Opioids depress respiration and decrease chest wall compliance. A previous study in this laboratory showed that dopamine-D(1) receptor (D(1)R) agonists restored phrenic nerve activity after arrest by fentanyl in immobilized, mechanically ventilated cats. The reinstated phrenic nerve rhythm was slower than control, so it was not known whether D(1)R agonists can restore spontaneous breathing to l...

background ventilator-associated pneumonia (vap) develops in mechanically ventilated patients 48 hours after putting the patients on the ventilator. vap is the second most common nosocomial infection in neonatal intensive care units (nicu). objectives the current study was conducted to determine the rate, microbiological characteristics and outcome of vap in neonates admitted in the nicu of sho...

Total gas pressure, oxygen, temperature and salinity were measured at 50m on a mooring at the Hawaii Ocean Time series (HOT) station from January through September of 1997 and 1998 using a gas tension device (GTD) and a conductivity temperature depth and oxygen (CTD-O2) sensor (GTD–CTD-O2 instrument package). Our goal was to evaluate the precision and accuracy of the in situ total gas and oxyge...
