Respiratory physiology

the blood and systemic organs and/or CO2 elimination • May be accompanied by ventilatory failure 7 • Develops within minutes or hours as opposed to chronic respiratory failure that develops over several days, weeks or years CLASSIFICATION 2, 1 • Classification is mainly based on arterial blood gas (ABG) measurements • Regardless of the type, the final outcome is the same: functional failure of respiratory muscle leading to respiratory arrest • Distinction between different types is not always concrete ○ Type 1 (Hypoxemic) – Lung failure – PaO₂ < 60 mmHg and pCO₂ > 50 mmHg on room air (fraction of inspired oxygen [FiO₂] = 0.21) at sea level…

In the article, “Compressive Forces and Computed Topography-derived Positive End-expiratory Pressure in Acute Respiratory Distress Syndrome” (Cressoni et al. 2014), the researchers' hypothesis was that there was a direct correlation between lung recruitability and positive end-expiratory pressure (PEEP). This would validate the prevailing notion that higher PEEP is only for patients with higher lung recruitability. Previous studies have led to advancements in the field such as the switch from…

All of us have two lungs that are located in our left and right chest, and an average person has a lung capacity of approximately 4000 to 6000 cm. The capacity of human lungs can be said to be overbuilt when it is compared against our respiratory needs, since we only use about one third of our lung capacity (all-science-fair-projects.com, 2013). The lung capacity of a person usually depends on his or her gender, height, weight and…

collected will be evaluated to track the patient’s recovery process and the effectiveness of the incentive spirometry method. Disseminating Information The data collected including the analysis results will be printed in nursing journals such as the Journal of Emergency Nursing, the American Journal of infection control, and the Critical Care Nursing Clinics. Moreover, the information will be published in the practicum site to make it accessible to other nurses. This will allow future…

Discussion The results from the experiment demonstrate that respiratory frequency was higher and increased faster as exercise intensity increased in caffeinated individuals. The correlation between the independent (intensity of work rate) and dependent (respiratory frequency) variables for both the caffeinated and non-caffeinated groups was fairly good (R2 > 0.35) so there is some evidence that caffeine causes an increase in respiratory frequency. Tidal volume and alveolar ventilation were…

could indicate that she has type two respiratory failure. The main aims when treating type two respiratory failure is directed at reversing the underlying cause. Non-invasive ventilation with a tight-fitting facial or nasal mask with low levels of oxygen therapy often stabilizes these patients. When a patient is suffering from type two respiratory failure, the effectiveness of a peak flow would not affect the treatment given directly, especially when time critical, however, in none emergency…

Coaches Toolbox Coaches are very influential in their players lives. Their influence can be for the good of the player or can be detrimental to their performance. Some of the greatest coaches in history used a variety of sport psychology concepts and techniques to help their athletes reach peak performance. Since I am seeking a career in the field of coaching, it is essential that I gain the knowledge and know how to implement some of these techniques to help better my clients. This project…

perform deep breathing exercises, the patients in the experimental group had a significant elevation in FVC (mean effectiveness score of 23.80) and FEV (mean effectiveness score of 26.80). Refer to appendix for completed critiquing guideline. The hypotheses were supported, as the results showed the effectiveness of deep breathing exercises on pulmonary function (Mathew & D’silva, 2011). This study is relevant to guide my nursing practice as chronic obstructive pulmonary disease is common on the…

Liquid ventilation (LV) is a form of mechanical ventilation in which the lungs are insufflated with an oxygen-rich liquid, such as perfluorocarbon, rather an oxygen-rich gas mixture (1). There are two primary types of liquid-assisted ventilation: total liquid ventilation and partial liquid ventilation. In total liquid ventilation, the lungs are filled with perfluorocarbon to a volume equivalent to the lung’s functional residual capacity and a liquid ventilator is used to generate tidal breathing…

be reinforced when there is an increased ventilatory demand and a decreased expiratory timing, e.g. during exercise that leads to further air trapping and dynamic hyperinflation (DH).2,3 DH is defined as a variable enhancement in end-expiratory lung volume (EELV) above the relaxation volume (VR) of the respiratory system.4 A majority of scientific papers have stated DH as the major cause of dyspnea that occurs when end-expiratory flow (EFL) is worsened during bronchospasm or exacerbation.5…
