1.2 About This Manual

Prior to use, the operator must be trained in the use of the NGPOD®, a system to assist in the placement confirmation of Nasogastric (NG) feeding tubes. The system consists of a detection device (hereinafter referred to as the NGPOD®) and a single-use disposable Sensor (hereinafter referred to as the Sensor).

If a software change occurs and the operation/specification for the device changes, new or additional operating instructions will be issued, if required.

1.3 NGPOD® and Sensor Introduction

Device Description and Applications

The NGPOD® is a device to assist in position confirmation of a NG tube and consists of a re-usable, portable handheld detection device and a single use fibre-optic Sensor tipped with a pH indicator.
It has been designed to be an alternative to conventional feeding tube position confirmation tests, delivering a visual indication of the pH environment of the NG tube tip. The result is a YES/NO indication, reducing the risk of clinical interpretation error.

The Sensor attaches to the NGPOD® handheld device. The NGPOD® handheld device couples light into the fibre-optic Sensor. Light reflected from the sensor tip is received by the pod. Data from the pod sensors is processed to assess whether the colour of the indicator has passed a threshold that corresponds to the sensor tip being in an acidic environment.

The NGPOD® can only be used with the NGPOD® fibre optic sensor. The system is intended to aid in the correct placement of NG tubes by detecting an acidic environment through a colour change in the pH indicator.
As the consequences of feeding tube misplacement can be very serious, the quick, clear indication delivered by the NGPOD® can facilitate safer and more efficient NG placement in the clinical environment.

This device is fully compliant with NPSA (National Patient Safety Agency) feeding tube positioning confirmation guidelines.

Intended Use

NGPOD® is designed to signal to the clinical practitioner that the presence of a substance with a pH below 5.5 has been detected. When the NGPOD® device is used in the correct manner, a positive signal can typically be understood to mean that the presence of stomach acid has been detected.
It is the responsibility of the practitioner, using the result from the NGPOD® device, together with their own skills and experience, to make the final judgement as to the successful emplacement of the feeding tube and therefore whether feeding may safely proceed. These instructions DO NOT replace local guidelines for NGT placement. NGPOD® has been designed to replace aspirate testing as a 1st line, bedside test to assist in the confirmation of nasogastric tubes.

If a user chooses to use the NGPOD® system following an attempt to obtain aspirate from the nasogastric tube,the Operating Precaution ‘If using after an attempt to obtain aspirate..’ should be observed – see below.

Contraindications

The NGPOD® system should not be used where a pH test is clinically contraindicated for assisting in nasogastric tube placement, such as when a patient’s condition may result in acid being present in the lungs, or where the respiratory tract may have a pH below pH 6.

1.4 Advisory Terms and Symbols

This section describes standard terms used to signal advisory statements and other messages in this manual and system labelling. Please read and understand this manual and all warnings and precautions before operating the

NGPOD® system.

• INSERTING THE SENSOR DOWN NG TUBE
• WARNING: Prior to use of the NGPOD® system, compatibility with the nasogastric tube(s) (NGT) to be used should be established. Please refer to Appendix 1 of this IFU for a list of validated NGTs, and the correct sensor for use with each NGT . If the nasogastric tube you wish to use is not included in Appendix 1 please contact NGPod Global for advice or to arrange a validation
• PRECAUTION: If the tip of the sensor is green/yellow, then it must not be used. Yellow discolouration indicates contamination

3.1.2 Carry out the NGPOD® test

Power on NGPOD® Handheld Device to perform Self-Test
Ensure the NGPOD® self-test cap is fully seated.
To power on, press and release the power button

When the device is powered on, the self- test begins automatically and takes a few seconds to complete. This checks the LED’s, internal sensors and the battery.
During the self-test, observe the LED light sequence (Red – Amber – Green) :

The LED lights will cycle through the above light sequence, if self-test is successful then the device will enter Sensor Check mode. This is indicated by a repeating sequence of three flashes of the amber LED followed by a single flash of the red LED.

DO NOT proceed if any of the indicator LEDs fail to illuminate during self- test.
If the NGPOD detects an error during self-test, the red LED will flash 4 times and the device will power off.
If the NGPOD detects low battery voltage, the amber LED will flash 10 times after the self test is complete. The NGPOD will continue to operate but arrangements should be made to replace the NGPOD at the earliest opportunity.

NOTE: The NGPOD® will remain in ‘Sensor-Check’ mode until the device has been connected to a new, unused Sensor and the software has validated all components are working

Sensor Check Mode

Remove NGPOD® handheld device self-test cap.
Open the Sensor package slightly from the corner (not fully) to expose the Sensor connector cap and retain the end of the Sensor in the packaging for protection.

Push the connector of the NGPOD® sensor into the collar of the NGPOD handheld device and rotate until you hear it click.
With the Sensor connected the device automatically runs through the Sensor Check.

If successful, the green indicator light will briefly illuminate and the device will enter pH test mode, signified by a repeated flashing amber light every second. Disconnect NGPOD® handheld device from the Sensor.
If the NGPOD fails to enter pH test mode with the sensor connected correctly, the sensor has failed the sensor check.
Discard the sensor and try agin with a new sensor.

