What Are We Doing Here?

Since January, this site has had over 3,600 visits and almost 10,000 page views, average visit length is at 3:29. Thanks to everyone who's visited, and especially those of you who've called or emailed me with feedback, suggestions and corrections. Yes, even though I am a connectologist, I do make mistakes and I encourage everyone to keep me on the up and up. Take advantage of the comments link at the bottom of each post to share your knowledge and experience, your outrage, or provide corrections when I get things wrong. While compliments are always appreciated, it is the corrections that I think are the most important. Every comment left generates an email notification so I am sure to read every one, and will update any post accordingly. Comments can be either anonymous or you may identify yourself. Abusive comments will be deleted. Here's my corrections policy: any erroneous post will have an update at the bottom of the post noting the correction. The original error (unless its egregious) will remain so that a chronology is maintained that reflects changes over time. (Otherwise, I could just change the post and republish, but readers who had seen the post before the correction might be confused — and besides, I'm not pretending to be infallible.) Let me also encourage you to email me with news about your experiences, rumors, or other things concerning...

Vendor Problems with Connectivity: An Overview

Medical device vendors are like everyone else, they tend to resist change. It's rarely very pretty when technology and market requirements force a successful box company to add connectivity features. Over the years I've seen a range of outcomes and reactions, from denial (E for M cath lab recorders) to easy embrace (Sarns/3M). Fundamentally, connectivity is a transition from a homogeneous environment controlled by the manufacturer to a heterogeneous environment that feels completely out of control. When I started out some 20 odd years ago, connectivity meant a PC with some data analysis and reporting software plugged into the serial port on the back of device. Connectivity today means a bidirectional network connection that is wireless (unless it's a CT that's bolted to the floor). Now devices have to talk to (or interoperate with) third party systems that work within a general purpose IT network environment populated by other devices. None of this is rocket science, just an interrelated complex mess that benefits from specialized planning, process and expertise. Root causes for connectivity problems are based in human nature. First is the desire to apply current thinking and processes to new problems. If most things in life were intuitively obvious we would all be rich, driving flying cars or living in space colonies. Much about connectivity is not intuitively obvious. The next root cause is resistance to change. When a device...

Welch Allyn Introduces Propaq LT at AACN/NTI

As mentioned earlier, Welch Allyn introduced the Propaq LT at NTI earlier this week. Their sales force has been showing pre release demo units for the past few months. This unit continues the Propaq tradition of easy to use, rugged, transportable patient monitors. The Propaq LT is almost half the cost of the Propaq CS. At right, the Propaq LT (mounted in its self-charging cradle) is pictured with a Welch Allyn Micropaq (on the left) and a pen (for scale). It weights less than 2 pounds and is drop tested up to 75 g's, equal to a 6 foot drop on linoleum. Monitored parameters include 3 and 5 lead ECG, SpO2, respiration and NIBP for adult, pediatric and neonates. Battery life is similar to the Propaq, and because the bed rail cradle also charges the monitor it's always ready to go. The Propaq LT has some pretty interesting features. The small rugged monitor is ideal for monitoring in non traditional areas, in addition to EMT, transport, and procedure areas. This is the only multi parameter monitor that can be mounted on a regular IV pole. It also comes with an “opera purse” carrying handle for ambulating patients. The charging cradle has an integral bed rail hook. You can see that because the monitor is small, so is the screen. For situations where greater visibility is a requirement, they created a charging cradle that...
