Metabolic fatigue Nutritional, Metabolic, Endocrine

Interventions

The proposed practical case is the same, a cardiac arrest in which the personnel present in the scene (1 rescuer) must perform the reanimation techniques for 10 minutes until the arrival of the specia

Design outcomes

Primary

Measure	Time frame
The following are assessed before the participant performs the simulation: 1. Respiratory frequency, assessed using clinical observation 2. Oxygen saturation, assessed using an Masimo Rad 7 3. Heart rate, assessed using a Physio LifePAK® 15 monitor 4. Blood pressure, assessed using a Physio LifePAK® 15 monitor 5. Tympanic temperature assessed using a Braun model ThermoScan® PRO 6000 6. Lactic acid levels, assessed using an Accutrend® Plus meter 7. Blood glucose, assessed using an Accu-Chek® Aviva 8. pH, using saliva strips 9. Hemoglobin level, assessed using an Masimo Rad 7 10. Perfusion index, assessed using an Masimo Rad 7 The following are assessed at the moment the participant performs the simulation every two minutes: 1. Respiratory frequency, assessed using clinical observation 2. Heart rate, assessed using a Physio LifePAK® 15 monitor 3. Lactic acid levels, assessed using an Accutrend® Plus meter 4. pH, using saliva strips 5. Quality level of resuscitation, using the Little Anne QCPR simulator (Laerdal) with QCPR software The following are assessed at the participant performs the simulation, after 10 minutes of rest: 1. Respiratory frequency, assessed using clinical observation 2. Oxygen saturation, assessed using an Masimo Rad 7 3. Heart rate, assessed using a Physio LifePAK® 15 monitor 4. Blood pressure, assessed using a Physio LifePAK® 15 monitor 5. Tympanic temperature assessed using a Braun model ThermoScan® PRO 6000 6. Lactic acid levels, assessed using an Accutrend® Plus meter 7.
