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
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.

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.

PRINCIPLES OF OPERATION
The Precision Medical, Inc.
devices, a traditional Thorpe tube flowmeter and a pulse oxygen conserver.
The
EasyPulseFlow is
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
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.
EasyPulseFlow

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.
Connect flowmeter to oxygen gas source,
2.
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.
as stated on Flowtube
.
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.
Assess patient/conserver interaction to assure pulsing is occurring.
iv.
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.
