Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available. 
 Which is the apt title for the abstract? option1: Refibrillation managed by EMT-Ds option2: Maintenance of compliance in a small diameter arterial prosthesis.
Solution: Refibrillation managed by EMT-Ds
Why? The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.

New input: Abstract: Previous resistive load detection (RLD) studies have ignored the nose, the usual route of breathing. Weber's law predicts the delta R50 (the added load detectable on 50% of presentations) to be a fixed percent of the background resistance (R0) and thus the delta R50/R0 ratio (the Weber fraction) is constant. We have noted the nose to be sensitive to added load, we wondered if the nose might play a role in RLD. To determine whether this was true and to characterize the effects of changes in R0 in the range of normal nasal resistance (RN), we determined R0 and delta R50 using standard techniques under the following conditions: nose vs. decongested nose, nose vs. nose with added external R0 (3.0 and 8.0 cmH2O X l-1 X s), nose vs. anesthetized nose, nose vs. mouth, and mouth vs. mouth with added load (3 cmH2O X l-1 X s). We found that decongestant decreased RN [4.3 +/- 0.6 (SE) to 3.1 +/- 0.5 cmH2O X l-1 X s, P less than 0.05] and delta R50 (1.7 +/- 0.5 to 1.1 +/- 0.3 cmH2O X l-1 X s, P less than 0.05). When an external load of 3 cmH2O X l-1 X s was added to the nose, delta R50 did not change significantly (1.4 +/- 0.2 to 1.1 +/- 0.2 cmH2O X l-1 X s), but the Weber fraction decreased (0.28 +/- 0.05 to 0.15 +/- 0.03, P less than 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
