Inspire Obstructive Sleep Apnea Therapy Shows Promising Results

| January 14, 2014

Obstructive Sleep Apnea (OSA) affects approximately 12 million people in the U.S. alone. Repeated episodes of apnea due to airway collapse can lead to daytime fatigue and increase a person’s risk for more severe complications, usually cardiac. Existing therapies for OSA include upper airway surgeries, oral devices, and continuous positive airway pressure (CPAP). While CPAP can be particularly effective in patients when used, it can be cumbersome with many patients failing to comply with treatment.

Inspire Medical Systems (Maple Grove, MN), has developed an implantable OSA therapy called Inspire. The system is an implanted upper airway stimulator unit, that looks like a pacemaker, designed to stimulate the hypoglossal nerve on each breathing cycle to prevent airway obstruction during sleep. During implantation a stimulation electrode is placed on the hypoglossal nerve, a sensing lead is placed between intercostal muscles to sense breathing patterns, and a neurostimulator is implanted just below the clavicle bone. Patients activate the device at night using an external controller.

Zensorium Tinké, an iPhone Connected Pulse Oximeter (VIDEO)

| January 13, 2014

Zensorium, a Singapore-based startup was showing off at CES in Las Vegas its iPhone pulse oximeter called Tinké, that provides continuous blood oxygen level monitoring. Along with measuring oxygen levels, Tinké also tracks the heart rate, respiratory rate, and heart rate variability. The device, which weighs .4 oz (10.7g), works with a companion iOS app that displays the different cardiac metrics measured. The app displays a Vita index that is a fitness score computed from the user’s heart rate, blood oxygen level and respiratory rate. The app also displays a Zen score based on the heart rate variability data, and is a supposed measure of the user’s state of relaxation.

In order to use the Tinké , it is first connected to the dock connector of the iPhone. The user needs to wait untill a red light appears on the device, after which the user is required to place his or her thumb over the two holes on top of the unit and the reading is taken. The iOS app automatically registers and tracks daily readings and helps users track their cardiac metrics over an extended time.

iHealth Launches New Wristworn Pulse Oximeter, Ambulatory Heart and Blood Pressure Monitors at CES 2014

| January 13, 2014

iHealth (Mountain View,CA), a subsidiary of China-based Andon Health, launched a new wristworn pulse oximeter, an ambulatory heart monitor, and an ambulatory blood pressure monitor at CES 2014. The pulse oximeter continuously measures blood oxygen saturation (SpO2) and pulse rate at the finger tip, and is connected to a wrist strap that has an LED display showing the readings. The device also syncs via Bluetooth to the iHealth iOS app to display and track blood oxygen levels over time. Like other pulse oximeters, the device works by projecting two light beams, one red and the other infrared, onto the blood vessels in the finger. Oxygenated blood absorbs more infrared light and allows more red light to pass through, whereas deoxygenated blood absorbs more red light and allows more infrared light to pass through. A photodetector opposite the light emitters measures the ratio of red to infrared light received and from that calculates the amount of oxygen in the blood.

The second device unveiled by iHealth is an ambulatory heart rhythm monitor that is attached to the user’s chest using an adhesive patch. The monitor syncs with an iOS device using Bluetooth connectivity and displays a complete ECG on the user’s phone.
