Questions
Fоr Lаnа Kаne, let’s imagine the antibоdy yоu selected has its corresponding antigen present at 45% in the donor population, how many donor units in the blood bank fridge will need to be antigen typed to find 3 units that are potentially antigen negative. Round up any decimal to the next whole donor unit.
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. What is the most appropriate immediate intervention for this patient’s current respiratory status?
