Thanks, Doc. Before I begin, let me remind all of you that the sales numbers we are covering as well as our financial statements are available on the investor portion of our website for your review.
Our total revenue for the first quarter of 2012 increased 5.7% to $75.5 million and compared to $71.5 million in the same period last year. Net income for the first quarter of 2012 was $7.6 million or $0.53 per diluted share as compared to net income of $8.1 million or $0.50 per diluted share for the first quarter of 2011.
Now let me discuss our first quarter revenue performance by market segment. You can also view our detailed market segmentation in our earnings press release.
For the first quarter of 2012, sales from the infusion therapy market increased 9.6% to $51 million and represented 67.5% of our total sales. This growth was attributable to strong performance of needlefree connectors, primarily CLAVE and MicroCLAVE as well as a Custom Sets. More specifically, sales from CLAVE and MicroCLAVE increased 12.9% to $28.3 million, compared to $25 million a year ago, representing a 37.4% of our total revenue.
Custom infusion sets were up 7.4% year-over-year to $19.6 million or 25.9% of total sales. We expect sales in infusion therapy to increase approximately 6% to 9% in fiscal year 2012 from fiscal year 2011 and to be driven by both needlefree connectors and Custom Sets.
As competitive volume and price pressures continue during the first quarter, sales from the critical care market were down 14.4% to $13.6 million compared to $15.9 million a year ago and comprised 18.1% of our total sales. We believe that critical care represents a good value proposition for our customers worldwide, and we continue to invest in these products to return them to positive growth.
Given the current market conditions, we continue to expect critical care sales to decrease year-over-year by approximately 4% to 8%. Sales from our oncology market grew 29.9% to $6.4 million compared to $4.9 million a year ago and represented 8.5% of our total sales for the first quarter. On a sequential basis, sales from the oncology market were up 19.9% based on the current demand, backlog of conversions and expected growth opportunities, we expect sales from this market to increase approximately 35% to 45% for fiscal year 2012.
Our other product category, which primarily includes products in the renal and enteral market grew 10% year-over-year to $4.5 million, representing 5.9% of our first quarter revenue. This growth was primarily due to TEGO, which increased 9% year-over-year to $2.2 million and Orbit, which we have now stopped producing.
We expect sales in this product category to increase approximately 3% to 6% this year. Now for our first quarter sales by distribution channels. Domestic sales in Hospira were up 4.1% year-over-year to $28.8 million and were driven by strong performance at CLAVE and MicroCLAVE needlefree connectors as well as Custom Sets and Standard Oncology products. For the first quarter of 2012, domestic sales to Hospira represented 38.2% of our total revenue compared to 38.8% for the same quarter of 2011. Our non-Hospira domestic sales increased 2% to $26.7 million year-over-year as double-digit growth in infusion therapy and oncology was partially offset by unexpected increase -- decrease in critical care.
International sales were up 13.6% to $19.9 million year-over-year, representing 26.3% of our total revenue and were driven by double-digit growth in fusion therapy, oncology and other products, partially offset by lower critical care sales. Growth came primarily from both Europe and the Pacific Rim. FX from Europe negatively impacted our sales by approximately $400,000 year-over-year.
Our first quarter gross margin was 46.3% compared to 48.4% a year ago and 47% in the previous quarter. The decrease in gross margin was attributable to utilization cost pressure from our new factory in Slovakia, which did not start up until the end of March of last year, manufacturing inefficiencies and price reductions in critical care. We expect our gross margin to be in the range of 47% to 47.5% for the full fiscal year of 2012.
SG&A expenses decreased by 8.6% year-over-year to $20.9 million compared to $22.9 million for the first quarter of 2011. The 2011 SG&A included $2 million of one-time expense from the long-term retention plan payout. Excluding this one-time expense, SG&A was almost flat year-over-year.
Overall during the first quarter of 2012, slightly higher sales and marketing, SG&A expenses were offset by lower legal costs. As a percentage of sales, our SG&A expenses were 27.7% compared to 32% a year ago. We expect SG&A as a percentage of total revenue to be 26.5% to 27% for the full fiscal year of 2012.
Our research and development expenses increased 31% to $2.7 million compared to $2.1 million for the first quarter of 2011. This increase was in line with our expectations as we continue to invest in new products for all our target markets. We expect our research and development expenses to be about 3% of revenue for the full fiscal year of 2012. Our tax rate for the first quarter was 34%.
Our operating income for the first quarter of 2012 totaled $11.4 million or 15.1% of sales compared to operating income of $12.2 million or 17.1% of sales a year ago.
Our EBITDA totaled $16.3 million compared to $17.1 million for the first quarter a year ago.
Moving to our balance sheet and cash flow. As of March 31, 2012, our balance sheet remained very strong with no debt and $184 million in cash, cash equivalents and investment securities. This equates to approximately $13 per outstanding share. Additionally, we have approximately $251 million in working capital. It's also worth noting that at the end of the first quarter, our inventory level decreased to $37.3 million compared to $40.4 million as of December 31, 2011, and $51.2 million as of March 31, 2011. During the first quarter of 2012, we generated $18.3 million in cash flow from operating activities.
Our capital expenditures totaled $3.6 million during the quarter and primarily included machinery, equipment and molds for our plants in the U.S. Day sales outstanding for the first quarter were 50 days. We expect DSOs to be approximately 55 to 60 days in the foreseeable future, which is an improvement from our historical DSOs.
Now let me update you on our financial guidance for fiscal year 2012 and the second quarter. Based on the current business trends, we reaffirmed our previously announced revenue guidance for the full fiscal year of 2012 and expect to generate revenue in the range of $318 million to $330 million. Our new market segment basis we expect our fusion therapy sales to increase the year-over-year approximately 6% to 9%. We expect critical care to be down approximately 4% to 8%. And we expect our oncology market segment to be up 35% to 45%. We expect our other category will be up 3% to 6%. We are also reaffirm our earnings guidance and expect our diluted earnings for the full fiscal year of 2012 to be in the range of $2.45 to $2.70 per share.
For modeling purposes, our tax rate is expected to be 35% for 2012. For the second quarter of 2012, we expect our revenues to be in the range of $76 million to $78.5 million, and we expect a steady sequential progression of revenue growth during the third and fourth quarters. Gross margin will be 47% to 47.5% during the second quarter, and we expect our gross margin to increase to approximately 48% during the second half of the year.
We expect our earnings per share to be in the range of $0.54 to $0.59, which includes a tax rate of 35%. And expect our earnings per share to increase throughout the year.
During the second quarter, we expect some softness in Southern European countries as well as continued weakness in critical care sales. As we already discussed in our previous call, the Slovakia plant will continue to put pressure on our gross margins throughout the entire year. However, we expect this impact to somewhat decrease during the second half of the year as we increase production volume. We expect our second quarter SG&A to be sequentially higher than in the first quarter due to increased sales and promotional costs and higher legal costs.
Our operating cash flow is expected to be approximately $40 million to $50 million in 2011 and we believe capital expenditures will be $13 million to $18 million in 2012. Now, operator, we are now ready to turn -- ready to open the call for your questions.
