test lung for ventilator

When lives are hanging in the balance, it’s imperative to know how to use a test lung for ventilator testing and calibration. Our lung simulators help to do that.

Because of its significance, we’ve outlined the testing applications of lung simulators, their benefits of use, and more: 

Why Do I Need To Test and Calibrate Ventilators?

Did you know that testing using Lung Simulators helps troubleshoot problems and verify proper operation of devices before they’re used on patients? 

No matter what, all ventilators must be tested and calibrated before they can be used on a patient. This is to avoid adverse side effects.  

Additionally, you must re-test and re-calibrate ventilators periodically to ensure they’re performing to established standards and manufacturer specifications. 

Testing ventilators also helps medical staff understand what to expect from the ventilators and how each mode, in particular, will perform under real-world conditions.

The 5+ Benefits of Simulation Over Traditional Learning

Saving lives is the most important thing in healthcare and emergency medical services. This is why huge advancements have been made in medical education, including simulation over traditional classroom learning. 

“In medicine, simulation offers good scope for training of interdisciplinary medical teams. The realistic scenarios and equipment allows for retraining and practice till one can master the procedure or skill… Teamwork training conducted in the simulated environment may offer an additive benefit to the traditional didactic instruction, enhance performance, and possibly also help reduce errors.” [1]

Below, we outline the top 6 benefits of simulation, and how it compares to traditional learning.

1. Bridges the Gap Between Training and Reality

Simulation improves both patient care and outcomes by providing more real-life scenarios for aspiring Respiratory Therapists and EMS Professionals. 

Practicing techniques and clinical skills, such as administering oxygen, is made easier with a simulation device that moves and “breathes” like a real human lung or lungs when ventilated. 

2. Simulation Ensures Patient Safety

Rather than practicing on live patients, simulation-based education ensures patient safety by allowing mistakes and the ability to correct them. 

Many lung simulators are simple at best, which isn’t ideal for real-life patient safety. By using a solid simulator that can mimic the realistic mechanics of the human pulmonary system (such as our Lung Simulators), medical students and professionals alike can perfect their skills without the burden of life vs. death hanging over their shoulders.

3. Safely Prepares for a Variety of Patient Scenarios

A simulation device should offer a range of calibrated lung compliance and airway resistance settings giving students and professionals an immersive, nearly hands-on experience. This allows the replication of hundreds of both healthy and diseased lung conditions, while providing accurate data to inform your testing, research and training. 

Our Lung Simulators are available in three models: Single Adult, Dual Adult and Adult-Infant. With three models for students and professionals to choose from, this allows for the ability to simulate a wider variety of patient sizes and health situations, thus improving techniques that will be used in real-life patient scenarios.

4. Reduced Errors in Training = Improved Patient Care

“To Err Is Human”, a report released by the Institute of Medicine (IOM) in 1999, revealed that medical errors result in a minimum of 44,000 and perhaps as many as 98,000 deaths per year in the United States. 

This landmark report called for improved training among medical students through a variety of ways, including simulation-based education. While the COVID-19 pandemic has forced universities and training centers to largely discontinue traditional classroom learning, simulation-based education has risen with its remote, digital education component.

5. Teaches Both Students and Professionals Communication Skills

The healthcare industry is moving towards a multidisciplinary team to deliver prime patient care. Therefore, possessing excellent communication skills is just as important as clinical skills for both Respiratory Therapists, EMS Professionals, and Surgeons alike. 

In particular, Respiratory Therapists are moving toward a patient-centered approach that can improve the management of diseases, such as Asthma, while also focusing on disease prevention and health promotion for patients.

6. Allows the Reassessment of Any Scenario to Identify Ways to Improve 

As mentioned above, simulation-based education allows for students to make mistakes (and correct them) without compromising a real-life patient’s health. 

Designed with our users’ needs in mind, our PneuView Software accurately provides numeric and graphical data from our Lung Simulator devices in real time. Additionally, you can save and export data for later review and analysis. This is especially useful for documentation of testing, or when access to certain ventilation technology is not always available.

When Every Compression Matters, You Can Rely on Michigan Instruments

Cardiopulmonary resuscitation, or CPR, is one of the primary factors that can influence the survival of a cardiac arrest patient. When proper, high-quality CPR is performed, it helps deliver oxygenated blood to the patient’s brain and other vital organs until medical care can be performed. This increases the patient’s chance of survival and reduces the risk of permanent neurological damage.

Manual CPR Fatigue Sets in Within 2 Minutes

Maintaining high quality, uninterrupted chest compressions is a key factor to increasing a patient’s chance of survival. However, a person performing manual CPR can become fatigued after performing just 2 minutes of chest compressions. Any deterioration in the depth or rate of compressions, or interruption to compressions caused by switching providers can impact the patient’s chances of survival. So, when every compression matters, you can rely on Michigan Instruments’ automated CPR devices to perform high-quality, continuous CPR.

What is High Quality CPR?

According to the American Heart Association (AHA), high-quality CPR must adhere to the following guidelines:

  • Chest compression fraction >80%
  • Compression rate of 100-120 per minute
  • Compression depth of at least 50mm (2 inches) in adults and at least 1/3 the AP dimensions of the chest in infants and children
  • No excessive ventilation
  • Minimal interruptions in chest compressions

Performing high-quality, manual CPR requires substantial physical and mental effort from the caregiver, especially depending on how long the resuscitation takes and how many times compressions must be interrupted. This can become even more challenging in a pre-hospital setting when a patient is being transported. Michigan Instruments’ automated CPR devices provide a solution that not only helps to reduce caregiver fatigue, but also provide non-stop, high-quality compressions that comply with AHA guidelines.

Rely on Michigan Instruments’ Life-Stat and Thumper Automated CPR Devices

At Michigan Instruments, we know that every compression matters. That is why our automated CPR devices, the Life-Stat and Thumper, provide consistent, external compressions that give the cardiac arrest patient their best chance at survival. Being lightweight and easy to use, our devices support a quick transition from manual to automated CPR that minimizes the interruption to compressions. With high-quality, hands-free CPR being performed, it gives medical professionals the time to concentrate on performing other life-saving care.

CPR saves lives. That is why Michigan Instruments has been a dedicated leader in the field of automated CPR for over 55 years. If you want to learn how our automated CPR devices have helped EMS professionals, doctors and nurses provide their patients with high quality CPR and care, contact us to learn more.
