Adaptive Servo Ventilation

A range of emotional factors including fear, stress, anxiety, and pain can affect a person’s ability to breathe correctly and efficiently. The healthcare environment involves a considerable amount of stress and anxiety. Patients often demonstrate fear for their own well- being or

18 study data were derived from the apnea database (PhysioNet) corresponding to MIT/BIH database. AirFlow, SaO2, Abdominal and Thoracic Movements were obtained from full PSG records. Each record includes a period of nearly eight hours and signals annotation is done minute-by-minute. A minute is labeled as an apnea case if it contains at least one condition of apnea or hypopnea, otherwise labeled as a non-apnea. The patients mean age and weight are between 27 to 63 years (4810.8) and 53 to 135 kg (86.322.2), respectively. PhysioNet data are classified in two categories: Apnea Group (Class A, more than 100 minutes of apnea, mean age: 50 years in range of 29 to 63 years) and Normal Group (class C, less than 5 minutes of apnea, mean age of 33 years

The three major life-breathing concerns for a patient is a disruption of the airway, breathing, and circulation. When a patient goes into cardiac arrest due to pre-existing conditions or trauma, an EMT will initiate the steps of cardiopulmonary resuscitation (CPR) and hopefully using an available automated external defibrillator (AED). However, some patients due to having a terminal illness, age, or personal choice does not want to be resuscitated or have

Sometimes when a patient is on the more common form of mechanical ventilation for an extended time or if the patient has undergone respiratory failure, their respiratory muscles have a tendency to become weak. With the use of this biphasic cuirass ventilation method they can have the opportunity to build and strengthen those muscles which, in return, can allow them to be weaned from the ventilator

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

Obstructive rest apnea is a typical unending illness in Western culture whose commonness is evaluated at 2% of ladies and 4% of men in the overall public. It is portrayed basically by repetitive impediment of the upper aviation route that outcomes in oxyhemoglobin desaturation and occasional feelings of excitement from rest. It now creates the impression that even gentle to direct rest apnea is connected with the improvement of hypertension, diabetes mellitus, and cardiovascular danger. With expanding corpulence, rest apnea can add to the advancement of daytime alveolar hypoventilation (weight hypoventilation disorder), cor pulmonale, and candid respiratory disappointment. Subsequently, given its high pervasiveness and grimness, rest apnea represents a huge clinical weight to Western culture.

Leading to dyspnea, which is defined by the American Thoracic Society (ATS) as ‘a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity’. Almost all patients with IPF experience progressive dyspnea, resulting in a major impact on their quality of life. Dyspnea is a sign of serious disease of the airway, lungs, or heart. The onset of dyspnea should not be ignored; it is reason to seek medical attention. Later leading to more severe symptoms, such as always being tired, from lack of oxygen in the body, resulting in patients contracting pulmonary hypertension, heart failure, and pneumonia. Patients diagnosed with IPF have a long fight ahead, they will need their loved ones full support going through treatment and day to day

Sleep apnea was also a topic in this chapter that caught my attention. My father was diagnosed with sleep apnea a few years ago and it was pretty scary to learn this could block his airway and stop him from breathing. Thankfully there are at least some preventive measures for the short and long term. When he was first diagnosed he was given a machine that helps sustain pressure for airways so that they do not collapse. This is mentioned in our text as "continuous positive airway pressure(CPAP)" therapy that uses a device "that increases air pressure in the throat so the airway remains open"(p. 155).

Consequently, there are numerous benefits of Neurally Adjusted Ventilation Assist (NAVA) for patients meeting the qualifications to both the patient and the medical team. First of all, the EdiCatheter can be used as an assessment tool for the patient. If you were to drop the catheter down a patient’s esophagus you could assess the diaphragm’s muscle strength which would determine if there was a possible neuromuscular problem occurring. (Kylie- KC Children’s) A patient placed on NAVA will also require less sedation to maintain comfortability, as a result this will let the patient’s respiratory muscles work while still being supported. NAVA will also help the nurses and doctors determine the appropriate level of sedation based upon the ventilator

Many patients with obstructive lung diseases such as Chronic Obstructive Pulmonary Disease (COPD), asthma, pneumonia, and Acute Respiratory Distress Syndrome (ARDS) need mechanical ventilation in order to support their breathing and restore respiratory function. However, mechanical ventilation can cause further lung injury. The mortality rate for patients requiring mechanical ventilation is about 35% and this rate increases to about 53% for the elderly [1]. Also, with increasing age, the severity of ventilator-induced lung injury (VILI) increases [2]. In general, with increasing age, the dynamic lung function and respiratory mechanics are compromised. In this study, several simulations are carried out to estimate these changes and understand

In a study used to determine the efficacy of paced breathing on insomnia and vagal activity 14 people with self reported insomnia (SRI) and 14 people who reported to be good sleepers (GS) were utilized to test the hypotheses that paced breathing would aid those with insomnia in falling asleep (Tsai, Kuo, Lee, & Yang, 2014). The study measured variables such as sleep quality, sleep effectiveness, Heart rate variability, and cardiac vagal tone. For the individuals to be allowed in the SRI group they had to have difficulty falling asleep, staying asleep, or trouble with waking up too early and not being able to go back to sleep more than 3 times per week, for 6 continuous months. All subjects of the study had to be between 20-25 years old and have a BMI within the normal range for their height and weight (18.5-24.5 Kg/m^). The subjects all had regular times that they went to bed and woke up and none reported having any history of sleep disorders such as sleep apnea or periodic limb movement, substance abuse,

When looking at these two modes of ventilation in 2012, A/C-VC is flow-cycled, time cycled ventilation, A/C-PC is pressure-targeted, time cycled ventilation.15 There are no automatic adjustments from the ventilator in either of these modes. Further complications with mechanical ventilating patients with ARDS are alveolar over distention, opening and closing of the alveoli, oxygen toxicity, biotrauma. This can further affect the pulmonary and systemic system from the alveolar over distention that can cause more lung inflammation and lead to multiple organ system dysfunction. A/C-PC and A/C-VC both have advantages and disadvantages that will benefit patients with ARDS, which a clinician with great skill can implement for the benefit of the patient following hospital protocols and that is more important than the specific mode of ventilation for complex ARDS patients. Doctor John J. Marini said "I will argue that pressure regulation is safer than flow-regulated volume

CPAP (continuous positive air pressure) machine and oral appliances are the most common and effective devices available in the market.

When T-tube and CPAP were compared in the Study (108), it showed that use of T-tube did not impair arterial oxygenation. Further it showed that extubation with T-tube could be superior to CPAP when the pattern of change in PaO2/FiO2 was taken into consideration to predict extubation outcome. The PaO2/FiO2 showed an initial decline and then increasing trend in case of T-tube whereas it had a declining trend in CPAP group. Study by Cekmen N et al. had contrary result showing the number of unsuccessful weaning being higher in T-tube group as compared to CPAP group. However the hemodynamic parameters and arterial blood gases analysis was comparable within and in between CPAP and T-tube group (113).

Pedersen et al9 compared oesophageal and pharyngeal pressures in infants on CPAP and found that the pharyngeal pressures were proportional to the set flow rate and had better accuracy. Oesophageal pressures were lower because of an anticipated downstream reduction in pressure as the air flow enters the oesophageal spincter9, 50. Hence, we have used pharyngeal pressure for measuring the CPAP in this study.
