ResQGARD™
 (Impedance Threshold Device)

The ResQGARD is an Impedance Threshold Device (ITD) that provides a safe, simple and convenient way to treat states of low blood pressure in spontaneously breathing patients.

Animal and clinical studies have shown that the ResQGARD increases blood pressure during hypotension from a variety of causes, for example:

  • Orthostatic intolerance
  • Hypovolemia
  • Heat shock
  • Dialysis
  • Blood donation

The ResQGARD provides therapeutic benefit as soon as a patient begins to breathe through it.

The ResQGARD can be used on a facemask or with a mouthpiece.




Using the ResQGARD with a Facemask

1. Connect the ResQGARD to the facemask.
2. Explain to the patient that they will feel some slight resistance when
inhaling. This means that the device is working and helping to
improve blood flow.
3. Hold the mask over the nose and mouth maintaining a tight facemask
seal.
4. A ResQStrap can be used to hold the ResQGARD in place.
5. Breathe @ 10–16/min.
6. Inhale slowly (over 2–3 secs) and deeply; exhale normally.
7. If supplemental oxygen is desired, connect the oxygen tubing to the
port and deliver up to 15 lpm.

How It Works

During inspiration, a negative pressure (created
from expansion of the thorax) draws air into the
lungs. When inspiratory impedance is applied to
the breathing circuit, it enhances the negative
pressure (vacuum) in the chest, which pulls more
blood back to the heart, resulting in increased
preload and thus, enhanced cardiac output on
the subsequent cardiac contraction.

Using the ResQGARD with a Mouthpiece

1. Connect the ResQGARD to the mouthpiece.
2. Explain to the patient that they will feel some slight resistance when
inhaling. This means that the device is working and helping to
improve blood flow.
3. Place the mouthpiece into the mouth and maintain a tight seal with
the lips.
4. Breathe through the mouth only @ 10–16/min. An optional nose clip
prevents breathing through the nose.
5. Inhale slowly (over 2–3 secs) and deeply; exhale normally.
6. If supplemental oxygen is desired, connect the oxygen tubing to the
port and deliver up to 15 lpm.
