Medical Ventilator
Medical Ventilator is a machine that mechanically moves air in and out of the lungs. It always be used to provide breathe for a patient who is physically unable to breathe, or breathing insufficiently. This is because this machine is able to help raise the oxygen level for these patients, and also to improve the ventilation, improve the ventilation function and reduce power consumption and save breath cardiac reserve capacity. My research is as follows:
To begin with, Medical Ventilator can deal with some tissue or systems’ problem, like the muscle tissue or respiratory system. The Respiratory system is a biological system consisting of specific organs and structures used for the process of respiration. It has two functions: breathing, and exchanges gases. The respiratory system aids in breathing, and air is inhaled through the nasal and oral cavities. It moves through the pharynx, larynx, trachea and bronchi into the lungs. Then air is exhaled, flowing back through the same pathway. What’s more, Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through the alveoli. Oxygen from inhaled air diffuses from the alveoli into

pulmonary capillaries surrounding them and then into the bloodsteam. Meanwhile, carbon dioxide from the blood diffuses from the capillaries into the alveoli, and is expelled through exhalation. Furthermore, Medical Ventilator plays an important role in the treatment of some disease and injury. People always use it when they have some damage on their lungs, like lung can cancer, Chronic obstructive pulmonary disease, which is a lung disease, or Pneumonia. Also, when people get hurt in their brain or stroke they will use this. All of those diseases and injury may cause difficult or labored respiration, so Medical Ventilator will be a good way to supply air by using a mask, BiPAP, or through a tube to help the people to breathe. What’s more, based on the function of Medical Ventilator, it is clearly identified that the benefit of Medical Ventilator is to help the patient breathe easily and reduce the pain of breathing difficultly. Medical Ventilator will preserve a stable airway to helps the patient get oxygen as much as possible. However, the Medical Ventilator not only has benefits, but also have risks. First, it may cause infection because the germs may enter the lung through the artificial airway. Second, The breathing tube of mechanical ventilator also makes it hard for patients to cough. Third, if patients use the mechanical ventilator frequently, it may prolong the dying process for them. Last but not least, physicians and other people may face two important ethical problems in regard to ventilator-dependent patients in the medical rehabilitation environment , which are: the cost of employing the respirator and the accompanying allocation issues entailed in that consideration.
Also, as we know, there are some risks in using the Medical Ventilator, and use Medical Ventilator for the patients who just finish the surgery, may cause infection and may aggravate their illness. However, the Medical Ventilator has played an important role in supply air to patients in order to help them breathe. Therefore, Should physicians give the Medical Ventilator to patients would be a worth pondering

This essay describes how the anaesthetic machine and airway management equipment are prepared in operating theatres and discusses how they are ensured safe for use. It evaluates the Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines related to safe practice and the preparation of the ET tubes, laryngeal masks, guedels, Naso pharyngeal airways and the laryngoscope. The function of the anaesthetic workstation is to deliver a mixture of anaesthetic agents and gases safely to the patient during the induction process and throughout surgery. In addition, it also provides ventilation to support breathing and monitors the patient’s vital signs to minimise the anaesthetic risks to the patient whilst in the care of health professionals. The pre-use check is vital to patient safety as an inadequate check of the anaesthetic machine or airway management equipment can and does lead to significant harm of the patient including mortality (Medicines and Healthcare Products Regulatory Agency (MHRA), 2008 and Magee, 2012).
BiPAP is a form of noninvasive mechanical ventilation used on patients that have acute respiratory failure. Many of these patients go on noninvasive ventilation due to COPD exacerbations that are infectious, with congestive heart failure, and ventilator parameters based on their clinical assessment and changes in arterial blood gases. Two different studies were conducted on COPD patients, using a BiPAP machine to improve exacerbations and their activities of daily living. There are many positive outcomes for using these noninvasive ventilators however when used incorrectly, negative outcomes or not changes at all are always possible.
A do not resuscitate order for patients who have emergency surgery is an “independent risk factor for poor surgical outcome and postoperative mortality” (Kelley , 2014 pg 1 para 3) and the probability of returning patients to their previous level of functioning is higher for CPR performed during the peri-operative period (Kelley , 2014).

