CPREzy-Pad for external cardiac compression CPREzy-Mask Designed specifically for CPR CPREzy-Pad
The key to effective CPR chest compressions is a combination of achieving the correct rate, rhythm and depth compression. CPREzy-Pad assist's rescuers achieve these criteria by visually and audibly indicating the rate and depth at which CPR chest compressions should be performed.
An essential aspect of maintaining adequate blood flow to the vital organs during a cardiopulmonary arrest is the application of chest compressions at the correct rate. The human heart can beat at over 200 times per minute during strenuous exercise and at levels as low as 50 bpm when relaxed. During cardiac arrest, the UK Resuscitation Council, International Liaison Committee on Resuscitation (ILCOR) and the European Resuscitation Council all recommend that chest compressions be applied at a rate of 100 per minute for adult single rescuer CPR. CPREzy-Pad emits an audible tone at a constant 100bpm rate to indicate how often the chest needs to be compressed for optimal CPR. This audible tone is emitted at >80dB to ensure that it is heard above most ambient noise. CPREzy-Pad also contains a yellow LED which flashes in time with this 100bpm tone providing a visual cue for the rate of compression. This feature assists the application of CPR in cases where rescuers are hearing impaired, or are unable to hear the audible tone due to overwhelming aircraft or traffic noise. “It is an option to disable the tone and operate the CPREzy-Pad in silent mode – see below.”
When used correctly, CPREzy-Pad can reduce the risk of rib fractures, cartilage separation and coronary artery and cardiac conduction system damage. The rescuer achieves this risk reduction by applying only enough force to illuminate the LED that corresponds to the victim's approximate size. Rescuers should also be aware of an increased risk of chest injury when the caution light is illuminated during compressions. Note: Even during ideal application of CPR, chest injuries may occur. Rescuers should adjust their force accordingly in these situations. CPREzy-Pad can be used to assist individual's train for CPR emergencies. Using CPREzy-Pad allows external cardiac compression training to be performed with or without the use of resuscitation manikins. If a manikin is not available, CPREzy-Pad can simply be placed onto a flat surface and simulated cardiac compression can be performed and monitored by the CPREzy-Pad force sensing LED's. The audible tone emitted from CPREzy-Pad also assists rescuers to practice cardiac compressions at the optimal rate.
Research suggests that to maintain adequate blood flow to the vital organs, rescuers must fully release the applied pressure between chest compressions. This relaxation of pressure allows the heart to passively fill prior to the next chest compression. When using CPREzy-Pad, rescuers should ensure that none of the green LED's are illuminated during the upstroke of compression. This indicates that pressure has been released between compressions and is essential for the effective administration of CPR. When CPREzy-Pad is switched on, 3 tones will be heard. This is the automatic battery tester. 3 sharp tones means the battery is OK. 3 low tones and a flashing red light means the battery is low and should be replaced at the earliest opportunity. The battery must be replaced once a year or when indicated by the battery tester.
CPREzy-Pad is factory set to emit an audible tone at 100 beeps per minute (bpm), which is the ideal recommended rate for CPR chest compressions. This audible tone can be disabled and the unit will continue to function but in silence. To change the CPREzy-Pad from 100bpm to silence, hold the CPREzy-Pad 'on/off' button down for 5 seconds. After this period the CPREzy-Pad will go silent but the yellow rate indicator light will continue to flash at 100bpm. To reactivate the audible tone, at 100bpm, simply repeat the above procedure. In some cases, the administration of CPR can last upwards of 15 minutes. During this time rescuers can become fatigued and deliver sub-standard CPR. When CPR is performed manually, it is very difficult for rescuers to assess how much this fatigue is affecting their CPR performance. CPREzy-Pad assists rescuer fatigue in two ways. Firstly, rescuers often apply more force than is necessary during manual CPR which is not only dangerous for the patient, but also causes the rescuer to exert greater energy and fatigue at a faster rate. By indicating the appropriate compression force required CPREzy-Pad can reduce this rescuer fatigue. Secondly, CPREzy-Pad provides rescuers with instant feedback on their CPR application. When rescuers are unable to compress the chest at the rate and depth indicated by CPREzy-Pad, the rescuer is made aware of his approaching fatigue and can summon another rescuer to take over.
