Oxygen injection site affects FIO2 during noninvasive ventilation.

BACKGROUND Most portable bi-level positive airway pressure devices are not equipped with air-oxygen blenders for precisely regulating oxygen concentrations, and supplemental oxygen must be added to increase the F(IO2). Very few studies have investigated the factors that affect F(IO2), and their conclusions have been inconsistent. We investigated in vitro noninvasive ventilation (NIV) parameters...

Influence of FIO2 on PaCO2 during noninvasive ventilation in patients with COPD.

BACKGROUND The administration of a high FIO2 to COPD patients breathing spontaneously may result in hypercapnia, due to reversal of preexisting regional hypoxic pulmonary vasoconstriction, resulting in a greater dead space. Arterial blood gas trends have not been reported in these patients. In a 31-bed medical ICU in a teaching hospital we prospectively investigated the response of 17 CO2-retai...

Noninvasive ventilation with helium-oxygen in children.

Most existing literature on noninvasive ventilation (NIV) in combination with helium-oxygen (HELIOX) mixtures focuses on its use in adults, basically for treatment of acute exacerbations of chronic obstructive pulmonary disease. This article reviews and summarizes the theoretical basis, existing clinical evidence, and practical aspects of the use of NIV with HELIOX in children. There is only a ...

Albuterol delivery during noninvasive ventilation.

HYPOTHESIS Albuterol delivered during noninvasive positive-pressure ventilation is affected by use of a nebulizer or metered-dose inhaler (MDI) and whether the leak port is in the hose or the mask. METHODS A lung model that simulated spontaneous breathing at 20 breaths/min was used. A bi-level positive-airway-pressure ventilator (Respironics S/T30) was set for an inspiratory positive airway p...

Bronchodilator delivery during simulated pediatric noninvasive ventilation.

BACKGROUND Noninvasive ventilation (NIV) is usually applied using bi-level positive airway pressure devices, and many of these devices use a single-limb patient circuit with an integrated leak port to purge the circuit of exhaled carbon dioxide. Sometimes bronchodilator therapy is indicated in pediatric patients, but there have been no studies of the optimal nebulizer position, with respect to ...