...ering to medication antibiotics which fight off infections, bronchodialators used to decrease dyspnea relieve broncho spasms , and pulmonary rehabilitation help betters their condition. The nurse expects the patient to be able to perform suitable activities without complication, avoid irritants that can worsen the disease (contaminated air) and reduce pulmonary infection by abiding to medications.
In clinical experience, it is seen that many patients in the Intensive Care Unit (ICU) are on mechanical ventilation. These patients range from having head trauma, heart surgery and respiratory problems yet there is no clear, concise systematic standard oral care procedures noted on the different floors in the hospital. Oral care is a basic nursing care activity that can provide relief, comfort and prevention of microbial growth yet is given low priority when compared to other critical practices in critically ill patients. The Center for Disease Control reveals that Ventilator-Associated Pneumonia (VAP) is the second most common nosocomial infection that affects approximately 27% of critically ill patients (Koeman, Van der Ven & Hak, 2006). The purpose of this paper is to explore Lewin’s change theory in the clinical setting by implementing standard oral care on preventing VAP thereby improving patient care.
Many interventions are already in place to improve patient outcomes while on a ventilator. For example, elevating the head of the bed to 30 degrees, preventing venous thrombus via sequential compression devices or anticoagulant drugs, initiating early mobilization and practicing good hand hygiene were among the interventions listed by Fields, L.B., 2008. However, oral care was n...
Caring for people is my passion. My senior year of high school is when I witnessed my grandmother live on a ventilator for about a week. It awakened a new level of passion in me to care for people with cardiopulmonary problems. The Respiratory Therapy Care profession has intrigued me with how they improve the quality of life in their patients. I will enjoy working closely with patients in addition to working high tech equipment. By entering into this program and graduating out of this program I know that this will satisfy my personal goals for the next five years in many ways. The continues challenges of trying to figure out what’s wrong the heart that day or what’s wrong with the lung the next day will always keep me on my toes. It will always

Additionally, the clinical staff has shown very low level of confidence in the RR documentation on observation chart. Lack of time, laziness, lack of training and knowledge and unawareness of the importance of the respiratory assessment are main reasons to neglect this important aspect of nursing as stated in this study (Philip, Richardson, & Cohen,
Ventilator is a machine that helps someone breathe, and also ease oxygen flow through the body. Most people on life support are usually brain death. Brain dead patients are legally considered dead. People sometimes confused brain dead with coma; however people in coma will have some neurological signs. A life support machine maintains
The role of the nurse in the preoperative area is to determine the patient’s psychological status to help with the use of coping during the surgery process. Determine physiologic factors directly or indirectly related to the surgical procedure that may cause operative risk factors. Establish baseline data for comparison in the intraoperative and postoperative period. Participate in the identification and documentation of the surgical site and or side of body on which the procedure is to be performed. Identify prescription drugs, over the counter, and herbal supplements that are taken by the patient that may interact and affect the surgical outcome. Document the results of all preoperative laboratory and diagnostic tests in the patient’s record
The mechanism of breathing or pulmonary ventilation consists of inspiration and expiration. In a resting person the action of inhaling and exhaling is done passively. Inspiration involves air flowing into the lungs whereas expiration involves gases leaving the lungs. The muscles involved in the act are diaphragm and intercostal muscles. The diaphragm is an essential part of the breathing process. It is a muscle located underneath the lungs and has an ascending and descending motion (Better Health Channel, 2013). Intercostal muscles are located between ribs and differentiate between external and internal. External intercostal muscles activates in inspiration whereas internal intercostal activates in expiration. The phases of breathing also involve pressure and volume Pressure includes the pressure in the alveoli known as intrapulmonary pressure and atmospheric pressure, which refers to pressure expelled by the gases encompassing the body. Volume may refer to thoracic of lung. In pulmonary ventilation, volume adjustment leads to pressure changes. Pressure change in turn leads to gases equalizing pressure. In inspiration the muscles contract hence the diaphragm descend and the rib cage ascend. There is an increase of thoracic or chest cavity capacity. Intrapulmonary pressure is decreased and thoracic intrapulmonary volume increase. Air flows along the pressure gradient equalizing to atmospheric pressure. In expiration muscles are relaxed. Thus the diaphragm rises whilst the rib cage moves down. There is a decrease in thoracic and intrapulmonary volume whilst intrapulmonary pressure increases. Air is forced to out of the lungs down the pressure gradient (Marieb & Hoehn, 2013).

Operate only when needed: This is the most important function of a mechanical ventilation system, since it is associated with the costs of electricity. It should not operate unnecessarily when there is no need of indoor/outdoor air exchange. For example air exchange is not required when there are no occupants in the house, and when there is a sufficient air exchange due to wind or stack effect.
