A pаtient hаs severe аbdоminal pain. What is typically the mоst cоmfortable position for this patient?

Enrоute Phаse Scenаriо: The AEMT is dispаtched tо a local fitness center for a 58-year-old male who collapsed while using a treadmill. A bystander on scene reports that the patient is unresponsive and not breathing. The time of the call is 1412. The response time is estimated at 8 minutes. The AEMT is partnered with an EMT, and a fire department BLS engine crew is also en route. The patient is located inside the gym. It is a warm spring afternoon with moderate traffic in the area. The nearest hospital is 10 minutes away. Gym staff have been instructed to retrieve the on-site AED and bring it to the patient. OnScene Phase Scenario: The patient (approximately 80 kilograms) is found lying supine on the floor of a fitness center. The patient is unresponsive, pulseless, and not breathing. A bystander began chest compressions approximately two minutes before EMS arrival. Gym staff report that the patient had been jogging on a treadmill before suddenly collapsing. The AED has just arrived on scene. The AEMT confirms absence of a carotid pulse and initiates resuscitation efforts. High-quality chest compressions are continued, and a bag-valve mask is connected to high-flow oxygen to begin ventilation. The AED is attached, and the initial rhythm analysis indicates ventricular fibrillation shock advised. No signs of trauma are present. The patient has no known allergies. The patient’s medical history and medications are currently unknown. Post Scene Phase Scenario:  The patient (approximately 80 kilograms) remains unconscious following return of spontaneous circulation (ROSC) after 12 minutes of CPR and two defibrillation shocks. The patient’s skin is pale and cool, and there is no evidence of trauma. The advanced airway remains secured and in place, and the patient is ventilated with a bag-valve mask connected to high-flow oxygen. The carotid pulse is present at 84 beats per minute, and respirations are shallow at 8 breaths per minute. Pupils are 3 mm and reactive to light. The AEMT notes oxygen saturation at 89% with BVM ventilation. The patient is secured and prepared for transport. Vital signs are BP 106/70, P 84, R 8 (assisted), SpO₂ 89% on BVM, and T 98.6°F (37°C). No spontaneous movements or responses to verbal stimuli are observed. Why is it important to maintain oxygenation and ventilation in this post-cardiac arrest patient? 

Enrоute Phаse Scenаriо:  The AEMT is dispаtched tо a dentist’s office for a 32-year-old male who is reported to be weak, dizzy, and slightly agitated. The call was received at 1015. The estimated response time is 9 minutes. The AEMT is partnered with an EMT, and a BLS fire department engine crew is also en route. The patient is located inside the dental office. It is a cool spring morning with heavy rainfall in the area, and the temperature is 42°F (6°C). A small hospital is located 12 minutes from the scene, while the nearest comprehensive medical facility is 30 minutes away.  OnScene Phase Scenario:  The patient (70 kilograms) is seated upright in a dental chair and appears visibly diaphoretic. The office staff states that the patient seemed confused upon arrival and has become increasingly irritable and slow to respond. The patient has a history of diabetes, seizures, and hyperlipidemia, and was instructed to fast after midnight for a scheduled dental procedure. The patient takes insulin, carbamazepine, hydrocodone/acetaminophen (for dental pain), and atorvastatin. The patient has no known allergies to medications. There are no signs of trauma, and the patient is able to follow simple commands. Eyes are open, and the pupils are 5 mm and reactive to light. The patient’s skin is diaphoretic. The vital signs are: blood pressure is 156/90 mmHg, pulse is 124 beats per minute, respirations are 10 per minute, SpO₂ is 95% on room air, temperature is 98°F (37°C), and the blood glucose is 47 mg/dL. Post scene Phase Scenario: Following administration of Dextrose 50% IV, the patient (70 kilograms) becomes more alert and oriented. He states that he did not eat breakfast prior to the dental procedure and began feeling “shaky” shortly after arriving. The patient now appears weak but is conversational and cooperative. His skin remains slightly diaphoretic. There are no signs of trauma, and IV access remains intact in the left forearm. Eyes are open, and the pupils are 5 mm and reactive to light. The vital signs are: blood pressure is 138/86 mmHg, pulse is 102 beats per minute, respirations are 14 per minute, SpO₂ is 97% on room air, temperature is 98°F (37°C), and the blood glucose is 84 mg/dL. The patient agrees to transport for further evaluation.   Which of the following findings best confirms that the dextrose treatment has been effective?
