Pump Primer | How To Use Your Spectra S1 Breast Pump

Assembling the breast shield is easy, but there may be more parts than you’re used to.

The backflow protector consists of three parts: 2 clear plastic shells and a white diaphragm. The plastic shells are different sizes, with the smaller attaching into grooved portion of the diaphragm and the larger shell sandwiching the diaphragm from the outside.

If that description was confusing (don’t worry, it’s easier when you’re following along with pump parts in hand) here’s another way to think of it:

With the diaphragm in front of you and the “cupped” or concave side facing to the left, the large shell goes on the left and the smaller shell on the right.

The tubing attaches to the larger shell, and the smaller shell is what connects to the breast shield.

Finding the right settings for you

The most important thing to consider when you're pumping is your comfort.

As a quick reference, here are a few reasons why pumping may be uncomfortable:

• Using the wrong size flanges

• Too high of vacuum pressure

• Increasing suction level too quickly

• Too slow of a cycle speed

• Nipple trauma or infection

What settings you use and when you use them plays a significant role in how comfortable (and productive) your pump experience is.

To understand the pumping experience, it's helpful if we first cover infant sucking. That's what the pump is trying to emulate right?

Babies generally transfer well with a strong stuck of at least 150 mmHg of vacuum pressure. 1 Babies who use a lower sucking strength ~ 100 mmHg can have difficulties in maintaining and building their parent's milk supply.

One of the challenges pump manufacturers face is that the infant suck speed and strength is variable, meaning it isn't consistent throughout a feeding session. Babies tend to use softer but more rapid sucks in the first few minutes of feeding and transition to a slower, stronger feeding pattern.

The S1 gives you a bunch of flexibility in controlling both the rate of sucks per minute and the strength of each suck.

But with more control comes greater responsibility and greater opportunity to "over suction"!

So how to do you find the balance between a comfortable pump experience and a strong enough suction?

The answer lies in the vacuum pressure values the S1 can achieve.

There are five levels of vacuum pressure in the massage/letdown mode ranging from 50 mmHg ( on level 1), and I would guess somewhere between 180-200 mmHg level 5.

Note: There is no information from Spectra as to what levels correlate to with what vacuum pressure. They do state, however, that the mmHg levels in massage mode are less than their max mmHg level in expression mode. The max mmHg for Spectra USA S1 around 280 mmHg.

For massage/letdown mode I would encourage you to shoot for level 3 or higher before switching to expression mode.

In expression mode, start with the suction level that feels most comfortable and gradually increase the vacuum pressure during your pump session.

Not everyone can comfortably pump at the highest vacuum pressure and luckily there is no need to pump on the highest settings, but you should shoot for as high of a suction level as you can tolerate.

Just ballparking, shooting for suction level 8-10 I think is a realistic expectation assuming that you're using correctly sized flanges.

Need help with flange sizing? Check out our flange sizing guide, which outlines everything you need to know to find the best flange fit possible.

You can also play with the cycle setting to see if adjusting the number of cycles per minute allows for more comfortable pumping.

If my nips are especially sensitive because I've accidentally pumped at too high of a setting, I find increasing the cycle speed takes the edge off allowing me to keep the same suction level.

But don't be afraid to turn your pump down.

Painful pumping and oxytocin don't jive, and you need oxytocin to release your milk. Listen to your body and adjust accordingly.

Pumping tip: If you can find no comfortable combination of suction strength and cycle speed, you can just stick to the massage mode. Make sure you're keeping with the upper end of the suction speed though. And double check your flange size!

Trouble shooting

In a perfect world there would be no need to trouble shoot because we would never have an issue. Unfortunately, this is far from a perfect world and issues are bound to happen.

Here is the Spectra Manual for your reference but I did want to quickly a common issue.

Low or no suction:

• Make sure your membrane is securely attached to your breast shield and ensure there are no tears. If you're using duckbill valves, check to see if the opening is closed when not in use. If you're using "traditional" membranes, look to see if the flap lays flat against the membrane adapter body. Replacing the membranes/valves may solve the problem.

• Ensure there are no holes or kinks in the tubing and the tubing is securely attached to the motor and backflow protector

• Double check to make sure the backflow protector shells and diaphragm are securely connected

I hope you've found this primer helpful! It can be an exciting but overwhelming experience pumping for the first time or using a pump you've never used before.
