Outcome from cardiopulmonary resuscitation (CPR) at community hospitals is seldom reported in the literature. Data regarding long-term functional status of CPR survivors are virtually nonexistent. We retrospectively reviewed the medical records of all patients receiving CPR during 1989 at a community teaching hospital to determine survival to hospital discharge from CPR. ⋯ We believe survival from CPR at community teaching hospitals is comparable to university hospitals. Additionally, patients who survive in-hospital CPR to hospital discharge have a 54 percent chance of being alive a mean of 31 months postdischarge with most being able to live independently. Further work is needed to validate these long-term functional status results.

The proliferation of alarms on equipment in ICUs contributes to a level of noise that can disturb both patient and staff. To determine whether these alarms are identifiable by sound alone to our ICU staff, we recorded 33 audio signals commonly heard on the ward, 10 of which we defined as critical alarms. One hundred subjects (25 physicians, 41 nurses, and 34 respiratory therapists) listened individually in a quiet room to the tape recording that consisted of 10 s of audible followed by a 10-s pause for a written response. ⋯ Those with > 1 year ICU work experience scored higher than those with less than 1 year. We conclude that the myriad of alarms that regularly occur in the ICU are too much for even experienced ICU staff to quickly discern. Patient and caregiver alike could benefit by a graded system in which only urgent problems have audible alarms, and these should be covered by regular in-service training.

Wide differing criteria are used to define the normal airway response to exercise, and as a consequence the estimated incidence of exercise-induced bronchospasm (EIB) in atopic children is wide. The purpose of this study was to establish normal range for changes in spirometry after exercise in children and then to use these normal values to assess the incidence of EIB in atopic children. ⋯ EIB should be defined by using more than one maximum expiratory flow-volume curve parameter (ie, FEV1 and FEF25-75). The EIB (defined as a fall in FEV1 and FEF25-75) was only seen in asthmatic children and not in other atopic groups.

We report the case of a woman treated with urokinase for acute pulmonary embolism with a right-sided heart thrombus. She developed life-threatening acute cor pulmonale which dramatically improved within 4 h with recombinant tissue plasminogen activator (rtPA). We emphasize the clinical interest of rtPA for the treatment of life-threatening pulmonary embolism.

Sleep deprivation and fragmentation occurring in the hospital setting may have a negative impact on the respiratory system by decreasing respiratory muscle function and ventilatory response to CO2. Sleep deprivation in a patient with respiratory failure may, therefore, impair recovery and weaning from mechanical ventilation. We postulate that light, sound, and interruption levels in a weaning unit are major factors resulting in sleep disorders and possibly circadian rhythm disruption. ⋯ The number of sound peaks greater than 80 decibels, which may result in sleep arousals, was especially high in the intensive and respiratory care areas, but did show a day-night rhythm in all settings. Patient interruptions tended to be erratic, leaving little time for condensed sleep. We conclude that the potential for environmentally induced sleep disruption is high in all areas, but especially high in the intensive and respiratory care areas where the negative consequences may be the most severe.
