iPhone becomes an accurate, touch-free heart rate monitor with Cardiio


We have covered a couple of iPhone apps here on auscultate but perhaps none of them as robust or as interesting as Cardiio. And while there seems to be no end to new Apps or mobile ways to check your heart rate, none seem to be as clever as Cardiio. Quite simply you download the app, point it at your face, and it provides you with an accurate heart rate. How, you ask?

Cardiio uses your phone’s front camera to analyze the amount of light reflected off of your face; it accurately measures your pulse without any extra hardware. Seriously, just hold your phone and look straight into the camera to get your reading. Then check out the dashboard to see how it changes over time.

I am a skeptic by nature and I have seen enough apps under-deliver. Before testing Cardiio I simply had a hard time believing what they said was true. So to offer up a litmus test I took my own pulse with my Philips Viridia 24C before testing the app. Surprisingly enough, the results were the same. Cardiio read my heart rate by watching the light reflected on my face. Once the measurement was accurate and consistent it displayed on the iPhone screen. I even had the option to save it for future reference.

One of the more amusing parts of the app is that I was then able to see how healthy my heart rate was and compare it to the rest of the country.

In short, that is pretty much all the app does. But for $4.99 it’s pretty awesome that you can get an accurate heart rate and fitness level just from a facial reading.


• Touch-free, real-time heart rate measurements
• Beautiful and easy to use interface
• Personal dashboard with history (daily, weekly and monthly)
• Fitness level rating based on your heart rate
• Estimate your potential life expectancy
• See how your heart rate stacks up to others



Reusable Temperature Sensor for GE Marquette


Temperature measurement, a vital part of most industrial operations, is typically accomplished by a temperature sensor–a thermocouple or a resistance temperature detector (RTD)–in contact with a solid surface or immersed in a fluid. Several factors must be considered though when selecting the type of sensor to be used in a specific application: temperature range, accuracy, response time, stability, linearity, and sensitivity. In this video we’ll take a look at the reusable temperature sensor made for the GE Marquette patient monitor.

Managing high blood pressure is something that effects nearly 1/3 of adult Americans. The American Heart Association and other organizations recommend anyone who has high blood pressure monitor his or her blood pressure at home. Home monitoring can help you keep tabs on your blood pressure in a familiar setting, make certain your medication is working, and alert you and your doctors to potential health complications. It is easy to do actually with the right equipment and an understanding of your equipments operating parameters.

GE Healthcare Marquette Direct Connect, One-Piece ECG Cable


Auscultate, the blog built for the love of patient monitoring, reviews the GE Healthcare Marquette Direct Connect, One-Piece ECG Cable.

If you’re considering the GE Healthcare Marquette Direct Connect, One-Piece ECG Cable for your patient monitor needs than you more than likely already know and fully understand the importance of the ECG in healthcare. It the most commonly performed cardiac test! Whey? Because  the test is simple to perform, risk-free and inexpensive.

From the ECG tracing, the following information can be determined:

  • the heart rate
  • the heart rhythm
  • whether there are “conduction abnormalities” (abnormalities in how the electrical impulse spreads across the heart)
  • whether there has been a prior heart attack
  • whether there may be coronary artery disease
  • whether the heart muscle has become abnormally thickened

Because all of the above are so vital to healthcare and patient management it is important to have the right equipment for the job and the GE Healthcare Marquette Direct Connect, One-Piece ECG Cable is just that.

How healthcare law may be effecting patient monitoring


Over 35 million patients are admitted each year into United States hospitals. Nearly 120 million visit hospital emergency rooms each year. In addition, outpatient visits (including lab work, imaging, and rehabilitation visits) number near 481 million. And if that weren’t enough of a strain, there is then on average 4 million babies born in hospitals each year. These sorts of statistics require a significant amount of hospital resources in regards to staff and beds and because of such leave a number of hospitals over worked and seemingly subpar in delivery. The question now has become how will new healthcare laws effect the already overstressed healthcare facilities?

One non-conventional and unique way some patients are easing the burden on hospitals is to monitor their own vital signs and health rates. Likewise, hospitals are turning to more efficient and effective monitoring devices.

Between 2007 and 2011 Kalorama Information Reports indicate a growth in development and facilitation of remote and wireless patient monitoring systems. Continue Reading →

GE Marquette Sp02 sensors reviewed by Auscultate


Auscultate, the blog built for the love of patient monitoring, reviews the SpO2 accessories for the Marquette Solar 8000. We review the adult and pediatric (both hard clip and soft boot), neonate and multi-site. Do you have this monitor? How do your SpO2 accessories work? Tell us what you think by leaving a comment!

Marquette Solar 8000 review


Even though a bit dated looking the Marquette Solar 8000 continues to push the envelope in monitoring sophistication. Its exceptional range of advanced solutions helps clinicians cost-effectively improve the care process in demanding environments throughout the healthcare enterprise.

Interfaces enhance versatility and value. Because it interfaces to over 70 devices, the Solar 8000 is your single, convenient reference point for efficient patient assessment.

I am pleased to review it today using just a standard DELL monitor and the basic equipment of the Marquette system.

Philips Viridia Universal NIBP Cuff review


Judging by the huge numbers of high blood pressure medications being prescribed today – especially to older adults – high blood pressure seems to have reached epidemic proportions.

Measuring a patients blood pressure and keeping a record of the measurements is more important than ever. The measurements can be used to prescribe essential medicines and work to control potentially high blood pressure. But like with all medical practices the right equipment is key!

Free Wi-Fi in your hospital room


As reported by the Wall Street Journal on May 25, 2012 hospitals are preparing to sever the cord; the cat 5e that is. Well, not really. In fact, it is a wireless system almost unseen to date!

In place of knots of wires stuck to patients to monitor their blood pressure, heart rate, oxygen level and body temperature, doctors and the companies that supply them hope to use Band-Aid-like sensors to accomplish the same task wirelessly.

The Federal Communications Commission is expected to vote Thursday to open up spectrum for wireless medical devices, raising the possibility of easier hospital-patient monitoring, fewer tubes in emergency rooms, and more remote monitoring at home.

The shift will make it easier to track patients’ conditions, improving the odds that health problems will be caught before they become an emergency, analysts and clinicians say. Continue Reading →

Philips M1190A SpO2 Sensor review


Pulse oximetry has come a long way since 1935 when Karl Matthes developed the first 2-wavelength ear O2 saturation meter with red and green filters. In later years those two were switched to red and infrared filters. In todays medical facilities we are more accustomed to seeing those infrared sensors being placed on a thin part of the patient’s body, usually a fingertip or earlobe, or in the case of an infant, across a foot in order for the light of two different wavelengths to pass through the patient to a photodetector.

At that point the changing absorbance at each of the wavelengths is measured, allowing determination of the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) nail polish.

It is key then to have a reliable Sp02 sensor such as the Philips M1190A.
