macocha_score: MACOCHA Score for Difficult Intubation in ICU

Description

Calculates the MACOCHA score to predict the risk of difficult endotracheal intubation specifically in critically ill patients in the Intensive Care Unit (ICU). A score of 3 or greater identifies patients at high risk for difficult intubation.

Usage

macocha_score(mallampati_iii_iv, apnea_syndrome, cervical_spine_limited,
              mouth_opening_lt_3cm, coma_gcs_lt_8, hypoxia_severe,
              non_anesthesiologist)

Value

A list containing:

MACOCHA_Score

The calculated score (Range 0-12).

Risk_Category

"Low Risk" (Score 0-2) or "High Risk" (Score >= 3).

Recommendation

Clinical guidance for airway management preparation.

Arguments

mallampati_iii_iv

Numeric (0 or 1). Mallampati Score III or IV. (1 = Yes, +5 points).

Numeric (0 or 1). Obstructive Sleep Apnea Syndrome (OSAS). (1 = Yes, +2 points).

cervical_spine_limited

Numeric (0 or 1). Reduced mobility of the cervical spine. (1 = Yes, +1 point).

mouth_opening_lt_3cm

Numeric (0 or 1). Limited mouth opening (< 3 cm). (1 = Yes, +1 point).

coma_gcs_lt_8

Numeric (0 or 1). Coma (Glasgow Coma Scale < 8). (1 = Yes, +1 point).

hypoxia_severe

Numeric (0 or 1). Severe hypoxia (SpO2 < 80% despite preoxygenation). (1 = Yes, +1 point).

non_anesthesiologist

Numeric (0 or 1). Operator is a non-anesthesiologist. (1 = Yes, +1 point).
