Mode:
Flinders Medical Centre’s preset mode for mechanical ventilation is Synchronised intermittent mandatory ventilation (SIMV).
SIMV achieves a mandatory minute ventilation by,
Mandatory controlled breathing
Assisted breaths which are synchronised with a patient trigger
Spontaneously triggered and patient controlled breaths often with assistance (Tol & Palmer 2010).
Mandatory breaths deliver a preset volume over a set time, Synchronised breaths still give mandatory breaths which are preset but are synchronised with respiratory effort reducing the danger of breath stacking causing barotruama, and spontaneous breaths are initiated and controlled by the patient including respiratory rate and tidal volumes, and may be assisted with added pressure (Aitken, Elliott & Chaboyer 2012).
For Mr J, SIMV is appropriate because it supports him while he is initially unresponsive, and when his breathing starts to improve, it enables his dependance upon mechanical ventilation to be weaned, and lets him increasingly contribute to his minute ventilation building up his own strength (Tol & Palmer 2010).
Mr J was extubated only 48 hours after admission so SIMV was an appropriate choice.
Mandatory Breath Type:
Flinders Medical Centre’s preset mandatory breath type is volume control.
Volume controlled breathing includes,
Preset tidal volume and minute volume being reached consistently with the ability to manage carbon dioxide elimination (Rose 2006).
A set tidal volume independent from the compliance and resistance ability of the lung, and if airway pressures are not monitored, injury can occur from over distention, barotrauma, and even lower cardiac output (Rose 2006).
Mr J’s peak plateau pressures (the pressures applied to the a...

...ing in a spontaneous breath by the patient, is a flow trigger set with the sensitivity at 3L/min.
A continuous flow of 3L/min travels through the circuit of the ventilator continuously, and so this means that for a patient to take a spontaneous breath, they will need to divert more than 3L/min of flow away from the ventilator to initiate a breath (Aitken, Elliott & Chaboyer 2012). If set too low, water or movement in tubing could cause auto triggering and result in patient ventilator asynchrony, but if set too high, it would be hard for a weak patient to initiate a breath (Chatburn 2012).
In relation to Mr J, he was unresponsive and not making any respiratory effort to initiate his own breathing, so the flow trigger will not be used. But as the sedation wears off it will be used and allow Mr J to breath with a small amount of effort.
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).
Ascertaining the adequacy of gaseous exchange is the major purpose of the respiratory assessment. The components of respiratory assessment comprises of rate, rhythm, quality of breathing, degree of effort, cough, skin colour, deformities and mental status (Moore, 2007). RR is a primary indicator among other components that assists health professionals to record the baseline findings of current ventilatory functions and to identify physiological respiratory deterioration. For instance, increased RR (tachypnoea) and tidal volume indicate the body’s attempt to correct hypoxaemia and hypercapnia (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). The inclusive use of a respiratory assessment on a patient could lead to numerous potential benefits. Firstly, initial findings of respiratory assessment reveals baseline data of patient’s respiratory functions. Secondly, if the patient is on respiratory medication such as salbutamol and ipratropium bromide, the respiratory assessment enables nurses to measure the effectiveness of medications and patient’s compliance towards those medications (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). Thirdly, it facilitates early identification of respiratory complications and it has the potential to reduce the risk of significant clinical
...roduces more blood lactate that it can reabsorb. At this point ventilation increases exponentially. The goal with lactate threshold training is to raise your threshold point to as close as possible to your maximum heart rate, and improve your ability to withstand that discomfort” (Messonnier, 2013). This concept was depicted by the trained participant. As stated in the introduction and discussion sections and depicted throughout the graphs one can conclude that the trained participant was in fact more fit and could consume more oxygen than the untrained participant.
This machine used an intravenous drip which was hooked up to the patient. The IV would start dripping a solution of saline. When the patient was ready they pushed a button and this solution would stop dripping. At this time the machine would release a drug called thiopental, better known as sodium pentothal, a general anesthesia for sixty seconds. After this the patient would be in a coma. A timer would stop the first drug and the release the next one called potassium chloride. This drug will cause a heart attack and the patient will die in their sleep.

