Equipment review: Tracheal gas insufflation

47cc-2-2-043 Introduction Tracheal gas insufflation (TGI) is an adjunctive ventilatory technique that delivers fresh gas into the trachea either continuosly or only during a specific segment of the respiratory cycle (phasic flow) [1-4]. Two mechanisms are responsible for improving the efficacy of conventional tidal breaths during TGI [5-7]. First, fresh gas introduced by the catheter during exp...

Oxygen Gas Phase Abundance Revisited

We present new measurements of the interstellar gas-phase oxygen abundance along the sight lines towards 19 early-type galactic stars at an average distance of 2.6 kpc. We derive O I column densities from HST/STIS observations of the weak 1355 Å intersystem transition. We derive total hydrogen column densities [N(H I)+2N(H2)] using HST/STIS observations of Lyman-α and FUSE observations of molec...

Gas-producing brain abscess due to peptostreptococcus.

A case of anaerobic streptococcus brain abscess was reported in which the cerebral lesion appeared on CT as a ring-enhanced mass, and gas bubbles were seen following corticosteroid administration without antibiotics. Surgery revealed no encapsulation. Surgical drainage of the cavity and treatment with antibiotics and corticosteroid were ineffective. Excision of the abscess and treatment with ch...

Cold Sterilization of Cardiac Catheterization Equipment with Ethylene Oxide Gas.

OCCASIONAL infections in sites of venous cutdowns and an episode of fever in a patient following cardiac catheterization caused us to review the procedures used in this laboratory for preparation of catheterization equipment. Materials not susceptible to damage by wet heat (surgical instruments, syringes and needles, drapes) are sterilized in a steam autoclave. Polyethylene catheters, cuvette o...
