Soldati et al. [
1] proposed the use of a wireless ultrasound unit for lung ultrasound, while others used non-wireless devices [
2]. The use of pocket-sized machines and wireless probes are encouraged, because these are easy to clean, transport, and disinfect, and therefore, may aid in limiting equipment contamination and viral spread [

6]. While useful for lung ultrasound and for mean patients, the image quality and capabilities of these devices are inferior compared to the more powerful machines typically used in the ICU, features that in fact are needed in many critically ill COVID-19 patients (e.g., for measuring the cardiac output, for measuring parameters of venous congestion and so on). Regardless the size of the device, and given that coronavirus persists in inanimate surfaces [
7], a careful equipment cleaning and disinfection should always be done for any equipment used. Quaternary ammonium compounds are compatible with most ultrasound machines and is highly effective against COVID-19 [
8]. Therefore, from a practical point-of-view, there is no need of advocating the use of miniaturized devices for infectological reasons providing the equipment is carefully cleaned and disinfected. Similar to others [
2], we maintained the image quality and capabilities of always using a conventional portable machine (Mindray M6®) dedicated to the COVID-19 ICU and equipped with three transducers: convex (2–5 MHz), phased-array (2–4 MHz) and linear (5–10 MHz) probes.
