Device Facts

• Record ID: K972829
• Device Name: CRICKET 2000 RECORDING PULSE OXIMETER
• Applicant: Respironics, Inc.
• Product Code: DQA · Cardiovascular
• Decision Date: Oct 28, 1997
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 870.2700
• Device Class: Class 2

Indications for Use

The Cricket 2000 is a recording pulse oximeter which measures functional blood oxygen saturation, pulse rate/interval and finger movement. Because of SpO2 and pulse rate alarm limits that can be set by the operator, it can be used for continuous monitoring. It also interfaces with a commercially available computer. The pulse oximetry, raw infrared and red waveform data, as well as the pulse rate data, can be viewed real-time on the computer using custom Windows -based software that is provided with the pulse oximeter. The software also enables the user to do some data analysis, which can be used to draw meaningful implications during sleep apnea analysis studies. The Cricket 2000 is primarily indicated for use with patients suspected of suffering from, or with potential to suffer from, episodes of hypoxemia. The Cricket 2000 is intended for patients weighing more than 30 kg in both the hospital/institutional environment (supervised) and the home (unsupervised) environment.

Device Story

Cricket 2000 is a recording pulse oximeter measuring functional blood oxygen saturation (SpO2), pulse rate/interval, and finger movement. Device inputs include infrared and red light signals; transforms these into real-time waveform and pulse rate data. Output is displayed on a connected computer via custom Windows-based software. Used in hospital or home settings by clinicians or patients for continuous monitoring and sleep apnea analysis. Software enables data analysis to assist clinical decision-making regarding hypoxemia episodes. Benefits include continuous patient monitoring and diagnostic support for sleep-related breathing disorders.

Technological Characteristics

Recording pulse oximeter; measures SpO2, pulse rate, and finger movement via infrared/red light sensors. Interfaces with external computer. Software-based data processing and visualization. Intended for patients >30 kg.

Indications for Use

Indicated for patients weighing >30 kg suspected of or at risk for hypoxemia. Used for continuous monitoring of SpO2, pulse rate, and finger movement in hospital/institutional (supervised) or home (unsupervised) settings.

Regulatory Classification

Identification

An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter.

Predicate Devices

#### 510(K) Summary . Cricket 2000 Pulse Oximeter 10/23/97

## Reason for 510(k):

Modification to existing device, primarily replacing the DOS-based software with the Windows-based User Interface Software.

## Device Description/ Intended Use/Indications for Use/Pationt Population:

The Cricket 2000 is a recording pulse oximeter which measures functional blood oxygen saturation, pulse rate/interval and finger movement. Because of Sp()2 and pulse rate alarm limits that can be set by the opcrator, it can be used for continuous monitoring. It also interfaces with a commercially available computer. The pulse oximerry, raw infrared and red waveform data, as well as the pulse rate data, can be viewed real-time on the computer using custom Windows -based software that is provided with the pulse oximeter. The software also enables the user to do some data analysis, which can be used to draw meaningful implications during sleep apnea analysis studies.
