The Suncatcher™ pulse oximeter has been designed to help measure how much hemoglobin in blood is carrying oxygen throughout your body; otherwise known as oxygen saturation.

 

If you work in healthcare or if you have been hospitalized, you are likely to have used a pulse oximeter. You can find them in areas such as operating rooms, recovery, critical care wards, and ambulances. Due to covid19, oximeters are becoming popular and are proliferating in at work, schools, and airports as a way to test for early signs of sickness.

 

The Suncatcher™ pulse oximeter helps measure oxygen saturation. Oxygen saturation simply refers to the percentage of the available hemoglobin that carries oxygen in your blood. Oxygen enters the lungs and then is passed on into your bloodstream. The blood carries oxygen to the various organs in our body. The main way oxygen is carried in our blood is by means of hemoglobin. Hemoglobin carries oxygen through our blood vessels throughout the body.

1. Read all instructions first.

 

2. Install 2 new AAA batteries.

 

3. Open the clamp and insert a finger into the hole. Fingernail must be towards the display. Make sure the finger is all the way in the oximeter. Do no move finger when the measurement has begun. Fingernail polish may block light transmission affecting SpO2 readings.

 

4. Press the power switch.

 

5. Read pulse rate and blood oxygen (SpO2) this may take up to 20 seconds.

 

6. The oximeter will automatically turn off after

%SpO2 value – peripheral capillary oxygen saturation is the percentage of oxygen-carrying hemoglobin to the total hemoglobin present in the blood.

 

Pulse rate value – Pulse rate (beats per minute)

 

Battery power – Displays power remaining in batteries.

 

Pulse bar graph – Shows the relative pulse strength of the pulse.

 

Power switch – When the pulse oximeter is off, pressing the power switch will turn on the unit. When the pulse oximeter is on, pressing the power switch will rotate the display orientation.

 

Pulse trigger – Pulse detected.

 

PI% value – Perfusion Index is an indicator of the relative strength of the pulsatile signal.

 

Pulse graph – Shows relative pulse strength over time.

The Suncatcher™ Pulse Oximeter uses light to determine oxygen saturation. Light is emitted from light sources that go across the pulse oximeter probe and reach the light detector. If a finger is placed in between the light source and the light detector, the light will now have to pass through the finger to reach the detector. Part of the light will be absorbed by the finger and the part not absorbed reaches the light detector. The amount of light that is absorbed by the finger depends on many physical properties and these properties are used by the pulse oximeter to calculate the oxygen saturation.

 

The amount of light absorbed depends on the following:

  1. the concentration of the light-absorbing substance.
  2. length of the light path in the absorbing substance
  3. clean finger without fingernail polish

 

A finger is inserted into the probe. Above the finger are the light sources that emit light. In the finger is an artery that carries the blood the pulse oximeter is interested in and a vein through which the blood leaves the finger. Below the finger is the light detector. Hemoglobin (Hb) absorbs light. The amount of light absorbed is proportional to the concentration of Hb in the blood vessel. The blood vessels in both fingers have the same diameter. However, one blood vessel has a low Hb concentration ( i.e. low number of Hb in each unit volume of blood) and the other blood vessel has a high Hb concentration ( i.e. high number of Hb in each unit volume of blood). Each single Hb absorbs some of the light, so the more the Hb per unit area, the more the light is absorbed. This property is described in physics called “Beer’s Law”. Beer’s Law is the amount of light absorbed is proportional to the concentration of the light-absorbing substance by measuring how much light reaches the light detector, the pulse oximeter knows how much light has been absorbed. The more the Hb in the finger, the more the light absorbed.

 

The light emitted from the source has to travel through the artery. The light travels in a shorter path in the narrow artery and travels through a longer path in the wider artery. Though the concentration of Hb is the same in both arteries, the light meets more Hb in the wider artery, since it travels in a longer path. Therefore, the longer the path the light has to travel, the more the light is absorbed. This property is described in physics called “Lambert’s Law”. Lambert’s Law is the amount of light absorbed is proportional to the length of the path that the light has to travel in the absorbing substance.
