I would like to turn the call over to Roger Susi, President and Chief Executive Officer of IRadimed Corporation. Mr. Susi.
Thank you, operator. Good morning, and thank you for joining us on the call. I'm very happy to report that IRadimed has had yet another excellent quarter of revenue and earnings growth as reported in this morning's release, which unfortunately, I must add, was earlier only on the SEC site and not in the broader news sources until just minutes ago, as there was, as of yet, an unknown issue with the service used for disseminating our filings broadly. As mentioned in our earlier release, this was our top revenue quarter ever and the third in a string of our strongest growth quarters. I'll add that the trend of strong demand for our products remains very much intact, and thus we feel very good about the coming quarters as well.
As reported, our second quarter revenue was $12.7 million, nearly a 30% increase over the second quarter of last year. non-GAAP earnings were $0.26 or 116% over Q2 2021. I'm very pleased with these results and the hard efforts of our team. With a half year behind us and growing at the record levels, we look forward to achieving our guidance for the year. Though supply risks are very much with us on a near-daily basis, the team has succeeded in finding ways to prevail, and we feel that measures put in place these last months will continue to help us mitigate supply risks. Our sales team continues to perform well, increasingly driving customer demand for our products, with total Q2 bookings continuing to reach record levels, once again coming in higher than shipments for the quarter.
Additionally, the strong backlog provides great visibility and affords us the ability to maneuver and reallocate resources as supply issues may arise. Sales are well-balanced and strong from both the pump and monitor product lines, with excitement and interest growing for the new FMD product as well. Our engineering and regulatory teams continue to work extremely hard responding to FDA to clear their questions and obtain 510(k) clearance for our next generation IV pump, the MRidium 3870. A large written response will be filed in August, and from there, we expect to hear from FDA in September or October and learn the next steps. Assuming this FDA reply will be straightforward, the team will next turn their efforts towards obtaining CE mark for the 3870, allowing sales into EU countries.
Though with economic conditions in Europe as they currently are and with the euro having broken the buck, the business opportunities there are expected to be weak for some time. Regarding our new ferromagnetic detection system, we finished producing a small number of systems just at the end of the quarter. And along with an additional backlog of 12 units currently being prepared, we plan to report revenue for all these units in the upcoming Q3. As I said earlier, interest is building, and we expect the order rate to continue increasing in Q3. Regarding our financial guidance, with our current bookings trend and with the added visibility we have through a growing backlog, we believe we are well on track to attain the goals we have guided towards as well as our ability to continue growth at these record levels.
We are reiterating our guidance for the full 2022 revenue of $52.5 million-$53.2 million, GAAP earnings of $0.89-$0.95, and non-GAAP earnings of $0.96-$1.03. Additionally, for the third quarter this year, we expect revenue of $13.1 million-$13.3 million, with GAAP earnings of $0.21-$0.24 and non-GAAP earnings of $0.22-$0.25. Now I'll turn the call over to our new CFO, Jack Glenn, to introduce himself and review the financial results for the quarter. Jack is reaching out to us from home as he is suffering a bit from COVID, but as a strong CFO would do, he's on the phone with us today. Jack, please.
Thank you, Roger, good morning, everyone. Before summarizing the financial results for the quarter, I would like to take a moment to introduce myself. My career as a CFO has spanned over 25 years, with most of that time spent in the medical device industry. IRadimed is my fifth public company as CFO, and I'm thankful and excited to work with Roger and the IRadimed team to drive future growth and success. Now on to the financial summary. As in the past, our results are reported on a GAAP basis and non-GAAP basis. You can find a description of our non-GAAP operating measures in this morning's earnings release and a reconciliation of these non-GAAP measures to the GAAP measure on the last page of today's release.
As we reported earlier this morning, revenue in the second quarter of 2022 was $12.7 million, an increase of 29.7% compared to the second quarter of 2021. Revenue from domestic sales increased 34.5% to $10.8 million, and revenue from international sales increased 7.8% to $1.9 million. Overall, domestic revenue accounted for 85% of total revenue for Q2 2022, compared to 82% for Q2 of 2021. Device revenue increased 50.4% to $8.8 million. This was driven by a 45.7% increase in monitor revenue, resulting from continued strong execution by our sales team on the conversion of the sales opportunity pipeline.
The average selling price of our MRI-compatible IV infusion pump system during the second quarter of 2022 was approximately $37,400, compared to approximately $41,600 for the second quarter of 2021. This decrease relates to higher international unit sales and an unfavorable product sales mix compared to the same period in 2021. The average selling price of our MRI-compatible patient vital signs monitoring system during the second quarter of 2022 was approximately $48,700, compared to approximately $39,700 for the same period in 2021. This increase relates to higher domestic unit sales and price increases that we began implementing during the second half of 2021.
Revenue from disposables and services decreased 1.7% to $3.4 million for the second quarter of 2022, while revenue from our maintenance contracts was consistent at $500,000 for both periods. The gross margin was 79.7% for the 2022 quarter, compared to 74.7% for the 2021 quarter. The increase in gross margin percent is primarily due to maintaining the price increase implemented during the second half of 2021 and higher domestic sales compared to the same period in 2021. While the supply chain remains challenging, we believe any negative impact from higher costs will likely be limited and partially offset by higher unit production levels, resulting in gross margins consistent with our historical ranges.
