Effect of ambient temperature and cardiac stability on two methods of cardiac output measurement.
The dependence of cardiac output measurement precision on ambient temperature and cardiac output stability was assessed by concurrent continuous and bolus thermodilution methods in postoperative cardiac surgery patients. The degree of agreement between the two methods was depended on room temperature (0.1 L/min for each degree below 25 degrees C). The agreement was also closer in trials where cardiac output was stable (< 10% variation). The continuous thermodilution method shows sufficient agreement with the bolus method for use in critical care; however, improved precision of cardiac output thermodilution measurements can be achieved by use of correction factors for cardiac instability and for ambient temperature.

Visitor and nurse satisfaction with a visitation policy change in critical care units.
Studies have addressed the visitation needs of visitors and patients and the impact of visitation policies on nurses, but few studies compare the level of satisfaction between visitors and nurses when visitation policies change. The objectives of this study were to investigate whether a more liberal intensive care unit visitation policy satisfactorily met the needs and expectations of visitors and nurses.

Avoiding respiratory excursions: obtaining reliable pulmonary capillary wedge pressures.
The pulmonary capillary wedge pressure (PCWP) value provides valuable assessment data to guide therapeutic interventions. Proper interpretation of PCWP becomes complicated when respiratory excursions are imposed upon the pressure waveform. Critical care nurses and advanced practice nurses who understand the mechanics of this respiratory effect can accurately interpret the PCWP.
