The Values Of Inspiratory Capacity

FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is

A normal respiratory rate is between 12 & 20 breaths per minute, this can be recorded manually by using a clock. If you respiratory rate drops below the normal measurements

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

When the organs fail the only option is a transplant. With lungs there is only a 50% rate of a five year survival rate after a lung transplantation involving the end-stage respiratory disease. With such a drastic survival rate a study was completed to determine if patients could have a better outcome. This study was done to help determine effective methods to enhance lung transplants before surgery; the Doctors placed the recipients on bi-level positive airway pressure ventilation (BIPAP.) “BIPAP is a noninvasive mode of ventilation administered through a tight-fitting mask to assist spontaneously breathing patients”

The Ventilatory threshold was reached at 5 minutes or stage 3 for patient 92 C. The ventilatory threshold is important because it indicates the point at which the blood lactate acid increases non-linearly. It indicates that there is an increase in the lactate acid level in the blood as well as the excess carbon dioxide (Kenny et al., 2015). The increase in carbon dioxide will stimulate chemoreceptors to increase ventilation. The ventilatory threshold is related to the anaerobic threshold which refers to the increase in carbon dioxide and indicates that the body has shifted towards anaerobic metabolism (Kenny et al., 2015).

Use of daily spontaneous breathing trials to assess the patient’s ability to sustain ventilation, oxygenation, and breathing.

The higher her respiratory rate the more liters of oxygen needed to supply for the loss in her lungs. To get the minute ventilation you take the breaths per min times 500mL/breath and that gets your liters of oxygen per min.

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.

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.,

Necessary increase in ventilation to maintain blood gas homeostasis during exercise was compromised in some individuals resulting in a high work of breathing. When these ventilatoy demands exceed the capacity for the lung and chest wall to generate flow and volume, expiratory flow limitation can develop which may result in diaphragm fatigue. Expiratory flow limitation (EFL), is an important physiological phenomenon since it is associated with dynamic hyperinflation, which increases the work of breathing and causes dyspnea and potential exercise

Procedures: Initially, a clean mouthpiece was placed on the tube of the spirometer. Then, the nose clip was put in the subject nods to prevent the air escaping through the nasal passageway. The subject has been asked to take a deep breath and expire all the air in the tube to get the FVC value. This procedure had to be repeated again, and the subject was asked to expire as fast and as hard he/she could to get the FVE1 measurement. Afterwards, this was repeated in supine position. Also, this step was duplicated

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 FRC or Functional Residual Capacity is defined as the measurement of air in the lung after the patient has exhaled. Patrick Neligan MD is quoted saying “It is a space in which gas exchange continues to occur throughout the respiratory cycle, which makes sense as blood is continuously passing through the lungs. If there were no FRC, we would be continuously reabsorbing carbon dioxide” (Neligan 2002, Critical care tutorials website, pulmonology, why do we use PEEP). The means that larger the space the more oxygen is absorbed. If there is a smaller space because of a respiratory ailment, there is less lung space

Translated into physiological values: Total lung capacity (TLC) decreases; Vital capacity of the lung(VC) decreases ; Functional Residual capacity(FRC) decreases if caused by parenchymal lung disease the gas exchange mechanism decreases as well.

Functional residual capacity or FRC is the volume of air that remains in the lungs at the end of each normal expiration. It is equal to the expiratory reserve volume plus the residual volume. This particularly, is a very important lung function. After tidal respiration, the gas left inside the lungs prevents the collapse of the alveoli and helps maintain the normal process of respiration. Without the FRC, there would be large fluctuations in alveolar gas concentrations which could affect the normal cycle of respiration because it would require the alveoli to work twice as hard for gas to circulate in the lungs. The FRC increases with an increase in body mass, decreased lung recoil while it decreases in obesity, with postural changes and in
