Talk:Biphasic cuirass ventilation

Huh??
As the ventilation provided by the cuirass is biphasic, it is possible to achieve both large breaths (tidal volumes) and a high respiratory rate (from 6 to 1200 breaths per minute).

That would mean 20 breaths per second. What organisms are we talking about? -- megA (talk) 17:04, 29 February 2008 (UTC)
 * I was also surprised by that, and assumed somebody had added an extra 0, so I went looking for references, and found High frequency ventilation which mentions 900 breaths per miute. So I guess 1200 is plausible. A Google search for "Biphasic Cuirass Ventilation" 1200 yields a few journal articles which seem to back up this claim, however I don't have access to the full articles and I am not sure whether I should add them as references purely on the basis of a Google summary. Perhaps somebody who is subscribed to these journals could do it. --Angelastic (talk) 17:51, 8 June 2008 (UTC)

merge with negative pressure ventilator
Agree I agree. Je.rrt (talk) 18:07, 2 October 2011 (UTC)

Disagree! Negative pressure ventilation is classically dependent on chest wall and lung recoil for exhalation is has significant minute volume limitations compared to Biphasic Cuirass Ventilation which has an active expiratory phase. Some authors have erroneously used the term negative pressure ventilation when referring to BCV, but BCV is not the same due to the positive exp phase. Dotmover (talk) 18:44, 19 October 2011 (UTC)
 * Biphasic cuirass ventilation is by definition negative pressure ventilation. Aside from spouting pulmonary function factors as a difference, does the BCV not administer negative pressure against the chest, causing an inhalation? If so, this would be negative pressure ventilation. Je.rrt (talk) 03:17, 27 October 2011 (UTC)

Negative pressure ventilation certainly uses negative pressure to effect lung inflation. BCV also use negative pressure to effect lung inflation however BCV has a cuirass applied positive pressure deflection that provides for exhalation. The pressure wave of NPV does not ascend above zero and does not provide for emptying of the lung. BCV offers much greater minute volume and high frequency application potential that NPV can not due to the time required for exhalation. Many think they know what this is. It is frequently equated with NPV and written off when it is a much more powerful clinical tool. This resource has become such an important reference when information on any subject is sought that this brushing off as something already known might be increased if BCV is grouped with NPV which its capabilities exceed and it is definitely different from.Dotmover (talk) 23:20, 1 November 2011 (UTC)
 * While its not specifically listed Nomenclature of mechanical ventilation suggests that its either positive pressure ventilation or negative pressure ventilation. Since BCV is 90% negative pressure ventilation, inclusion in the article is appropriate and a specific mention of its additional features is appropriate, but not for an entire article about it.

BCV has been successfully used on patients with:
 * Uses
 * Acute respiratory failure
 * Chronic obstructive pulmonary disease (COPD)
 * Congenital central hypoventilation syndrome
 * Neuromuscular (e.g., SMA, Duchennes, etc.)
 * Head and spinal injuries
 * Problems with weaning from positive pressure ventilation (PPV)
 * Ventilation during anesthesia in ear, nose, and throat (ENT) procedures
 * Cystic fibrosis (CF), and those who require physiotherapy
 * AIDS related lung disease
 * Asthma
 * Ventilation post-operation (e.g., post-coronary bypass, Fontan, Fallot, post-pneumonectomy)

Unlike conventional negative pressure ventilation, biphasic cuirass ventilation is able to quickly reduce any harmful buildup of CO2 using its active expiratory phase. Many published papers and case studies now show how effective BCV is at reducing CO2 buildup. It has also now been shown that the most effective ventilation frequency to reduce CO2 when using BCV is 60 cycles per minute. The oscillations caused by BCV assist in the removal of secretions which are a symptom of many respiratory diseases. Lastly, because BCV does not require the patient to be intubated or to have a tracheostomy, patients can have BCV at home.
 * Advantages

BCV has also been successfully used in a case of failed fiberoptic intubation, in microlaryngeal surgery, and after pediatric cardiac operations.

BCV has limited effect on patients who suffer from extreme obesity. BCV requires patients to maintain their own patent airway (patients with Obstructive Sleep Apnea may require additional assistance from positive pressure ventilation to open the airway). BCV should not be used on open wounds or burn victims.
 * Disadvantages
