Accuracy of tidal volume delivered by home mechanical ventilation during mouthpiece ventilation

Inaccuracy of tidal volume delivered by home mechanical ventilators.

Ideally, the inspired (tidal) volume (V(T)) provided by a volume-controlled ventilation device should not change when the pressure imposed on the ventilator varies. A bench study evaluation of V(T) versus pressure was performed on 10 commercially available devices. The difference between the desired V(T) and the observed V(T) reached 100 mL for some devices when inspiratory resistance was at it...

Mouthpiece ventilation: just a home-care support?

Noninvasive ventilation (NIV) is recognized nowadays as the first choice of treatment for COPD exacerbation. Compared with standard medical treatment, it can significantly reduce the intubation rate, hospital stay, nosocomial infection, and, above all, mortality rate.1,2 Physiological studies have shown that the mechanism of action of NIV in this population is the ability to sustain alveolar ve...

Tidal volume for mechanical ventilation of healthy lungs

Intermittent Positive Pressure Ventilation (IPPV) at our days is the gold standard treatment for patients requiring mechanical ventilation during general anesthesia and intensive care.1 The principal goals of IPPV are: improve tissue oxygenation, reduce hypercapnia and the related respiratory acidosis and reduce the work of breathing of the patient.1 Despite its important therapeutic functions,...

Home mechanical ventilation

Definition and goals ofhome mechanical ventilation Born during the polio epidemics of 50 years ago, home mechanical ventilation has evolved towards two distinct concepts-a life support system for patients without respiratory independence (high cervical spinal cord injury, end stage neuromuscular disease, or chronic obstructive pulmonary disease), and elective therapy for patients with progressi...
