Although the technology has advanced in recent times the noise levels produced by such devices remain high. Exposure to excessive noise in intensive care may cause hearing problems for both staff and patients following long-term exposure. We investigated the noise level in decibels produced by a SensorMedics 3100B ventilator SensorMedics Bilthoven the Netherlands . The maximum total noise level recorded was 85 decibels with an average of 75 decibels over a 12-hour period. These daily noise levels exceed the minimum required for action to be taken by employers according to regulations operating within the United Kingdom. We suggest three strategies for dealing with this issue that aim to reduce potential harm to both patients and staff. First reduce the noise produced by oscillators. This should be done in conjunction with equipment manufacturers. Second reduce the potential for damage to patient s hearing by the provision of ear protection and minimise ototoxic drug use whilst oscillation is employed. Although this may lead to difficulties in patient communication in reality those receiving high-frequency oscillation are normally deeply sedated and paralysed. Finally reduce the risks to staff working with these patient groups. The provision of staff ear protection would be problematic so other strategies should be used. These could include mandatory training limiting time spent nursing oscillated patients using rotational staffing policies and excluding those with pre-existing hearing problems.
