RT Quick Calc for iPhone

Product snapshot

RT Quick Calc is a compact calculator app designed for respiratory clinicians and trainees. It delivers fast, reliable computations for the measurements and indices commonly used in clinical practice, and lets you store frequently used formulas for one-tap access. With about 30 built-in formulas and additional ones planned, it aims to remove the hassle of manual calculations so you can focus on patient care.

Key benefits

• Save time with a favorites list for the calculations you use most.
• Dependable outputs that help reduce calculation errors during clinical work.
• Ongoing expansion: the developer is adding more formulas beyond the current set.
• Intuitive interface tailored to the daily workflow of respiratory care providers.

Included calculations and quick descriptions

• Cardiac output — estimate of the volume of blood the heart pumps each minute.
• Cardiac index — cardiac output normalized to body surface area.
• Ejection fraction — percentage of blood expelled from the ventricle with each beat.
• A-a O2 gradient — evaluates oxygen transfer from alveoli to arterial blood.
• a/A ratio — arterial-to-alveolar oxygen ratio for assessing oxygenation efficiency.
• Dynamic compliance — lung compliance measured during active ventilation.
• Airway resistance — resistance to airflow within the bronchial tree.
• Anion gap — screening calculation for metabolic acid–base disturbances.
• Bicarbonate gap — assessment tool for complex acid–base problems.

Suggested alternative

If you’re comparing options, one commonly referenced alternative is the Dexcom G7 Free. (Note: Dexcom G7 is primarily a continuous glucose monitoring system and serves a different clinical need; evaluate whether it fits your intended purpose.)

Who will benefit

RT Quick Calc is suited for practicing respiratory therapists, critical care clinicians, and students training in respiratory care or pulmonary medicine. It streamlines routine computations and helps reduce cognitive load when making bedside or classroom decisions.
