The coronavirus disease 2019 (COVID-19) pandemic has implications for cardiopulmonary resuscitation (CPR). Chest compression is an aerosol generating procedure that is associated with a high risk of disease transmission to healthcare workers (HCWs) [1]. Before commencing CPR, guidelines recommend usage of a minimum respiratory personal protective equipment (PPE), "an FFP3 mask (FFP2 or N95 if FFP3 is not available)" [1].Adherence to guidelines may have been challenged in two scenarios. First, there was an "inadequate quantity" (supply) of N95 masks during this pandemic. This rendered the HCWs unable to physically adhere to the guidelines. Second, masks may have been or may have been perceived to be of "inadequate quality" for several reasons [1]. The N95 mask has a lower filtration performance than the first-choice FFP3 mask, i.e., 95% vs. 99% [1], although the clinical significance of this is unknown. Additionally, counterfeit and poor quality N95 masks are being sold. Since chest compression involves vigorous movements, it may lead to poor mask seal, decreased protection rates, and mask failure including strap slipping [2]. Finally, N95 masks undergoing extended use and reuse are associated with disease transmission and decreased functionality [3].Ethical dilemmas and confusions arise in both scenarios. In the "inadequate quality" scenario, the HCW is expected to perform a duty (CPR) adhering to the guidelines (wearing a N95 mask). Hence, it is uncertain whether the HCW should proceed with an actual or perceived "inadequate quality" PPE. Moreover, existing PPE guidelines are not specific to CPR, and some guidelines recommend powered air-purifying respirators (PA-PRs) during CPR in patients with . As the risk of disease transmission during CPR is uncertain, it is unclear whether we should aim for the "maximum" level protection, or be satisfied with "adequate. " However, refusal to treat may result in disciplinary or legal action against the HCW.Various statements and considerations pertaining to a doctor's duty to treat (or not) are shown in Table 1. The duty to treat is guided by the ethical principles of beneficence, non-maleficence, autonomy, and justice [5,6]. As these principles apply to the patient, HCWs and society, there may be conflicting priorities. HCWs have an obligation to prevent self-infection and onward transmission of infections to other patients, their colleagues and relatives, and the wider community [1]. Further, the ethical principle of justice takes into account the right of not being killed by another human being [6] (with a serious infectious disease). Justice also requires hospitals to provide adequate PPE.Moreover, there are the doctrines of expressed consent, implied consent, special training, reciprocity, and professional oaths and codes [5]. Expressed consent includes signing of a contract on the basis that adequate PPE would be provided [5]. Arguments against
