Introduction

The respiratory system allows you to obtain oxygen, eliminate carbon dioxide, and regulate the blood’s pH level. The process of taking in air is known as inspiration, while the process of blowing out air is called expiration. A respiratory cycle consists of one inspiration and one expiration. To accomplish this major function known as respiration, these four processes (pulmonary ventilation, external respiration, transport of respiratory gases and internal respiration) must happen. During pulmonary ventilation best known as breathing, air is moved into and out of the lungs (during inspiration and expiration) so that gases are continuously changed and refreshed. Oxygen diffuses from lungs to the blood, and carbon dioxide diffuses

A respiration belt will be strapped around the test subject and connected to a computer-interfaced Gas Pressure Sensor. Each respiratory cycle will be recorded by the computer, allowing you to calculate a respiratory rate for comparison at different conditions. These are the objectives of the experiment. In addition to monitoring the conditions of the respiratory patterns; evaluate the effect of holding breath on the respiratory cycle and the also evaluate the effect of rebreathing of air on the respiratory cycle. Our hypothesis is that the respiratory rate will differ from one another; more specifically the respiratory rate will decrease during the holding of breath and will quickly increase once the inspirations and expirations return. We suspect the rate will also spike and increase drastically during the rebreathing of air on the respiratory …show more content…
The pressure did not increase. In fact, throughout rebreathing of air the recorded kpa ranged from 117.65kPa (0-30 seconds) to 115.83kPa (120-150 seconds) to 115.44kPa (240-270 seconds) it decreased by two. With the results received it is implied that the respiration rates will be different and that there are several factors that contribute to the evaluation of controlling the human respiration. Perhaps our test subject is more relaxed than others and is conscious of their breathing therefore allowing more control of their breaths in

    The materials and apparatus used in this experiment were: a PC computer, IWX/214, LabScribe Software, SP-304 Spirometer, FH-300 Spirometer flow hear and plastic tubes. The regular set up of the apparatus and more details of the procedure can be found from the Lab Manual on laboratory # 10 respiration, which was used as a reference. After setting the computer software (LabScribe), and calibrating voltage to 22 L which was written in the spirometer black box, a test of the Spirometer was performed to make sure it was in the right position. (A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs.) It was tested by recording one person breath on the software and observed the waves in the lung volume screen.…

    When the bronchioles are relaxed it causes the bronchiolar lumen to increase, thereby increasing the flow of air. The bronchioles regulate the flow of air to the alveoli, alveoli are the tiny air sacs that form at the end of the bronchioles that are encompassed by tiny capillaries. This is where the gas exchange takes place. Oxygen then passes through the alveoli and travels through the capillary walls and into the bloodstream. Simultaneously carbon dioxide transfers from the bloodstream into the alveoli, then gets…

    Mammals inhale oxygen though their mouth as part of ventilation and exhales carbon dioxide. The air travels down the trachea before it branches off into the two bronchi. Branching off the bronchi are the bronchioles that transport the air to the alveoli where gas exchange takes place. The alveoli are air sacs.…

    As vasoconstriction increases due to increased pulmonary vascular resistance hypoxia occurs and eventually respiratory acidosis and is monitored through arterial blood gases (Kuhajda et al., 2014). Upon examination patient appears to be in respiratory distress - gasping for air and tracheal deviation as the lung space has decreased and pressures continue to rise, neck vein distention due to altered cardiac output, cyanosis and agitation set in as time goes on due to hypoxia and the increasing difficulty to breath (Crimlisk, 2010). Palpation reveals subcutaneous emphysema as air is trapped within the tissues. Upon listening to the patients chest there is reduced air entry and percussion reveals hyperresonance (Kuhajda et al., 2014). Generally, air enters the pleural space which shifts the equilibrium causing pressure on the surrounding organs and decreases adequate perfusion and…

    Introduction The purpose of the lab was to see the effects of heart rate and blood pressure when 3 male and 3 female students exercised compared to when they were at rest. My hypothesis is that the data from the exercise part of the experiment will cause both the heart rate and blood pressure (systolic and diastolic) to increase more than the resting state.…

    The first trial conducted started at only three miles per hour. Not much work was implied on the body therefore not increasing the heart rate and breathing rate much. For the second trial, the speed was increased by two miles to five miles per hour. A bit more of force was used, putting the body to work a bit harder. Since the body was working harder, the heart rate, along with the breathing rate, increased.…

    The subjects walked 1609 meters as fast as they could without them actually trying to run it or trot it. The prediction of maximum oxygen consumption, or V02 max, was performed during the one mile walk test. The actual evaluation was performed on a running track. Each one hundred meters of the track was marked for heart rate collection. The machine used to evaluate the subjects heart rate was done by the means of a Polar heart rate monitor and the RPE was done for each participant being…

    All three subjects paused at the end of expiration. The pause is caused when the pressure in the lungs is equal to the atmospheric pressure. Inspiration starts when chemoreceptors sense there is a high amount of CO2 in the blood, which then tells the body to contract the diaphragm and external intercostal muscles to contract, which increases the volume of the thoracic cavity. Due to this increase in volume of the thoracic cavity, and decrease in pressure, the air will wants to move to an area where there is less pressure, which is inside your…

    Sometimes the respirations are counted when the pulse is taken, so the patient cannot alter their breathing. To take respirations, have the patient sit straight up or just relax. Place a hand on the wrist just like for a pulse. For one minute, using a watch with a second hand, count the respirations. As the chest rises once and falls once that is one breath (respiration).…
