RECEIVING / INSPECTION

Remove the Precision Medical, Inc. EasyPulseFlow from the packaging and inspect for damage. If there is any damage, DO NOT USE and contact your Provider.

INTENdEd USE

The EasyPulseFlow flowmeter is intended for use by physicians, respiratory therapists, and other hospital personnel to administer selected doses of medical oxygen to patients suffering from hypoxia due to various etiologies and disease processes. The device delivers via nasal cannula a F

IO

2

of 100% oxygen at all settings when connected directly to 100% gas source. It is intended to be used as a device to provide continuous flow oxygen therapy or as an oxygen saving device that delivers pulsed volumes for oxygen therapy while reducing the drying of the patient airways.

WARNING

• The EasyPulseFlow is not to be used in the Pulse mode by patients who breathe through their mouths.

• dO NOT use oils, greases, organic lubricants or any combustible materials on or near this product. Wash and dry hands properly prior to usage.

• dO NOT use a humidifier when administering Oxygen therapy on pulse settings.

• dO NOT use pulse settings while patient is sleeping unless continuous pulse oximetry is utilized.

• dO NOT smoke in an area where oxygen is being administered.

• The EasyPulseFlow is designed to operate with a single lumen, adult cannula with a maximum length of 7 foot (2.1 m).

• Flowmeter must meet specified inlet pressure range, see

“SPECIFICATIONS”.

• To use Pulse, Flow Control Knob must be set to 5 l/min or greater.

CAUTION

• Only personnel instructed and trained in its use should operate the EasyPulseFlow.

• The EasyPulseFlow contains magnetic, ferrous material that may affect the results of an MRI.

• dO NOT autoclave.

• dO NOT gas sterilize with EtO (Ethylene Oxide).

• dO NOT clean with aromatic hydrocarbons.

• Avoid dropping the EasyPulseFlow or placing it in a position where it could fall and become damaged.

• The EasyPulseFlow may not be able to detect all respiratory efforts of the patient. (Shallow breathers may not be able to trigger the EasyPulseFlow.)

• Operating the EasyPulseFlow outside its range of operating conditions may affect its accuracy and performance.

PRINCIPLES OF OPERATION

The Precision Medical, Inc. EasyPulseFlow is a combination of two (2) devices, a traditional Thorpe tube flowmeter and a pulse oxygen conserver.

The EasyPulseFlow is designed to be used with low pressure oxygen systems at specified Inlet Pressure. It consists of a back pressure compensated Thorpe tube flowmeter, a conserving module, and a selector dial to choose between Continuous Flow mode or Pulse mode.

In the Continuous Flow mode the flowmeter operates similar to a traditional

Thorpe tube flowmeter: the flow is determined by setting the flow control knob to the prescribed flow. In this mode it is capable of delivering metered flows from 0 to 15 l/min and up to 24 l/min at flush flow.

In the Pulse mode the device operates as an oxygen conserver. Settings of 1 through 5 are available and supply a similar F

IO

2

to the patient as continuous flow. The conserving module controls the pulse size and timing to the patient. It supplies a pulse of oxygen at the beginning of each breath. This reduces the oxygen demand on the system and limits the drying of the airways. The oxygen is supplied to the patient through the nasal cannula.

OPERATING INSTRUCTIONS

WARNING

Read this User Manual before installing or operating the

EasyPulseFlow.

CAUTION

Inspect the EasyPulseFlow for visual damage before use,

DO NOT USE if damaged.

CAUTION

• dO NOT use pediatric, low flow nasal cannulas or oxygen masks with the EasyPulseFlow.

• dO NOT block the cannula connection or kink cannula tubing when the Conserver is in use, this may damage the EasyPulseFlow.

OR

1. Verify order/need for oxygen administration.

2. Connect flowmeter to oxygen gas source, as stated on Flowtube.

3. Turn Selector Dial to align indicator pointer with Continuous Flow setting.

4. Turn Flow Control Knob to obtain appropriate flow rate.

A. To increase, turn knob counterclockwise

B. To decrease, turn knob clockwise

C. Set flow by aligning center of Float Ball with indicator lines on flow tube.

D. To obtain maximum flush flow, turn knob fully counterclockwise.

6

NOTE: Flush flow is any flow above the last calibrated line on the Thorpe Flow Tube with an unrestricted flow, as per

“SPECIFICATIONS”.

5. Connect oxygen administration equipment via DISS connector on bottom of flowmeter.

6. Assess effectiveness of oxygen therapy to the patient with pulse oximetry or arterial blood gas.

7. If patient is stabilized on nasal cannula at ≤ 5 l/min, switch to

pulse-dose mode as follows:

A. Remove any type of humidity bottle.

B. Turn Flow Control Knob to obtain a continuous flow of 5 l/min or greater.

C. Select pulse setting from 1 to 5, by turning the Selector Dial to align Indicator Pointer with pulse setting.

NOTE: DO NOT adjust Flow control knob on flowmeter. i. Choose pulse setting equal to continuous flow setting

(e.g. if patient is on 4 l/min continuous flow choose a pulse setting of 4).

ii. If patient is on a ½ liter increment choose the next closest higher pulse setting (e.g. if patient is on 2½ l/min place patient on pulse setting of 3).

iii. Instruct patient that oxygen will only flow during the first part of inspiration.

iv. Assess patient/conserver interaction to assure pulsing is occurring.

D. Re-assess patient’s oxygenation status via pulse oximetry or arterial blood gas.

8. Amount of oxygen may be weaned either by decreasing the continuous flow rate on the Thorpe tube flowmeter if patient is on continuous flow or by decreasing the pulse of oxygen if on pulse mode.

(If patient is on pulse mode, oxygen may only be decreased in increments of one (1)).

9. To turn off flowmeter, turn the Flow Control Knob fully clockwise.

NOTE: If nasal cannula is disconnected while on pulse oxygen therapy. (The device should not pulse oxygen into the atmosphere.) Limit of three (3) pulses per minute .

MAINTENANCE / CLEANING

1. Disconnect all connections before cleaning.

As needed:

2. Clean exterior surfaces of the EasyPulseFlow with a cloth dampened with mild detergent and water.

3. Wipe dry with a clean cloth.

4. Store the EasyPulseFlow in a clean area free of grease, oil, and other sources of contamination.
