Intended Use

MAGLIFE C is intended for monitoring electrocardiogram (ECG), pulse oximetry (SpO2), pulse rate, partial carbon dioxide pressure at the end of expiration (EtCO2), nitrous oxide concentration (%N,O), partial pressure of inspired carbon dioxide (min inspired CO2), respiratory rate (RR), noninvasive blood pressure (NIBP), invasive blood pressure (IBP), concentration of gas inspired and expired (isoflurane, halothane, enflurane, desflurane, sevoflurane), and fraction of inspired oxygen (FiO2) in the immediate vicinity of Magnetic Resonance Imagers for the surveillance of patients undergoing MRI examinations.

Device Story

Maglife C is a multi-parameter patient monitor for use during MRI examinations. Inputs include ECG, SpO2, pulse rate, EtCO2, N2O, inspired CO2, respiratory rate, NIBP, IBP, anesthetic gases, and FiO2. System comprises a line-powered console (with battery backup) placed outside the magnet bore, connected to patient-side electrodes, transducers, cables, and tubes. Console enclosure acts as a Faraday cage to protect electronics from MRI interference. Non-metallic sensors and fiber optic signal transmission minimize burn risks and electromagnetic interference. Device provides real-time physiological surveillance to clinicians, enabling monitoring of patient status during MRI procedures. Benefits include safe patient monitoring within the MRI environment without degrading image quality or risking device movement due to magnetic attraction.

Clinical Evidence

Bench testing only. Validation included compliance with ANSI/AAMI standards (EC13, EC12, SP10, SP9, BP22, BP23, ES21) and IEC 601-1. MRI-specific testing verified performance at 1.5 Tesla, confirming no degradation of performance and no image artifacts when placed at least 60 cm from the magnet opening. Ferrous material content was verified to be sufficiently low to prevent movement due to magnetic attraction.

Technological Characteristics

Multi-parameter monitor; non-metallic sensors; fiber optic signal transmission; Faraday cage console enclosure. Complies with ANSI/AAMI EC13, EC12, SP10, SP9, BP22, BP23, ES21, and IEC 601-1. Line-powered with optional battery backup. Designed for 1.5T MRI compatibility.

Indications for Use

Indicated for monitoring ECG, SpO2, pulse rate, EtCO2, N2O, inspired CO2, respiratory rate, NIBP, IBP, anesthetic gas concentrations, and FiO2 in patients undergoing MRI examinations in the immediate vicinity of an MRI scanner.

Regulatory Classification

- Device Description 6.

MAGLIFE C is a multi-parameter patient monitor which has been designed for use in the immediate vicinity of a Magnetic Resonance Imagers for the surveillance of patients undergoing MRI examinations. The parameters that can be monitored are electrocardiogram (ECG), pulse oximetry (SpO2), pulse rate, partial carbon dioxide pressure at the end of expiration (EtCO2), nitrous oxide concentration (%N D), partial pressure of inspired carbon dioxide (min inspired CO2), respiratory rate (RR), noninvasive blood pressure (NIBP), invasive blood pressure (IBP), concentration of gas inspired and expired (isoflurane, halothane, enflurane, desflurane, sevoflurane), and fraction of inspired oxygen (FiO).

The monitor consists of a line-powered console (with optional back-up battery) which is placed outside the magnet bore, and appropriate electrodes, transducers, cables and tubes to allow the patient to be monitored during the examination. The console enclosure is a Faraday cage for the protection of sensitive electronic circuits.

- 7. Intended Use
MAGLIFE C is intended for monitoring electrocardiogram (ECG), pulse oximetry (SpO2), pulse rate, partial carbon dioxide pressure at the end of expiration (EtCO2), nitrous oxide concentration (%N,O), partial pressure of inspired carbon dioxide (min inspired CO2), respiratory rate (RR), noninvasive blood pressure (NIBP), invasive blood pressure (IBP), concentration of gas inspired and expired (isoflurane, halothane, enflurane, desflurane, sevoflurane), and fraction of inspired oxygen (FiO2) in the immediate vicinity of Magnetic Resonance Imagers for the surveillance of patients undergoing MRI examinations.

{3}------------------------------------------------

- Comparison of Technological Characteristics 8.
All four MRI compatible patient monitors employ established measurement methods combined with non-metallic sensors and fiber optic signal transmission to minimize the risk of burns and special shielding and filtering to minimize interference to and from the MRI unit.

- Nonclinical Tests Used in Determination of Substantial Equivalence 9.
The design of the Maglife C has been thoroughly validated at the unit and system level. Non-clinical tests were conducted to demonstrate compliance with the following standards:

- Cardiac Monitors, Heart Rate Meters, and Alarms. . ANSI/AAMI EC13 - 1992
- American National Standard for Pregelled ECG Disposable . Electrodes. ANSI/AAMI EC12 - 1991
- Electronic or Automated Sphygmomanometers. . ANSI/AAMI SP10
- . Nonautomated Sphygmomanometers. ANSI/AAMI SP9
- . Blood Pressure Transducers. ANSI/AAMI BP22 - 1994
- . American National Standard for Interchangeability for Resistive Bridge Type Blood Pressure Transducers. ANSI/AAMI BP23 - 1986
- . Safe Current Limits for Electromedical Apparatus ANSI/AAMI ES21 1993
- . IEC 601-1

{4}------------------------------------------------

Maglife C has been evaluated with respect to the recommendations for electrical testing included in the November 1993 Reviewer Guidance for Premarket Notification Submissions (Anesthesiology and Respiratory Devices Branch).

Tests were conducted in an MRI unit to determine the maximum field strength that Maglife C can withstand without degradation of performance and to verify that the amount of ferrous material in the Maglife C is sufficiently small so that movement of the unit due to magnetic attraction is not possible.

Tests were conducted to assess the effect of the Maglife C on the Homogeneity of the magnetic field inside the magnet bore. These tests, using a 1.5 Tesla MR unit, showed that the Maglife could be placed as close as 60 cm from the front of the opening from the magnet without causing any visible difference in the images.

- Conclusions From Nonclinical Testing 10.
The testing of the Maglife C demonstrates that the performance is substantially equivalent to predicate devices cited above.
