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).

Oxygen Saturation that falls as low as 91% on room air at rest and after exertion

Stretch-induced lung injury may not occur if lung compliance is not greatly reduced. However, the benefit of ventilation with a lower tidal volume was independent of the static compliance of the respiratory system at base line, suggesting that the lower tidal volume was advantageous regardless of lung compliance. Variations in chest-wall compliance, which contributes to compliance of the respiratory system and is reduced in many patients with acute lung injury and the acute respiratory distress syndrome,39 may have obscured a true interaction between tidal volume and base-line lung compliance.

Participants in this study performed two types of tasks: chest wall maneuvers and speech breathing activities. The chest wall tasks consisted of many different maneuvers, including isovolume, vital capacity, rib cage capacity, abdominal capacity, and relaxation maneuvers. Isovolume maneuvers were conducted, in which the participant displaced volume back and forth from the abdomen to the rib cage with a closed larynx. In vital capacity maneuvers, the participant inspired maximally from resting expiratory level then expired maximally. The minimum and maximum rib cage volumes during the vital capacity maneuver determined rib cage capacity maneuvers, and abdominal capacity maneuvers consisted of the range of abdominal volumes while the participant held their breath. Lastly, relaxation maneuvers were performed in which the participant completely relaxed the chest wall muscles while keeping their larynx closed. Speech breathing activities consisted of two measures: extemporaneous speech and reading speech. For the extemporaneous speech activity, the participant spoke 10 to 20 breath groups about the topic of his choice. For the reading speech activity, the participant read a 12-sentence

The same method was utilized to find expiratory reserve volume. Except, the I-beam cursor was dragged in-between the trough of a normal and maximum exhalation. As for tidal volume, it was discovered using the absolute value between the peak and the trough of a normal wave. The last data to be found using the BIOPAC was the subject’s vital capacity. Here, the I-beam cursor was dragged from the peak of the maximum inhalation to the trough of maximum exhalation.

The purpose of this lab was to understand how mammalian pulmonary and circulatory systems increase the delivery of oxygen to cells during exercise. The systems were examined by measuring pulse, vital capacity, ventilation rate, and the blood pressure at rest and immediately following short exercise. From these observations we measured the height, weight, body mass index (BMI) and smoking status in order to determine what may affect exercise (Barrilleaux, 2014).

“The BSL Respiratory Effort Xdcr SS5LB was attached to the Biopac Systems MP36 and then was attached to the participant’s chest, underarms, and above the nipple line” [4]. Respiratory monitoring was done throughout the experiment. The subject was seated upon a Gold’s Gym 390R Cycle Trainer stationary bike. The Nonin Pulse Oximeter was used to monitor oxygen saturation levels in subjects’ blood and to measure changes

A Comparison of Total Caloric Expenditure and Respiratory Exchange Ratio in Different Modes of Exercise

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

Hyperoxia is used to test for diffusive limitations in respiratory pathways. If high levels of oxygen does not increase the rate of oxygen use, then non diffusive, convective, or pertusive limits to aerobic capacities are indicated. Studies of exercising humans show that high levels of oxygen do increase the maxim rate of oxygen use. However, no exercising amphibians and reptiles have been studied.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.

In air-breathing vertebrates, the tidal volume of the lungs is the amount of air normally inhaled, while the lung capacity is the maximum amount of air inhaled. In this experiment, a round balloon is utilized to measure both the tidal volume and the lung capacity. Furthermore, students explored possible factors impacting the vital capacity. Students established that body position is one factor that has an impact on vital capacity. In this case, a standing position versus a seated position, provides more room for the expansion of the chest cavity, thus allowing more air to be inhaled, resulting in increased lung capacity.
