Lung capacity is the total amount of air that a person’s lungs can hold. Lung capacity can be increased through aerobic exercises, resulting in a larger lung capacity to provide better oxygen transport throughout the body (2). Only one-third of lung capacity is used for normal activity, but is increased and requires more oxygen when undergoing strenuous activities. Lungs are apart of the respiratory system and help assist in breathing, so when air is inhaled, the lungs push out oxygen to the blood where it is then carried to each cell. Lung capacity varies from female to male and from athlete to singer. It has been proven that males have a larger lung capacity than females, and taller people usually have a larger lung capacity
1. Dependent Variable. respiratory volumes 2. Independent Variable. level of physical activity [resting or exercising] 3. Controlled Variables. height; age; sex 4. Which respiratory volume was calculated? Breating rate, TV, ERV, and IRV. 5. What was the purpose of the nose clip? the nose clip was used for the lung function testing to prevent leakage with
TABLE 1: This table represents the lung capacity of people who do exercise constantly, 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.
Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
The objective of this study was to determine the acute and immediate effects of cold and warm air exercise on pulmonary functioning testing (PFT) and the presence of exercise-induced bronchospasm (EIB) in seemingly healthy athletes. The researchers also wanted to conclude if there was a significant decrease of PFT variables like peak expiratory flow rate (PEFR), forced vital capacity (FVC), and forced expiratory volume in one second (FEV1.0). The study included the participation of eight men and four women with a mean age of 31.6 + 4.8 years and 27.3 + 5.0 years respectively. Each runner had to confirm the following prior to participating in the experiment: 1) rid of any metabolic, cardiac, and respiratory diseases, 2) run at least 20 miles each week, and 3) land within 21 and 45 years old. The experiment occurred in January in Minnesota. The two settings were an outside course and a treadmill indoors with a 6% grade and speed adapted to accommodate the runners’ 85-95% maximal heart rate (MHR).
An incentive spirometer is a device that our patients use to improve the function of their lungs. This main underlying principle is that breathing can be exercised to train the expansion of lungs capacity (Potter, Perry, Stockert, & Hall, 2013). Patients who qualify for this intervention include those who have recently had a surgery, were under anesthesia, or have been placed on bed rest. Our main concern here is that these situations create opportunity for less activity within the lungs, which can put the patient at risk for pneumonia.
Spirometry is basically an instrument to measure the air capacity of your lungs. People take a spirometer to check their lungs. A pulmonary function
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.,
Spirometers are used in the medical field for detecting and grading the severity of respiratory related disorders. Spirometry is often used in medical settings like hospitals and clinics. They measure airflow and lung volumes to detect for any abnormalities. A specific example would be testing for diseases like asthma, emphysema, and chronic bronchitis. People with asthma have inflammation of the lungs causing bronchi muscle spasms. This ultimately constricts the airways and reduces air flow. A spirometer would display this information by showing lower breathing
Exercise 7: Respiratory System Mechanics: Activity 2: Comparative Spirometry Lab Report Pre-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly. 1.

You correctly answered: a. tidal volume 5. Inhaler medications for an asthma patient are designed to You correctly answered: b. dilate the patient's bronchioles.
If the spirometer includes an indicator to show your best effort, your health care provider or respiratory therapist will help you set a goal. Keep a log of your progress if directed by your health care provider.
A lung function test uses a spirometry test to measure how much air the patient can breathe in and out along with how fast they can blow air. If the results are lower than normal and the patient’s medical history reveals a pattern of asthma symptoms, the physician may then give the patient medication and repeat the test. If the results are improved with the medication, the patient most likely has asthma. To achieve more detailed information about the asthma, the physician may perform more tests to evaluate alternative diagnosis, identify the precipitating factors, assess sensitivity, and investigate potential complications. One type of test the physician may use to identify allergens that might trigger the patient’s asthma is an allergy test. A bronchioprovocation test may be performed to measure the sensitivity of the patient’s airways by using spirometry to repeatedly measure the lung function during certain triggers such as exercise or cold air. A chest x-ray or EKG may also be required to ensure there is not a foreign object or other disease causing these asthma-like symptoms (“What is Asthma” and National
According to American Association for Clinical Chemistry (AACC), Acidosis is characterized by PH of 7.35 or lower . Acidosis develops when the rate of H+ production exceeds the rate of H+ removal/buffering.
