ABSTRACT
The objective of this study was to verify the feasibility of using an Oxygenation Device with Reservoir and Positive End-Expiratory Pressure (ODRPEEP; DORPEEP in Spanish) and to analyze its safety with respect to mask leaks and carbon dioxide retention measured upon expiration. A quasi-experimental pilot study was designed with eight volunteers in two experiments to determine the degree of leaks from the device, according to the observation of water vapor particle diffusion, on the one hand, and of thermal images on the other. The results from this study showed that the mask from the DORPEEP© device at is tightest fit provided an adequate seal, although not fully airtight. In the thermal images and in the experiment with water vapor in our study, dispersions were mainly observed in the lower area in individuals with a beard. The DORPEEP© device was shown to have only slight leaks.

OBJECTIVE: The objectives of this study were (a) to determine the physical impact of the personal protective equipment (PPE) used in COVID-19 care, specifically the impact on the hydration state of the temperature and the comfort of the healthcare workers who use it, and (b) to show the high-fidelity simulated environment as an appropriate place to test the experimental designs to be developed in real environments for COVID-19. BACKGROUND: All healthcare staff use full PPE in the care of COVID-19 patients. There are problems, such as excessive sweating, which have not been quantified thus far. METHODS: A descriptive pilot design was used in a simulated high-fidelity setting. There was paired activity, with mild-moderate physical activity, between 45 and 60 min continuously, with the COVID-19 PPE. Sixteen intensive care nurses were selected. The before-after differential of weight, thirst, weight use of the PPE, body temperature, thermal body image, general and facial warmth sensation, and perspiration sensation were measured. RESULTS: All subjects lost weight in the form of sweat with both PPEs during the simulation scenario, with a mean of 200 g (0.28% of initial weight), and increased thirst sensation. Body thermal image increased by 0.54 °C in people using the full COVID-19 PPE. CONCLUSIONS: The use of PPE in the management of critically ill COVID-19 patients generates weight loss related to excessive sweating. The weight loss shown in this pilot test is far from the clinical limits of dehydration. The use of ventilated PPE, such as PAPR, reduce the body temperature and heat sensation experienced by the users of it; at the same time, it improves the comfort of those who wear it. The simulated environment is a suitable place to develop the piloting of applicable research methodologies in future studies in a real environment.

Objective: To assess the efficacy of virtual reality (VR) in cardiopulmonary resuscitation (CPR) training. Method: Experimental, analytic, cross-sectional study of a CPR training method using VR. Participants were randomly assigned to train in a control group or a VR group. Results: The mean (SD) scores on a scale of 10 after training were 9.28 (0.91) in the VR group and 7.78 (1.63) in the control group, for a mean difference of 1.49 (95% CI, 0.96-2.02; P<.001). The VR group achieved a mean of 97.5 (9.7) compressions/min, versus 80.9 (7.7) compressions/min in the control group, for a mean difference of 16.6 compressions/min (95% CI, 15.0-18.2; P=.003). The mean compression depth in the VR group was 34.0 (6.5) mm, versus 27.9 (4.9) mm in the control group, for a mean difference of 6.7 (95% CI, 5.7-7.8; P<.001). Conclusion: Training with VR can improve CPR theoretical knowledge and practical skills

OBJECTIVES: The main objective of the study is to determine the efficiency in the execution of the START (Simple Triage and Rapid Treatment) triage, comparing Virtual Reality (VR) to Clinical Simulation (CS) in a Mass Casualty Incident (MCI). The secondary objective is to determine the stress produced in the health professionals in the two situations described. MATERIALS: A comparative study on the efficiency and the stress during triage in a MSI was conducted. The basal and post levels of salivary α-amylase (sAA) activity were measured in all the participants before and after the simulation. RESULTS: The percentage of victims that were triaged correctly was 87.65% (SDâ¯=â¯8.3); 88.3% (SDâ¯=â¯9.65) for the Clinical Simulation with Actors (CSA) group and 87.2% (SDâ¯=â¯7.2) for the Virtual Reality Simulation (VRG) group, without any significant differences (pâ¯=â¯0.612) between both groups. The basal sAA was 103.26 (SDâ¯=â¯79.13) U/L with a significant increase (pâ¯<â¯0.001) with respect to the post-simulation levels (182.22, SDâ¯=â¯148.65â¯U/L). The increase of sAA was 80.70 (SDâ¯=â¯109.67) U/mL, being greater for the CSA group than the VRG group. CONCLUSION: The results show that virtual reality method is as efficient as clinical simulation for training on the execution of basic triage (START model). Also, based on the sAA results, we can attest that clinical simulation creates a more stressful training experience for the student, so that is should not be substituted by the use of virtual reality, although the latter could be used as a complementary activity.
