Thanks John. Good afternoon, everybody and we hope you're well. Even with the volatility in the economic environment, we are enjoying 2023 to date much more than last year. ICU Medical is operationally running well and largely back to playing offense and serving and expanding customers with the proper balance of time between internal self-help versus commercial focus. The macro environment eased a bit with finally some relief in the supply chain as freight, fuel and foreign exchange were all at their best levels in a while in Q1 and the rollover and labor inflation did materialize predictably. Global demand was healthy in Q1 with the US having improving admissions. Like everyone in our industry, we want to first start by thanking all of our customers and their frontline workers for trusting us to serve you during these times. We hope today's call is shorter and we'll use the time to discuss the Q1 revenue performance of our reporting segments as we said we would define them starting in 2023. Give the best color on revenue performance for these segments in the near-term, explain our profitability in Q1 and outline the items in the near-term that impact this level both positively and negatively, characterize those items in the context of the comments from the year-end call on what comes back in the medium term and long-term and what is permanent. Update the normal housekeeping items including quality remediation integration and separation status. And reiterate and check on our progress against our key short-term priorities that we outlined on to start the year and we'll skip any comments on longer term value creation and self-help and just get to the financials. We finished the quarter with $556 million in adjusted revenues. Adjusted EBITDA came in at $102 million and adjusted EPS was a $1.74. Revenue growth was 7% on a constant currency basis and 4% growth reported, and we had just over 200 basis point sequential improvement in gross margins, largely due to having a healthier supply chain with better service levels and the improving macro landscape. We did have a comparable quarter of inventory investment into the business and believe we are near peak on that to sustain the appropriate service levels. Relative to Q4, currency eased a bit, but did not materially improve earnings as both the Mexican peso and Costa Rican local currency strengthened meaningfully against the dollar. At the highest level, we feel better about revenue growth for each product line where we've been historically stable, meaning legacy ICU and revenue recapture, where we're now stable, meaning legacy -- the legacy Smiths Medical portfolio. Near-term profitability is impacted with some duplicative IT costs as we separate from Smiths IT systems and by decisions we're making to improve working capital and cash flow like we did relentlessly for many years. So let me start with our Consumable segment, which is our largest and most profitable segment. We had $236 million in revenue, which was up 1% on a constant currency basis, and minus 2% reported with customer demand good across all product lines. Going a bit deeper, there were a few different drivers that will become clearer over the balance of the year. The legacy ICU IV therapy product lines, which are the largest component of the segment, had a record quarter with the business being the largest -- its largest its ever been. That growth was driven by new customer wins, strong underlying census, and increased capacity and ability to serve the market. We continue to focus on clinical differentiation and there was a publication in April's Journal of Infection Control and Hospital Epidemiology, which highlights the favorable infection control features of our Clave needlefree connector technology. The growth in IV therapy was offset by the Vascular Access portion of this segment having the lowest level of sales in the five quarters we've owned the business. This low level was driven by customer losses that were still occurring until recently. We believed this to be bottom and it feels very similar to the IV consumables and pump losses when we purchased Hospira, when customer losses were still felt in the four to six quarters post deal. The other components of the segment are oncology and tracheostomy, both of which had year-over-year improvements, and both those businesses will be benefiting over the balance of this year from increased capacities. In the near-term, we believe all four underlying lines are improving commercially and operationally, and with the losses predominantly out and improve capacities in, we should start seeing the benefits of this in Q2. We have the right to win in all these categories and are focused on the innovation between the legacy Smiths products and the legacy ICU products. Moving to Infusion Systems, which is the combination of the legacy ICU LVP pump business and the legacy Smiths syringe and ambulatory pump businesses. This segment reported $162 million in revenues, which equated to 21% growth constant currency or 17% reported. Q1 of 2022 was obviously miserable last year, which made an impact. But the core message is each of the product lines is expected to increase on a year-over-year basis. The legacy Smiths product lines, we expect to be getting closer towards historical levels, meaning they're still down from what we would deem normal levels, but improving quickly. We see that most directly in the hardware sales were both ambulatory and syringe hardware improved quarter over quarter. Regarding the legacy ICU portfolio of LVPs, we've had a good signings year-to-date, increased our install base again in Q1, also increased our number of EHR integrated customers. We continue to believe our LVP line of infusion pumps addresses the most important clinical issues and in addition to being recognized as the -- in addition, being recognized as the best-in-class smart pump in EHR integrated pump for the past six consecutive years. Additionally, we're starting to see some commercial benefits of having a full infusion device portfolio between Smiths Medical and the ICU Medical portfolios. We continue to believe, as we said in the previous few calls, the customer attention is generally back with bandwidth to have real discussions as some of the fatigue from COVID has passed and the acceptance of inflation and the costs of nursing, et cetera have been internalized. Yes, the stresses of the current environment do make it a bit bumpier for decision making, but we don't believe over the medium term relative to our size, there's any change in our competitive opportunity. And we're focused on commercial execution here in a more action oriented market. Finishing the business unit discussion with Vital Care, which had $158 million in revenue with growth of 6% on a constant currency basis and 3% reported. IV solutions, the largest portion of Vital Care improved sequentially and was close to flat on a year-over-year basis, which was the net effect of some undersupply from Pfizer being tight on inventory on certain SKUs, both offset by some price improvement that we received. The growth in the segment was driven by the combined critical care product lines and the temperature management franchise. That