate and it helps loosen the mucus inside of the user. The only side effect of the vest is that after the mucus has been loosened the user’s body will involuntary cough in an attempt to clear out the newly loosened mucus. The inflatable vest can be used without assistance from any other person and will not have any effect on a treatment currently going on as

How is it possible for scuba divers to stay underwater for a long period of time? A man named Jacques Cousteau made that all possible. His invention of the aqualung made scuba diving possible, letting people explore the underwater world.

Managing complex ventilator patients require critical thinking to solve problems pertaining to ventilator issues. Even though I am a certified ventilator paramedic, ventilator management is managed an respiratory therapist. Having the ventilator certification was useful in which I was able to apply my knowledge to

Who created the tank-Lancelot Eldin "Lance" de Mole, (13 March 1880 – 6 May 1950) was an Australian engineer and inventor. He made several approaches

Jules Verne, otherwise called the father of sci-fi, was a wellspring of inspiration for innovators who needed to look for accomplishment in submerged innovation. Verne presents the Nautilus, which is an effective submarine that Captain Nemo imagined himself. Nemo plot the power and quality of his imagined innovation, expressing "Yes, keen, nervy, and immune! It fears neither the unnerving tempests of the Red Sea, nor its streams, nor its reefs" (Verne 212). This innovation caught individuals' consideration. Amid this day and age in France, numerous neighborhood innovators were additionally working out the complexities of building submarines. In 1863, a couple of years before Verne composed his novel, Le Plongeur, a 140-foot submarine, was finished. This ship was worked to convey twelve men however had issues with weight and remaining above water. Despite the fact that this submarine was not fruitful, hardware and submerged innovation kept on winding up noticeably more progressed. The scuba outfit was created by Frenchmen Benoit Rouquayrot and Auguste Denayrouze in the 1860's. Their set is provided with air pumped from the surface into a shut protective cap suit; the suit is additionally fitted with a supply so that the jumper could segregate himself from the air hose for a couple of minutes. Nemo's dominance of science and designing was shown by his plunging suits and power firearms. In

Jacques Cousteau played an important role in oceanography, he was a French naval officer, explorer, scientist he https://ed.ted.com/on/aFghd4xe and studied the sea and all forms of life in water. One thing he did was co-develop "Aqua Lung". In 1943 the first aqua lung prototypes came about. These prototypes made in Boulogne-Billancourt by the Air liquide company this breathing device is known today for scuba diving.

(#5) This is a benefit to society because it is so light whereas scuba diving equipment is hundreds of pounds.

The idea using the power of steam to our advantage goes back nearly twenty-one centuries. A learned writer in ancient Alexandria, named Hero, wrote a manuscript describing various devices and ideas of the time. Although it is not proven that Hero was the inventor of any of these devices, he is given credit for the earliest mention of steam power. Hero describes a method to open the doors of a temple with the action of a fire on the alter at the front of the temple. A series of pipes runs between the alter and the temple doors. The force of the steam created by the fire on the alter is strong enough to open the temple doors. The essential principle that Hero used was to change heat energy into mechanical energy or work. Supposedly, Hero continued his work and ended up creating what is often called the "First Steam Engine." Hero's engine is featured on below on the right. The cauldron or bowl like portion AB holds water. There is a steam tight cover place over top of the cauldron. Two pipes extend from the lid and suspend a globe directly above the cauldron. The water is heated, causing steam to be created and forced through the pipes. The globe then fills with steam. Pipes K and H are located on opposite sides of the globe and allow the steam to escape when the pressure becomes uneven. The escaping steam then causes the globe to spin on its axis.

    In 1601, Giovanni Battista della Porta described a machine that could be used to raise a column of water with the use of steam.  He described this machine in a work entitled "Spiritali."  Porta's work included a vacuum created by the condensation of steam into which water would flow.  Porta's apparatus, was called the "Pneumatica."  Porta's machine was described as being able to raise water with steam pressure.  Although Porta's machine was never applied to any practical uses, he accurately described the necessary presence of a vacuum created by steam to raise the water.

"I fell in love with the way you fall asleep: slowly, and then all at once.", "I fell in love with the way you touched without using your hands."; these were just some of the quotes that I read, and connected when I thought about him. I didn't want to admit it, I waved it all off as a crush, puppy love, and it's just teenage hormones. The reality was I was falling for him with every passing moment. This feeling is so peculiar; it stretches throughout my whole body. It's inundating, yet makes me feel complete. It feels as though I'm in a dangerous fire, yet I'm completely safe at the same time. It feels as though someone's given me tranquility. It feels as though my heart is dancing around my chest; and a hole, I never knew was there, has been filled. I feel so light like I'm on top of the world yet my heart is constricting and it feels as if there's no oxygen in my lungs. When we made eye contact in the halls it seemed as if everyone else stopped and for a few moments in time it was just us. If only that were true.
