Understanding the Role of Inertia in Mechanical Test Lungs

It’s no secret—mechanical systems move differently than biological systems particularly when it comes to inertia.  This concept has a number of significant implications when working with a mechanical test lung.  During ventilation the inertia of the lung chamber must first be overcome before it can start to expand.  Prior to this point any gas delivered to the lung has been delivered into a chamber with static compliance.  Only when the lung chamber begins to...

4 Do’s and 2 Don’ts of Mechanical CPR

Mechanical CPR devices are becoming more common in EMS, fire departments, and hospital emergency rooms.  With the rise in popularity of this technology it is important that both providers and even bystanders understand what these devices are and how they work.  While it only covers the basics, following this list of do’s and don’ts will help you understand mechanical CPR a bit better.  In the case of a cardiac arrest where a Mechanical CPR device is...

Simulating a Pneumothorax on a Dual Adult Lung

A number of our customers have been requesting information on how to simulate a pneumothorax using the Michigan Instruments Training and Test Lung (TTL).  The following will describe how this condition can be simulated on a TTL, using setup options offered by this device.  The principles described can be applied to many laboratory situations that do not require the use of this lung. A pneumothorax is usually characterized in humans by a collection of gas or fluid between a lung and...

Meet Julia

  Cardiac arrest is the leading cause of death in America, but it is an event that is survivable.  Last week I had the pleasure of going down to Greensboro North Carolina to talk with Julia Sims and her family about her true, complete recovery.    Julia Sims has experienced a perfect day.  On March 19, 2011 she suffered a massive cardiac arrest, months in the making. It came as a complete surprise even after an EKG/Stress test and a professional cardiologist...

6 Steps to a Quick, Painless FDA Audit

So you’re in the medical device business and going about your normal routine when the phone rings. On the other end is an FDA inspector announcing their intent to conduct a surveillance audit of your facility. As you hang up the phone you’re bound to be a little edgy—this can be a lengthy, frustrating process especially if your documents are not in order.  Fortunately there are plenty of steps that can be taken to make sure that these procedures go as quickly and as...

Military vs. Medical: Five Things Private Simulation Labs Need

It is no secret that military spending has gone down since sequestration (and other spending cuts), and one of the areas to take a major hit from this was in simulation.  I remember attending the International Meeting on Simulation in Healthcare at the San Diego Convention Center about a year and a half ago.  The sounds of my automated ventilator were constantly drowned out by faux gunfire and helicopter blades.  Half of the people that walked by my booth were in uniform. ...

International Search Engines and Optimization

Whenever search engines are mentioned Google is probably the first thing that comes to mind.  It is one of the largest, most widely used engines in North America and is a staple in many of our lives.  When building a website a company or individual should consider how their pages will appear to Google (as well as other search engines such as Yahoo and Bing) in order to get the largest possible visitor base.  The optimization of this appearance has been a growing industry over...

CAPA Part 1—Introduction

All problems in the professional world have a financial impact on the companies associated with them. For this reason many procedures have been developed to troubleshoot and identify potential problems within a business.  One tool that is often used to help ensure efficiency is a formal Corrective and Preventive Actions (CAPA) program. Formal CAPA programs allow the companies that implement them the ability to monitor and maintain their quality system.  It is for these reasons...

The Confusing Process of International Regulation

For many, the process of gaining regulatory approval can be long and confusing, especially if that approval is sought overseas.  While this is not always an easy process there are a few things that you should remember whenever you are attempting to get your products approved in a new country.    ISO, or the International Organization of Standardization, is the primary supplier of international regulatory standards, but compliance with ISO standards does not guarantee...

High Frequency Oscillatory Ventilation-Part One

Acute Respiratory Distress Syndrome, or ARDS, is by no means a new condition in the respiratory care industry, but there are certainly some new treatments being tested to help treat it.  Herneations, H1N1, SARS and many other conditions are all forms of ARDS, and it can affect patient of almost any age.  High frequency oscillatory ventilation (or HFOV) is an innovative form of respiratory care that, in America, is not widely used or understood.  Fortunately, the concept is...

High Frequency Oscillatory Ventilation-Part Two

Due to difficulties in assessing the outputs (from the patient’s perspective) of HFOV ventilators many analysts have resorted to monitoring pressure outputs; the theory being that so long as an adequate FIO2 (fraction of inspired oxygen) reaches the patient and the pressures remain safe, the ventilation is a success.  Unfortunately this method does little to help us understand HFOV on a deeper level, and without this understanding it is difficult to know how the science and practice...

High Frequency Oscillatory Ventilation Part 3 of 3

In HFOV tidal volume and LPM (flow) values can be exceptionally difficult to monitor.  Several third party devices have been developed to monitor this, but due to a lack of any solid standard of operation it is still considered to increase patient risk over conventional ventilation.  Currently, HFOV has found a niche in non-conventional settings, primarily in the treatments of neonatal patients and some adult cases where the patient is considered to be past the point at which...

Modern Marketing: Why the Trade Show

The arrival of web based marketing techniques has made the marketing industry considerably more competitive.  Many companies have begun to question the high costs of trade shows when the same money could be spent online to get the products in front of tens of thousands of fresh eyes, all without the added expense of travel.  I don’t think that anyone is going to deny the benefits of a web based inbound marketing technique, but let’s not forget that trade shows are also...
