Article Synopsis
- The study compares the effectiveness of finger- and forehead-derived respiration-induced pulse amplitude variation (PAV) against arterial blood pressure-derived pulse pressure variation (PPV) for predicting fluid responsiveness in patients undergoing major surgery.
- Data was collected from 29 patients, revealing that finger-derived PAV showed better agreement with ABP-derived PPV (3.2% agreement) compared to forehead-derived PAV (12.0% agreement).
- Baseline variation was identified as a significant confounding factor affecting the agreement between PPV and PAV, and after adjustment, both PAV measurements showed improved agreement, with finger PAV performing generally better than forehead PAV.
Article Synopsis
- The study investigates how arterial pulse pressure variation (PPV) algorithms predict fluid responsiveness during surgery, especially when blood pressure changes rapidly.* -
- It records blood pressure data from 23 patients undergoing major abdominal surgery to assess different PPV algorithms.* -
- Findings indicate that while all algorithms work well under stable conditions, additional processing steps enhance the reliability of PPV measurements throughout surgical procedures.*
Detecting return of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR) is challenging, time consuming, and requires interrupting chest compressions. Based on automated-CPR porcine data, we have developed an algorithm to support ROSC detection, which detects cardiogenic output during chest compressions via a photoplethysmography (PPG) signal. The algorithm can detect palpable and impalpable spontaneous pulses.

We investigated the potential of photoplethysmography (PPG) to detect the presence of a spontaneous pulse during automated CPR in an animal study.
Methods: Twelve anesthetized pigs were instrumented to monitor circulatory and respiratory parameters.
