== Background and Identification ==

=== Overview ===

The Nellcor™ Bedside Respiratory Patient Monitoring System is a portable pulse oximeter intended for prescription use only as a continuous non-invasive monitor of arterial oxygen saturation (SpO2) and pulse rate of adult, pediatric, and neonatal patients during both no motion and motion conditions, and for patients who are well or poorly perfused(Covidien,2013) The monitoring system is intended for use in hospitals, hospital-type facilities, and during intra-hospital transport is intended only for facility-use care of adults to find patterns of desaturation indicative of repetitive reductions in airflow through the upper airway and into the lungs. It is also specified for the treatment of respiratory failure and helps assist patients in spontaneously breathing. I would be providing good repair guides that would help clinicians troubleshoot any unforeseen problem that may occur in this device.

=== Features ===

* Provides three breathing modes, including Continuous Positive Airway Pressure (CPAP), Inspiratory/Expiratory Positive Airway Pressure (I/E PAP), and Assist Control (A/C).
* Monitors pressure, tidal volume, respiratory rate, ait leaks, peak flow, and I: E ratio.
* Provides precise respiratory support and patient comfort via adjustable inspiratory and expiratory trigger sensitivity.
* Uses audible and visual indicators to alert users to power failure, system leaks, and other conditions that could affect device performance.
* Allows a maximum pressure setting of 30 cm with a pressure limitation of 40 cm for a single fault condition.
