Acute respiratory distress syndrome is a disease process that requires specific, intensive care to increase the odds of patient survival. Due to the rapid and significant decline in a patient’s ability to maintain their respiratory status, ventilation techniques in treating acute respiratory distress syndrome are specific and unique. Multiple techniques have been studied extensively and a few stand above the rest in changing the mortality rate. High frequency percussive ventilation and high frequency oscillatory ventilation may be good options for ventilating some of the most critical patients.
Understanding acute respiratory distress syndrome (ARDS) is a critical aspect of managing a patients ventilatory needs. The definition of ARDS is “the

A simultaneously published trial called Oscar did not seem to have the same outcomes for patients receiving HFOV. There were multiple differences between Oscillate and Oscar, the most obvious being the use of the Novalung R100 in the Oscar trial. This was a new ventilator to the clinicians and hospitals participating in Oscar therefore, all clinicians participating in the study were required to go through 198 training classes to learn the specifics of the Novalung R100 ventilator. The outcome of the Oscar trial was only a 2 percent difference in mortality between conventional ventilation using a lung protective mode versus HFOV. This trial also had a similar outcome with vasoactive and neuromuscular blocking medications, Young et al states that this increase is due to the Novalung R100 not allowing for a patient to spontaneously breath on top of the oscillatory mode, therefore these medications were required to aide in patient- ventilator synchrony (Young, …show more content…
The oscillate trial reported a 35% conventional ventilation mortality rate compared to 41.1% mortality rate in the Oscar trial. Both trials demonstrated that mortality rates in utilizing HFOV is higher, 47% in the Oscillate trial and 44.1% in the Oscar trial. The Oscar trial patients who were randomized to the HFOV had a closer margin of mortality to the conventional group with only a difference of 2% favoring conventional ventilation, compared to the Oscillate trial which concluded with a difference of 12% also favoring the conventional ventilation
ICU patients suffer from a broad range of pathologies, requiring MV, sedation and use of multiples devices, which do not allow patients to protect their airway (Augustyn. 2007; Kollef. 2004).
Original research related to sedation management occurred in the year 2000 by Kress, Pohlman, O ' Connor, and Hall. Their findings served as a landmark study and initiated the impetus related to improving our sedation practices. According to Kress et al. (2000), daily interruption of sedation led to a decrease in the number of days on the ventilator in the intensive care unit. Several studies since this time have focused on the influence of sedation protocols, and outcomes. This paper will review the synthesis of the discovered studies and highlight the noted contraindications and inconsistencies. Also, explanations including a preliminary conclusion will be discussed.
Even though the consequence of saline instillation on a ventilator patient in the acute care setting is pneumonia or the patient may become hemodynamically unstable, this practice remain contentious, the practice of this procedure will also decrease the oxygenation. (Ayhan, et al., 2015),
Respiratory therapy refers to both a subject area within clinical medicine and to a distinct health care profession. During the 20th century, there were many health care fundamental transformations. Here are 10 possible predictions of what may occur in the future of respiratory care: (1) Less focus on raising PaO2 as a primary goal in managing patients with acute hypoxemic respiratory failure. (2) More attention to

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 nature of the study recommended in the paper was to assess the effects of protocolized weaning from mechanical ventilation on the total duration of mechanical ventilation for critically ill adults and ascertain differences between protocolized and non-protocolized weaning in terms of adverse events, mortality, quality of life, weaning duration, intensive care unit (ICU) and hospital length of stay (LOS) and explore the variation in outcomes by the type of ICU, type of protocol and approach to delivering the protocol.
