Winter's Formula — PaCO₂ Estimator
Estimate the expected PaCO₂ (mm Hg) for metabolic acidosis and check if respiratory compensation is adequate.

Typical lymphocyte %: 20–40% · Typical WBC: 4.1–10.9 ×10³ cells/µL. This tool provides approximate values for clinical use; always correlate with clinical context and lab reports.
Absolute Neutrophil Count (ANC) is a key measure of immune function, calculated from the total white blood cell count and the percentage of neutrophils (including both segmented neutrophils and bands). It is used to assess the risk of infection, particularly in patients undergoing chemotherapy, as a low ANC (neutropenia) can indicate a higher risk of infection. The ANC is guides treatment decisions, such as the initiation of antibiotics or the modification of chemotherapeutic regimens and is an important in the management of patients with conditions that affect white blood cell production or function.
Compute ANC from WBC and neutrophil percentages. Designed for clinicians and informed patients — mobile-first and printable.
