The Manley ventilator

Intermittent mandatory ventilation during anaesthesia using the Manley Servovent ventilator.

The lungs of 25 patients were ventilated with intermittent mandatory ventilation (IMV) during anaesthesia using the Manley Servovent Model MS. This ventilatory mode is especially suitable for prolonged operations in which there is no need for muscle relaxation. While incorporating the advantages of spontaneous and mechanical ventilation, it is superior to both in selected cases. The Manley Serv...

When do the Manley-Rowe relations really hold?

The ventilator circuit and ventilator-associated pneumonia.

Historically, the relationship between the ventilator circuit and pulmonary infection was accepted as fact, without any scientific evidence. Hence the term, "ventilator"-associated pneumonia. Recent evidence, however, has demonstrated that the major sources of pneumonia in the ventilated patient are colonization of the gastrointestinal tract, with subsequent aspiration around the endotracheal t...

Isolation of the Patient from Ventilator

جداسازی بیمار از ونتیلاتور با هدف کاهش حمایت تنفسی وی و برگشت او به سمت تنفس ارادی است. زمان این فرایند با توجه به وضعیت بیمار و مدت اتصال او به دستگاه از چند روز تا چند هفته متغیر خواهد بود.

Probing with the ventilator

Neurally adjusted ventilatory assist operates through recordings of electrical activity of the diaphragm (EAdi). Barwing and colleagues found increases in EAdi in weaning-failure patients, although the values were not significantly different from weaning-success patients. Future studies will need to carefully control for the considerable biological noise evident in EAdi recordings.