This includes CPAP therapy, non-invasive ventilation, and lifestyle modification. The article includes a randomized control study to find the most efficient therapy for OHS. A CPAP therapy group and a NIV group were compared while the lifestyle modification group was the control. The study came to the conclusion that both CPAP therapy and NIV were more effective than the lifestyle modification group (Masa et al., 2015, p. 88). This study showed non-invasive ventilation was a better treatment since it improved respiratory functions (Masa et al., 2015, p. 95). However, the article does disclose long term treatment has yet to be studied and that is essential to proving NIV is superior to CPAP therapy (Masa et al., 2015, p. 93). I am happy I found this article due to the large patient base they used for their study. Overall, 351 patients were studied and since a lot of data was collected and compared, I trust their
The first ventilator induced lung injury that I want to discuss is pulmonary barotrauma. Pulmonary barotrauma is a lung complication caused by too much positive pressure forced into the lungs by a mechanical ventilator. Pulmonary barotrauma occurs when the alveolar begins to rupture due to elevated transalveolar pressure. Transalveolar pressure is a function of both the tidal volume and the overall compliance of the lungs. Researchers use plateau pressures to get an estimation of transalveolar pressure. Plateau pressures can be used as a tool to help measure for the risk of pulmonary barotrauma. Researchers have discovered that plateau pressures less than 30 cmH2O have shown to reduce the cause of pulmonary barotrauma. Guy W. Soo wrote
The literature found in this study was found by searching for relevant papers on MedScape. The keywords “chlorhexidine,” “ventilator-associated pneumonia,” “long-term ventilation” and “prevention.”
Research study concluded that the use of chlorhexidine gluconate reduces the rate of ventilator-associated pneumonia (VAP) even in patients at highest risk. (Halm & Amolar 2009). Compared with the normal saline solution had fewer cases of VAP (Boeser et al.2011).
Primary and long term treatment for CCHs is placement of a permanent tracheostomy. This most common invasive procedure involves the child being placed on positive pressure ventilation during the night. Depending on the severity of alveolar hypoventilation, some patients may require around the clock ventilation. The suggested ventilator mode for these patients iare spontaneous intermittent mandatory ventilation (SIMV). SIMV delivers a set number of fully assisted breaths whether the breaths are patient triggered, flow-limited trigger, or time-triggered. Additional spontaneous breaths by the patient are unassisted with no ventilator help. Ventilators should be used in the spontaneous intermittent mandatory ventilation (SIMV) mode. Another recommendation is the use of an uncuffed tracheostomy to minimize granuloma formation. Ventilator settings can compensate for air leaks around the tracheotomy tube by increasing volume and peak airway pressure as necessary. Mild hyperventilation in
The American Journal of Critical Care is a bi-monthly, peer-reviewed journal focused on improving the care of critically ill patients and their families. The authors provide resources in the form of research studies, case reports, reports on new techniques, clinical/basic science reviews, guest editorials and clinical studies. The editors strongly encourage works focused on collaborative practice and research targeted at health professionals caring for critical care populations.
In adults, there are ventilation strategies such as the pressure control ventilation (PCV) and airway pressure release ventilation (APVR) that are commonly used. The PCV is designed to prevent ventilator-associated lung injuries. Kacmarek et al. mention that “although there is not enough data showing that this machine improves the outcomes in ARDS, they have been successful in improving patient comfort (2014, p.615)”. Breathing support or oxygen therapies are all designed to help increase the oxygen flow throughout the body. These machines and types of therapy are needed since the cardio-respiratory system is failing to achieve its primary function, which is to deliver oxygen to the lungs and in turn the rest of the
The medical field is very fast-paced and new technological discoveries are constantly being made. When one thinks of new medical findings, cancer cures and surgery are common thoughts. However, a very interesting and slightly controversial discovery has been made in the neonatal world. The Neurally Adjusted Ventilatory Assist (NAVA) is “a form of partial ventilator assistance in which the machine delivers assistance in proportion to the electrical activity of the diaphragm (EAdi), as assessed by means of transesophageal electromyography” (Gianmaria Cammarota et al., 2011). It is meant to lower inspiratory pressure and respiratory muscle load in preterm infants (Gianmaria Cammarota et al., 2011). In other words, it helps the patient- whether they be an infant or an adult- breathe when their lungs aren’t able to aid in that process. M. Ferrer and P. Pelosi, authors of “European Respiratory Monograph 55: New Developments in Mechanical Ventilation” say that the signal from the EAdi is used to regulate NAVA, which then causes the airways to receive pressure. “With NAVA, both timing and the magnitude ventilator delivered assistance are controlled by the EAdi” (M. Ferrer & P. Pelosi., 2012, p 116). My research proves that NAVA can work better than pressure support ventilation (PSV) and can be used not only for neonates, but patients in the ICU that are affected by lung-related injury or illness that causes them to have difficulty breathing on their own; though there are
