The dispatcher will first instruct the bystander to place the phone on the floor next to the head/chest of the patient, as illustrated in Fig. 1, and to start chest compressions. The recorded video is fed through an algorithm extracting the main frequency of a repetitive ongoing motion in...
of Health clinical trials network database, the optimal combination of chest compression rate was 107 compressions per minute and chest compression depth of 4.7 cm; this finding remained relatively consistent regardless of age, sex, presenting cardiac rhythm, or cardiopulmonary resuscitation adjunct use....
Starting and stopping interventions such as positive pressure ventilation and external cardiac compressions are guided by heart rate, so a continuous display of heart rate during resuscitation is of clinical value [43,44]. Kamlin et al. [45] compared electrocardiograph (ECG) heart rate against the...
Also, ETCO2 is used to assess adequacy of chest compressions during resuscitation. NIRS monitoring is a noninvasive method of evaluating regional tissue oxygenation. NIRS sensors are generally placed over the abdomen or flank region and on the forehead. Trending NIRS values can detect fluctuations ...
HR was considered the most objective measure of a newborn infant’s condition and thresholds (60 and 100 bpm) became widely accepted indications for the commencement of interventions including respiratory support and cardiac compressions. Studies of HR assessment by auscultation and umbilical cord ...
After placement of an infrared capnometer between the endotracheal tube and resuscitation bag, an audiotape instructed the resuscitator to perform chest compressions at 100 per minute or 140 per minute for one minute, followed by another minute at the other rate. End-tidal carbon dioxide partial ...
The use of mechanical piston devices may be considered in specific settings where the delivery of high-quality manual compressions may be challenging for the provider (eg, limited availability of rescuers, prolonged CPR, in a moving ambulance, and in the angiography suite). What this study adds....
SS was comfortable to wear and easily monitored multiple participants from a distance. Conclusions: The Slate Safety wearable device demonstrated accuracy in measuring core temperature and heart rate while not restricting the motion of the worker, and provided a remote monitoring platform for ...
Out-of-hospital cardiac arrest (OHCA) is a challenge for medical staff, especially in the COVID-19 period. The COVID-19 disease caused by the SARS-CoV-2 coronavirus is highly infectious, thus requiring additional measures during cardiopulmonary resuscitation (CPR). Since CPR is a highly aerosol...
Dolby and DTS are lossy audio compressions which are often used for this purpose as they’re capable of reducing PCM audio file sizes by as much as 90%. Unfortunately, the way that Dolby and DTS encode PCM channels into a bitstream for storage and then decode it back for playback is not...
