Lung Capacity Lab Report

Cellular respiration is the chemical process in which organic molecules, such as sugars, are broken down in the cell to produce utilizable energy in the form of ATP. ATP is the chemical used by all of the energy-consuming metabolic activities of the cell. In order to extract energy from these organic molecules, cellular respiration involves a network of metabolic pathways dedicated to this task.

Cari’s po2 is 54 mm Hg so therefore her lungs were working as if she was doing intense exercise although she wasn’t. Decreased oxygen saturation and PO2, decrease the efficiency of gas exchange between the arterial blood and tissues of the body.

A persons lung capacity can determine someone’s exercise level because if you have a larger lung capacity it allows your body to take in more oxygen which gives your muscles more energy which means you can do exercise for a longer amount of time.

Age, height, and sex all have an effect on predicting lung volume. For flow rate, exercise is predicting factor. From the data, we see that males have higher PEFs and FVCs. This is most likely because of more muscles mass, height, and we have many male athletes. This supports the ideas that sex, increased height, and increased mass all increase the lung volumes.

The prevalence of asthma has steadily grown in both the US and world populations, and continues to do so. In the US alone, 25 million people were diagnosed with asthma by 2010 (CDC, 2013). In turn, the need to accurately assess the functionality of a patient’s lung capacity is an essential step to begin diagnosis and treatment of their condition. This paper examines the mechanical peak flow meter, which was crafted for assessing lung function capacity in asthmatic patients. In addition, comparing the advantages and disadvantages of usage of the peak flow meter, as well as the proper usage. Among the various instruments used to assess a patient’s lung capacity, the mechanical peak flow meter is the most widely used and among one of the most precise measurement tools (CDC, 2013).

Moving on to Part 2 of the respiratory lab, the experiment was designed to observe the difference between length of breath-hold and ventilation type. These ventilation types consist of normal breathing, re-breathing, and hyperventilating. The second component to part 2 was to see a correlation between the

“Asthma is an example of an obstructive lung disease in which the airways obstruct the outflow of air. In contrast, pulmonary fibrosis is an example of a restrictive lung disease in which the functional size of the lung decreases” (Michael G. Miller, John M. Weiler). Exercise-induced asthma is when the airways are narrowed in the lungs when doing the high-energy activity. In the Journal of Athlete Training, it states that at least fifteen to twenty percent of athletes show evidence of having exercise-induced asthma. Athletes that are affected by exercise-induced asthma may not able to withstand high-intensity training. If not properly treated the athlete would experience symptoms that could worsen. Exercise-induced asthma in athletes requires

There are different factors that affect lung volumes such as taller people and people who live in higher altitudes often have larger volumes compared to shorter people or people who live at lower altitudes. Other variables such as age, gender and weight also have an effect on the lung function. As a person gets older not only does the natural elasticity of the lungs

change in air temperature). In short your lungs are used more like a balloon filling up

Spirometry is the most popular lung function test. The patient performs a maximal inhalation and then forcefully exhales as quickly and as long as they are able. The spirometer measures the volume of the air exhaled by patients. These measurements are taken at two intervals. The first measurement is the forced expiratory volume in one second (FEV1), records the volume of air exhaled after one second. The second measurement is taken at the point where the patient has fully exhaled the volume of inhaled air; this measurement is the forced vital capacity (FVC) (Harpreet Ranu et al.,

Total lung capacity :Is the sum of the maximum volume to which the lungs can be expanded with the greatest possible inspiratory force. approx. 5800 ml

TABLE 2: This table represents the lung capacity of people who don’t do exercise at all, their lung capacity was measured with the balloon who after that was introduce into the bucket and water was represented en ml in the table below.

The lungs are essential respiratory organs in humans which enable us to breathe. Our lungs are specialised structures that allow us to exchange gases. We require oxygen from the air to enter our blood, as all cells need it to function. We also need to get rid of carbon dioxide which is a product of many metabolic reactions within our cells. Our lungs allow this gas exchange so we can get rid of carbon dioxide and acquire oxygen. Each person has two lungs that are connected by our trachea (windpipe). The trachea separates into two bronchi, one of each leads to a lung. These bronchi then branch off into smaller bronchioles. The bronchioles are then connected to small air

The average person’s lung capacity can be increased by 5 to 15 percent (The Effects of Exercise on Lung Capacity). Exercises, or sports that involve running, swimming, and cycling affect your lung capacity, other sports may not have the same affect (Banar, Maura). Exercise can cause your heart and breathing rates to increase, delivering fresh oxygen to the bloodstream, and more energy to the muscles (The Effects of Exercise on Lung Capacity). The most effective workout that encourages improvements in lung capacity is high-intensity aerobic training, which includes running and swimming (Banar, Maura). Lung capacity can also be increased by regular aerobic workouts, but only by a minimum amount (The Effects of Exercise on Lung Capacity). If your sport doesn't emphasize lung capacity, your muscles can still thrive, allowing you to still increase lung capacity during physical challenges (Banar, Maura). Exercising can affect your lung capacity instantly or within a few minutes (The Effects of Exercise on Lung Capacity). By exercising you are increasing and toning the heart and lungs, which is improving ranges of motion (The Effects of Exercise on Lung

Aerobic capacity is also related to an individual’s lung capacity and amount of oxygen the muscles can use (Abernethy, 2013).
