What is the CPR machine? 

You might already be familiar with the manual CPR process. A CPR machine does exactly that but in a mechanical manner. Mechanical cardiopulmonary resuscitation devices are designed to give a patient automated chest compression. Just like regular CPR, mechanical CPR devices focus on resuming spontaneous circulation. The biggest plus that these machines provide is that they are highly accurate. The manual CPR process can be influenced by many factors, for example, fatigue and fear. But since these devices aren’t affected by such factors, they provide incredibly high-quality CPR. No wonder these machines are now an essential element of primary healthcare facilities. 

The types of CPR machine

Courtesy of the advancements in the medical device industry in recent times, different types of CPR machines are available today. Let us talk about them in the following lines.

1. CPR defibrillator

An automated external defibrillator is a portable electronic device. It can automatically diagnose life-threatening cardiac arrhythmias of ventricular fibrillation and pulseless ventricular tachycardia. How does this device help the patient? Well, it does so by applying electricity. This application of electricity serves as a stop plug for arrhythmias. As a result, the normal effective rhythm of the heart is restored. 

2. Lucas CPR

Lund University Cardiopulmonary Assist System (LUCAS) device is considered one of the perfect alternatives to the manual PCR machine. It is considered so because it can provide consistent compressions at a fixed rate, even if the patient is transported in a complicated transport setup. It negates any physical strain on patients going through an emergency phase. The earlier model of the LUCAS CPR machine was a pneumatic one, while the more recent releases feature a battery-operated version.

3. Automatic CPR

Automated. Portable. Battery powered. These three adjectives define the Automatic CPR machine or AutoPulse very well. It is a device created by Revivant but later bought and is now manufactured by ZOLL Medical Corporation. Coming towards the device architecture consists of a constricting band and half backboard. The machine uses distributing bands to deliver chest compressions. Another term for these compressions is LBD-CPR. Here, LBD stands for load-distributing band CPR. 

What are the uses of CPR machines? 

Now, let us have a look at certain beneficial features of CPR machines in the following lines: 

1- They provide better access to the patient. 

2- Manual CPR often requires paramedics to exert beyond their capacity. Automated CPR machines have nullified that requirement. 

3- Even though it is minimal, there is always a risk of patients getting injured during manual CPR. Mechanical CPR machines save the day in that regard as well. 

4- Caregivers don’t suffer from fatigue if mechanical CPR is administered to the patient in an emergency. 

5- The hospital applications of CPR given by a medical device are more than just one. For example, these devices are a must for in-hospital cardiac arrest, emergency departments, coronary units, intensive care units, and even organ transplant facilities. 

How does a CPR machine work? 

Let us take the example of the LUCAS CPR machine to understand the basic principles of a CPR machine. The LUCAS CPR machine is an example of a piston device. It features a mechanism for active chest recoil. There are two parts to the LUCAS CPR machine. These are a backplate and a piston mechanism. Together, they are linked in such a manner that they encircle the patient. The LUCAS CPR machine delivers compressions at 102 per minute. The depth is 5.3 cm. However, this number can vary, depending upon a patient’s sternal height. The most significant benefit of using such a device is that it consistently delivers highly high-quality chest compression. Eventually, this improves the intra-arrest hemodynamic profiles. 

Working modes of CPR machines

Again, let us use the example of the LUCAS CPR machine. It is available in two different modes. These are active continuous and active 30:2. As it is understandable from the name, the active continuous mode delivers continuous compressions. Watch out for the green LED signal that will blink at least ten times per minute. This blinking will serve as an alert for ventilation during an ongoing compression.

On the other hand, things are slightly different in the case of LUCAS active 30:2. In this mode, the CPR machine delivers 30 chest compressions, then stops for three seconds. This mini-stop allows the operator to perform two ventilations. Once the stop is over, the cycle starts again. The operator is alerted before every ventilation phase by an intermittent LED signal combined with an audible sequence. 

The risks of CPR machine

While mechanical chest compression devices are proving to be a real game changer, there are certain complications that have been reported with them. The most reported complications of this therapy are skeletal and skin injuries. However, the more severe or life-threatening injuries are a rarity.

Main specifications of CPR machines

Now, let us look at the key parameters that define a CPR machine’s working. These numbers are standardized for the sake of keeping the whole operation optimal. 

1. Compression frequency

This number tells us how many compressions will be performed per minute. Usually, this number is around 100-120 compressions per minute. 

2. Compression depth

How deep should your CPR application be? Compression depth gives us that number. Typically, it is between 2-2.5 inches. 

3. Compression-to-breath ratio

Compressions are given in sync with rescue breaths. A ratio is a standard number that achieves the objective of CPR very well. Thirty reductions against two rescue breaths are an ideal number. 

4. Compression to relaxation time ratio

Again, like all the other numbers we have described, this ratio is also fixed. The compressions should be provided at 80-100 per minute with a 1:1 compression-to-relaxation balance.

The best prices of CPR machines online

This state of MWCPR-1A Auto CPR machine is currently available for a price tag of $9,191.76 per set. 

This is yet another fine MWCPR-1B Auto CPR device currently available for a price tag of $8,012.72 per set. 

The price for this CPR machine might be on the higher side, with a price tag of $16,261.24 per set, but it has all the hallmark features of a quality CPR machine. 

Conclusion

Besides having a good and highly skilled team in your cardiac facility, such a setting must have the best CPR machines that should serve the common purposes mentioned earlier in this brief. These CPR machines will not only save a patient but also the day for your clinic. And to purchase premium quality CPR machines,

FAQ

Before we sign off, let us answer some of the most frequently asked questions about CPR machines in this section. 

1. What is CPR?

CPR stands for cardiopulmonary resuscitation. An emergency procedure can save a person’s life when their breathing or heart stops functioning. This phase is called cardiac arrest, and the heart cannot pump blood to the rest of the body during this phase. CPR is the standard procedure to save someone’s life during this phase. 

2. What are the methods used in CPR?

There are two most commonly performed CPR methods. First, there is conventional CPR, which uses chest compressions and mouth-to-mouth breathing. When applied together, the ratio is 30:2 compressions to breath.  

3. What are the functions of CPR machines?

They provide better access to the patient, minimize the risk of injury to the patient, ensure caregivers don’t suffer from fatigue, and are considered a must for in-hospital cardiac arrest, emergency departments, coronary units, intensive care units, and even organ transplant facilities.
