Factors Affecting The Human Capacity

Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle’s law.

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

The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.

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.

I interviewed Kit Mantz the Secondary Director for the district. Kit served as a principal/vice principal for three years at Whitehorse High School (WHS) before accepting a position in human resource and now the secondary director. This paper will discuss capacity and capability as it relates to the district and his time as principal at WHS.

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).

measure lung capacity, such as a spirometry to measure the volume of air a patient can blow out,

There are a number of reasons how an issue of an individual’s capacity has an effect on them making an informed choice including: physical health, mental health, religion, social class, the law, financial support, family support. Even though the list is endless, it is dependent on the individual and their personal situation which will determine the choice they make. The issues which may occur for someone making a decision may influence how an individual makes an informed choice, a few examples are:

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

The term “consent capacity” describes an adult’s ability to understand information relevant to making an informed, voluntary decision. A wide variety of diseases, disorders, conditions, and injuries can affect a person’s ability to understand such information.

When conducting the experiment two factors that could have affected my spirogram results are consciousness and visual perception. Our conscious can control our regular lung volumes and capacities by increasing or decreasing. This is because the mind is calculating the amount of inspiration and expiration. However, our breathing should be automatic and normal. Our visual perception when measuring the diameter of the balloon could also be inaccurate. This is because an inflated balloon is spherical shaped and does not directly lean against the ruler. Thus, our group had to go through many trials to get reasonable measurements.

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.,
