Intensive Care Calculators

Intensive care calculators are essential instruments for intensivists, physicians, and ICU nurses in managing critically ill patients. They enable calculation of mean arterial pressure (MAP), severity scores such as APACHE II and SOFA, sedation assessment using RASS scale, delirium detection with CAM-ICU, and prognosis estimation in critical patients. Based on intensive care medicine guidelines, sepsis protocols, and robust scientific evidence, these calculators facilitate decision-making in critical situations, stratify risk, guide resource allocation, and improve outcomes in intensive care patients through systematic monitoring and data-driven interventions.

When to Use These Tools

MAP calculation to guide vasopressor therapy in shock
Severity stratification with APACHE II at ICU admission
Sequential assessment of organ dysfunction with SOFA score
Sedation level monitoring using RASS scale
Early detection of delirium in ICU through CAM-ICU
Prognostic assessment for discussion with families

Clinical Benefits

Objective stratification of severity and prognosis

Standardization of assessments among ICU professionals

Early detection of clinical deterioration in critical patients

Guidance of specific therapies based on validated scores

Improvement in communication between team and family about prognosis

Support for clinical research and quality assessment in ICU

Frequently Asked Questions

What is the importance of SOFA score?

The Sequential Organ Failure Assessment (SOFA) evaluates dysfunction of 6 organ systems and is used to define sepsis, monitor evolution, and estimate mortality. An increase of 2 points defines sepsis. It is calculated daily to detect worsening or improvement of organ function.

Ideal MAP in critical patients?

Target MAP is generally ≥65 mmHg in sepsis and shock. In chronic hypertensive patients, MAP >70-75 mmHg may be considered. In intracranial hypertension, MAP >80 mmHg may be necessary. Always individualize according to clinical condition and response to therapy.

How to use CAM-ICU properly?

The Confusion Assessment Method for ICU (CAM-ICU) should be applied when the patient is RASS ≥-3. It assesses acute onset, inattention, disorganized thinking, and altered level of consciousness. Positive if criteria 1+2 and 3 or 4 present. Apply daily in all ICU patients.
