GRV can refer to a glycol recovery vehicle, which collects water and slush
The Glycol Recovery Vehicle, or GRV, is a specialised vehicle that collects slush, water, sand, and gravel containing spent de-icing fluid. It is designed to minimise the environmental impact of de-icing fluids, which can be harmful to the environment. The GRV sweeps up water and slush into a trough and moves it to the tank via screw conveyors, which are efficient and robust, negating the need for a vacuum. This also keeps weight and fuel consumption down, making the vehicle lightweight, fast, and manoeuvrable.
The GRV's broom suspension is designed to optimise surface contact and extend the lifetime of the brushes, reducing maintenance requirements. The hopper is also specially designed to hold liquids and solids like snow, sand, and gravel. This multi-purpose capability allows the GRV to collect de-icing fluids and other materials spread on airport aprons and ramps, preventing glycol run-off.
The Vestergaard Company, a leader in ground support equipment, has developed the GRV to promote environmental sustainability and resource efficiency. Their GRV has a fuel consumption that is over 50% lower than conventional vacuum sweepers due to its lack of auxiliary engines and vacuum fans. This reduced fuel consumption also contributes to the vehicle's lightweight and manoeuvrable characteristics.
The GRV's ability to recover de-icing fluids has a significant environmental impact, especially in the aviation industry, where it can be used by airlines, airports, and ground support companies. The recovered glycol can be recycled, further reducing environmental harm. The GRV's efficient collection of spent de-icing fluids and other materials contributes to a greener and more prosperous future by minimising the environmental footprint of industries that rely on glycol-based solutions.

GRV is used to abbreviate the 'Grav Jump' feature in the game Starfield
In the game Starfield, GRV is used to abbreviate the Grav Jump feature. This feature allows players to travel to other star systems using their ships. The amount of power allocated to the GRV feature determines the time required for activation, with more power resulting in quicker activation and launch. However, it is important to note that additional power does not increase the distance of the grav jump.
The Grav Jump feature is crucial for escaping unfavorable ship battles or ambushing enemy ships. By allocating power to the GRV, players can quickly escape pursuing enemies or retreat from a losing battle. This is particularly useful as enemies tend to target the grav drive, and a faster escape can improve the chances of survival.
To perform a grav jump, players must engage the RV drive, found in the bottom left of the HUD, and power at least one node into it. They can then open the map menu, zoom out, and select the desired star system to travel to. It is worth noting that fuel management is essential for grav jumps, as insufficient fuel capacity may restrict travel to certain systems.
Players can upgrade their fuel capacity or grav jump distance through various means. One option is to acquire HE-3 Tanks, a ship upgrade that enhances helium storage capacity, allowing for longer journeys. Alternatively, players can obtain a better ship with improved Grav Jump Distance or stronger Grav Drives, enabling them to travel further with fewer jumps.
Understanding the mechanics of the Grav Jump feature, including the role of the GRV abbreviation, is essential for effective navigation and exploration in the Starfield game.

GRV can stand for 'Gastric Residual Volume', which is used to assess feeding tolerance
GRV stands for Gastric Residual Volume, which is the amount of liquid drained from a stomach following enteral feeding. This liquid consists of infused nutritional formula or water, and secreted gastrointestinal juice. GRV monitoring is a common practice in intensive care units (ICU), especially in critically ill patients, to assess feeding tolerance.
Feeding intolerance (FI) is a sign of gastrointestinal dysfunction, which can lead to reduced enteral nutrition (EN) intake. It is highly prevalent in ICU patients and is associated with worse outcomes. Therefore, it is crucial to assess feeding tolerance to improve patient safety. GRV monitoring is a simple and effective method to evaluate FI. A high GRV indicates a full stomach, and administering more nutrients through a feeding tube in such cases can lead to vomiting and an increased risk of aspiration pneumonitis.
The incidence of FI is about 27% in general ward patients and 36% in ICU patients. The leading cause of FI is delayed gastric emptying, which can be assessed by various methods such as scintigraphy, paracetamol absorption tests, ultrasound, and gastric impedance monitoring. However, in clinical practice, GRV measurement is commonly used to evaluate gastric emptying. GRV monitoring enables clinicians to identify delayed gastric emptying early and implement strategies to minimize the adverse effects of FI.
The frequency of GRV measurement varies, with some institutions recommending assessments every four to six hours, while others suggest continuous monitoring. The threshold for interrupting EN also differs, with some sources suggesting a GRV of 200 ml as a concern, while others use 400 ml or 500 ml as the cutoff. GRV monitoring has benefits, such as early detection of feeding intolerance and preventing pulmonary aspiration. However, it also has disadvantages, including the lack of evidence of its efficacy in some cases and the potential for unnecessary interruptions in enteral nutrition.
In conclusion, GRV monitoring is a valuable tool for assessing feeding tolerance, especially in critically ill patients. It helps identify delayed gastric emptying and guides enteral feeding rates to improve patient safety. However, it is important to standardize GRV monitoring practices and thresholds to ensure effective patient care.