temperature management product line does go hand in hand with our infusion and anesthesia oriented businesses. It's important to get that right as it contributes attractive margins and is still meaningfully below historical levels. The short story message here is our differentiated legacy ICU businesses are doing well and we're focused on regaining some of the lost revenues in the Smiths categories that are outlined in our investor presentations. We're operating with better service levels for customers and believe in Q2 we'll have all three of the segments growing year-over-year and have hit the bottom on the Smith's product lines that were going backwards. We're already impacting the self-inflicted challenges on infusion pumps, temperature management and tracheostomy. And now I've had more time with stable Vascular Access supply under our watch to begin to improve there. As a result, we've been more reliable for customers and able to engage in rebuilding the trust in service as the products have always been well liked and the reasonable underlying demand and improving census work in our favor. On the last call we tried summarizing the various headwinds to earnings last year in 2022, their impact on gross margin rate and which of the items were possible to recoup over the near medium and longer term. As a reminder, two of the largest three buckets were freight and logistics, currency and obviously mix as we lost revenues in some of the higher margin categories. We focused on driving improvements on expedited freight and domestic lane costs as we increased inventory levels and we see some relief in fuel surcharges. However, no meaningful profit improvement was really related to currency as the dollar weakened in our core manufacturing sites. Brian will go through the sequential improvement in gross margin in more detail. We just wanted to note as it came in higher than our target for the year, that we just can't roll that through the full P&L yet as the continuing and rollover inflation is real. And we don't want to make a mistake given what we went through last year. And we still have work to do to offset inflationary effects and the impact of lower production as we address working capital. But clearly we spared no expense last year in the supply chain, raw material procurement, et cetera. And in the medium to longer term, there's clear opportunity for improvement. Just a few quick notes on the housekeeping front and then I'll come back to our priorities for the year. On quality, we had a long list of normal notified body inspections during the quarter. We did have a thorough FDA inspection in Q1 at the legacy Smiths corporate office, which was mentioned on the last call a bit earlier than we had anticipated. We had a few fair and manageable comments from the inspection that were in line with the work we've been doing to address the root causes of the Smiths Medical warning letter. We've made heavy investments into remediation and believe the majority of remediation work will be done over the next few months and spend will ramp down over time. This part feels very similar to Hospira and our collective previous experiences, and we have the right people have been through the exact same experience and our team is fully embedded into the operation. Same speech on the warning letter, the existence of the warning letter while undesirable is the regulatory agency trying to move the ball forward, and we talked about how these regulations give us the right to participate. Again, regardless of where it appears on the P&L, we're spending heavily, so making progress here is extremely important to us. In addition to the quality improvements, another current topic is our separation from Smiths IT systems as we bear some duplicative costs this year, and successful execution is important as we've seen the challenges in the industry from systems cutovers. Over the next few weeks, we'll fully separate from Smiths and should exit all TSAs within 18 months of closing. Standing on our own is the first step towards real integration next year to capture the next wave of synergies in manufacturing, supply chain and functional support over time. It's also important to the extent we want to be able to make any decisions on the underlying portfolio. Broader production and logistics operations in the quarter improved again, and really the current challenge and opportunities optimizing the interplay between production output, the right level of inventory and working capital as we were scrambling for most of last year, and it takes time to get this right. We wanted to reiterate our priorities for 2023 that we outlined in the last call so investors can assess our progress in light of the comments we've made today. Our key goals for the year were as follows. Deliver revenue growth as expected in our differentiated business units while progressing the key product platforms; progress our quality remediation and ensure quality for patients in high compliance for regulatory authorities respectively; focus on cash flow, again by improving working capital and addressing all the available items on the P&L whether above or below the line; lay the groundwork via separation, and then integration for capture of the remaining synergies; and lastly, rationalize the portfolio, which becomes easier after separation and stability. To close, we're getting back to normal operations and the customer logic that underpinned this project continues to make sense. Like with the Hospira transaction, we're changing the conversation from the historical perception of Smiths to demonstrating our value through innovation and service. The core premise of the Smiths transaction is to enhance the product offerings for the categories that drive our returns, as well as add logical adjacencies predicated on the same characteristics of sticky categories, low capital intensity, single use disposables, where there's opportunities to innovate and participate in a logical industry structure. These portfolios make sense together and we're working on how to integrate them either literally or economically when sensible. More doors are being opened as a result of having a broader set of items that are mandatory for care and it's slowly starting to show up on the P&L. While the pandemic introduced substantial volatility, strategically we do think the weaknesses it exposed in the healthcare supply chain add to the argument for all participants to be healthy and stable, which has been our commentary since we became a full line supplier. Smiths Medical also produces essential items that require significant clinical training, hold manufacturing barriers and in general are items that customers do not want to switch unless they must. The market needs Smiths Medical to be a reliable supplier, and the combination positions have better. Our company has emerged stronger from all the events of the last few years. We've gotten knocked down a bit, but we're getting closer to the top of the hill to drive value out of the combination. Thank you to all the customers, suppliers, and frontline healthcare workers as we improve each day. Our company appreciates the role each of us must play. And with that, I'll turn it over to Brian.