THE DEVICE IS NOW READY TO BE USED

NOTE : The NGPOD® will power off after five minutes to conserve battery power. If the unit powers off, repeat the self- test as above

Clear the NG tube

When the NGPOD system is used for a repeat NG Tube position test consider insufflating air in the NG Tube before attempting to insert the NGPOD sensor.

• NOTE: This will clear any debris from the end of the tube and dislodge the tip of the NG tube if it is against/adjacent to the gastric mucosa. The patients medical condition must be considered prior to insufflating air down the NG tube, and if there is any doubt as to whether this is appropriate, air should not be insufflated
• NOTE: In order to maintain the ability to successfully pass the NGPOD Sensor it is important that local or national guidelines in relation to the care of the NG Tube are followed to prevent the obstruction of the lumen of the NG Tube

Insert sensor into tube

Remove sensor from packaging, Insert the Sensor tip into the NG tube and gently advance the Sensor slowly down the NG tube until the NGPOD® Sensor connector is reached.
NB: The sensor is not attached to the POD during insertion

• WARNING: Do not touch the tip of the sensor or allow it come into contact with any liquid prior to insertion into the nasogastric tube
• NOTE: NG Tubes differ in exact length, the NGPOD® Connector may not come into direct contact with the NG Tube Connector. However, if the sensor cannot be advanced to closer than 5mm from the NG Tube Connector the sensor tip is likely to be at the distal tip of the NG Tube
• NOTE: Take care not to create any sharp or permanent bends in the sensor
• PRECAUTION: Do not use force to advance the Sensor, the NG tube may be displaced, blocked or kinked.
  Follow local policy for instructions on checking tube patency and position

When the amber LED light is flashing intermittently, press and release the button. The result will display in 4 seconds

GREEN LED light indicates that the sensor tip is in a pH environment associated with the stomach. Follow local policy to commence feeding or administer medications.
RED LED light indicates that the sensor tip is in a pH environment NOT associated with the stomach.

When a red LED light displays, DO NOT proceed with feeding or administration of liquids. Whilst the sensor is in place the NG tube may be advanced or withdrawn in small increments.
Refer to National/local policies and guidelines on repositioning and re- testing

WARNING: It may take up to 5 minutes following initial insertion of the NGPOD Sensor and performance of a pH test for a Green Tick result to occur. This should be anticipated in patients where a higher pH may be expected (eg patients on acid reducing medication and/or patients with low residual stomach volume due to continuous feeding regimes)

WARNING: Medications affecting pH
The pH can be affected by factors such as; medication and frequency of feeds. Check whether the patient is on an acid inhibiting medication. Medications such as antacids, h2 antagonists and proton pump inhibitors can affect the gastric pH. The results of the NGPOD® test should be documented. If the patient is on medication that could elevate the pH level of gastric contents, refer to local policy and instructions for checking gastric pH

WARNING: Dilution of gastric acid by enteral feed
The presence of enteral feed/food in the stomach may alter the pH. If the test fails four times, remove and discard the sensor, wait for up to an hour to allow time for the stomach to empty and the pH to fall and then retest. The time interval will depend on the clinical need of the patient and if they are on continuous or bolus feeds

PRECAUTION: Lens dirty/ not clean
Check the NGPOD® lens. If the lens appears dirty or debris is visible, clean the lenses according to the cleaning instructions on page 16, then repeat the NGPOD® test from the beginning

WARNING: Excessive/abnormal gastric secretions
The NGPOD® device works by responding to a colour change when the tip of the sensor comes into contact with acidic liquids. Please note that patients experiencing excessive or abnormal gastric secretions may have higher levels of acidic liquids in the Oesophagus and Pharynx. The NGPOD® should not be used if there is a risk of a positive result through contact with acidic liquids in areas other than the stomach

Document test result

Follow local policy for recording test results in patient’s medical records or on a test monitoring chart.

WARNING: If the patient is subsequently moved before feed is administered, then a re-test should be conducted to ensure that the NG tube has not become dislodged from the position that it was in when the test was conducted
WARNING: If the patient vomits during or immediately prior to the NGPOD® test then the user should revert to X-ray for NG placement confirmation as there is a possibility of gastric contents in the lung which could result in a positive result for a tube placed in the lung

NOTE: After feeding, the NG tube should be flushed as per local policy

3.1.3 Removal and disposal of equipment

Remove the Sensor connector from the NGPOD®
Replace the cap onto the NGPOD®
Gently withdraw the Sensor from the NG tube

NOTE: AFTER USE, ON VISUAL INSPECTION THE SENSOR TIP SHOULD BE GREEN/YELLOW. IF THE SENSOR TIP IS STILL BLUE, DO NOT COMMENCE FEED AND REPEAT TEST USING A NEW SENSOR

Dispose of Sensor in clinical waste

WARNING : During pH testing, the Sensor has contact with gastric contents.
Therefore, used Sensors carry a risk of infection

WARNING : On removal of the sensor from the nasogastric tube, dispose of immediately and avoid any cross-contamination with the NGPOD hand-held device (POD)’

Following completion of every NGPOD test cycle, i.e. a green or persistent red result has been obtained and testing stopped, the device should be turned off by pressing and holding the power button until the amber light flashes five times. This procedure resets the device ready for a test on the next patient.
