The results for simulated airway restriction are shown at figure and table 3. Airway restriction prevents air from diffusing into pulmonary arteries as a kind of blockage in the lungs. Based on the data, peak inspiratory flow, peak expiratory flow, forced vital capacity, forced expired volume in one second, and the ratio FEV1/FVC are affected by the simulated restricted airflow. Peak respiratory flow, peak expiratory flow, and forced expired volume in one second have lower values in the restricted airway. The forced vital capacity is higher in the restricted airway simulation. The ratio FEV1/FVC which is 76% in an unrestricted airway dropped to 30% in the restricted airway simulation. This means that restricted airway is often accompanied by
The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.
There are numerous different challenges that the paramedic will face in attempting to keep an airway patent. These challenges vary from patient to patient depending on their condition. One challenge in keeping a patent airway the paramedic will face is trying to maintain the airway of a trauma patient. Trauma patients make it difficult to maintain an airway due to the traumatic damage, especially if it has affected the face and neck regions.
Data: Pulmonary function testing dated 2010 showed moderately severe obstruction with positive bronchodilators response. Normal lung volumes. Evidence of air trapping. Severely reduced diffusing capacity for carbon monoxide.
ation that I will be discussing is Airway Pressure Release Ventilation (APRV). I have not had an opportunity to use this mode, so I thought I would research it for this assignment. “The degree of ventilator support with APRV is determined by the duration of the two CPAP levels and the mechanically delivered tidal volume. Depends mainly on respiratory compliance and the difference between the CPAP levels. By design, changes in ventilatory demand do not alter the level of mechanical support during APRV. When spontaneous breathing is absent, APRV is not different from conventional pressure-controlled, time-cycled mechanical ventilation”( Putensen, C. )APRV is a form of improved pressure ventilation allowing unrestricted spontaneous breath at an
The lung function tests showed a moderate degree of airflow obstruction with normal gas transfer factor which would be consistent with moderate degree COPD.
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).
3. Teach patient effective ways to cough and breathe (deep breath, hold for 2 seconds and cough 3 times with their mouth open).
Both rapid, shallow breathing patterns and hypoventilation effect gas exchange. Arterial blood gases will be monitored and changes discussed with provider. Alteration in PaCO2 and PaO2 levels are signs of respiratory failure. Patient’s body position will be properly aligned for optimum respiratory excursion, this promotes lung expansion and improved air exchange. Patient will be suctioned as needed to clear secretions and maintain patent airways. The expected outcome is that the patient’s airway and gas exchange will be maintained as evidence by normal arterial blood gases (Herdman,
The purpose of pulmonary function testing is to determine the overall function of the lungs as it relates to how much gas moves in and out of the lungs, how fast the gas exchange occurs, the stiffness of lung and chest walls, the diffusion characteristics of the alveolar-capillary membrane, and how well lungs respond to therapy (REF 15). Vital capacity of the lungs is measured when, after taking a long, deep breath, the patient exhales the maximum possible volume (REF 15). When the expiration of the volume is forceful, it is defined as forced vital capacity (FVC), which it is the most common way to measure vital capacity (REF 15). Mr. Kostas’ result of FVC 4.1L are only 85% of the expected normal value. FVC is reduced in patients with
There are two main categories of diseases that can affect the lungs, which are obstructive diseases and restrictive diseases. These lung diseases can have detrimental effects on the lung because they can result in decreased airway size, swollen or loss of alveolar sacs, and ultimately reduced gas exchange. Lung diseases, as well as the overall function of the lung can be evaluated using a method known as spirometry. Spirometry is a tool used to evaluate the breathing mechanisms of a patient and allow doctors to detect pulmonary diseases in patients displaying abnormal lung function. Spirometry can consist of static and dynamic tests to measure variables such as vital capacity, which is the highest volume of air that can be exhaled out of the
Patients like Ralph has an increased airway resistance due to airway obstructions due to bronchoconstriction, mucous buildup and tissue swelling. This means that the expiratory cycle of breathing must use higher pressures of force to move air out of lungs. Work of breathing depends on the pressure changes and differences in the ventilation system of the body to move air into and out. In patients, like Ralph, with obstructive lung disease like asthma, their work of breathing is increased as they breath at higher lung volumes to move air (increased FRC). Expiration is normally effortless and does not require the use of any muscles like diaphragm or accessory muscles but depends on the elasticity of elastic connect lung tissue. In obstructive
The mannequin is based on a commercially available medical training patient mannequin. This mannequin supports many clinical activities. Complete airway management can be practiced including mask ventilation, endotracheal and endobronchial intubation, cricothyrotomy and trans tracheal jet ventilation. The airway can be made "difficult" in several ways including changes in the neck/head alignment, incorporation of an intraparietal mass, and laryngospasm. Other clinical features supported by the mannequin include ability to placemen of peripheral and central intravenous lines, a thumb that can be stimulated by real clinical nerve stimulators (and responds appropriately depending on what drugs have been given), palpable radial and carotid pulses,
The main characterizing feature of Chronic obstructive pulmonary disease is that there is limitation of airflow because the smoke of cigarette directly damages the epithelial cells of the
Acute respiratory distress syndrome (ARDS) is a life-threatening condition which can be triggered by aspiration pneumonia. It is when the lungs become severely inflamed that causes increased permeability in the pulmonary vasculature and hypoxemia. The oedema and fibrin can cause stiffening of the lungs which decreases the lung compliance and also reduces the vital capacity of lungs. The inflammation of alveoli causes collapse which further reduces the concentration of the oxygen in the blood. Acute lung injury (ALI), on the other hand, is a subset of ARDS with less severe impairment in oxygenation (Ranieri, 2012). Protective ventilation strategy aims to prevent the aforementioned conditions by lowering the airway pressure and tidal 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.,
