Overview of the Spectra S1 Breast Pump

The spectra S1 electric breast pump is made by Spectra baby USA. It makes use of a natural nursing technology to extract breast milk and the suction levels mimics that of natural breastfeeding as closely possible. 

This natural nursing technology combines a gentle vibration and a soothing suckling action to stimulate the production of milk. It stimulates it the natural way a baby would do this and it also offers a more comfortable and easy pumping experience. 

Spectra S1 can work both for single and double pumping and you will get the best result when you use their baby accessories. 

The spectra S1 is blue and white in color with a very beautiful and attractive design. It comes in a pack which contains: 

  • One hospital grade breast pump
  • 2 medium sized flanges 
  • 46 oz large neck bottles (without nipples)
  • Two suction tubes 
  • 2 diaphragms 
  • 2 valves 
  • One AC wall adapter 
  • A bottle tote 
  • And a carry tote  

How to Use Spectra S1 and S2 Breast Pump

If you’ve just received your spectra breast pump, be it S1 or S2, they both have the same method of use.

It can be quite confusing to know what to do or how to use it because there are lots of pump parts and settings. 

Below is a guide on how you can assemble the spectra S1 breast pump parts and also tips on how to set it up and use it. 

How To Use Your Spectra Breast Pump: OBGYN and New Mom Shares Tips for Getting Started with Pumping

Assemble the backflow protector 

You will find three pieces for the backflow protector in the pack, a white silicone piece and two clear plastic pieces. 

The white silicon piece should be put on the clear plastic piece and then you snap the second clear plastic piece over the other side of the white silicon piece. 

This means that the white silicon piece will be inbetween the two clear plastic pieces. Then you connect the larger nub on the backflow protector into the spectra breast shield. 

The smaller nub will fit into the tubbing that connects to the pump. The work of the backflow protector is to prevent any milk from flowing from the breast shield into the pump. 

The plastic and silicone pieces will create a barrier between the tubing and the breast shield. 

The backflow protector is also what makes it a closed system. As it prevents milk from flowing into the pump, it also keeps the pump clean and free from the growth of molds in the breast pump motor and tubing.

Connect the tubing and the pump together 

The Spectra S1 comes with two pieces of tubing in case you want to do double pumping. If you want to do single pumping, you use just one piece of tubing.

Double pumping means that you pump both breasts at the same time while single pumping means you pump just one breast. 

If you want to double pump, you will have to remove the small white cap from the pump and connect one end of the tubing to the pump. Repeat this same procedure for the second piece of tubing if you are double pumping. 

You need to replace the tubing if it becomes loose over time or if it disconnects from the pump during the middle of your pumping session. 

Connect the other end of the tubing to the backflow protector 

In this third step, you connect the other end of the pumping tubing to fit into the small nub on the spectra backflow protector. 

If you are double pumping, you can go ahead and attach each tube into the backflow protector. 

The backflow protector has two sides, a large nub and a small nub.  If you have difficulty connecting the tubing, ensure that you are connecting the tubbing to the end with the small nub. 

The tubing does not easily fit into the large nub of the backflow protector. When pumping, no milk should be seen in the spectra pump tubing, if there is milk in there, you should stop pumping immediately. 

Inspect the tubbing and ensure that they are well fitted properly. 

Assemble the breast shield, the duckbill valve, and the bottle 

First of all, you twist the duckbill valve into the opening on the breast shield and then twist the bottle onto the breast shield. If you are double pumping, you have to repeat this step to give you two full set ups. 

The duckbill valve will drive the amount of suction on your pump and it needs to be replaced usually every 2 to 4 weeks. 

With frequent use, the duckbill valve will become loose and worn out due to use, washing, and sterilization of the pump parts. You will notice a gradual decline in the amount of milk you pump during each session. 

Connect the breast shield to the backflow protector 

Remember that one end of the backflow protector is already connected to the tubing, now, you take the other end and insert it into the spectra breast shield. Ensure it fits snugly. 

If you’ve done all the steps above, all the pieces of your pump should be set up and ready for use. 

Connect the power plug to the wall and the other end into the small hole on side of the spectra pump. Now, you can start pumping. 

Turn it on and test your pump before you put on the flanges. You would see the white silicon in the backflow protector pulse in and out due to the air pressure from the pump. 

Start the letdown mode and set the cycle to 70

Turn it on by pressing the power button to start pumping. The power button is in the center and it has a circle with a hash mark on it. 

Start off by pumping in letdown mode. There is a button in the center with wavy lines, push it and the cycle on the digital display will read 70. 

You can adjust this level of suction to your comfort. The lowest level of suction is 1 and the highest on the cycle 70 is 5. 

You can start off with level 1 and increase the suction until you are uncomfortable, then you go back down by one level. 

You can get a hands-free pumping bra to allow you multi-task while pumping. You won’t have to hold the breast shields and your hands will be free to massage your breasts and this can help you get more milk. 

This will also save you time as a busy mom. 

After the milk starts flowing, you can then switch to expression mode and set the cycle to 54 

This mode is a bit slower than the pump speeds and you can increase the level of suction as the speed decreases. You can press the button with the wavy line to switch to this cycle and then press the minus or plus button to get cycle 54. 

During expression mode, the level of suction can be increased all the way up to level 12 and you can start with 5 and gradually increase it until it gets a little too painful. 

Then you decrease the level down by one setting until you are comfortable with it. 

You stay at this speed and vacuum level until the milk stops flowing. When it stops flowing, you switch back to let down mode by pressing the button with wavy lines.

Continue pumping for 15 to 25 minutes until empty 

You can go ahead and pump for 15 to 25 minutes and if the milk stops flowing, you can switch back to the letdown mode/cycle 70. 

As the cycle decreases in speed, you may need to increase the vacuum level of suction to maximize the amount of milk you are able to pump. 

This mimics how a baby sucks if nursing directly. Initially, a baby starts sucking at high speed and after the milk tops flowing, the speed transitions to slow and strong sucks to draw out all the milk. 

When you are done pumping, you will feel empty. And when you are done pumping, ensure you reduce the level setting back to a low level like 1 or 2 before shutting off the pump. 

The spectra will remember the cycle and level for your next session after the pump is turned off.