Operating expenses were $6 million or 47% of revenue, compared to $5.5 million or approximately 55.9% of revenue for the second quarter of 2021. On a dollar basis, this increase is primarily due to higher sales commissions and sales activity, as well as higher research and development expenses related to the next generation pump, offset by reduced legal and professional fees. As a result, income from operations grew 126% to $4.2 million for the 2022 quarter. We recognized a tax expense during the second quarter of 2022 of approximately $939 ,000 resulting in an effective tax rate of 22.5%, compared to a tax expense of approximately $388 ,000 in the 2021 quarter.
This increase is due to higher sales or higher taxable income, partially offset by benefits associated with stock-based compensation and research and development credits. On a GAAP basis, net income was $0.26 per share, compared to $0.12 for the 2021 quarter. On a non-GAAP basis, adjusted income was $0.26 per diluted share for the 2022 quarter, compared to $0.14 for the second quarter of 2021. Cash from operations was $3.1 million for the six months ended June 30th, 2022, down from $4.5 million for the same period in 2021. This decrease was primarily due to increased accounts receivable on the higher sales volume.
For the three months ended June 30th, 2022 and 2021, our free cash flow, a non-GAAP measure, was $1.5 million and $3.5 million respectively. With that now, I will now turn the call over for questions. Operator?
Thank you. As a reminder, to ask a question, you will need to press star one one on your telephone. Please stand by while we compile a Q&A roster.
Our first question comes from Scott Henry with ROTH Capital Partners. You may proceed.
Thank you. Good morning. Just a couple questions. First on the FMD, it sounds like if I heard correctly, there should be at least 12 units sold in Q3. Could you talk about how should we think about revenue per unit for that product?
Yeah, Scott, this is Roger. Maybe I'll take that first. The initial ones I suppose are being sold with pricing that we're feeling our way through. These have been at the upper 20,000 area, $27,000-$28,000. That's what you'll probably see for the initial couple of quarters as we get our toes in this water, right? From there, I hope, as you've seen what we've done with the pumps and the monitors, you know, that we get a little bit of uplift in our ASPs as you know, time goes on and the market conditions show us that we're on track with the right product.
Okay, great. For clarity, I know you said you would expect to hear from the FDA in kinda September, October on that next generation pump. I mean, obviously you would prefer final approval at that time, but do you think there's also, you know, potential for more correspondence? Or how should we think about what could happen in that timeframe?
Well, there's always a little more correspondence. Even when they're preparing the final release, that generally takes a whole month and just some back and forth, finishing touches to the final letter. That would be great. You know, we don't know how much capacity the FDA has right at this moment in time, though. We keep our eye on this group that does IV pumps, and they are rather short-handed. That will probably impact how fast they can work on anything in that IV pump group as well. We have no idea how to gauge that at this point. We'll see.
Okay. Great. Thank you. It sounds like we'll just think about Q4, and then, you know, hopefully it comes in at some point during Q4, that final approval. Shifting to the model, spending was sort of down across all categories in Q2 versus Q1. You know, I guess Q1 was a strong spending quarter. In general, were there any trends there, or would you just, you know, look at that as variation from quarter- to- quarter? Any trends there?
No.
Yes, Scott Henry.
You wanna take that one, Jack?
Yeah, sure. I would say, Scott, that, yeah, there's some variability between the quarters, but our spend is pretty much in line with what we, you know, we've been forecasting. There's been an increase in, you know, on the sales side, obviously, there's been an increase in our sales activities and our sales force, and then any of the increase in the spend on R&D will be, you know, tied to the efforts on the next generation pump that we're working on.
Okay.
The G&A side is pretty stable. There was a little bit of a decline in some of our legal and professional expense.
Okay. Then the final question, just on gross margins, you talked a little bit about it on the prepared remark, but my takeaway was, and I wanna see if I heard this correctly, Q2 was very strong. It sounds like going forward, gross margins are in fact getting stronger, but perhaps not quite as strong as Q2 would indicate. Is that the way I should think about that?
Yeah. I think that, you know, Q2 was
I would.
Oh, go ahead, Roger. Sorry.
Go ahead. Go ahead, Jack. Go ahead.
No, sorry. I was just gonna add to that. Yeah, I think that Q2 just kinda stood out a little bit, a little above the historical, but, you know, some of that was due to the product mix, as we mentioned. Our ASPs have been, you know, holding very steady. The other thing to note would be, I think, that, you know, as we, you know, the higher sales volume, we're absorbing more in our overhead and from the fixed overhead standpoint, so that certainly helps. I think, you know, in that historical range is kind of where we see it going forward.
Okay, great. Thank you for taking the questions.
Sure.
Thanks, Scott. Good to talk to you.
Thank you. As a reminder, to ask a question, you'll need to press star one one on your telephone. One moment for questions. I'm not showing any further questions at this time. I would now like to turn the call back over to Roger Susi for any further remarks.
Thank you. Again, it's with great pleasure that we report our record growth, especially in light of today's economic upheavals. The company is running very efficiently, and its products are being adopted at an accelerating rate. Our sales force is growing, and you will see that expansion plans to meet growth are being developed, and in fact, currently in initial stages of implementation. With that, I look forward to reporting our future success as the year progresses and to thank you all.
Thank you. This concludes today's conference call. Thank you for participating. You may now disconnect.
