Introduction
Introduction Description The Bravo® pH Monitoring System is intended to be used for gastroesophageal pH measurement and monitoring of gastric reflux: •
First, a Bravo pH capsule is calibrated and the receiver (an ambulatory, programmable data recorder) is prepared.
•
Using the delivery device, the capsule is positioned and attached in the patient’s esophagus, following either endoscopy or manometry.
•
The data is collected by the capsule and transmitted to the Bravo pH receiver for the duration of the study.
•
The data is then uploaded from the receiver to the software workstation. The software is intended to record, store, view, and analyze gastroesophageal pH data, enabling physicians to interpret study results.
Refer to the Bravo pH Capsule with Delivery Device insert sheet for indications, contraindications, warnings, and precautions. Warning: Patients are restricted from undergoing an MRI study for 30 days from the start of a pH study. The Bravo pH Monitoring System is not compatible for use in an MRI magnetic field. Use of the Bravo pH Monitoring System in an MRI magnetic field will result in damage to the system and possible patient injury.
Indications for Use The Bravo pH Monitoring System is intended to be used for gastroesophageal pH measurement and monitoring of gastric reflux. The Bravo pH capsule can be attached following either endoscopy or manometry.
Contraindications Patients with bleeding diathesis, strictures, severe esophagitis, varices, obstructions, pacemakers or implantable cardiac defibrillators are contraindicated.
Warnings and Precautions •
Bravo pH capsule with delivery device: Potential complications include, but are not limited to: • tears in the mucosal and submucosal layers of the esophagus causing bleeding and requiring possible medical intervention • perforation
•
gastrointestinal endoscopy: Potential complications include, but are not limited to: perforation, hemorrhage, aspiration, fever, infection, hypertension, respiratory arrest, cardiac arrhythmia or arrest

Introduction • nasal intubation: Potential complications include, but are not limited to: sore throat, discomfort, and nasopharyngeal damage resulting in bleeding and soft tissue damage •
Bravo pH capsule: Potential complications include, but are not limited to: • discomfort associated with the capsule, or failure to detach from the esophagus within several days after placement, either of which may necessitate endoscopic removal • premature detachment of the capsule
•
The safety and efficacy of the Bravo pH capsule with delivery device has not been established for pediatric use.
•
The Bravo pH capsule with delivery device is a single-use, disposable device. Reuse or any other misuse of a Bravo pH capsule with delivery device (such as sharp bending or kinking) will result in an increased potential for damage to the delivery device and capsule, and possible patient injury.
•
Prior to use, all equipment for the pH study should be examined carefully to verify proper function.
•
Patients are restricted from undergoing an MRI study within 30 days of the pH study.
•
Prior to the pH study, the patient should not eat or drink for a minimum of 6 hours.
Storage Store in a controlled room temperature environment at 15–45 °C (59–113 °F).
Electromagnetic Compatibility Electrical equipment for medical use requires special electromagnetic compatibility (EMC) precautions and should be installed and serviced according to the documentation of device. Portable and mobile communication equipment can affect electrical equipment for medical use. For additional information on electromagnetic compatibility, refer to Electromagnetic Compatibility Declaration (EN IEC 60601-1-22) on page 39.

Bravo pH Receiver Description The Bravo pH receiver is lightweight and compact. It fits into a carrying case that comes with a strap and a belt clip allowing patients to carry it over the shoulder, attach it to a belt, or carry it in a pocket (without the carrying case). This flexibility allows the patient to carry the receiver throughout the study period.

Clinician Interface The clinician interface is used by medical personnel to program the receiver for a pH study. This interface is hidden from patients by the front cover, which cannot be casually opened. This prevents patients from interfering with receiver settings during a study. To open the front cover: 1. Use a pen or paperclip to press the release (Figure 3). 2. Open the cover to access the receiver controls and display (Figure 4).

General Guidelines Follow these guidelines when working with the receiver: •
Always replace the battery at the start of a pH study. This reduces the risk of lost data during the study (refer to Replacing the Main Battery on page 31).
•
Always clean the receiver after each study (refer to Cleaning the Receiver on page 31).
•
Always turn off the receiver if it is not in use.
•
Each time the receiver is turned on, you must reset the time and date.
•
Set study parameters at the start of each study.
Turning the Receiver On and Off 1. Open the front cover (refer to Figure 3).

Calibrating Capsules
Calibrating Capsules Calibration is necessary to ensure that the capsule is reading pH levels properly. To prepare for calibration: 1. Set up the calibration stand on a level surface and placing a clean calibration tube into each of the four holders. 2. Check the expiration date on the buffer fluid bottles (next to
on the label)
3. Fill the 4 tubes in the calibration stand half full. The fluid should be barely visible above the calibration stand tube holder. • Tube 1: pH 7.01 buffer • Tube 2: Sterile water • Tube 3: pH 1.07 buffer solution • Tube 4: Sterile water Use buffer solutions at room temperature (20–25 °C, 68–77 °F) for each calibration procedure. 4. Check the expiration date on the capsule (next to
on the label).
5. Without bending or kinking the delivery device, carefully remove the Bravo pH capsule with delivery device from the external shipping box and then from the inner pouch (Figure 6). Caution: Avoid bending or kinking the delivery device. Sharp bending or kinking can damage the delivery device, which will require the device to be discarded before use.
Figure 6. Remove Bravo pH capsule with delivery device from pouch.
6. Remove the capsule’s plastic cover, the reference sensor cover (soaker bulb cover), and the magnetic clip (Figure 7). Set the magnetic clip aside.

10. Carefully place the capsule into the pH 7.01 buffer solution calibration tube. Caution: When placing the capsule into the calibration tube, do not allow either part of the pH sensor (i.e., short, silver-colored antimony and long, clear reference sensor) to catch on the edge of the calibration tube. Stay clear of the tube edge, and carefully lower the capsule into the solution. Damage to the antimony or reference sensor can occur if it catches on the tube edge. Any damage to the pH sensor will require the delivery device to be discarded before use. 11. Ensure that the capsule is completely covered in with the buffer solution. Gently agitate the capsule to remove any air bubbles. 12. Allow the capsule to remain submerged for at least 10 minutes prior to calibration. 13. Unlatch and open the receiver cover. Turn the receiver on and place it on the calibration stand (Figure 9): • For a receiver with the attached belt clip, set the receiver into the molded recess in the calibration stand base.

Calibrating Capsules • For a receiver without the belt clip, first place the receiver adapter into the molded recess in the calibration stand base, then place the receiver into the adapter. 14. Move the cursor to select Cal from the main menu, then press enter. This message appears: Cal Capsule 1 Yes No
15. Select Yes, then press enter. This message appears: Listening for Capsule 1:
Notes: • Ensure that the capsule is completely covered with pH 7.01 buffer solution. • Do not move the calibration stand during this process. • Do not move the capsule while it is in the buffer solution after you have initially agitated it to remove any air bubbles. The receiver identifies the pH capsule and displays the ID number for the capsule. Note: If the receiver does not identify the capsule, refer to Troubleshooting on page 33. 16. Confirm that the capsule ID number (for example, 2144) on the receiver display is the same as the number printed on the delivery capsule ID tag (Figure 10). receiver display
delivery capsule ID tag number
Figure 10. Match the ID number with the Bravo pH receiver display.
• If the ID numbers match, move the cursor to Yes and press enter.