An electrocardiogram (ECG) is one of the primary assessments concluded on patients who are believed to be suffering from cardiac complications. It involves a series of leads attached to the patient which measure the electrical activity of the heart and can be used to detect abnormalities in the heart function. The ECG is virtually always permanently abnormal after an acute myocardial infarction (Julian, Cowan & Mclenachan, 2005). Julies ECG showed an ST segment elevation which is the earliest indication that a myocardial infarction had in fact taken place. The Resuscitation Council (2006) recommends that clinical staff use a systematic approach when assessing and treating an acutely ill patient. Therefore the ABCDE framework would be used to assess Julie. This stands for airways, breathing, circulation, disability and elimination. On admission to A&E staff introduced themselves to Julie and asked her a series of questions about what had happened to which she responded. As she was able to communicate effectively this indicates that her airways are patent. Julie looked extremely pale and short of breath and frequently complained about a feeling of heaviness which radiated from her chest to her left arm. The nurses sat Julie in an upright in order to assess her breathing. The rate of respiration will vary with age and gender. For a healthy adult, respiratory rate of 12-18 breaths per minute is considered to be normal (Blows, 2001). High rates, and especially increasing rates, are markers of illness and a warning that the patient may suddenly deteriorate. Julie’s respiratory rates were recorded to be 21 breaths per minute and regular which can be described as tachypnoea. Julies chest wall appeared to expand equally and symmetrical on each side with each breath taken. Julies SP02 levels which are an estimation of oxygen
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

The purpose of the respiratory system is breathing which is also known as ventilation. The process of cyclically moving air in and out of the lungs so alveolar air that has given up oxygen and picked up carbon dioxide can be exchanged for fresh air from the atmosphere. Ventilation is accomplished from the system alternately shifting the direction of the pressure gradient for airflow between the atmosphere and the alveoli through the expansion and recoiling of the lungs. Contraction of the inspiratory muscles indirectly produces inflation and deflation of the lungs by continuously expanding and compressing the thoracic cavity with the lungs following its movements. Since energy is required to contract these muscles inspiration is known as an active process. Expiration is known as a passive process during quiet breathing because it is accomplished by elastic recoil of the lungs on relaxing the inspiratory muscles without energy. Ventilation involves two aspects, which are both subject to neural control. Firstly rhythmic cycling between inspiration and expiration and regulation of ventilation magnitude, which depends on the control of respiratory rate and depth of the tidal volume The lungs can be stretched to different degrees during the process of inspiration and then have the ability to recoil to their size before inspiration because of their elastic behavior. Pulmonary compliance is the term used for the dispensability of the lungs and their ability to stretch in response to a given change in the transmural pressure gradient. Elastic recoil refers to the ability of the lung to snap back to resting position during expiration. The lungs can be filled to about 5.5 liters when at maximal inspiration, and on the other hand emptied t...

In the case study it is the left lung that is in distress, and as the pressure increases within the left lung it can cause an impaired venus return to the right atrium (Daley, 2014). The increased pressure can eventually affect the right lung as the pressure builds in the left side and causes mediastinal shift which increases pressure on the right lung, which decreases the patients ability to breath, and diffuse the bodies tissues appropriately. The increase in pressure on the left side where the original traum... ... middle of paper ... ... 14, January 29).
For minute ventilation, in adults the breathing rate norms 12 breaths per minute, and tidal volume norms about 0.5L of air per breath (William D. McArdle, 2006). In case of intense exercises, soon as the breathing rate would start to increases to 35 to 45 breaths per minute, the tidal volume usually rises to 2.0L (William D. McArdle, 2006). The minute ventilation is reliant on tidal volume, the quantity of air going in and out per breath and the rate of breaths per minute (Sharon Plowman, 2007).
There are 2 types of breathing, costal and diaphragmatic breathing (Berman, 2015). Costal refers to the intercostal and accessory muscles while diaphragmatic refers to breathing using your diaphragm (Berman, 2015).It is important to understand the two different types of breathing because it is vital in the assessment of the patient. For example, if a patient is suing their accessory muscles to aid in breathing then we can safely assume that they are having breathing problems and use a focused assessment of their respiration. Assessing respiration is fairly straightforward. The patient’s respiration rate can be affected by anxiety so a useful to avoid this is to check pulse first and after you have finished that, while still holding their pulse point, check their respiration rate. Inconspicuous assessment avoids the patient changing their breathing because they know they are being assessed which patients can sometimes do subconsciously. Through textbooks and practical classes I have learned what to be aware of while assessing a patient’s respiratory rate. For example; their normal breathing pattern, if and how their health problems are affecting their breathing, any medications that could affect their respiratory rate and also the rate, depth, rhythm and quality of their breathing (Berman, 2015). The only problem I found while assessing respiration rate was I thought it seemed a bit invasive looking at the
