hope_score_hypothermia: HOPE Score for Hypothermia Outcome Prediction

Description

Calculates the HOPE score to estimate the probability of survival in patients with hypothermic cardiac arrest undergoing Extracorporeal Life Support (ECLS) rewarming. The score uses age, sex, hypothermia mechanism (asphyxia vs non-asphyxia), CPR duration, serum potassium, and core temperature.

Usage

hope_score_hypothermia(age, sex, mechanism_hypothermia, cpr_duration_min,
                       potassium_mmol_l, temperature_c)

Value

A list containing:

HOPE_Score_Probability

The estimated percentage probability of survival to hospital discharge.

Recommendation

Guidance on ECLS utility based on the calculated probability.

Arguments

age

Numeric. Patient age in years.

sex

String. Patient sex ("Male" or "Female").

mechanism_hypothermia

String. Mechanism of hypothermia. "asphyxia" (e.g., submersion, avalanche) or "non-asphyxia" (e.g., exposure). Non-asphyxia is a positive predictor.

cpr_duration_min

Numeric. Duration of cardiopulmonary resuscitation in minutes.

potassium_mmol_l

Numeric. Serum potassium level in mmol/L.

temperature_c

Numeric. Core body temperature in degrees Celsius.

# Example 2: Poor Prognosis
# 60yo Female, Asphyxia (Drowning), CPR 90 min, K 8.0, Temp 30C
