Why You Should Replace Your Hot-Wire Anemometer

Hot-wire anemometers are widely used throughout hospitals. Although their initial accuracy remains undisputed, a hot-wire anemometer's accuracy is not stable over time. Hot-wire anemometers must be cleaned at regular intervals to remain an accurate and effective solution for monitoring room pressure. Without regular cleaning and calibration, the accuracy of a hot-wire anemometer decreases significantly over time.

Which Hospital Spaces Require Pressurization?

Proper room pressure and airflow are crucial for maintaining critical environments in hospitals. When talking about pressurized hospital spaces, the most well-known are operating rooms and isolation rooms. However, these are not the only two pressurized spaces within a hospital. ASHRAE Standard 170 details 60 different types of rooms in a hospital requiring pressurization. Without proper room pressurization, hospitals put their accreditation by the Joint Commission in jeopardy.

8 Features to Help Reduce Nuisance Alarms

In a hospital environment, alarm fatigue is an increasingly prevalent issue. Alarm fatigue is the sensory overload when clinicians are exposed to an excessive number of alarms; this can result in staff ignoring alarms, particularly if different devices employ similar sounds or frequencies. Nuisance alarms are those not representative of a patient in danger but come from devices that don't allow configuration for non-critical circumstances.

Models ASL and ASM: Pressure Transducers Designed for Your Aerospace Test Equipment


Test & Measurement application requirements are usually more rigorous than generic industrial specifications. Pressure measurement solutions for Test Stands require much higher accuracy, higher repeatability, and long-term stability. Durability and mechanical protection are often key specifications in these applications as well.

Should You Monitor Particles Between Certifications?

Twice a year, many critical environments - such as compounding pharmacies and cleanrooms - undergo particle certification. To obtain room certification, either a minimum sample volume (as written in the EC GMP Annex 1) should be taken, or the sequential sampling technique (as identified in both FS209E and ISO 14644-1) should be used. However, since this particle certification usually occurs only every six months, many critical environments are unaware of their particle counts during the remainder of the year.

What is the Difference Between 1 cfm and 0.1 cfm?

Flow rate is important to consider when selecting a particle counter for a critical environment. The flow rate of a particle counter is the rate at which a pump draws air through the sample chamber, measured in cubic feet per minute (cfm). Two common flow rates for particle counters are 1 cfm and 0.1 cfm. Depending on the application, each flow rate can be valuable.

Everything You Need to Know About USP 800

USP 800 is the standard governing hazardous drugs and their handling during receipt, storage, compounding, dispensing, administration, and disposal of both sterile and nonsterile preparation. USP 800 is in place to protect personnel and environments from hazardous drugs compounds, such as those in chemotherapy drugs or radiopharmaceuticals. USP 800 focuses on the safe handling of hazardous drugs (HDs) to minimize the risk of exposure to healthcare personnel, patients, and the environment. A drug is considered hazardous if

Everything You Need to Know About USP 797

USP 797 is the standard in place governing the sterile preparation of compounded pharmaceuticals. USP 797 covers the compounding of both hazardous and nonhazardous drugs with a focus on the protection of sterile compounds and environments from contamination. This standard is in place to ensure patient safety and reduce risks associated with compounding pharmaceuticals, including contamination, infection, and incorrect dosage. The standard helps to guarantee patients receive quality drugs free from contaminates. This standard applies to all pharmacies that produce compounded sterile preparations (CSPs); this includes pharmacies within hospitals, radio or nuclear pharmacies, chemo units, and operating rooms. The goal of the standard is to prevent harm to patients resulting from microbial contamination, bacterial endotoxins, variation in the strength of ingredients, and chemical and physical contaminates.
