DR181 Holter Recorder

The DR181 Holter recorder was designed with the following three goals in mind: ease-of-use for the patient and clinician, accuracy of the data and durability of the unit.  It does it all from 3-channel Holter, to OxyHolter, and in a 12-lead configuration, provides a high quality research and clinical evaluation tool

Description

Large soft-keys, easy to read multi-line LCD and many foreign language options are among the features that distinguish the DR181 Holter Recorder. Extra battery capacity makes it ideal for long Holter studies of up to 72 hours (lithium batteries). Use either a 5- or 7-lead patient cable with the 3-channel configuration.

The DR181 recorder prevents identification mix-ups by storing Patient ID on removable media and units may be rapidly redeployed to the next patient while patient data is analyzed from the removable media.

Applications

• Up to 72-hour Holter Monitoring
• 12-Lead ECG option available
• OxyHolter / Sleep Apnea function with OxyHolter cable

Features

3-Channel Holter: 5-, 7- or 12- lead
12-lead / 9 Holter: No short-cuts!

This 12-lead system does not use arithmetically derived or reconstructed data from non-standard Holter lead hook-ups.

OxyHolter® Recorder: Quickly isolate (or correlate) cardiac and pulmonary issues. With synchronized sets of data — one set of cardiac data (standard Holter) and one set of pulmonary data (saturated O2 levels via pulse oximetry) conveniently obtained via the DR181 and NorthEast Monitoring’s proprietary OxyHolter® cable.

Availability

• Support and updates included under Warranty
• Extended Warranty and support available

A New Approach for Evaluation and Management of Cardiopulmonary Diseases

Apnea: Manage O2 therapy and screen for sleep disorders. Twenty-four hours of SpO2 data correlated with 1 or 2 channels of cardiac data and optional airflow allow quantitative observations (value and trend) of response to O2 variations.

Proprietary tool removes artifact from HR and O2 data.

OxyHolter® can be used with a Holter-only cable (3CH of ECG), an OxyHolter cable (2 CH ECG, 1CH of mux’d beat and SpO2) or an OxyHolter®/A cable (1 CH ECG, 1CH mux’d beat and SpO2 and 1CH directly measured airflow). DME’s can use OxyHolter® to substantiate or “fine tune” beneficiary’s oxygen requirements. With an accurate tool like OxyHolter®, O2 levels are optimized to determine replenishment schedules. The savings derived drop directly to the “bottom line” of a DME provider and quickly provide an ROI for OxyHolter.

OxyHolter® is designed with the following goals in mind:
1) Ease-of-use – easy hookups, large LCD screen, big buttons, several language options
2) Accuracy of data – 95%+ sensitivity and specificity for OSA when compared to full PSG
3) Low cost of consumables – less than $4 / patient OxyHolter® and $5 / patient OxyHolter

The DR181 in a 12-lead configuration provides a high quality research and clinical evaluation tool. It records 12-lead / 9 channels of data – no short-cuts! Our 12-lead system does not use arithmetically derived or reconstructed data from non-standard Holter lead hook-ups. These short-cut methods may capture accurate data for normal beats, but the picture degrades sharply for virtually all morphologies of interest. The DR181 12-lead settings can be adjusted to fit your 12-lead recording requirements. Intervals and strip lengths are adjustable, and you can also choose to record continuously in all 12-leads at a resolution of 12 bits per sample.
