<prompt> According spaulding classification system of sterilization, following is true except ?Non-critical devices come into contact with intact skinSemicritical equipment need low-level sterilizationSemi-critical devices come into contact with non-sterile mucous membranes or non-intact skinCardiac catheter is critical equipment  <response>: Ans. is b i.e., Semicritical equipments need low-level sterilization Spaulding system of sterilization Spaulding system is a strategy for reprocessing contaminated medical devices. The system classifies medical devies as critical, semicritical or noncritical based on the risk of contamination on a device to patient safety. The system also establishes three levels of germicidal activity high, intermediate, and low for disinfection strategies with the three classes of medical devices. Class Definition example Level of disinfection Critical equipmentdevice Equipmentdevice that enters sterile body tissues Sterilization Examples : - Surgical instruments, Resection handle, endoscopes that Sterilization results in the destru? ction of all forms of microbial life enter sterile body cavities including spores, bacteria, viruses Laproscopes, ahroscopes, cardiac catheters, colposcopes. fungi Semicritical equipment Equipmentdevice that comes in High level disinfection HLD device contact with non-intact skin or High level disinfection destroys mucous membranes but do not vegetative bacteria, fungi, viruses penetrate them It does not destroy bacterial spores Examples : - Laryngoscopes, vaginal High level of disinfection can be speculum, gastroscope, colonoscope, bronchoscopes, USG probe, anesthesia done by 2 glutaraldehyde, 6 H202, Pasteurization, 0.2 equipment, ear cleaning equipment. Peracetic acid Noncriticalequipment Equipmentdevice that touches only Low or intermediate level disinfection device intact skin and not mucous membranes Kill most vegetative bacteria and Examples : - Stethoscopes, ECG some fungi as well as enveloped electrodes, Blood pressure cuffs, electronic thermameters, environmental lipid viruses Does not kill mycobacterial or surfaces bacterial spores Low level disinfection can be done by 3 H20,, 60-95 alcohol, hypochlorite, or iodophors
