College Math & Statistics for Respiratory Therapy: Algebra or Stats?- why respiratory therapy programs require math, how to decide between college algebra and statistics, and how to complete the requirement online.
Math is a near-universal prerequisite for respiratory therapy school — but unlike anatomy and physiology, where the requirement is almost always the same two courses, the math requirement comes in more than one form. Some programs require college algebra, some require statistics, and some accept either. Figuring out which one your program wants is the first and most important step.
This guide explains why respiratory therapy programs require math, how to make the algebra-versus-statistics decision, what each course covers and how it connects to respiratory care, and how you can complete the requirement online. Math sits alongside anatomy and physiology, microbiology, and chemistry on the prerequisite list, and you can verify any program’s exact requirement through the Commission on Accreditation for Respiratory Care (CoARC).
Short answer: Almost all respiratory therapy programs require a college-level math course, completed with a grade of C or higher. Which course depends on the program: many associate programs require college algebra, while bachelor’s programs and a growing number of associate programs require — or accept — introductory statistics. At PrereqCourses.com these map to MATH 107 (College Algebra) and MATH 220 (Statistics), so you can take whichever your program specifies.
Yes — essentially every respiratory therapy program requires a college-level math course. Math underpins both the coursework and the daily work of the profession, from medication dosing to ventilator settings. The open question is rarely whether you need math; it is which math course satisfies the requirement.
A few patterns are worth understanding before you choose a course:
Because the specific course matters, confirm exactly which math your target program requires — algebra, statistics, or either — before you enroll.
When a program gives you a choice, or when you are weighing programs that differ, the decision comes down to what your program accepts and where you may be headed. Here is how to think it through:
| If your program… | Then… |
|---|---|
| Specifies college algebra (or “intermediate algebra or higher”) | Take college algebra (MATH 107). A higher-level algebra course will also satisfy it. |
| Specifies statistics | Take introductory statistics (MATH 220). Algebra will not substitute for a statistics requirement. |
| Lets you choose either | Consider your strengths and plans — see the guidance below. |
| Is a bachelor’s program or you may pursue one later | Statistics is often the safer choice, since it more commonly fits bachelor’s-level and general-education requirements. |
If your program lets you choose, a few practical considerations help:
The one rule that always holds: when a program names a specific course, take that course. Substituting algebra for a statistics requirement (or vice versa) is the most common — and most avoidable — prerequisite mistake.
The math in respiratory therapy is not abstract — it shows up at the bedside every day. Respiratory therapists calculate doses, set and adjust equipment, and increasingly interpret data and research. The required course is where those skills are first built.
A few examples of where math shows up in the work:
| Respiratory care task | Math it draws on |
|---|---|
| Calculating ideal body weight and tidal volume | Formulas, ratios, and unit conversions — core algebra skills used to set safe ventilator parameters. |
| Determining oxygen tank duration | Rates and proportional reasoning to estimate how long a gas supply will last at a given flow. |
| Medication and solution dosing | Concentrations, ratios, and basic equation-solving to prepare and administer inhaled medications accurately. |
| Reading research and quality data | Statistics — means, variability, probability, and interpreting study results — central to evidence-based practice. |
| Interpreting test results and trends | Graphs, percentages, and basic data interpretation used in pulmonary function testing and patient monitoring. |
Notice the split: bedside calculations lean on algebra, while research literacy and data interpretation lean on statistics. That is part of why programs differ on which course they require — and why statistics has been gaining ground as healthcare leans further into evidence-based practice. For a broader sense of the profession, the American Association for Respiratory Care (AARC) is the field’s main professional organization.
Both courses are college-level and transfer-oriented, but they build different skills. Organization varies by institution, but the typical content looks like this:
Most modern statistics courses are accessible to students who have completed basic algebra and emphasize interpretation over heavy computation — which is part of why many programs find it a good fit for healthcare students.
Yes — both college algebra and introductory statistics are widely available online and translate well to a self-paced format. Unlike the science prerequisites, math courses generally do not involve a lab, which makes them especially well-suited to online study and often among the easier prerequisites to complete remotely.
Before enrolling in any online math course, confirm that it meets these conditions:
A note on placement: some programs or institutions ask you to demonstrate algebra readiness (through a placement test or prior coursework) before enrolling in college algebra or statistics. If it has been a while since your last math course, a quick refresher can make either course go more smoothly.
At PrereqCourses.com, the respiratory therapy math requirement is satisfied by MATH 107 (College Algebra) or MATH 220 (Statistics) — self-paced, online courses delivered through our regionally accredited university partner, with an official transcript you can submit to your program. Take whichever your program specifies, or whichever you choose if your program accepts either.
| Course | Satisfies | Best when your program… |
|---|---|---|
| MATH 107 | College algebra requirement | Specifies algebra, or you want the strongest foundation for clinical calculations. |
| MATH 220 | Statistics requirement | Specifies statistics, or you may pursue a bachelor’s degree and want a course that often counts toward general education. |
What makes the format work for respiratory therapy applicants:
Important — confirm the course first: because programs differ on whether they want algebra or statistics, send the MATH 107 and MATH 220 course descriptions to your target program’s admissions office and confirm which one they require before you enroll. A short email ensures the credit will count toward your application.
Is math required for respiratory therapy school?
Yes, almost universally. Nearly every respiratory therapy program requires a college-level math course. What varies is which course — college algebra, statistics, or either.
Should I take college algebra or statistics?
Take whichever your program specifies. If it lets you choose, statistics is often the safer pick for bachelor’s-bound students and frequently doubles as a general-education requirement, while algebra gives a strong foundation for clinical calculations.
Will algebra satisfy a statistics requirement, or vice versa?
Generally no. If a program names a specific course, you usually must take that course. Substituting one for the other is a common prerequisite mistake, so confirm before enrolling.
Can I take math online for respiratory therapy school?
Yes. Both college algebra and statistics are widely available online and, because they typically have no lab, are well-suited to self-paced study. Confirm the credit is regionally accredited and transferable.
What grade do I need in math?
A grade of C or higher is the typical minimum. Admission can also weigh your grades in required math and science courses, so a strong grade helps a competitive application.
Do I need to finish math before applying?
Often, yes — many programs expect math to be completed before applying or before core respiratory therapy coursework begins. Check your program’s timeline and plan accordingly.
Math is one of the most consistent respiratory therapy prerequisites — almost every program requires it — but the specific course varies between college algebra and statistics, with statistics increasingly common. The math itself is practical, not abstract: algebra powers bedside calculations, and statistics powers the research literacy that modern healthcare expects. Completing the requirement online, through regionally accredited and self-paced coursework, lets you satisfy it on a schedule that works for you, as long as you take the course your program actually requires. After you graduate from a CoARC-accredited program, the National Board for Respiratory Care (NBRC) administers the exams that lead to credentialing and licensure.
