Performance Specifications Specifications
2 - 2 0070-10-0691 Accutorr Plus Service Manual
2.1.1.1 Pulse Rate
Range: 35-245 BPM for Adult and Pediatric
70-245 BPM for Neonate
Display Resolution: 1 BPM
Accuracy: ±3 BPM or ±3%, whichever is greater
2.1.2 Maximum Cuff Pressure
Two means of limiting cuff pressure are provided: 1) a hardware over pressure monitor
that limits the pressure to 330 mmHg for Adults, 220 mmHg for Pediatrics, and 165mmHg
for Neonates; 2) a software overpressure monitor that vents if the pressure exceeds 300
mmHg for Adults, 200 mmHg for Pediatrics, and 157 mmHg for Neonates. If the
hardware over pressure circuit is tripped in normal operation, then the unit must be turned
off and on to reset the system.
2.1.3 Inflation Source
This inflation source is capable of supplying sufficient air to bring a volume of 700 cc’s to
a pressure of 300 mmHg in no more than 35 seconds. If the cuff is not inflated to the
desired pressure within 60 seconds, then the cuff is vented and a retry cycle is initiated.
2.1.4 Leak Rate
With the bleed valve closed, the maximum pressure drop is 10 mmHg in 90 seconds
measured with a 700 cc volume at a differential pressure of 250 mmHg.
2.1.5 Cuff Vent Rate
When the unit is vented, a volume of at least 700 cc’s is reduced from a pressure of 250
mmHg to a pressure of 20 mmHg in a maximum of 14 seconds.
2.1.6 Temperature (Predictive)
Range: 90-110°F, 32-43°C
Display Resolution: 0.1°F, 0.1°C
Accuracy: Meets ASTM E1112-2006 for accuracy