Properly performed CPR requires rescuers to have straight arms, interlocked fingers and their shoulders positioned directly over their hands. This ensures that each chest compression thrust is straight down on the sternum. CPREzy-Pad assists rescuers to apply this straight down force by evenly transferring the pressure through the CPREzy-Pad to the patient's chest. Applying force at an incorrect angle to CPREzy-Pad may cause it to tilt, which acts as a reminder to the rescuer to monitor and rectify his angle of compression. CPREzy-Pad also elevates the rescuers hands above the patient's chest, helping to prevent the fingers from resting on the ribcage and distorting the application of pressure. By indicating the correct rate and force required for each chest compression, CPREzy-Pad reduces the guesswork associated with performing effective CPR. CPREzy-Pad can assist anyone with a basic understanding of CPR to perform more effective chest compressions. Given that the majority of non-medical personnel will undertake only one CPR training course in their lifetime, CPREzy-Pad can help reduce the fear and guesswork that many rescuers will contend with when faced with trying to perform CPR chest compressions at the correct rate and force to save someone's life. CPREzy-Mask
Studies indicate the one of the greatest fears held by potential rescuers is that of contracting a disease or infection while performing mouth-to-mouth resuscitation. CPREzy-Mask provides a physical barrier between rescuer and patient so that no direct facial contact is required. The CPREzy-Mask one-way valve has very low air resistance, which reduces operator fatigue and is important for the victim's exhalation. The expiratory resistance in the valve for the victim is 0.6cm H2O/50L/min, and the resistance for the rescuer is 2.4cm H2O/50L/min. Both resistance values are low and fall well within the ISO and Australian requirements. CPREzy-Mask has a mouth tube that protrudes approximately 1cm into the patient's mouth. This feature helps keep the patients mouth open and directs the flow of expired air into the patient's mouth and lungs to optimise ventilation. This tube also promotes the appropriate positioning of the patients head for resuscitation. Proper head tilt and jaw thrust should be achieved to open the patient's airway and to allow the CPREzy-Mask mouth tube to be positioned between the patient's teeth.
CPREzy-Mask has a large diameter air tube that can be connected quickly and easily to emergency services oxygen equipment. To achieve this, the mouthpiece and valve assembly are detached from CPREzy-Mask, and the oxygen equipment (i.e. Air-viva bags etc.) are connected directly to the air tube. A large one-way valve provides abundant airflow and prevents the blowback of blood, vomit and mucous from the patient to the rescuer. Patient expired air is also vented out through the mask and away from the rescuer. After use on a patient, the one-way valve section can be detached and replaced with a new valve. CPREzy-Mask is designed for use with just one hand, freeing the other hand to feel for a pulse, hold a phone, or wave for further assistance. This feature distinguishes CPREzy-Mask from many existing CPR facemasks. Often, masks require the rescuer to move to the head of the patient and hold the facemask in position with both hands when giving rescue breaths. This procedure may become a considerable burden when single rescuer CPR is being performed. CPREzy-Mask saves valuable time by allowing the single rescuer to stay at the side of the patient to apply rescue breaths rather than moving to the head of the patient.
CPREzy-Mask is reusable after patient and manikin use. Clean CPREzy-Mask by soaking in a 1:50 solution of bleach for 10 minutes. CPREzy-Mask should not be pasteurised, boiled, gas or steam autoclaved. The one-way valve and mouthpiece can be cleaned and reused after use on a manikin, however, it is recommended that the one-way valve and mouthpiece be discarded after use on a patient. The one-way valve and mouthpiece is easily detached from CPREzy-Mask and can be purchased separately.

When
pressure is applied by hand to CPREzy-Pad, pressure sensitive light emitting diodes (LED's) indicate the correct amount
of force required for each chest compression. Four green LED's are present on
CPREzy-Pad to indicate the target pressure
required for patients of different weight and size. Rescuers need to estimate the size of the patient and apply
sufficient pressure to illuminate the corresponding LED. Applying this force in time with the audible tone ensures
consistent chest compression.
The mouth tube, valve assembly and top shell of
CPREzy-Mask are all composed of transparent polycarbonate to allow the victim's condition to be monitored whilst the mask is in position. Transparent components allow the rescuer to view any blood, vomit or change in patient lip colour. In the event that a patient vomits into the facemask this transparency also aids in the rapid removal of obstructions from the mouth tube.
