Electromagnetic Biosensing of Tidal Volume

Intraoperative low-tidal-volume ventilation.

Low Tidal Volume Ventilation: Trust but Verify.

Despite affecting an estimated 4 –7% of patients in the ICU and having a high mortality rate, there are currently a limited number of therapeutic options to treat patients with ARDS.1,2 ARMA, the landmark ARDSnet trial in 2000, established the concept of lungprotective ventilation, where subjects with ARDS receiving mechanical ventilation were randomly assigned to a set tidal volume (VT) of eit...

Correlation properties of tidal volume and end-tidal O2 and CO2 concentrations in healthy infants.

We investigated whether breath-to-breath fluctuations in tidal volume (VT) and end-tidal O2 and CO2 exhibit long-range correlations and whether parameters describing the correlations can be used as noninvasive descriptors of control of breathing. We measured VT and end-tidal O2 and CO2 over n = 352 +/- 104 breaths in 26 term, healthy, unsedated infants (mean age +/- SD: 36 +/- 6 days) and calcu...

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,...

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...
