Summary
User requirements for in-hospital cardiopulmonary resuscitation (CPR) support apps were studied. Key features for CPR apps include rhythm check reminders, drug alerts, and pediatric/adult differentiation for better usability.
Area of Science:
- Medical Informatics
- Human-Computer Interaction
- Emergency Medicine
Background:
- User requirements for in-hospital cardiopulmonary resuscitation (CPR) support applications remain under-researched.
- A mixed-methods approach was employed to investigate usability, functionality, and design preferences.
Purpose of the Study:
- To identify essential features for in-hospital CPR support apps based on healthcare professional expectations.
- To evaluate the CprPrototype app against identified user requirements.
Main Methods:
- A mixed-methods research design incorporating semistructured interviews, observations during Advanced Life Support (ALS) training, and a Kano model-based questionnaire.
- Data collection involved 83 physicians and nurses for the questionnaire, 15 for observation, and 5 for interviews.
Main Results:
- Kano questionnaire analysis revealed 53% of requirements as indifferent, 29% as attractive, and 18% as one-dimensional.
- Qualitative feedback highlighted user needs in areas such as time tracking, documentation, and app design improvements, with noted differences between physician and nurse preferences.
Conclusions:
- Essential features for CPR support apps include rhythm check reminders, resuscitation drug alerts, and pediatric/adult differentiation.
- Attractive features enhancing user satisfaction encompass single-sided function access, patient journal integration, automatic time recording, a metronome for chest compressions, and data export to registries.

Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

266
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

315
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

272
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
